1.0 INTRODUCTION

Ingersoll Rand DA Heatless Desiccant Dryers are designed

to adsorb moisture from compressed air. The DA dryers are constructed with two towers that alternate between online (drying) and oine (regenerating modes) in order to yield a continuous stream of dry air at the dryer’s outlet. Each tower contains desiccant beads.

During normal operation, wet air passes through the online tower and water vapor from the air is adsorbed (collected) on the desiccant beads. While air is being adsorbed in the online tower, the moisture on the desiccant in the oine tower is removed by a process called desorption (regeneration). After an initial rapid depressurization, a portion of dried air from

5.0 PRINCIPLES OF OPERATION

 5.1 INTRODUCTION

As described in SECTION 1, the DA series dryer is used to remove water vapor from compressed air by diverting air ow alternately between two towers that are lled with desiccant material. While one tower processes the compressed air stream by adsorbing water vapor, the opposite tower is regenerated by desorbing the water vapor accumulated in the previous cycle and venting it to atmosphere. Refer to SECTION 10, FLOW DIAGRAM for a visual representation of the drying and regenerating cycles.

Inlet ow to the dryer is directed to the bottom manifold and the outlet ow exits through the upper manifold. The manifolds are comprised of both pneumatically actuated valves and check valves that direct compressed air ow through the dryer.

 5.2 DRYING CYCLE

Saturated compressed air enters the dryer and is directed to the appropriate drying tower by the corresponding inlet ow valves. The inlet ow valves are normally-open and one of the valves will be actuated closed to direct the ow of compressed air to the designated drying tower. It is important to note that only one inlet valve is closed during this process. The FLOW DIAGRAM in SECTION 10 depicts the scenario where the left tower is being regenerated and the drying process is occurring with the right tower. In this example, wet compressed air enters the dryer and is directed to the right tower for drying when the left tower valve is actuated to a closed position. The normally-closed right tower purge valve is closed while the left tower purge valve is actuated to an open position during this period. As the compressed air ows through the desiccant material on the right tower, removal of water vapor from the air stream begins to occur through adsorption.

 5.3 REGENERATION CYCLE

Previously adsorbed moisture, removed from the process stream, gets stripped or desorbed from the desiccant material in the regeneration process. The rst stage of regeneration is tower depressurization. After the inlet Flow Valves are switched to divert air ow away from the regenerating tower, the appropriate normally-closed purge valve will be opened and the tower will be depressurized. Through rapid depressurization, a signicant portion of the previously adsorbed water vapor is stripped o the desiccant material and exhausted to the atmosphere.

DA Heatless Dryers are equipped with a downstream purge feature as standard. The downstream purge utilizes air from a downstream source to purge the regenerating tower. This feature is useful for applications with downstream (dry) storage tanks, as pulling air from a downstream source can minimize cycling of the air compressor.

 5.4 REGENERATION AIR FLOW

To enable the desiccant media within the towers to be thoroughly regenerated and to get proper dryer performance, purge air ow is factory preset. Setting the purge ow too high wastes compressed air and setting it too low results in the dryer not achieving proper dew point performance.

NOTICE

Do not restrict purge exhaust ow in any way. Keep purge muers clean. If exhaust air must be piped away from dryer, consult factory for correct pipe sizing and conguration.

 5.5 TOWER REPRESSURIZATION

Upon completion of tower regeneration, and prior to the inlet ow valves changing position to switch towers, the regenerated tower must be repressurized.

Repressurization is accomplished when the appropriate purge valve closes. Closing the purge valve allows the regeneration air to begin to pressurize the tower.

 5.6 VALVES

Control air solenoid valves (See Figure 2) are used to actuate the main ow valves and purge valves. The inlet ow valves are normally-open valves, while the purge valves are normally-closed valves. This arrangement permits air to ow through the dryer in the event of power failure. The control air solenoid valves are located on the bottom manifold assembly.

