1. SAFETY AND SYSTEM PRECAUTIONS
1.1 Definition of the Safety Symbols
1 Only experienced and trained personnel familiar with all of the relevant laws, rules and regulations, capable to perform the needed activities and to
identify and avoid possible dangerous situations while handling, installing, using and servicing the machine.
1.2 Operational Warnings
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 3
The packaging materials are recyclable. Each material must be properly disposed in a manner complying with the rules and regulations of the local municipality government.
The purpose of the machine is the separation of water vapor that is present in compressed air. It is not intended to separate oil or other contaminants that are present in compressed air. The dried compressed air output from this dryer cannot be used for respiration purposes of any kind.
Serious consideration should be given when selecting the installation site for the dryer, as an improper location could directly affect the proper operation of the dryer.
This unit is not suitable to be used in explosive atmospheres, where risk of fire could exist, in the presence of gaseous or solid pollutants or in outdoor applications or areas exposed to the elements.
Do not use water to extinguish fire on the dryer or in the surrounding area.
Machine level noise could be higher than 85 dBA. Install the unit in a dedicated area where people are not normally present. The installer and/or end user is responsible for the correct installation of the dryer in order to prevent excessive noise exposure in the work environment. The installer and/or end user is responsible to install proper safety signs at the installation site.
2. INSPECTION AND INSTALLATION
2.1 Incoming Inspection and Transportation
All dryers are tested and inspected at the factory prior to shipping. Thoroughly inspect and verify the integrity of the packaging upon receipt and note any damage on the freight bill. Place the unit as close as possible to the installation point before unpacking the contents and inspect for concealed damage. Freight claims are to be filed with the carrier immediately and the manufacturer’s technical service department notified thereafter.
To move the packaged unit, we suggest the use of a suitable crane or forklift. We do not recommend moving the
unit by any hand operated or manual mechanism.
Handle with care. Heavy blows could cause irreparable damage. Even when packaged, keep the machine protected from severe weather.
2.2 Design and Use of the Dryer
This dryer has been designed, manufactured and tested to be used only to separate the humidity normally contained in compressed air, any other use is considered to be improper. The manufacturer is not responsible for any problems arising from the improper use of this machine.
The end user, in any and all cases, is responsible for any resulting damages.
Moreover, the correct use of this machine requires the verification of certain installation conditions, in particular:
Voltage and frequency of the electrical power supplied Pressure, temperature, flow rate and chemical composition of the incoming compressed air Ambient temperatures
The dryer is supplied as tested and fully assembled. The only operation left for the end user is the connection to the plant and adjustment of the purge rate in compliance with the instructions given in this manual. Factory settings are at nominal conditions at 100 psig and the stated model flow rate (see page 5).
2.3 Location and Installation
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 4
Technicians that service the machine must wear hearing and eye protection while servicing the dryer. Each employee must select a proper personal protection device (PPD) hearing protector such as earmuffs, ear canal caps or earplugs in order to prevent permanent hearing damage or loss.
Incorrect installation may void warranty.
1. Inlet piping including an isolation valve
2. Outlet piping including an isolation valve
3. Coalescing pre-filter and particulate post-filter
We recommend the dryer be installed with a 0.01 micron iPUR coalescing pre-filter at the inlet and a 1.0 micron iPUR particulate post-filter at the outlet. It is recommended to install both 5.0 micron and
1.0 micron filters upstream of the dryer in order to maintain the operational lifespan of the inlet filter to the dryer. In addition, we recommend the use of a iMAT zero air loss drain on the pre-filter and at all other condensate collection points, especially those upstream of the dryer.
4. IMPORTANT! Bypass piping is necessary. Only bubble tight valves should be used.
5. Make the required electrical connections; please refer the type plate of your dryer. The end user is
responsible for providing short circuit protection for the dryer.
6. Points of access should be provided upstream and downstream of the dryer for periodic monitoring of
dew point, pressure and temperature prior to finalizing the installation. Taking periodic dew point measurements just downstream of the dryer gives the best indication of whether the dryer is performing optimally. We recommend using METPOINT® instrumentation to ensure accurate measurements.
