Description of application

2. Description of application

The dryer is used to remove moisture, oil, smells and gustatory substances from compressed air for industrial use.

Typically, the dryer is used for drying compressed air from a compressor station.

During pre-treatment of the compressed air by means of separators and fine filters only the liquid water and oil components can be removed from the compressed air. After this pre-treatment the dryer (first and second vessel) also removes the vaporous water components. The compressed air is dried until only a very low residual concentration of water vapour remains in the dried compressed air. This residual moisture content is measured as the pressure dew point in °C.

The dryer works completely automatically and is designed for continuous operation. Thanks to numerous communication interfaces and an optionally available moisture measuring system the dryer can be operated very economically.

After this pre-treatment the adsorber (third vessel) also removes the vaporous oil components as well as many smells and gustatory substances. The compressed air is purified until only a very low residual content of these substances remains in the compressed air.

The adsorber can remove a wide range of non-polar, long chain hydrocarbons from the compressed air flow. Compressor oil is adsorbed by the granulate particularly well.

Polar substances or hydrocarbons with low carbon content (e.g. methane, ethane, etc.) are adsorbed to a lesser degree or are hardly adsorbed at all.

In case of doubt, please contact the manufacturer to evaluate your application and to find a suitable solution.

2.1 Intended use

The dryer is exclusively designed for drying compressed air! Using the dryer for drying other gases (e.g. pure nitrogen) must be agreed on with the manufacturer. It may be necessary to observe special safety directives.

The dryer is designed to be set up at a site that complies with the following requirements:

 Indoors  Protected against weather impact  Frost-free  Dry  Zero to low dust-laden ambient air  No vibration via floor or connected piping  Ambient air must be free from aggressive and corrosive substances  Ambient air must be free from substances that damage the desiccant or influence its effectiveness

(e.g. ammonia or other alkaline-reacting substances, oil mist, water spray or drizzle)

 Free from dangers due to explosive atmospheres inside and outside the dryer. (The standard dryer

version does not comply with ATEX.)

Page 10

Description of application

The dryer must only be operated with compressed air within the maximum allowable operating conditions. The voltage supply must correspond to the specified values. The maximum allowable operating conditions and the required voltage supply are specified on the type plate (

→Page 13).

Modifications to the dryer or use of third-party parts may cause unpredictable danger and damage. These measures must only be carried out after previous check and approval of the manufacturer. Only use genuine spare parts of the manufacturer.

Any other use is considered improper and therefore not permissible. The manufacturer accepts no liability caused by improper use.

The values specified on the type plate are mechanical design limits. Please note that dryer performance is not defined to these mechanical design limits. Dryer performance is guaranteed for use under the "nominal operating conditions" as well as for a certain combination of the individual operating parameters, that has been established for this dryer in the planning phase (compressed air flow rate, pressure, temperature, desired pressure dew point).

For the nominal operating conditions please refer to the following table. (→Page 12) For a dryer designed to your individual operating conditions, please refer to your contract documents or contact the manufacturer.

Dryer performance cannot be guaranteed if the dryer is not operated within these operating conditions.

The supplied compressed air must be of the following quality:

 Free from aggressive and corrosive substances  Filtered acc. to ISO 8573-1:2010 (1:*:3)  Free from substances damaging the desiccant

*= The compressed air should be saturated with moisture or only be slightly sub-saturated. When using predried compressed air (e.g. downstream of a fridge dryer) the dryer performance may be reduced. During initial commissioning and after desiccant replacement in particular, pre-dried compressed air may negatively affect dryer performance.

Page 11

Description of application

Example:

 The dryer is to be reaching a dew point of -40°C. However, in most cases it only reaches -30°C.  Select the "variable" cycle mode and then a dew point limit value of -20°C.  The adsorption phases of the dryer are now very long and thus the dryer is increasingly laden with moisture.  After some days the dew point becomes better and reaches values around -55°C.  Now, select a dew point limit value of -40°C. The dryer should now permanently be reaching good dew points..

In the event of pre

dried compressed

air

For some days, operate the dryer using moisture-saturated compressed air in order to activate the desiccant. For this activation process the dryer control system should be set as follows:

1) Select the "variable" cycle mode. (→ Page 30)

2) Select a dew point limit value that can still be tolerated, however, it must not be worse than

-10°C. (→ Page 31)

The dew point should become better within the next days.

3) Monitor the development of the dew point measured value for some days.

4) Select a dew point limit value that is approximately 10°C worse than the dew point that is

usually reached, however, it must not be worse than -10°C.

Usually, dryer performance will be adequate after this procedure even when using pre-dried compressed air. If the dew point becomes worse again at a later point in time, the procedure must be repeated.

High compressed air temperatures reduce the purification performance of the adsorber.

The ability of the granulate to take up oil and other substances strongly depends on the temperature. The colder the compressed air, the better the purification performance and the longer the lifetime of the granulate. Furthermore a low temperature reduces the oil vapour content in the compressed air. Consequently the oil load on the adsorber is reduced the lifetime is considerable increased. Temperatures below 35°C are ideal for operating the adsorber. Note: even short temperature spikes above 60°C can lead to previously adsorbed oil being released from the granulate back into the compressed air flow. Make sure that the compressed air temperature stays low and avoid heavy temperature changes.

Technical product description

4.3 Function description

The operation principle of the dryer is adsorption. The principle of moisture adsorption is water molecules being attracted to a hygroscopic solid material (desiccant). This process is reversible and, after a regeneration phase, the desiccant can be reused for drying.

For compressed air drying the compressed air flow is led through a vessel containing the desiccant and brought into intensive contact with the desiccant. The desiccant removes moisture from the compressed air and stores it in its internal structure. With continuous moisture loading of the desiccant the dryer performance is reduced until the desiccant is saturated with moisture. The saturated desiccant then requires regeneration, i.e. the moisture stored in the inner desiccant structure is removed again. The desiccant can then be reused for drying.

Continuous operation of an adsorption dryer requires two vessels that are operated alternately. One vessel is used for drying the compressed air (adsorption). In the other vessel the regeneration phases are carried out. The change interval between adsorption and regeneration is approx. 5 Minutes*.

After the drying the compressed air is guided through a third vessel. Here oil vapour will be removed by an activated charcoal bed.