Figure: 2

The second stage of regeneration uses a portion of the dry, compressed air expanded to atmospheric pressure to complete the desorption process. As depicted in the FLOW DIAGRAM, the compressed air exits the drying tower and a portion of the air ows through the purge orice. Once the air has passed through the purge orice, it expands to atmospheric pressure and continues the regeneration process. Desorption occurs as the desiccant releases water vapor into the regeneration air that is then exhausted through the purge muer.

 5.7 TIMING SEQUENCE

A Digital Controller controls all dryer timing functions. The timing of Ingersoll Rand -40°F (-40°C) and -100°F (-70°C) dryers is outlined as follows:

Page 7

PPROVED 11/Jun/2020 11:47:53 GM

5.7.1 TIMING CYCLE FOR -40°F (-40°C) DEW POINT DRYERS

The standard timing cycle for -40°F (-40°C) operation switches the inlet ow valve position every ve minutes which alternates the drying tower. At the same time as a tower inlet valve opens, the appropriate tower purge valve opens to depressurize the regenerating tower. Tower regeneration occurs for 4 minutes and 10 seconds, at which time the purge valve closes to initiate repressurization.

5.7.2 TIMING CYCLE FOR -100°F (-70°C) DEW POINT DRYERS

The standard timing cycle for -100°F (-70°C) operation alternates the drying tower by switching the inlet ow valve position every two minutes. At the same time a tower inlet valve opens, the appropriate tower purge valve opens to depressurize the regenerating tower. Tower regeneration occurs for 1 minute and 50 seconds, at which time the purge valve closes to initiate repressurization.

NOTICE

Do not restrict purge exhaust ow in any way. Keep purge muers clean. If exhaust air must be piped away from dryer, consult factory for correct pipe sizing and conguration.

 5.9 ENERGY MANAGEMENT SYSTEM

The Energy Management System (EMS) feature is designed to minimize the use of purge air during low ow or low water loading conditions. On -40°F (-40°C) units, a dew point sensor samples the moisture content from the online tower and provides a signal to the controller. This function utilizes a dew point transmitter that monitors the dew point of the air exiting the dryer. Please note that the dew point transmitter should not be installed on a newly started machine until the dryer has operated continuously for a minimum of 24 hours.

 5.10 DRYER CONTROLS

The dryer is controlled by a digital controller that includes an illuminated display and keypad, accessible on the dryer main panel.

 5.8 COMPRESSOR INTERLOCK FUNCTION

DA40IM  DA300IM ONLY

The compressor interlock function enables the dryer to reduce the timing of the purge cycle based on compressed air demand. When the function is activated through the TECHNICIAN MODE within the digital controller, the controller monitors the cycle rate of the air compressor load/unload relay. The dryer will need to be eld wired to the normallyopen contact of the air compressor to allow the controller to monitor the cycle rate. The compressor interlock connections are depicted on the dryer wiring diagram (SECTION 9, Wiring Diagram).

It is important to note that the compressor interlock function is designed to be operated independent from the Energy Management System (EMS) option. For dryers equipped with the EMS option, the compressor interlock must be set to “OFF” in order to activate the EMS function. Setting the compressor interlock to “ON” in TECHNICIAN MODE will disable the EMS function.

For dryers equipped with the EMS option, the compressor interlock function can be used as a backup method to reduce purge air consumption when the dew point monitor is removed for calibration or for service. It is important to note that the performance of the dryer is based on the inlet temperature and pressure conditions along with ow. If the inlet temperature of the compressed air being supplied to the dryer is above 100oF (38°C), the user must exercise caution in order to prevent the desiccant beds from becoming overloaded, possibly requiring the compressor interlock function to be de-activated. Consult the factory for higher inlet temperatures (101°F/38°C - 120°F /49°C). Dryer sizing is aected by increased inlet temperatures.

6.0 INSTALLATION AND STARTUP

 6.1 APPLICATION AND CHECK ANALYSIS

To achieve the best dryer performance, you should carefully check that the design and installation requirements outlined below are satised.

NOTICE

The standard dryer is not rated for any gas other than air.

The dryer is designed to be operated with a compressed air inlet temperature ranging from 68°F (20°C) to up to 120°F (49°C) and at an operating pressure ranging from 60psig (4barg) to 200psig (14barg). The volume of air will be dependent on the system operating pressure. The air compressor delivering air to the dryer must be sized properly to handle both the demand and the purge air requirements necessary for regeneration.