7. All piping must be adequately supported and at least of equal size to the dryer connections.
Minimum Installation Requirements:
Select a clean, dry room that is free of dust and protected from atmospheric disturbances. The location must be smooth, horizontally level, able to bear the weight of the dryer and vibration free Minimum ambient temperature of +40 °F Maximum ambient temperature of +120 °F Allow a clearance of at least 3’ on all sides of the dryer in order easily facilitate all maintenance needs The dryer is not required to be anchored to the supporting surface Coalescing pre-filter with drain must be installed The location of an air receiver tank will vary depending on compressor type and application conditions
NOTE: All piping and electrical connections should be inspected prior to installation to ensure they have maintained their integrity during shipping and locating the dryer.
First, make the initial connections as follows:
Locate the coalescing pre-filter as close to the dryer as possible while still maintaining sufficient space for routine maintenance and service. Inlet air entering the dryer must pass through a coalescing pre-filter in order remove entrained condensate and oil to prevent fouling of the desiccant and maintain standard operation. Any liquid condensate entering the desiccant bed will lead to overloading of the dryer, poor dew point performance and rapid deterioration of the desiccant material. Any oil entering the desiccant bed may permanently reduce the capacity of the desiccant material.
Desiccant dust traveling downstream of the dryer may cause contamination and/or accelerated wear to other components and equipment. Therefore, a particulate post-filter should be provided to prevent desiccant dust from traveling downstream. Activated alumina is considered a nuisance dust and proper precautions should be taken when handling desiccant (refer to applicable MSDS sheet).
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 5
Before any attempt is made to operate the dryer, the operator must thoroughly read and understand this installation and operation manual.

We recommend the dryer be installed with a 0.01 micron iPUR coalescing pre-filter at the inlet and a 1 micron iPUR particulate post-filter at the outlet. It is recommended to install both 5 micron and 1 micron filters upstream of the dryer in order to maintain the operational lifespan of the inlet filter.
Optimal installation is with moderately sized receivers at the inlet and outlet side of the dryer. This allows for the
additional free cooling and moisture collection and more consistent dryer inlet flow provided by an upstream receiver, while providing the most reliable shop air supply due to the downstream receiver.
Under no circumstances should the peak demand air flow exceed the maximum rated air flow of the dryer.
2.4 Mounted Filters with Bypass
Mounted Filters with Bypass is an optional setup for the heatless regenerative dryer. The three valve system bypass allows for the flow of air to be uniterupted while servicing or completing preventative maintinance such as:
Exchange pre- and post- filters Services exhaust sIlencers Change desiccant

3.3 General Function
The iDRY iDHLBe heatless desiccant dyer series are fitted with two pressure vessels, positioned parallel to one another and filled with adsorption material (⅛” activated alumina as standard). While the compressed air is dried in one tower, the saturated desiccant is regenerated in the second. A minimal portion of the treated air is used for the regeneration process and expelled along with the condensate, through the silencers.
The saturated inlet air is cycled through each of the two desiccant beds in an alternating sequence where one bed is on­line at full line pressure and flow, adsorbing the water vapor. This is the drying bed.
The other bed is then considered to be in an off-line state at atmospheric pressure and is being regenerated by a depressurized portion of the dried, treated outlet air (purge air). This is the regenerating bed.
The purge air is routed from the dry outlet air through the purge flow control valve, desiccant bed, purge exhaust valve and finally exhausted to atmosphere through silencers to finish the regeneration process. Purge air consumption is generally the highest cost involved with operating a heatless adsorption dryer and is non-recoverable. Therefore, the air system where the dryer is installed must account for this usage (approximately 15% of the inlet air flow).
Just before the freshly regenerated bed is brought to an on-line state to become the drying bed, it is slowly pressurized from atmospheric pressure up to line pressure. This is the re-pressurization step that prevents desiccant bed fluidization (bed lifting) and dusting. The desiccant beds will now switch functions where the fresh desiccant bed is now drying and the saturated bed is now regenerating.