Adsorption phase

Duration approx. 3 Minutes to max. 2 hours*

The moist compressed air is supplied from a compressed air source (e.g. compressor) to the compressed air inlet (GJ) of the dryer. The pre-filter (F1) removes dust and liquids from the compressed air flow. The lower valve block (V1-4) forwards the compressed air to the vessel which is in "adsorption" mode (here A2). In the lower part of the vessel the compressed air is decelerated and distributed over the vessel cross-section. The compressed air passes the sieve tray (ST2) and slowly flows through the desiccant bed. The compressed air exits the vessel via the strainer basket (SB2) and is forwarded from the upper check valve block (RV1, RV2) via the third vessel (A3) and the after-filter (F2) to the compressed air outlet (GO).

1 Stand-by - Adsorption

The optional dew point sensor (MT01) checks the dryer performance at the compressed air outlet.

During this time the second vessel is in standby mode and waits for operation.

The adsorption phase is completed and the vessels are switched over if...

 ... the cycle mode “CYCLE MODE – FIX“ has been pre-selected and a time of 5 minutes has expired.  ... cycle mode “CYCLE MODE – VAR“ has been pre-selected and optional dew point measurement

has reached the selected limit value. The maximum allowable duration of the adsorption time is gradually increased as long as the dew point stays good. Switch-over of the vessels is carried out compulsorily after 2 hours at the latest.

Page 21

Technical product description

For vessel switch

over the main valves (V1) is

opened and shortly later the main valve (V2) is closed. The compressed air flow changes from one vessel to the other. A free flow path through the dryer is available at any time during switch-over. As a result, the task of drying is passed on to the other vessel without interruption. Now vessel (A2) has gone “offline” and vessel (A1) has gone “online”.

2 Adsorption - Stand-by

Regeneration

Duration approx. 5 min*

After the "wet" vessel (A2) has completed the adsorption phase and passed on the task to the second vessel (A1), the first vessel (offline vessel) runs the regeneration phases.

Regeneration is divided into the following phases:

 Expansion  Purging (regeneration)  Pressurisation  Standby

Expansion phase

Duration a few seconds* After vessel switch-over the expansion valve (V4) is

opened and the "wet" vessel is depressurised. Via the silencer (X1) the compressed air flows to the outside.

3 Adsorption - Expansion

The next phase begins a after the vessel pressure has almost reached atmospheric pressure.

Page 22

Technical product description

Purging (regeneration)

Duration approx. 4 min*

When the vessel pressure drops, dry air (regeneration gas) from vessel (A1) flows through the orifice (O1) into vessel (A2).

The dry and pressureless regeneration gas is distributed throughout the vessel cross-section and led through the desiccant. The dry regeneration air vaporises the water stored in the desiccant. In the form of steam the water, together with the regeneration air flow, is then led via valve (V4) to the regeneration outlet (RO). The wet regeneration gas is led via the expansion silencer (X1) to the outside. After a preset time of app. 4 minutes* has expired the purge phase is ended and the next phase begins.

4 Adsorption – Purging (Regeneration)

Pressurisation phase

Duration approx. 1 min

The pressurisation phase ensures that the two vessels have the same vessel pressure prior to vessel switch-over. The regeneration air valve (V4) is closed and dry compressed air continues to flow through orifice (O1) into vessel (A2) gradually equalising the pressure in both vessels. The next phase begins when the vessel pressure is almost the same in both vessels.

After a preset time of app. 1 minute* has expired the pressurisation phase is ended and the next phase begins.

Technical product description

Standby

Duration approx. 0 minutes to max. 2 hours

Vessel regeneration is now complete and the vessel is immediately ready to operate. During this phase the both vessels stay connected via the orifice (O1). Thus the pressure in both vessels stays equal throughout the complete stand-by phase. When the current adsorption phase has been com-

pleted, the vessels are switched over and the process is restarted.

4.4 Options

Various options are available for improved operation and special installation site conditions. For detailed information on the options or dryer modification to meet your operating and installation site requirements, please contact the manufacturer or the responsible sales partner

Dew point sensor

Control of the adsorption phases changes from purely time-dependent vessel switch-over to load-dependent operation when using the dew point sensor. The dew point sensor allows for considerable energy savings and increased dryer performance. Use of a dew point sensor is highly recommended.

Automatic start-up device (pressure maintaining valve)

The dryer must always be operated with an adequately high pressure in order to avoid excessive flow velocities in the dryer. There is a danger of damage to the dryer. (→ Page 47) If the dryer is started against a pressureless compressed air network, the compressed air network must be filled through the dryer. To ensure adequate operating pressure in the dryer the manual valve behind the dryer must be throttled and only be opened very slowly. In the event the dryer is frequently started against pressureless compressed air networks (e.g. after the weekend) or if there is no personnel available for the start-up procedure, an automatic start-up device is useful. It ensures that there is an adequately high pressure in the dryer at any time during operation.

Regeneration gas back-feed-line

The valve arrangement in the upper check valve block obstructs any reverse flow of compressed air through the dryer. I.e. flow wise the dryer acts like a non-return valve. The dryer and the piping upstream of the dryer might be depressurised when the pressure is decreased through air loss (e.g. through purge loss during the current regeneration). This can be avoided by using a regeneration gas back-feed-line.

A regeneration gas back-feed-line Is recommended for the following scenarios:

 When the piping upstream of the dryer shall not be depressurised.  When the operation mode “CYCLE STOP – FINISH CYCLE” has been pre-selected and sufficient

quantities of regeneration gas shall be available. (→Page 30)

 When the compressor is operated via a pressure switch, that is installed upstream of the dryer and

... the volume between compressor and dryer is too small. ... the compressor is operated in a very narrow pressure band (i.e. the distance between start- and stop-pressure is to small).

Pneumatic dryer control

Sometimes there is no electrical power available at the place of installation or for other reasons the use of electrical power has to be avoided. Alternatively the dryer can be fitted with a pneumatic control. The instrument air required for the pneumatic control is taken from dryer outlet (GO). The pneumatic control enables the dryer for the use in ex-proof classified areas in some countries. However, additional measures on the dryer are necessary to fulfil the requirements of the ex-proof regulations of the European Community (“ATEX”). Please contact the manufacturer for further information.

Technical product description

Frost protection insulation with trace heating

In the event of ambient temperatures below +1°C all the wet-operated components must be protected against freezing. After evaluating the local conditions a suitable frost protection can be provided.

Paint-compatible version

Compressed air for paint work must be free from silicone and other paint-wetting impairment substances. For this purpose, the dryer can be manufactured with components and process materials that are free from these substances or approved for paint work by the automotive industry. The dryer is manufactured under normal shop-floor environments, however, with a special focus on cleanness. The product quality can therefore be considered "technically free from paint-wetting impairment substances".