 6.2 LOCATING AND MOUNTING

Use a forklift to lift the dryer only at the lift points identied with labeling. Use care to avoid damage to the manifold assembly. Bolt the dryer to the foundation using the bolt holes provided in the base frame. Anchor bolts should protrude a minimum of 1 inch (25 mm) above the foundation. Models DA5IM-DA25IM can be wall mounted (See Figure 3). Use appropriate size bolts to hold entire dryer weight.

Figure: 3

The factory should be consulted if the dryer is to be operated at pressures below 60psig (4barg) to verify sizing and proper conguration.

The standard dryer is rated to operate at an inlet temperature and pressure of 100°F (30°C) @ 100psig (7barg). The operating conditions should be veried prior to installing and operating the dryer to ensure it is properly sized. A dryer with greater capacity may be required to achieve expected dew point performance in installations with elevated inlet air temperatures. Lower inlet temperature conditions may also reduce dryer performance.

It is important to note that delivering lower compressed air inlet temperature levels will reduce drying performance. A minimum compressed air inlet temperature of 68°F (20°C) is required to be supplied to the dryer for proper operation.

The dryer should generally be installed in an enclosed area where the ambient temperature does not drop below 50°F (10°C) and is not above 115°F (46°C). Please consult the factory for outdoor installation applications where additional provisions may be required for lower ambient conditions.

NOTICE

Ingersoll Rand recommends the muers be cleaned after initial start-up to remove any desiccant dust generated during dryer shipment. After running the dryer for the initial 30 minute period, de-energize/ depressurize the dryer and remove the muers. Disassemble and clean the removable insert inside the muer core. Reinstall the muers prior to operating dryer. Periodic inspection of the muers is required to ensure proper dryer operation.

 6.3 PIPING

Pipe the compressed air lines to the inlet and outlet connections. When installing the prelters, which are shipped loose in the package, the prelters should be located as close to the dryer as possible. In addition, they should be positioned to allow for ease of service.

Note that the wet air inlet is at the dryer’s lower manifold, while the dry air outlet is at the dryer’s upper manifold. In situations where air supply is required 24 hours a day (where it is undesirable to interrupt the compressed air ow), an optional three valve by-pass system is recommended to bypass the dryer. To keep pressure drop at a minimum, the fewest elbows possible should be used. In order to prevent ooding of the desiccant bed when the dryer is o, the bypass should be used when troubleshooting the air compressor operation or when servicing the dryer.

Once all piping has been connected, all joints, including those on the dryer, should be soap bubble tested at line pressure to ensure no joints have been damaged in transit and during site placement. All installed piping must be self-supported. The dryer manifold piping cannot be used to support the interconnecting piping.

A minimum inlet temperature of 68°F (20°C) is required for proper dryer operation.

Page 12

PPROVED 11/Jun/2020 11:47:53 GM

 6.4 FILTRATION

NOTE: A prelter and an afterlter are provided with your dryer. Afterlters can be directly mounted on the dryers outlet while prelters need additional piping to allow the height to be sucient for maintenance purposes (See Figure 4 & 5).

Figure: 4

Figure: 5

Located before the dryer, coalescing prelters protect the desiccant beds from contamination from oil, entrained water, pipe scale and other contaminants. This extends the dryer’s desiccant life.

Prelters should be located as close to the dryer as possible and must be provided with drains to prevent liquid water from entering the desiccant beds. Drain maintenance is not covered by the standard warranty.

It is recommended that a mechanical separator with a properly functioning drain be installed immediately preceding the prelter to remove bulk liquid and entrained water.

The particulate/coalescing afterlter, located after the dryer, helps eliminate the possibility of desiccant dust carryover into the air system. To ensure proper dryer operation, the prelter drain(s) must be inspected periodically.

The outlet lter on models DA5IM – DA25IM can be mounted on left or right outlet connection (See Figure 6) while the opposite connection must be plugged.