This cycle will continue automatically unless the dryer is shut down.
All desiccant dryers work using the principle of adsorption, which is the process by which water vapor is removed from the compressed air being dried. All desiccant material types are adversely affected by oil, aerosols, dirt, rust, scale and

liquid water. If contaminated the desiccant material will lose its adsorption proprieties. Moreover during operation, the desiccant releases solid particles (as fine powder) that are particularly abrasive and can be extremely damaging to downstream components and users.
For this reason, it is highly recommended that the dryer is equipped with two high-efficiency iPUR filters:
0.01 micron filtration grade coalescing pre-filter with differential pressure gauge and either a float drain or iMAT 1.0 micron filtration grade particulate post-filter (differential gauge optional) and with a manual drain.

3.5 Cycle Operation
Pressurization Sequence
After proper pressurization of the unit the dryer the operator may begin the start-up. During the start-up phase, both purge exhaust valves PVA and PVB (5 and 6) are closed for a period of 70-seconds to help guarantee the complete pressurization of the dryer.
Step 1-2 The purge exhaust valve PV-B (2) is powered open to depressurize vessel for regeneration.
Simultaneously the solenoid valve IV-B (1) is powered closed by the pneumatic tower selection. The compressed air flow is directed to vessel A, where the desiccant material adsorbs the humidity down to the target dew point. Through the purge control valve (6) a defined amount of dry air coming out from tower A is expanded into vessel B. This dry air while crossing vessel B, dries the adsorbent material dragging away the humidity through the PV-B valve (2) and exits the silencers (3). At the end of this stage the adsorption material of vessel B is completely regenerated.
Step 3 The purge exhaust valve PV-B (2) is closed and then through the Purge Control Valve (6) vessel B is re-
pressurized to the working pressure. The sum of steps 1-2 + 3 equals a half cycle time.
Step 4-5 The purge exhaust valve PV-A (2) is powered open to depressurize vessel for regeneration.
Simultaneously the solenoid valve IV-B (1) is powered closed. The compressed air flow is directed to vessel B, where the desiccant material adsorbs the humidity down to the target dew point. Through the purge control valve (6) a defined amount of dry air coming out from tower A is expanded into vessel B. This dry air while crossing vessel A, dries the adsorbent material dragging away the humidity through the PV-A valve (2) and the silencers (3). At the end of this stage the adsorption material of vessel A is completely regenerated.
Step 6 The purge exhaust valve PV-A (8) is closed and then through the Purge Control Valve (6) vessel A is re-
pressurized up to the working pressure. The sum of step 4-5 + 6 equals a half cycle time. At the end, the cycle starts up again from step 1-2.
NOTE: The cycles are symmetrical therefore 1-2=4-5 and 3=6

4. PURGE VALVE ADJUSTMENT
The purge flow control valve must be set to match the inlet pressure of the dryer. The valve must be opened to the corresponding number of turns referenced in the table below.
Always base the pressure adjustment on the lowest operating pressure of the system The initial setting from factory is for 100 psig operation
The procedure for adjusting the purge flow control valve is as follows:
The knob stem of the valve is numbered and a complete turn is considered turning the control knob 360° from number to number. The number of turns expressed in the table below is based on the number of turns from the closed position.
1. Loosen the screw using a flathead screwdriver or allen-head
2. Turn the purge flow control valve clockwise until the stopping point – the valve is now closed
3. Turn the purge flow control valve counter clockwise until the setting for the desired operating pressure value is
reached – the valve is now open
4. Tighten the screw using a flathead screwdriver or allen-head
Purge Adjustment Table
Consult a factory representative for more information.
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 11
Verify that the operating parameters match with the acceptable ranges indicated on the data plate of the dryer (voltage, frequency, air pressure, air temperature, ambient temperature, etc.). This is not the same as the ASME UW plate on the vessels and may be lower than what is stamped on the ASME UW plate.