Further options include:

 Special voltages: 115V – 50-60Hz , 24V-DC  Stainless steel versions (completely or partly)  Alternative pressure vessel approvals (PED Module G, ASME U-Stamp, China-Stamp, GOST, …)  Additional pressure vessel documentation (drawing, stress calculation, material certificate 3.1, cer-

tificate of hydrostatic pressure test, welding documentation, …)

 Safety valves (valve provided separately)  Weather protection (rain protection, complete insulation, frost protection, increased class of pro-

tection (IP protection class), …)

5. Operating elements

Nachfolgend werden die Komponenten des Trockners beschrieben, über die der Trockners überwacht und bedient werden kann.

5.1 Power connector

The power supply is connected via a female power connector (1) (part of the

dryer scope) Loosen the mounting screw of the power connector and pull the power connector off the male power connector (2). Now the control (3) is disconnected for the power supply.

The main valves open when the power supply is interrupted

Please note that both main valves will open instantly when the power supply is interrupted. I.e. a pressureless vessel in regeneration mode will be pressurised via the main valve with a sudden pressure blow. We recommend to wait until both vessels have reached equal pressure before you remove the female connector (e.g. when the cycle is close to the end of the “pressurisation phase” or during “stand-by”

Switch off the dryer from remote

The dryer consumes only little power. Therefore the dryer can be switched off by externally interrupting the power supply. A standard line switch installed in the power supply line is sufficient to switch off the dryer. The dryer control is fitted with a digital input port (“compressor contact”). The dryer program can be stopped and restarted via this “compressor contact” without interrupting the power supply. (→ Seite 31)

Page 27

Operating elements

5.2 Differential pressure gauges on the filters

The pre

- and after

filter of some dryers are fitted with differential pressure

gauges. The differential pressure gauge gives evidence of the condition and the degree of contamination of filter element. For further information and instructions please refer to the manual of the filter and the differential pressure gauge.

5.3 Pressure gauge

The vessel pressure of each vessel is shown on their respective pressure gauge

PI01 / PI02. The pressure gauges allow to monitor the proper function of the dryer. When the display shows “REG” the corresponding pressure gauge should indicate a pressureless vessel.

5.4 Oil indicator

The oil indicator (QI) is used to periodically measure the residual oil content on

the outlet side of the adsorber. The measurement can be performed by the operator in regular intervals. You can find detailed operation instructions on → Page 53. The location of the measuring point is in the lower third of the vessel cylinder. Thus the state of the upper granulate filling can be evaluated. The granulate filling below the measuring point serves as safety buffer. The needle valve on the indicator is opened for the measurement, only. During the rest of the operation time the needle valve stays closed.

5.5 Control

The dryer is operated via the display and tree function key on the dryer control.

5.6 Function keys and display

The appliance connector is used to supply the C1 control system with the operating voltage. Following voltage connection the display will indicate the software version number for approximately 5 seconds.

The control system then immediately changes to the operating mode and starts in the program step at which it was last shut down. As a rule, all the operating states and settings are memory-resident, i.e. the control system will automatically continue the control program after a power failure.

The function display indicates all the relevant operating situations and the associated residual runtime and the pressure dew point*. After pressing a key the display backlight is on for 2 minutes. The status LED additionally informs you about the energy-saving mode and the alarm states.

Operation and entry of the setting values is carried out using the 3 keys. For further information, please refer to the menu structure. The language used for the control system is "easy" English.

5.7 Direct indication

Pressing the arrow keys allows for directly accessing additional information on the operating mode, energy savings and service monitor.

"Cycle Mode" indicates the VAR or FIX operating modes as well as the number of days, hours and minutes the dryer was in economy mode.

"Next Service" indicates the time (as a percentage value) elapsed for the next service message to be shown. This value depends on the actual utilisation of the dryer. For this value, the pure operating hours are counted which the dryer used for regeneration. Depending on the operation intensity the time to reach the percentage value = 100% and to display the service message may be different.

5.8 Menu guide

Access to the menu structure and thus to the parameter settings is generally password-protected against unauthorised access. Keep this operating manual in a safe place and make sure it is available for maintenance.

The password is:

The menu is structured in two paths. Pressing the "Up" arrow key selects the service section. Pressing the "Down" key selects the parameterisation section.

Pressing the "Down" key selects the corresponding menu item. Pressing the "Enter" key opens the parameterisation level. On this level, the setting value can be changed using the "Up" and "Down" keys. Confirm the settings entered using the "Enter" key. The display returns to the menu item.

Operating elements

5.10 Compressor synchronisation function

The CYCLE STOP menu item is used to select the control system behaviour for the signal at the digital input IN1. By default, IN1 is provided with a jumper. If the jumper is opened, the control program is set to the standby mode. There are two options:

In DIRECT STOP mode the control system is stopped immediately and outputs Y3 and Y4 are not (no longer) controlled. All the time values expired until then will be "frozen" (stored).

In FINISH CYCLE mode the control system will only be stopped after completing the regeneration cycle, and outputs Y3 and Y4 are not (no longer) controlled. All the count values will also be "frozen".

Independent of the type of cycle completion "STB" is indicated for both vessels on the display.

Example: IN1 can be connected to the auxiliary contacts of a compressor. This synchronises the dryer with the compressor. The dryer only regenerates with compressed air being produced. The influencing compressor synchronisation contact does not affect the input valves. The compressor synchronisation contact can also be used as a remote switch and can, for example, be connected to higher-level time or emergency control systems.

5.11 Dew point measurement and energy-saving function

If the internal dew point measuring system is used with a pressure dew point sensor or if an external measuring instrument is used with a 4-20 mA signal output, it must be registered to the control system. For this purpose the option in the PDP SENSOR menu must be set to ON.

The working point of the dryer is specified by the dew point threshold value. It can be set in the PDP SET menu using the arrow keys. The default setting is -40°C *.

Every time the dryer is not operating at the performance limit (i.e. at maximum volume flow rate), a better (lower) pressure dew point value can be achieved than specified by the threshold value set. The dryer then switches to the ECO mode and delays the next vessel change or regeneration phase until the measured dew point value exceeds the threshold value. For information on the total time the dryer was in ECO mode, please use the direct indication method and refer to 3.2.