Figure: 6

NOTICE

All DA model dryers must have proper ltration. Liquid water and oil must be removed before compressed air enters the dryer. Ensure Prelters and drains are in good working order. Failure to do so will void warranty.

DA dryer models are furnished from the factory with lters that include an automatic condensate drain valve. The drains require periodic inspection and maintenance to ensure proper dryer operation. Drain maintenance is not covered by the standard warranty.

Filters include an automatic drain valve. The drain valve must be checked for correct conguration prior to pressurization of the dryer as follows:

• Filters must be oriented vertically for proper operation.

• The drain stem must be properly adjusted as follows:

- Twist the drain stem (No. 18 in Figure 8) to set for AUTOMATIC (Normal) or MANUAL (Test) operation (See Figure 7 below).

- Twist the stem fully clockwise (when viewed from the bottom of the lter bowl) for AUTOMATIC draining of condensate. This is the Normal position.

- Twist the stem fully counter-clockwise (when viewed from the bottom of the lter bowl) for MANUAL draining of condensate (Test/Bleed) or if connected to an external drain.

Figure 8

Figure 7

MANUAL

AUTOMATIC

Minimum operating pressure of 22psig (1.5barg) is required for the oat that is within the drain assembly to seat properly. Pressures below 22psig (1.5barg) allow air to escape from the drain when the compressed air system is being pressurized.

WARNING

Proper safety precautions must be followed when servicing lters and drains. Filter bowl must be de-pressurized before servicing drain.

Service should only be performed by qualied personnel.

Before rst-time use, and after maintenance, the drain stem (See 18 in Figure 8) should be twisted fully clockwise to provide AUTOMATIC operation (See Figure 7).

Method of Operation (See Figure 8)

• When the lter pressure is below 22psig (1.5barg), the

piston (9) is held in an open position by the spring (3).

• When the lter is pressurized above 22psig (1.5bar), the

piston closes the drain aperture at the O-ring (13).

• As the condensate collects in the lter bowl, the oat (1)

is pushed upward, opening the nozzle (7) and allowing air to reach the top of the piston (9). This causes the piston to move downward, opening the aperture at the O-ring (13) for drainage of the condensate.

Maintenance and Initial Operation

• After initial startup, inspect drain(s) for system debris.

Clean as required. Float drain assembly is screwed into the bottom of the bowl from the inside.

• Drains require periodic inspection and maintenance to

ensure proper operation. Clogging of drains due to system debris or fouling is not considered warranty. Faulty drains must be returned to the factory for analysis in order to receive warranty credit.

Clogged drain screens can be cleaned by immersing the drain in a detergent and rinsing thoroughly in water.

 6.5 ELECTRICAL CONNECTION

Make all electrical connections to the dryer as shown on the wiring diagram (SECTION 9). Care must be taken to connect the proper voltages.

NOTICE

Dryer must be grounded with the full size ground wire connected to an earth ground.

NOTICE

Dryer must be fused according to NEC with the size fuse listed on the dryer serial nameplate, or on specication sheet in Technical Manual.

Size eld connection knock-out for the conduit tting required by the NEC. Installer must use UL Type 4 rated tting.

The compressor interlock wiring should be veried if this function is to be activated at start-up.

 6.6 DEW POINT MONITOR EMS OPTION

The dew point transmitter assembly (See Figure 9) that is supplied with the dryer as a separate component (when the dryer is ordered with the EMS option) must not be installed until the dryer has been in operation for 24 hours.

Figure 9

 6.7 STARTUP PROCEDURE

A Startup Form (included with the manual) must be completed and submitted with the Warranty Card as part of the commissioning process. This is included with the dryer at shipment.

Prior to pressurizing the compressed air system, conduct a visual inspection of the dryer to verify that the unit was not damaged during the installation process. This includes:

• Inlet and outlet compressed air piping connections are

properly supported.

• Extruded pressure vessels are not damaged.

• Gauges are in good condition.

• Pneumatic control air hoses, inlet and outlet compressed

air piping connections are properly supported and tightened.

• Prelter and afterlter bowl are properly tightened.