The start-up must be performed by qualified personnel only. It is mandatory that the qualified person in charge will verify safe operational conditions complying with the local safety and accident prevention requirements.
The same qualified person will be responsible for the proper and safe operation of the dryer. Never operate the dryer if all panels are not properly in place or if any componentry is missing or appears damaged.
Service to be performed by qualified personnel only. The end user is responsible to ensure that the dryer will never be operated with pressure that exceeds the maximum pressure rating of the unit. Operating the dryer at a pressure higher than the maximum rating could be dangerous for both the operator and the machine.
The connection to the main power is to be carried out by qualified personnel, and the safety protocol must comply with local rules and laws.
It is mandatory to ensure the connection to the ground terminal.
The condensate is discharged at the same pressure as the air entering the dryer. Never point the condensate drain discharge towards anybody.
DO NOT DISPOSE OF CONDENSATE INTO THE ENVIRONMENT The condensate collected in the dryer contains oil particles released into the air stream by the compressor. Dispose of the condensate in a manner compliant with all local, state and Federal rules and regulations. We highly recommend the installation of either a QWIK-PURE® or ÖWAMAT® oil-water separator at the final collection point for all condensate discharge lines within the facility (i.e. from the main header).
5. START-UP
5.1 Verification Prior to Start-up
Before delivery, each dryer is submitted to accurate tests simulating real operating conditions. Nevertheless, the unit could be damaged during transportation. Therefore, we suggest checking the integrity of the dryer upon arrival (see page 4) and observing the dryer during the first hours of operation.
The inlet air temperature and air flow rate entering the dryer must be within the limits indicated on the data plate.
Installation precautions must be taken in order to limit the vibration that can occur during the operation of the dryer. Therefore, we recommend using flexible connecting pipes that are able to insulate the dryer from possible vibrations originating from the pipe line.
Before connecting the unit to the electric power, verify that the voltage and the frequency available on the mains correspond to the data on the data plate of the dryer. In terms of voltage, a 5% tolerance is acceptable. The wire size feeding the dryer must comply with the consumption of the dryer, while keeping into account also the ambient temperature, the conditions of the main power junction box, the length of the wire, and the requirements enforced by the National Electric Code.
Connect and properly fasten the condensate drain to a collection system or container. The outlet condensate hose cannot be connected to pressurized systems.
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 12
During the first start-up or start-up after a long period of inactivity or following maintenance, the technician must comply with the instructions below. The start-up must be performed by qualified personnel only.
The employee that operates the machine must wear hearing and eye protection before operating the dryer. Each employee must select a proper personal protection device (PPD) hearing protector such as earmuffs, ear canal caps or earplugs in order to prevent permanent hearing damage or loss.
1. With the dryer bypassed and in isolation (see page 14)
2. SLOWLY open the inlet isolation valve allowing compressed air into the dryer. It is critical that the dryer
be pressurized slowly to prevent fluidization of the desiccant bed. Keep the outlet isolation valve closed at this time.
3. SLOWLY open the outlet isolation valve. All valves are now in their open positions and compressed air is
flowing through both towers and downstream.
4. Close the dryer bypass valve. The bypass valve must be bubble tight to prevent any moisture from
contaminating the dry air outlet from the dryer.
5. Plug in the dryer and energize the electrical circuit – the dryer is now ON.
6. Verify that the controller is on.
7. Check all piping for compressed air leaks.
8. Test the condensate drain on the pre-filter.
9. After 1-minutes from start-up the adsorption tower B will be depressurized.
10. Wait for the dryer to make 10 full cycles (i.e. the depressurization from tower A to tower B).
11. The dryer will make the first 5 cycles short cycles, running at 50% run time without regard for dew point.
12. The pressure swing cycles occurs, every 5 minutes (outlet dew point of -40°F).
5.2 Start-up Procedures
Start-up Sequence
Please read and understand the entire manual before operating the dryer Verify the factory settings Verify the wiring diagrams that pertain to your unit and ensure the correct power supply is connected
Do not energize the circuit at this time
Verify that proper short circuit protection has been provided following all applicable codes and regulations Verify that all the steps of in the previous chapters relating to installation have been observed Verify that the connection to the compressed air system is correct Verify that the condensate drain pipe is properly fastened and connected to a collection system or container Remove any packaging and other material that might obstruct the area around the dryer
Before starting the dryer your compressor should be running, your compressed air system pressurized and the dryer bypassed and not yet pressurized.