The dew point alarm is preferably set with a distance of 10° to 20° to the dew point threshold value. This prevents hypersensitive reactions of the alarm messages from occurring. Spontaneous fluctuations of the measured dew point value caused by pressure or load variations within the system are inevitable.

Page 32

Operating elements

Direct activation of the dew point alarm sensor in the event of dew point peaks can also be suppressed by setting a longer delay time. This rule applies: For the entire delay time the measured dew point must be worse than the alarm value set.

5.12 Filters for differential pressure monitoring

The pre- and afterfilters of an adsorption dryer can optionally be provided with differential pressure gauges with an integrated differential pressure monitoring contact. Using the C1 control system the contact signals can be separately evaluated and indicated for the upstream and downstream filters. The connections are provided via switching inputs IN3 and IN4. You can individually switch the alarms on or off and delay their evaluation.

5.13 Overflow monitor

If the pre- and afterfilters are provided with differential pressure monitors (as described in 3.7), the overflow can be evaluated by means of common interrogation of both contacts. It can be assumed that the dryer will be strongly overloaded (internal flow rates too high), if the differential pressure monitors on the upstream and downstream filters are activated simultaneously.

The ALARM-OVERFLOW monitor is switched off by default. The delay time should always be shorter than the delay time of the separate differential pressure monitor on the filters.

Page 33

Operating elements

5.14 Service ticket

The control system program counts the switching cycles of the dryer. This allows for representing the vessel load changes on the one hand and for calculating the actual capacity utilisation or the desiccant and upstream/downstream filter wear using the count values in relation to the duty cycle on the other hand. After reaching a threshold value (66,400 complete load changes (corresponds to approx. 1 year) under normal operating conditions) a service warning message is indicated.

To acknowledge the service warning message a 4-digit numeric code ("service ticket") must be entered. Every time buying service parts and filter elements the customer is provided with a new service ticket including the numeric code. Once a numeric code has been used it cannot be entered again. Upon indication of the next service warning message the control system expects a new code to be entered.

The path for entering the service parameters and monitoring functions can be accessed by entering the password and pressing the "Up" arrow key.

The number of the ticket code is entered digit by digit using the arrow keys. The cursor moves to the next digit by pressing the "Enter" key. When the correct ticket code has been entered TIMER RESET DONE is indicated. When the wrong code

has been entered TIMER RESET FAIL is indicated.

If the ticket code has not been entered correctly, it can be entered again after approximately 2 minutes. If, after this try, the ticket code is not entered correctly again and again, the waiting time for the next try doubles each time until the correct code is entered.

7. Transportation, setting up and storage

7.1 Transportation

DANGER !

– Damage

Damages of the dryer may lead to unpredictable hazardous situations. Operating a damaged dryer may result in serious injury or death. Never start to operate a damaged dryer.

DANGER !

– Risk of tilting

The centre of gravity is in the upper part of the dryer. Tilting of the dryer may result in serious injury or death. During transport and during loading and unloading secure the dryer against tilting using the lifting lugs.

Although great care is taken damages caused by transportation cannot be ruled out. Therefore, always check the dryer for possible damages after transportation and packaging removal. The haulage contractor and the manufacturer or the sales partner must immediately be informed about any damage.

 Make sure to provide adequate lifting equipment when transporting and loading or unloading the

dryer.

 Persons responsible for transportation must be appropriately qualified.  The dryer must only be lifted at the appropriate points using lifting equipment. (Transport pallet;

base frame; support feet; lifting lugs at the top of the vessel) (→ see Figure).

 Take the dryer weight and the maximum allowable load of the lifting and transport equipment used

into account.

 Do not remove the packaging material until the dryer is moved to its final place of installation.  The national regulations for accident prevention must be adhered to.

Page 38

Transportation, setting up and storage

7.2 Setting up

Please refer to section "Description of application" (→ page 9). Here, you will find a list of requirements on the installation site.

Important data of the dryer can be found in section "Technical data" (→ page 12).

Additional requirements on the installation site:

 The ground for dryer installation must be level and capable to carry heavy loads. Ground irregulari-

ties must be levelled in order for tensional forces not to occur in the piping of the dryer. When calculating the total weight, please take the additional load during a hydrostatic pressure test into account. The volume information on the vessel helps when calculating the additional weight.

 Because of noise emissions the installation site should not be in the vicinity of stationary workplac-

es.

 Keep a service distance to walls and other systems around the dryer of 1 m, minimum.  During maintenance of the dryer components lifting equipment with adequate load capacity should

be available and access of this equipment to the dryer must be ensured.

 The place of installation should not be in the vicinity of hallways in order to avoid risks to inexperi-

enced persons.

 Set up the dryer such that the pressure gauge and the control system are clearly visible and can be

operated properly.

We recommend anchoring the dryer into the ground using the holes in the vessel supports.

Page 39

Transportation, setting up and storage

7.3 Storage

To maintain the dryer quality the dryer must be stored at a suitable location and properly prepared for storage.

The place of storage has to fulfil the following requirements:

 Indoors  Protected against weather impact  Frost-free  Dry

If the dryer is to be stored immediately after delivery, it must only be protected against dust using an additional cover.

If the dryer has already been used for drying compressed air, please proceed as follows:

1) Disconnect the compressed air flow from the dryer by closing the valves up- and downstream of

the dryer.

2) Change the setting of the control to „CYCLE MODE – FIX“.(→ Page 31)

3) Operate the dryer for at least 4 more hours without compressed air flowing through the dryer. This

ensures the dryer to be stored with dry vessels. The more regeneration cycles are performed, the dryer the desiccant.

4) Decommission the dryer. (→ Page 49)

5) Depressurise the dryer. (→ Page 50)

6) Disconnect the dryer from the electrical supply. (→ Page 26)

7) Disconnect the dryer from the compressed air system.

8) Close the inlets and outlets of the dryer using flange covers.

9) Place a desiccant bag in the control box.

10) Protect the dryer against dust using a cover.

To recommission the dryer after storage, please proceed as described for initial commissioning. (→ Page 46)

CAUTION !

– Moisture in electrical components

Long-term storage may lead to penetration of moisture into electrical components. This may result in short circuits or damages to these components. Check the electrical dryer components for internal moisture. The necessary actions (insulation resistance test) must only be performed by a qualified electrician.

8. Installation

8.1 Installing the connecting pipelines

DANGER !

– Overload

DANGER !

– Bursting components due to external forces

The dryer components are not designed for externally applied forces and may burst due to additional load impact. Bursting, pressure-bearing components may result in serious injury or death. The support required for the connected pipelines has to be provided by the customer. Transmission of loads or stress into the connection flanges of the dryer is not permissible.