• Drain lines are installed to the lters. Refer to SECTION

6.4.1.

• Fasteners securing the dierential pressure indicator to

lter head are secured.

• Drain stem on each lter bowl is placed in the proper

direction such that it operates in the manual mode for initial startup. Refer to SECTION 6.4.1. The drains will allow air to escape until the system reaches 22psig (1.5barg) at which point the internal oat will seat properly and the drain will seal closed.

The dryer warranty will be voided if the dew point transmitter is damaged as a result of ooding condition.

NOTICE

The Dew Point Transmitter that is supplied with the dryer as a separate component must not be installed until the dryer has been in operation for 24 hours.

After the visual inspection is complete, slowly pressurize the dryer and perform a verication check on the following items:

1. Verify that the air outlet shut-o valve is closed (if this is provided for the dryer). This can be provided as part of a three-valve bypass option for the dryer or eld provided as part of the installation.

2. Check for air leakage prior to initiating ow through the dryer. Repair all leaks prior to starting the dryer. In order to maintain the drying performance of the dryer, any leaks must be xed; most important are leaks identied on the outlet side of the dryer.

NOTICE

DO NOT FLOW COMPRESSED AIR THROUGH THE DRYER WHEN THE DRYER IS OFF. The desiccant beds will become ooded with moisture and the Warranty will be voided.

Page 15

PPROVED 11/Jun/2020 11:47:53 GM

3. Verify that the prelter drain is blowing freely to drain residual water in the system. If no moisture is observed exiting the drain, turn drain stem to the automatic position. Verify drains ahead of dryer are functioning properly.

4. Turn the eld disconnect switch to the ON position to apply power to the dryer. This will energize the controller. Use proper PPE to verify that the voltage to the control panel matches the voltage/phase listed on the serial plate of the dryer. Do not apply power to the dryer until items 1-4 listed above have been veried. Do not apply power to the dryer or activate the dryer for operation until the air system checks are completed.

• For dryers equipped with the EMS option, do

not install the dew point transmitter until the dryer has operated for a minimum of 24 hours to reach steady state conditions. See the Warning note regarding installation of the dew point transmitter. Failure to follow this procedure will damage the dew point sensor and will void the sensor warranty.

5. The control air regulator located inside the top cover is preset to not exceed 100psig (7barg). The main ow inlet and purge valves are regulated to operate with a control air pressure level not to exceed 145psig (10barg).

after the dryer is placed into operation. Drain maintenance or cleaning of system debris is not covered under warranty. Improper drain maintenance will result in damage to the desiccant beds and will void the warranty.

• Once the system has operated for approximately

two hours, the muers will need to be inspected. Follow proper safety procedures prior to replacing the muers. Muers are consumable items and are not warranted other than for manufacturing defects.

• Monitor the operation of the dryer and contact

Ingersoll Rand if any problems arise during the startup process. The oat drains on the dryer's should be inspected daily to ensure proper operation.

• For dryers equipped with the EMS option, install

the dew point transmitter once the dryer has operated for a minimum of 24 hours and the BMI is fully blue in color. After the sensor has been installed, re-activate the EMS function through the settings screen.

• Verify (if wired) compressor interlock Function.

See SECTION 5.8.

9. Complete the warranty startup card after the dryer is fully commissioned.

6. Press the ON button on the dryer controller to initiate dryer operation.

• Observe the operation of the dryer and verify

that the dryer sequence is operating properly. The dryer controller will automatically sequence the valves. Do not allow the dryer to operate if problems are observed.

• Slowly open the outlet air shut-o valve (if

equipped) and allow the system to slowly pressurize.

7. Verify that the compressed air system remains pressurized.

NOTICE

At initial start-up, check the dryer operation for one or two cycles, especially at the time of the tower shift. Verify that all systems are operating in their proper order and sequence. If the dryer is not functioning properly, contact distributor or Ingersoll Rand Technical Service.