NOTE: During the first days in operation, the dew point cannot be guaranteed because the adsorption material can contain humidity from storage. At the first start-up or start-up after a long inactivity period or following maintenance shutdowns, we recommend operating the dryer at a reduced nominal flow of 50% during the first two days.
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 13
Users operating the machine must wear hearing and eye protection. Each employee must select a proper personal protection device (PPD) hearing protector such as earmuffs, ear canal caps or earplugs in order to prevent permanent hearing damage or loss.
Isolation
1. Allow the dryer to reach its re-pressurization step and fully re-pressurize.
2. Once fully re-pressurized, remove power from the dryer.
3. Open the bypass valve.
4. Close the outlet isolation valve.
5. Close the inlet isolation valve.
Depressurization and Shut Down
1. Open the bypass valve.
2. Close the outlet isolation valve.
3. Close the inlet isolation valve.
4. Allow the dryer to continue to run. During the normal operating cycle both towers will blow down and
depressurize.
5. Disconnect the power to the dryer.
6. Open the manual ball valves on any filters with manual ball valves to allow full depressurization. Also,
leave manual ball valves on filter open during maintenance and service.
IMPORTANT! Always remove all pressure and disconnect all power before servicing the dryer.
To restart the dryer, follow the start-up procedure in Section 5. START-UP
5.3 General Operation
The dryer may require up to 48-hours of operation to reach normal operating outlet dew point. Therefore,
indicators and alarms do not need to be recognized during this time. Applications where a dew point lower than
-40 °F is needed, may require additional time to reach equilibrium.
The dryer will not perform without properly sized and installed pre-filtration, condensate drainage and correct
purge flow adjustment.
After the initial start-up some dusting may occur. This is normal and will diminish with time, although may
accelerate the first maintenance interval of the exhaust valves, exhaust silencers and post-filter element.
Exhaust valves and silencers may have to be cleaned due to dusting from shipping and the initial start-up, and
should be cleaned regularly to ensure proper operation. Post-filter elements should also be part of a regular preventative maintenance schedule.
Never service the dryer or filters without first relieving pressure from the dryer. A desiccant dryer should never be pressurized or depressurized suddenly. This will cause degradation and
dusting of the desiccant bed.
The dryer is designed for a maximum operating pressure of 150 psig as standard.
6. ISOLATION AND SHUT DOWN PROCEDURES
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 14
7. CONTROLLER INFORMATION AND OPERATION
7.1 Display Overview
The LED illuminated PID controller interfaces between the dryer and the operator (shown above). The following pages the detailed information about the controller’s settings and operation.
The controller has a total of nine LEDs to inform the operator its step in operation:
Two check valves indicating the direction of air flow out of the dryer One purge valve indicator used during regeneration Two LEDs are used to indicate the active dryer tower during operation Four LEDs indicate purge exhaust valve and inlet valve PV- and IV-
The controller has two additional LEDs used to indicate power and service in the upper left corner of the display as shown by the corresponding icons. During normal operation, the power LED is green and the service indicator LED is off.
7.2 Controller Startup
It is important to note that the controller is programed to run five times in succession for a short cycle. That is a 50% shorter run times without consideration of the dew point input to bring the dryer to a defined state. After this startup procedure the device is in normal operation mode.
During startup the compressor synchronization input is also active.
7.3 Controller Inputs
The controller and housing provide three M12 and two M16 glands on for its input / output connection lines. For input, the connections are:
Power cable Compressor-synchronization signal
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 15
The input “compressor synchronization”, is meant to synchronize the dryer with switching ON and OFF of the compressor. Hence, it prevents a situation where the dryer continues to operate and use rinsing air from the compressed air network though there is no supply of compressed air. In case the voltage (120V AC-Input) drops at the input, all valves are immediately closed.