Proper installation is required for safe and error-free operation of the dryer.

Please observe the following steps when installing the compressed air pipeline (4) + (6):

 Make sure that the dryer and the compressed air system are free from pressure. If the compressed

air system has to remain under pressure during installation, the shut-off valves have to be protected against unintentional opening. (2) + (8)

 The compressed air source (e.g. compressor) must be safe-guarded against exceeding of the maxi-

mum allowable operating pressure using safety equipment.

 The compressed air pipelines must be provided with shut-off valves used for disconnecting the dry-

er from the piping system (2) + (8). We recommend using shut-off valves with continuous opening behaviour (e.g. shut-off valves with stem or gear handwheel). This valve behaviour avoids sudden pressure equalisation between the piping sections.

 We recommend using a bypass line (11) around the dryer.  The pipelines must be suitable for use with the maximum possible operating pressure.  The transfer points (threaded of flanged connections) have to be compatible to the dryer inlet and

outlet with regard to nominal width, nominal pressure and type. (→ See general arrangement drawing in the appendix)

 Any vibrations or pulsation must not be transmitted to the dryer via the piping. This may damage

the desiccant, the dryer control system or other components. If required, install compensators or pulsation absorbers in the pipelines to be connected.

DANGER !

– Overpressure

The dryer is under pressure. Suddenly escaping compressed air may result in serious injury. Do not carry out mechanical or electrical work on the dryer as long as the dryer is under pressure.

Page 41

Installation

 Wet pipelines upstream of the dryer (4) should be installed at a slope in order for condensate (wa-

ter and oil) in the line to be discharged in flow direction. If installation of an upright pipeline is inevitable, a condensate drain must be provided at the lowest point of the pipeline. This avoids condensate from being accumulated in the pipeline and suddenly being swept away by the compressed air flow. These kinds of water shocks may damage the filter and dryer and must be avoided.

 Prior to closing the connected pipelines, please check that there are no objects or contaminations

left in the pipelines.

 Remove the end caps from the dryer inlet and outlet.  When checking the installation for leaks the maximum allowable operating pressure of the dryer

must not be exceeded. (→ See specification on the type plate, page 13) Never fill the dryer with water when performing a pressure test. Liquids will destroy the desiccant!

8.2 Installing the power supply

DANGER !

– Electric voltage

The dryer is operated at electric voltages up to 230 V. Touching live parts may result in serious injury or death. Work on electrical components must only be carried out by qualified and authorised personnel. Use a voltage detector to make sure the dryer has been disconnected from the power supply and that there are no live parts before starting maintenance work. In the event of fire, do not extinguish the fire using water.

CAUTION !

– Qualification and experience required

Persons working on and with the dryer have to be qualified personnel who, because of their qualification and experience, are familiar with handling compressed air systems and electrical systems. If you are not experienced in using these systems, please ask the relevant experts for help. We highly recommend that commissioning and maintenance be carried out by the manufacturer or one of the authorised service partners.

DANGER !

– Moisture and contamination in electrical components

Moisture and contamination in electrical components may lead to damages resulting in unpredictable dangers for the operating personnel. As a consequence, short circuits and faulty circuits may occur. Always keep the control box and the terminal box dry and free from contamination and foreign bodies. Make sure the control box and the terminal box are securely closed during operation.

For the data required for connecting and securing the voltage supply, please refer to the wiring diagram (→ see appendix: wiring diagram)

The power supply is connected via a female power connector on the dryer control box (part of the dryer scope):

1) Use a cable that is sufficiently sized for the voltage and power consumption of the dryer when con-

necting the dryer to the power supply. (→ see appendix: wiring diagram)

2) Make sure the power supply is switched OFF and secure it against unintentional reclosing.

3) Pull the female power connector off the male power connector on the control box. (→Page 26)

Qualified electrician required

Electrical connection of the dryer must only be carried out by a qualified electrician who is familiar with reading electro-technical documentation.

Page 43

Installation

4) Remove the mounting screw (1) from the connector

housing (2) first. (The mounting screw serves as locking device for the connector insert (3). The connector insert cannot be removed from the housing of the power connector before the mounting screw has been removed.)

5) Carefully lift the connector insert (3) out of the connect-

or housing using a small screw driver.

6) Lead the cable (8) through the various components of

the cable gland:

(5) gland plug (6) washer (7) rubber seal

Now lead the cable through the gland opening in the connector housing (2).

7) Connect the leads of the cable according to the infor-

mation in the wiring diagram.

8) Put the connector insert (3) back into the connector

housing (2). Put the connector seal (4) back onto the female power connector and tighten the cable gland (5).

The connection of the signal cables is done via the cable glands on the bottom side of the control box:

1) Pull the female power connector off the male power connector on the control box in order to discon-

nect the dryer control from the power supply. (→Page 26)

2) Open the housing of the control box.

3) Individual ports for each IN and OUT signal are available on the circuit board. The allocation of these

CAUTION !

–

Qualification and experience required

9.1 Requirements for initial commissioning

All the requirements for unhindered commissioning must be fulfilled, especially when commissioning is carried out by external qualified personal.

Make sure the following requirements for initial commissioning have been fulfilled:

 External qualified personnel have been informed about the commissioning date in good time (2

weeks in advance, minimum).

 External qualified personnel have been informed about the following in good time: special local

conditions; site-specific safety guidelines; required safety instructions, if necessary; specially required qualifications, if necessary; special personal protective equipment.

 The place of installation can be freely accessed and entered without any risks.  Neighbouring construction sites do not affect commissioning.  The dryer is connected to the compressed air system using pipelines. (→ Page 40)  The dryer is connected electrically and voltage supply is ensured.

(→ Page 42)

 The compressor is ready to operate and personnel for starting and operating the compressor are

present.

 Compressed air can be delivered to the downstream system. A volume flow rate of at least 40% of

the nominal dryer performance can be led through the dryer.

 The dryer is classified pressure equipment (see declaration of conformity in the appendix). Prior to

commissioning the dryer has to be approved by the local authorities according to the applicable national regulations. In the EU, the Pressure Equipment Directive 97/23/EC has to be observed.

Please check the following directly before commissioning:

 The operating limits must not be exceeded. (→ Page 9)  The female power connector is pulled off and the control box is disconnected from the voltage

supply. (→ Page 26)

 The shut-off valves provided by the customer and located upstream and downstream of the dryer

are closed.