8. Verify the Technician and Maintenance settings of the dryer. Refer to SECTION 5.10 for further instructions.

• Verify that the oat drain(s) on the inlet lters

are operating properly. It is important to note that debris from the system piping may interfere with the operation of the oat drain and it is the responsibility of the installer to verify this

Long-Term Storage

If a dryer has been in storage for an extended period of time, follow the instructions above to start the dryer. Depending on the amount of time the unit was in storage, it may take between 8 and 12 hours before dryer would be regenerated.

NOTICE

When opening the outlet valve, ensure drying tower gauge maintains line pressure. Allowing the pressure in the dryer to drop will result in an overow condition and potentially cause valves to stop functioning.

NOTICE

-100°F (-70°C) dryers require ow through the dryer to lower the pressure dew point to design levels. Failure to permit air ow through dryer (deadheading) will result in elevated outlet dew points. Once air is permitted to ow through the dryer, the pressure dew point will gradually reduce to design levels.

PPROVED 11/Jun/2020 11:47:53 GM

 6.8 DRYER SHUTDOWN SEQUENCE

The following procedures must be followed to correctly terminate dryer operation:

NOTE: The DA dryer must remain pressurized during the shut-down sequence.

- Press the red “OFF” button to deactivate the dryer operating sequence and de-energize the control valves. The main ow valves will be positioned to the default position:

a.The purge valve will close b.The regenerating tower will re-pressurize c.The main inlet ow valves will open

The system must remain pressurized in order for the main ow valves on the dryer to revert to the default position.

- The status line in the home screen will display “OFF”.

- The system will remain pressurized at all times. The dryer does not contain any provisions to permit a system bleed down.

- The red “OFF” button only de-activates the dryer operating sequence - electric power will remain live within the dryer main panel.

WARNING

Failure to follow this procedure may result in the system retaining pressure within the dryer and potentially result in an unsafe condition for service personnel.

NOTICE

DO NOT FLOW COMPRESSED AIR THROUGH THE DRYER WHEN THE DRYER IS OFF. The desiccant beds will become ooded with moisture. The dryer Warranty will be void.

7.0 MAINTENANCE AND SYSTEM CHECK

 7.1 SCHEDULED MAINTENANCE

DAILY MAINTENANCE FUNCTIONS:

• Check and record inlet pressure, temperature and ow.

Verify that it is within specications.

• Check tower pressure gauge readings are within operating

tolerance (DA40IM - DA300IM only).

• Check dryer operation for proper cycling, depressurization

and re-pressurization.

• Check that the prelter drain is operating properly and that

there is no condensate discharged from purge muers.

• Verify that pressure in purging tower is 3psig (0.2barg) or

less. If higher, muer replacement is recommended. See SECTION 8.

• Check the dryer digital controller for alarms (DA40IM –

DA300IM only).

• Verify that prelter and afterlter dierential pressure

is within operating limits. Replace elements and/or cartridges as required.

MONTHLY MAINTENANCE FUNCTIONS:

• Check condition of muers by reading tower pressure

gauge when the tower is in the re-generation cycle. If pressure is above 3psig (0.2barg), muer replacement may be required.

 7.2 PREFILTERS AND AFTERFILTERS

PREFILTERS - The cartridges of the prelter must be changed as often as required to prevent contamination of the regenerative dryer’s desiccant bed.

The prelter and automatic drain must be checked daily. To prolong lter cartridge life, it is recommended that a mechanical air/moisture separator be placed immediately before the prelter.

AFTERFILTERS - The purpose of the afterlter is to remove residual desiccant dust. Depending upon equipment application and usage, frequency of lter element change will vary. It is recommended that, at the minimum, the lter element be changed every six months.

 7.3 PILOT AIR CONTROL SOLENOID VALVES AND

FILTER/REGULATOR

The length of time the pilot air valves can reliably operate without replacement is dependent upon the dryer operating cycle. On Ingersoll Rand -40°F (-40°C) dew point dryers, replacing the valves every 36 months is recommended. For

-100°F (-70°C) units, it is recommended that the pilot valves be replaced every 24 months. The control air regulator (See Figure 10) should be set for 100psig (7barg).