After the compressor signal comes back online, the drying cycle is continued from the same point, meaning that the last open valve also opens again. Note two exceptions:
This is not valid if the remaining regeneration time is less than
30 seconds, in which case it immediately switches over to the other drying column, which means the other valve is opened.
If the compressor is switched off for more than 24 hours, then
the device is started with five short full Nema cycles as though the operating voltage has been interrupted (i.e. as after RESET).
7.4 Controller Outputs
The controller outputs information two ways, one, to the controller display, the other, to the dryer system through the housing glands:
Purge Exhaust Valve A Purge Exhaust Valve B
The controller outputs the dryer’s operational step to the controller display LED indicators. This indicates the activated valves and drying tower. In addition, the power light and service indicator are displayed.
The controller outputs an electrical signal to the tower selector solenoid valve and energizes the appropriate valves based on dryer’s step of operation.
7.5 Controller Settings
The controller unit has a total of eight DIP switches with the following parameters:
Three DIP switches are used to set the tower regeneration time Two DIP switches are used to set the pressure build-up time One DIP switch used for future expansion One DIP switch aligns the controller with the compressor sync One DIP switch used for future expansion
Below is a picture of the DIP switch control interface:
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 16
The controller’s eight DIP switches are detailed in the following section. These switches are adjustable but should only be done so by a qualified person.
7.5.1 Regeneration Time (1, 2, 3)
The regeneration time is the time selected for steps 1-2 detailed in Section 3.5. The three DIP switches can be adjusted to eight (8) selection times between 2.5 and 6 minutes in increments of 30-seconds as follows:
000 2.5 minutes 100 3.0 minutes 010 3.5 minutes 110 4.0 minutes (factory setting) 001 4.5 minutes 101 5.0 minutes 011 5.5 minutes 111 6.0 minutes
7.5.2 Re-Pressure Build-Up Time (4, 5)
The re-pressure build-up time is the time selected for step 3 in Section 3.5. The two DIP switches can be adjusted to four (4) regeneration times between 60 and 120 seconds in 20-second increments as follows:
00 60 seconds (factory setting) 10 80 seconds 01 100 seconds 11 120 seconds
7.5.3 Expansion (6)
This DIP switch is not currently in use and should be set to OFF, ‘0’.
7.5.4 Compressor Sync (7)
The compressor sync to the controller is detailed in section 7.3. It can be set wither to an ‘ON’ or ‘OFF’ position.
0 OFF - compressor is synched 1 ON - compressor is NOT synched (factory setting)
7.5.6 Expansion (8)
This DIP switch is not currently in use and should be set to OFF, ‘0’.
7.5.7 Factory Default Settings
The factory default settings of the DIP switches are as follows:
Purge Air Time 4.0 minutes (1, 1, 0) Re-Pressure Build-Up 60 seconds (0, 0) Expansion OFF (0) Compressor Sync ON (1) Expansion OFF (0)
(1) (1) (0) (0) (0) (0) (1) (0)
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 17
The optional iMAT on the pre-filter at the dryer inlet is supplied according to the power voltage indicated in the order; verify its compatibility with the information given on the type plate.
7.6 Service Reset Button
The service indicator LED can be reset after maintenance or service is performed on the dryer by pressing the RESET button located in the lower right corner of the controller.
After 360-days of the service indicator LED will flash amber indicating that service is due, and after 400­days the LED will flash red indicating that service is overdue.
7.7 Power Requirements
The controller operates on 100-120VAC / 50-60Hz. The units are shipped with an installed standard US 120 volt cord for convenience. Before starting up the machine it is necessary to have a qualified electrician review the electrical requirements schematic and install to the National Electric Code. Please refer to Section 12.
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 18
8. MAINTENANCE AND SERVICE
The service must be carried out only by a qualified technician.