 The connections may have become loose due to dryer transportation. Make sure the piping con-

nections, screwed joints and pneumatic lines are tightly secured. Tighten loose connections using the appropriate tools.

Page 46

Commissioning

 Make sure the cable clamps in the control box are tightly secured. Tighten all the screw connections

using the appropriate tools.

 Check all the components for visible damages. If there are defective components, commissioning of

the dryer is not permitted!

DANGER !

– Moisture and contamination in electrical components

9.2 Commissioning the dryer

DANGER !

– Overpressure

The dryer is under pressure. Suddenly escaping compressed air may result in serious injury. Do not carry out mechanical or electrical work on the dryer as long as the dryer is under pressure.

DANGER !

– Electric voltage

The dryer is operated at electric voltages up to 690 V. Touching live parts may result in serious injury or death. Work on electrical components must only be carried out by qualified and authorised personnel. Use a voltage detector to make sure the dryer has been disconnected from the power supply and that there are no live parts before starting maintenance work. In the event of fire, do not extinguish the fire using water.

WARNING !

– Suddenly escaping compressed air (3)

If all conditions required for commissioning are fulfilled, the commissioning procedure can be started. Perform the following steps in the listed order.

Page 47

Commissioning

9.2.1 Pressurisation of the dryer

CAUTION !

– Pressure blows and overload

Rapid opening of the valves may cause pressure blows and increased flow rates in the dryer. Pressure blows and increased flow rates may lead to damages of the dryer. Open the valves very slowly and make sure that the flow noise does not become too loud. Pay special attention when opening valves that can be opened rapidly by means of a pivoting movement.

The dryer valves are controlled by compressed air which is supplied from inside the dryer. For this reason the first requirement for commissioning is reaching a minimum pressure of 4 bar in the dryer. Pressurise the dryer as follows:

1) Make sure the compressed air system upstream of the dryer inlet is under pressure. If necessary,

the compressor must be started.

2) Open the valve upstream of the dryer inlet very slowly until hearing the first clear flow noise. Stop

the procedure when the flow noise becomes loud.

3) Observe the vessel pressure gauges. Pressurisation can be monitored on one of the two pressure

gauges. Make sure the pressure is only rising slowly. Pressurisation speed may not exceed 2 bar/min.

4) Check the system for leaks during pressurisation. In the event of leaks, pressurisation must be

stopped and the leaks must be repaired. To repair the leaks the dryer has to be depressurised again. (→ Page 50)

5) If flow noise and a pressure increase is no longer present when further opening the valve, it can be

opened completely.

9.2.2 Opening the outlet valve

Special attention must be paid if the compressed air system downstream of the dryer is free from pressure.

1) Open the valve downstream of the dryer outlet very slowly until hearing the first clear flow noise.

2) Observe the vessel pressure gauges. Make sure there is no sudden pressure drop in the vessel. The

vessel pressure may not drop for more than 1 bar.

3) If flow noise is no longer present when further opening the valve, it can be opened completely.

4) Air can now freely flow through the dryer. If a volume flow is to be transferred via the dryer, com-

missioning should be performed quickly or the valve downstream of the dryer outlet should be closed again, in order for the dryer not to be overladen with moisture during standstill.

Automatic start

up device

In the event the dryer is frequently started against a pressureless compressed air system, we recommend using an automatic start-up device. (→ Page 24) The automatic start-up device prevents pressure blows and increased flow speeds from occurring even when the compressor is started automatically.

Page 48

Commissioning

9.2.3 Starting the dryer

1) Make sure the dryer is under pressure and that all the valves upstream and downstream of the dry-

er are opened in order for the compressed air to be able to flow through the dryer.

2) Put the female power connector onto the male power connector on the control box. (→Page 26)

Now the display is illuminated and the software version of the control appears on the display for a few seconds. The dryer programs starts up. The start of the program is accompanied by a notable clicking of the solenoid valves.

3) Acknowledge any alarm messages, if required.

4) If any alarm messages are present that cannot be acknowledged, please proceed as described in

section "Error messages and measures". (→ Page 35)

5) If there are no additional alarm messages, the dryer has been commissioned properly.

Monitor dryer operation. The dryer now performs the phases described in section "Function description". (→ Page 20)

Shutting down and restarting the dryer

10. Shutting down and restarting the dryer

10.1 Shutting down the dryer in case of emergency

1) Disconnect the power supply to the dryer. (e.g. by pulling the power connector off the control box.

(→ Page 26)

2) Close the valves upstream and downstream of the dryer.

3) The dryer has now been shut down.

10.2 Stopping the dryer

The dryer can be stopped by ...

1) Disconnecting the power supply.

2) Pulling the power connector off the control box.

3) Opening the “compressor contact”. . (→Page 31)

Compressed air must no longer flow through the dryer. Otherwise, it is overladen with moisture.

Please note that the dew point becomes worse after a certain standstill period. Worsening of the dew point is not a dryer error but is caused by external moisture slowly penetrating the static volume in the piping. As soon as the compressed air flows again, the dew point will also become better again

10.3 Shutting down the dryer

1) Stop the dryer as described in the above section.

2) Pull the power connector off the control box.

3) Close the valves upstream and downstream of the dryer.

4) The dryer has now been shut down.

5) Prior to working on the dryer it has to be depressurised.

Page 50

Shutting down and restarting the dryer

10.4 Depressurising the dryer

WARNING !

– Exhausting pressure

Compressed air exhausting to the outside is very loud and may carry small particles. This may cause hearing damage as well as injuries of the eyes and of the skin. Close the openings used for releasing the pressure by means of a silencer suitable for the pressure. Open the valves for releasing the pressure only very slowly. Always wear eye and hearing protectors when working in the vicinity of the dryer.

1) Close the valves upstream and downstream of the dryer.

2) Open the valve on the after-filter (→ Page 40)

3) Monitor the pressure on the pressure gauges of the dryer.

4) Wait until the pressure has dropped to 0 bar on both pressure gauges.

10.5 Restarting the dryer

Please proceed as described in chapter "Commissioning". (→ Page 46) If the relevant requirements have already been fulfilled, the corresponding steps of the chapter can be skipped.

Page 53

Maintenance and repair

11.1.2 Cleaning the dryer and dryer control

Make sure the surroundings are clean and tidy.

1) Clean the dryer surface using a slightly moist cloth. Do not use detergents containing acids or sol-

vents.