Figure: 10

NOTE: Ingersoll Rand recommends the muers be cleaned

after initial start-up to remove any desiccant dust generated during dryer shipment. After running the dryer for the initial 30 minute period, de-energize/depressurize the dryer and remove the muers. Disassemble and clean the removable insert inside the muer core. Reinstall the muers prior to operating dryer. This procedure should be repeated within the rst seven days of dryer operation.

SEMI-ANNUAL MAINTENANCE FUNCTIONS:

• Check outlet dew point (EMS option only).

• Replace prelter and afterlter elements and/or cartridges.

ANNUAL MAINTENANCE FUNCTIONS:

• Check desiccant and replace if necessary.

• Inspect and clean pilot air control solenoid valves, check

valves and ow valves. Rebuild and / or replace as required.

• Replace drains on prelter and afterlter.

• Test electrical components, replace as necessary.

• Check for loose electrical wiring connections and tighten

as required.

• Check and replace muers

EVERY THREE YEARS:

• Inspect pneumatic valves and replace angle valve bonnets

if not functioning properly (Preventive). Check and replace shuttle valve assembly

• Replace control air solenoid valve (Preventive).

• Re

lace desiccant.

 7.4 MUFFLER CHANGEOUT PROCEDURE

WARNING

To avoid injury, depressurize dryer before performing any service.

• Stop dryer cyclic function.

• Depressurize the dryer. Disconnect dryer from electric

power source.

• Replace muers.

• Follow Start-up Procedure described in SECTION 6.7.

• Turn control power back on.

Page 18

 7.5 ANGLE SEATED PURGE AND SWITCHING

VALVES

• Purge Valves – Normally-Closed (N.C.) for purge air ow.

Control air is supplied through tubing that is connected to the side port. When control air is supplied to the valve, a position indicator will extend from the top of the bonnet, indicating that the valve is open (See Figure 11).

Figure 11

 7.6 DESICCANT CHANGEOUT PROCEDURE

When it becomes necessary to replace the desiccant in the towers, observe the following procedure:

Units (DA40IM - DA300IM) are furnished with ll and drain ports (See Figure 12) on each extruded tower. Remove the caps on both ports. Units (DA5IM - DA25IM) are not equipped with drain ports, upper block cover needs to be taken o to change desiccant media

Figure 12

• To assist in getting the desiccant to ow from the tower,

insert a small rod into the drain port as necessary. This may be required as the desiccant is packed into the towers which may interfere with the desiccant ow from the towers.

• With the ll port plug removed, ll the dryer tower with the

appropriate grade and size desiccant.

• When the towers have been lled to the correct level,

replace the ll port plug on each tower.

• Any connections and joints disturbed in the desiccant

change out procedure should be leak tested prior to re-commissioning the dryer.

CAUTION

Desiccant will produce dust during the change out procedure. Be sure to wear respiratory protection during the draining and lling process to minimize inhalation of desiccant dust.

• Inspect purge valve & control air solenoid valves for proper

operation.

• Inspect muers for clogging.

• Inspect control air solenoid valves for proper operation.

• Check pressure source and inspect piping system for

leakages.

• Verify that the dryer was sized appropriately for the operating

conditions.

• Verify that compressor sizing is properly matched to dryer

capacity.

• For specialty systems where the outlet of the dryer is piped

to a booster compressor, verify that the ow of the booster compressor is below the rated capacity of the dryer. Excessive ow will uidize the desiccant bed and result in dusting and signicantly reduce performance.

• Inspect the air compressor after-cooler and drain to ensure

proper operation. After-cooler may require cleaning in to operate properly.

• Verify the inlet temperature does not exceed 120

F (50oC) under normal operating conditions. For applications that approach 120oF (50oC) on a continuous basis, dryer sizing should be reviewed prior to operation of the dryer. The standard design is rated based on an inlet condition of

100

F (38oC) @ 100psig (7barg) and will not deliver proper

performance if it is undersized.

• Verify that the air compressor after-cooler drain is

functioning properly.

• The desiccant will become saturated if compressed air is

permitted to ow through the dryer before it is operating.

• If this occurs, the performance of the dryer will not easily

recover and this will void the warranty on the desiccant material.

Follow proper safety pre-cautions during this process.