Before any service is carried out, always verify that:
The power has been disconnected following proper Lock-out, Tag-out procedures Depressurize the unit and ensure the unit is isolated from the compressed air system (see pg 14)
The personnel that service the machine must wear hearing and eye protection before operating the dryer. Each employee must select a proper personal protection device (PPD) hearing protector such as earmuffs, ear canal caps or earplugs in order to prevent permanent hearing damage or loss.
DAILY
Check that pre-filter condensate drain is working properly Check the differential pressure of any installed pre and post filtration Check that the tower switching operation takes place correctly at the set cycle times. Check that the tower pressure gauge of the regenerating tower reads 0 psig while the drying tower
reads full line pressure
ANNUALLY
Replace the pre and post filter elements Replace the exhaust silencers Replace the pre-filter float drain or iMAT service unit Check if the solenoid valves are working properly Check if all screws of the electrical wiring are securely tightened Verify operation of the dryer
EVERY 2-YEARS
In addition to the scheduled annual maintenance:
Install inlet and purge exhaust valve service kit Verify operation of the dryer
EVERY 3-YEARS
In addition to the scheduled annual maintenance:
Replace the desiccant adsorption material in both towers The estimated average lifespan of the adsorption material is 3-5 years when using 10-minute cycle
times or 3,000 operating hours per year. In all cases, the lifetime of desiccant material is heavily dependent on the quality and temperature of the inlet air and ensuring that scheduled maintenance is consistently carried out.
Verify operation of the dryer
8.1 Routine Maintenance
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 19
The fuses can break if there are any problems with the dryer. In which case, only a certified technician can replace the fuse, but only after solving the problem that caused the malfunction first. Refer to Section 9, ‘TROUBLESHOOTING GUIDE’.
8.2 Maintenance and Service Intervals
Preventative maintenance of the pre- and post-filter element, and desiccant material is required.
The controller monitors the dryers operating hours and will activate the maintenance alarms after the following intervals:
360 Days: Amber Service Light 400 Days: Red Service Light
The dryer system should be check for items that require standard replacement and maintenance such as: the filter elements, exhaust silencers, and desiccant material.
NOTE: The maintenance alarms (reminders) do not change the operation of the controller in any way.
8.3 Fuses
One safety fuse is fitted on the electronic board, in positions F1. The fuse protects all circuits the electronic board of the BEKOMINI controller. The replacement fuse type is:
T1A type Radial lead fuse, PCB style
iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 20
8.4 Desiccant Replacement
CAUTION: Activated alumina desiccant dust is considered a nuisance dust. Proper precautions should be
taken prior to replacing the desiccant material in the dryer. Please refer to the Material Safety Data Sheet (MSDS).
1. Isolate and shut down the dryer (see page 14).
2. Place a suitable container at the edge of each drain port on the bottom of the towers that are located on
the sides, facing outward.
3. Open the drain ports on the bottom of the towers and catch the desiccant in the containers.
4. Refill each tower with the recommended type, size and quantity of desiccant. Only use manufacturer
supplied desiccant, which is high quality, high capacity desiccant designed and sized for the dryers.
5. Carefully knock on the sides of the tower chambers while filling so that the desiccant will pack tightly.
Some settling may be required in order to fit the specified fill amount into the tower. Tank sizes may be the same for multiple models, so do not be concerned if the tower is not entirely full.
6. Desiccant that has been contaminated with oil or other substances may require different disposal
methods and procedures than desiccant that is being replaced due to aging. Consult the appropriate MSDS and follow all applicable laws and regulations regarding disposal.
1. Isolate and shut down the dryer (see page 14).
2. Make certain that there are no “pockets” of pressure contained by the various valves.
3. Open the bleed valve on the bottom of the control air filter housing.
4. Loosen the “one touch” pneumatic fitting (no tools required) that attaches the control air tubing to the
valve body. Carefully move the tubing aside and out of the way. We suggest
5. Disassemble the valve for cleaning or repair. Service kits are available for all valves (see page 30).
6. Reassemble the valve and ensure that all O-rings, gaskets and components have reassembled or
replaced accordingly.