2) Make sure the operating elements and the type plates can always be clearly read.

3) Keep water and metallic dust away from the electrical components.

11.1.3 Determining the residual oil content in the compressed air

The adsorber is equipped with an oil indicator. The oil indicator (QI) is used to periodically measure the residual oil content on the outlet side of the adsorber. The measurement can be performed by the operator in regular intervals.

1 Indicator tube (QI) with scale division (0 bis 2,0)

2 Threaded joint to fix the indicator tube with 3x O-ring

3 Needle valve (HV1)

4 Pressure reducer (PC) reduces the operation pressure to 7 bar measuring pres-

sure

5 Vessel connection

The measuring principle is as follows: For the duration of the measurement, the needle valve (3) is opened so that a pressure-reduced partial flow of purified compressed air is fed through the indicator tube (1). The indicator tube is secured by means of a union nut (2). Any residual oil contained in the air leads to a change of colour of the scale segments of the tube, whereby a higher concentration leads to more segments being coloured. The change of colour is irreversible; after completion of the measurement, the indicator tube must thus be replaced To measure the residual oil concentration, proceed as described below. A template of the measuring log used for this procedure is included in the appendix.

WARNING !

– Risk of loose indicator tube

Risk of damage to eyes! If not properly secured, the indicator tube might be propelled out of its holder. Prior to opening the needle valve, check that the union nut at the indicator tube is properly tightened. When working at the oil indicator, always wear protective goggles.

1) Prepare measuring log and hold it ready.

2) Check union nut holding the indicator tube and retighten, if necessary.

3) At the indicator tube, mark the highest segment with a colour change, using a suitable pen.

4) Open needle valve by turning its handle anticlockwise. Write down start date and time of the

measurement..

5) Leave needle valve open for the desired duration of measurement (e.g. 5 hours)..

6) Subsequently, close the needle valve. Write down end time of measurement.

Page 54

Maintenance and repair

7) At the indicator tube, mark the highest segment with a colour change, using a suitable pen. Write

down the number of scale segments that have changed colour since the start of the measurement.

8) Determine the concentration in the above table, based on the duration of the measurement and

the number of scale segments with colour

9) Write down the residual oil concentration in ppm, parts per million] in the measuring log.

10) To determine the residual oil content in [mg/m3], multiply the above value by a factor 1.2. Write

down this value in the measuring log.

Example: Duration of measurement = 25 h No. of scale segment with colour change = 0,3 ( = approx 7mm) Operating pressure during measurement = 8,5 bar (ü)

It follows ...  table 1. is to use !

admissible residual oil concentration

for 0,2 scale change  0,09 ppm for 0,4 scale change  0,18 ppm for 0,3 scale change  (0,09 +0,18)/2 = 0,135 ppm residual oil content in g/m³  0,135 x 1,2 = 0,162 mg/m³

1) Choose a measuring interval (e.g. 4 weeks) and a duration of measurement (e.g. 4 hours)

2) To establish the remaining capacity of the purifying agent, you must carry out measurements of the

same duration at fixed intervals

3) Record the development of residual oil content over the time.

4) If the residual oil begins to rise more rapidly, the granulate is exhausted and must be replaced.

11.1.4 Replacing indicator tube

If all scale segments in the indicator tube show a colour change, the indicator tube is spent and must be replaced.

WARNING !

– Risk of loose indicator tube

1) Ensure that the needle valve (3) is closed and that the indicator tube (2) is not under pressure. To

close the needle valve, turn its handle clockwise.

2) Loosen the reducer (2) below the union nut, using an appropriate tool. Fix locknut with a second

roller wrench so that the needle valve (3) is not turning.

3) Exchanging the old indicator tubes against a new indicator tube. Pull the three O-rings on the new

indicator tube, so that stands out approx. 10 mm of lower pipe end from the O-rings

4) Check the union nut and the reducer below (2) to ensure that they are properly tightened, and new

indicator tube is properly fixed. Open the needle valve (3) for a short time and check screw connections for tightness.

11.1.5 Checking if cable and terminals are securely fixed

The cable connections may be loosened due to transportation or vibrations. To prevent malfunctions from occurring, all the cable connections must be checked to ensure that they are securely fixed. In the event of

Page 55

Maintenance and repair

heavy vibrations, inspection must be carried out more frequently. The necessary actions must only be performed by a qualified electrician.

1) Decommission the dryer. (→ Page 49)

2) Depressurise the dryer. (→ Page 50)

3) Disconnect the electrical power supply from the dryer and protect it against unintentional recon-

nection.

4) Make sure the cables and terminals are securely fixed by tightening them, if required.

Only use tools approved for electrical work.

5) Replace any damaged or corroded components.

6) After the control box has been reclosed, the dryer can be recommissioned again.

11.1.6 Calibrating the dew point sensor

The dew point sensor (MT01) is subject to ageing which leads to inaccurate measurements over time. Oil vapour and other contamination may render the sensor unusable over time. To prevent operating errors from occurring the dew point sensor must be calibrated regularly.

1) Decommission the dryer. (→ Page 49)

2) Depressurise the dryer. (→ Page 50)

3) Loosen the screw at the sensor cable socket and remove the cable socket. The cable socket is

kept at the dryer and will be reused.

4) Unscrew the sensor from the measuring socket using an appropriate wrench. Only hold the

sensor at the hexagon of the sensor housing!

5) Insert a calibrated sensor of the same type in the measuring socket.

6) Plug the cable socket onto the calibrated sensor and tighten the cable socket.

7) Pressurise the dryer and commission the dryer again. (→ Page 49)

11.1.7 Replacing filter elements

The filter elements in the filters prevent particles and aerosols in the compressed air flow from entering the system. The filter elements in the filters will be clogged over time and thus the compressed air flow is throttled. To prevent operating errors from occurring, the filter elements have to be replaced regularly. Check the differential pressure gauge at the filter (if available). When exceeding approximately 350 mbar, the elements should be replaced. Replacement is due after one year at the latest.

Delicate dew point sensor

The dew point sensor contains a very delicate electronic system. Vibrations and shocks may lead to sensor damage. Handle the sensor with particular care.

Replacement program

The manufacturer provides a replacement program for old dew point sensors.

1) Order a new dew point sensor.

2) Exchange the sensors upon receipt of the new sensor.

3) Send the old sensor back to the manufacturer. For this purpose, use the protective packaging

of the new sensor. Only sensors that are undamaged can be recalibrated!

4) After receipt of the old, undamaged sensor the price difference of the new sensor and cali-

bration will be credited. The old sensor remains at the manufacturer.

Page 56

Maintenance and repair

1) Depressurise the filter. (→Page 50)

2) For filter replacement please proceed as described in the operating manual of the filter.

11.1.8 Replacing the expansion silencer

The expansion silencer (X1) is contaminated by dust and condensate over time and thus the expansion air flow is throttled. To prevent operating errors from occurring, the expansion silencer has to be replaced regularly.

1) Decommission the dryer. (→ Page 49)

2) Depressurise the dryer. (→ Page 50)

3) Unscrew the old expansion silencer (X1)

from the connecting part using your hands

or an appropriate tool.

4) Screw the new expansion silencer (X1) into

the connecting part and tighten it using your

hands or an appropriate tool and some seal-

ing tape.

5) Pressurise the dryer and commission the dryer again. (→ Page 49)

11.1.9 Replacing the sealing set of the valves (V1-4) and the check valves (RV1-2)

The valves and check valves are subject to ware. The seals must be replaced in regular intervals. Spare part kits containing all parts required for proper maintenance can be purchased from the manufacturer or one of his service partners

11.1.10 Checking and replacing the granulate / Cleaning the strainer basket

WARNING !

– Risk of slipping

CAUTION !

–

Granulate dust (desiccant or activated charcoal)

Using the granulate may lead to mineral or organic dust formation. Desiccant dust may cause eye and respiratory tract irritations. Wear eye protection and a dust mask when handling the granulate.

WARNING !

– Risk of falls

Page 57

Maintenance and repair

The desiccant is subject to ageing and its drying performance is reduced over time. The service life of the desiccant depends on numerous operating parameters and cannot be exactly predicted. The service life is approximately 3 to 5 years. Under very favourable conditions (e.g. oil-free compressed air) the service life may be considerably longer. The quality of the desiccant can be assessed quite well when monitoring the operating phases. If the adsorption phase is reduced significantly during operation in the „CYCLE MODE - VAR“ mode, the desiccant should be replaced. Desiccant replacement is generally useful as a preventive maintenance measure in conjunction with other repair work. (See advisory note below)

Activated charcoal is a consumable. It is exchanged when it is saturated with oil. As a precautionary measure we recommend to exchange it every year..

Desiccant replacement is part of a large inspection run. At the same time, other maintenance activities should be carried out. (See maintenance table → page 51)

1) Decommission the dryer. (→ Page 49)

2) Depressurise the dryer. (→ Page 50)

3) Remove the upper check valve block. (RV1, RV2)

4) Remove the strainer basket (SB1, SB2) and clean it

from desiccant residues.

5) Remove the sealing material and clean the threads

surfaces from residues of the sealing material..

6) Provide an adequately sized container for the used desiccant.

7) Remove the used desiccant from the vessel using a suction device (e.g. vacuum cleaner).

8) Provide an adequately sized container for the used desiccant.

9) Remove the used desiccant from the vessel using a suction device (e.g. vacuum cleaner).Reinigen

Sie den Stutzen der Trockenmittelentleerung und verschließen Sie den Stutzen wieder unter Verwendung geeigneter Dichtmittel.

10) Remove the used desiccant from the construction site.

11) Provide the new desiccant *. Make sure to use two different desiccant types which create two sep-

arate layers in the vessel. Distribute the different desiccant types equally to the two vessels. In the event you are unsure which desiccant to fill in first, please contact the manufacturer.

CAUTION !

– the activated charcoal is combustible

Page 58

Maintenance and repair

12) Fill the vessel with the different types of

granules as shown in the picture. The pic-

ture shows the typical vessel filling for

compressed air drying. Other applications

might use different types of desiccant.

(e.g. CO2-removal or other technical gas-

es.)

13) Fill up the vessel almost to its full extent.

Make sure that the strainer basket (SB1,

SB2) can still be inserted in the vessel

opening by slightly pressing on it. During

operation the desiccant will be com-

pressed to some extent and the desiccant

volume will be slightly reduced

14) Reinsert the strainer basket (SB1, SB2) in-

to the vessel using new sealing material

(e.g. Teflon tape).

15) Place the upper check valve block back

onto the vessels (A1,A2) and close the

elbow connector.

16) Clean the floor thoroughly from desiccant

residues.

17) Slowly pressurise the dryer again. (→ Page 47) Carry out a leak test using a leak detection spray. In

the event of leaks the dryer will have to be depressurised prior to repairing the leaks.

(* = Different applications require different desiccant fillings. Even a filling with only one type of desiccant is possible and common. Please investigate for the correct type and quantity of desiccant before you order the replacement desiccant. The manufacturer holds records of the desiccant filling used for each individual dryer(→ Page 5). Please state the dryer serial number in your correspondence. (→ Page Fehler! Textmarke nicht definiert.))

Please note that, directly after desiccant replacement, the dew point may become worse. The new desiccant will reach the full drying performance only after a longer operation period. For the time directly after desiccant replacement it may be useful to select a dew point limit value as described in the "Properly selecting the dew point limit value" advisory note. (→ Page 9)

Filling of dryer vessels: MS = molecular sieve

WS = silicagel, waterproof Filling of third vessel: A = activated charcoal

Taking the inspection intervals for the vessels into account

A routine inspection is required for the pressure vessels. In Germany, according to AD 2000 Code a

routine inspection has to be carried out every 5 years by a notified body.

Please note that different national regulations may apply in other countries. We recommend replacing the desiccant in the course of this inspection run at the latest. Combine desiccant replacement and vessel inspection. The manufacturer provides desiccant replacement in conjunction with "measures parallel to approval".

Page 59

Maintenance and repair

Increased dust contents after desiccant replacement

Filling the new desiccant in the dryer results in increased dust contents in the vessels. In the first weeks after recommissioning the dust is forwarded to the downstream filter and the filter elements will deteriorate faster than during later operation. We therefore recommend to recommission the dryer using the old filter elements and to use the new filter elements and the new expansion silencer only after some weeks.

Granulate (desiccant and activated charcoal)

Disposal

Dispose of the desiccant according to the local regulations.

Waste codes according to the Waste Catalogue Ordinance:

 Non-contaminated desiccant: 06 08 99  Contaminated activated charcaol: 06 13 02  Contaminated desiccant: The waste code will have to be determined by the waste producer

taking the type of contamination into consideration. The desiccant must be disposed of in an appropriate disposal plant.
