1.3 Safety precautions during installation
Precautions during installation
1. The dryer must only be lifted using suitable equipment and in accordance with the applicable safety
regulations. Loose or pivoting parts must be securely fastened before lifting. It is strictly forbidden to
dwell or stay in the risk zone under a lifted load. Lifting acceleration and deceleration must be kept
within safe limits. Wear a safety helmet when working in the area of overhead or lifting equipment.
2. Place the dryer where the ambient air is as cool and clean as possible. If necessary, install a suction
duct. Never obstruct the air inlet. Care must be taken to minimize the entry of moisture at the inlet air.
3. Any blanking flanges, plugs, caps or desiccant bags must be removed before connecting the pipes.
4. Air hoses must be of correct size and suitable for the working pressure. Never use frayed, damaged or
worn hoses. Distribution pipes and connections must be of the correct size and suitable for the
working pressure.
5. The aspirated air must be free of flammable fumes, vapors and particles, e.g. paint solvents, that can
lead to internal fire or explosion.
6. Ensure that all piping is free to expand under heat and that it is not in contact with or close to
flammable materials.
7. No external force may be exerted on the air outlet valve. The connected pipe must be free of strain.
8. If remote control is installed, the machine must bear a clear sign stating "Danger: This machine is
remotely controlled and may start without warning".
The operator has to make sure that the machine is stopped and that the isolating switch is open and
locked before any maintenance or repair. As a further safeguard, persons switching on remotely
controlled machines shall take adequate precautions to ensure that there is no one checking or
working on the machine. To this end, a suitable notice shall be affixed to the starting equipment.
9. The electrical connections must correspond to the applicable codes. The machines must be earthed
and protected against short circuits by fuses in all phases. A lockable power isolating switch must be
installed near the equipment.
10. On machines with automatic start-stop system or if the automatic restart function after voltage failure
is activated, a sign stating "This machine may start without warning" must be affixed near the
instrument panel.
11. Never remove or tamper with the safety devices, guards or insulation fitted on the machine. Every
pressure vessel or auxiliary installed outside the machine to contain air above atmospheric pressure
must be protected by a pressure-relieving device or devices as required.
12. Piping or other parts with a temperature in excess of 80˚C (176˚F) and which may be accidentally
touched by personnel during normal operation must be guarded or insulated. Other high-temperature
piping must be clearly marked.
13. If no safety valve is present in the air net close to the desiccant dryer (e.g. safety valve of
compressor), full flow safety valves must be installed on the dryer vessels.
14. If the maximum pressure of the compressor is higher than the design pressure of the dryer, a full flow
safety valve must be installed between the compressor and the dryer in order to blow off the excessive
pressure in case the safety valve of the dryer should be out of order or blocked.
Also consult following safety precautions: Safety precautions during operation and Safety
precautions during maintenance or repair.
These precautions apply to machinery processing or consuming air or inert gas. Processing
of any other gas requires additional safety precautions typical to the application which are
not included herein.
Some precautions are general and cover several machine types and equipment; hence
some statements may not apply to your machine.

2 General description
2.1 General description
Introduction
The air dryers described in this book are heatless adsorption dryers, built to remove moisture from
compressed air for industrial purposes. The standard version is intended to reach a pressure dew point
(PDP) of -40 ˚F. There is also a version available for a pressure dew point of -100 ˚F.
All dryers are designed for indoor use.
The dryers described in this book are equipped with a smart controller. A Pressure Dew Point (PDP) sensor
can be installed with a sales kit.
Main parts
A general overview of the main parts of the dryer units is given in below images:

Safety valve
If no fire extinguishing system is present close to the dryer, safety valves must be installed on the vessels of
the dryer in order to relieve the overpressure in the vessel because of fire in the neighbourhood of the dryer.
2920 1891 00 9
Page 12
Sonic nozzle (available as an option)
Excessively high air velocity (e.g. due to low inlet pressure) may cause the desiccant to "float" in the
vessels. The desiccant beads scrape against each other, creating additional dust. High-speed flow occurs
when a compressor starts against an empty air net or when working at a discharge air pressure that is too
low. A high volume of compressed air output can result in a pressure drop, which in turn increases the
speed.
Therefore, it is recommended to protect the drying medium against excessive volumetric flow through the
desiccant by installing a sonic nozzle.
Refer to the instruction delivered with the sonic nozzle to install and adjust it.
2.2 Operation
The construction of the air dryer is simple, reliable and easy to service. The dryer has two towers,
containing the adsorbing material or desiccant. The desiccant is a very porous grain material which can
adsorb large amounts of water vapor.
Instruction book
The operation cycle of the dryer is repetitive and is controlled by the Purelogic™ controller and a PDP
(Pressure Dew Point) sensor (when installed and activated).
The compressed air entering the dryer is led to one of the towers by means of the inlet valves (IV), which
are controlled by a pneumatic actuator (PA). As the air flows upwards through the tower, the desiccant
adsorbs the water vapor and the compressed air is dried. The dry air leaves the dryer via the outlet,
connected to the top of the tower.
While the desiccant in the first tower dries the compressed air, the desiccant in the second tower is being
regenerated. Regeneration of the desiccant is achieved by means of purge air from the drying tower: a
small portion of the dried air passes a nozzle (N), expands to atmospheric pressure and flows downwards
through the other tower, regenerating the desiccant. The regenerating air is released via the corresponding
exhaust valve (PV) and the silencer (S).
The regeneration time is regulated by a programmed half cycle time. Solenoid valves, controlled by the
controller, energize the pneumatic valves that determine the function of the towers. In case a PDP sensor is
installed and activated, a second small portion of the dried air flows via the control air valve (100), a small
air filter (101) and the pressure regulator (PR - only used on 232 psi versions) to the PDP sensor.
The PDP sensor constantly measures the pressure dew point of the air leaving the drying tower. As long as
the PDP temperature is below the set point (-40 °F or -100 °F), the drying tower will keep on drying, until
the PDP temperature exceeds the set point. On that moment the regenerated tower will start drying the
compressed air and the other tower will start regenerating. As long as the PDP temperature is below the set
point, regeneration of the non-drying tower is stopped after the pre-set time interval of the timer has
elapsed. As a result, reduction of purge air is achieved.

Piping
Make sure that all pipes, filters, valves, etc. are clean and that they are installed correctly
with or without bypass system.
Make sure that the piping is installed stress-free. For more information concerning air nets,
cooling systems etc. refer to the compressor installation manual.
To ensure correct operation of the dryer, it has to be fitted properly into the compressed air circuit,
consisting of the compressor, the dryer and the application.

General recommendations
Keep the following in mind when installing the dryer:
• Place the dryer at a location where the temperature never exceeds the limits; see Technical Data.
• The dryer does not require extra ventilation.
• Fix the dryer as level as possible to the floor. Make sure the fixating bolts are tightened firmly and
that the floor is suitable for taking the weight of the dryer.
• Provide enough space around the unit to install and service the filter elements. A minimum free space
of 800 to 1000 mm (approx. 2.6 to 3.2 ft) is recommended - see the installation proposal drawings.
Provide sufficient space under the filter elements to be able to replace the filter cartridges without
having to disassemble the piping.
• Always install a high efficiency filter (4) at the inlet of the dryer. A prefilter (3) is recommended to
extend the lifetime of the high efficiency filter. The drain pipes (1) of the water separator and the
filters must not dip into the water. Use a dust filter (5) at the outlet of the dryer. Should oil vapor and
odors be undesirable, a carbon filter can be installed downstream the dust filter.
• If the compressor has no built-in water separator, a water separator (WSD) has to be installed before
the dryer in order to prevent free water from entering the dryer, as free water can damage the
desiccant. If the condensate contains oil, install an oil/water separator for draining of pure condensate
water.
• It is recommended to install bypass pipes with ball valves over the filters in order to isolate the filters
during service operations without disturbing the compressed air delivery.
• It is required to install pressure relief valves on each vessel of the dryer when ball valves are installed
at the inlet and the outlet of the dryer to isolate the dryer from the air net.

To prevent free water from entering the dryer.
Never overload the dryer as a too high air speed will damage the desiccant. It may be
recommended to install the air dryer upstream of the air receiver to prevent overload (e.g.
after extending the dry air circuit). Consult your supplier if in doubt. See also section
Operating instructions for the correct operation procedure.
5.3 Electrical connections
The electrical wiring must comply with the local regulations. The air dryer must be earthed
and protected by fuses against short-circuiting.
2920 1891 00 49

6 Operating instructions
Safety
Always observe all relevant safety instructions.
Initial start-up
To start up the dryer for the first time or after a long period of standstill, proceed as follows:
1. Open the bypass valves (if installed) of the dryer.
2. Close the air supply towards the PDP sensor (dryers with PDP sensor).
3. Close off the air supply from the compressor towards the dryer by closing the external
inlet valve (if
installed).
4. Close the
outlet valve (if installed).
5. Remove the silencers to prevent the silencers from getting clogged by the desiccant and wear a dust
mask, safety glasses and ear protection. (This is only required at initial start-up or after the desiccant
was replaced).
6. Start the compressor and wait for pressure.
7.
Slowly open the inlet valve.
8. Check the connections of the dryer for air leaks and remedy if necessary.
9. Switch the dryer on by pushing the Start button (14) on the Purelogic™ controller.
10. Let the dryer operate for several hours with the external outlet valve closed.
11. In case the silencers were removed, refit the silencers.
12. Gradually open the external outlet valve.
13. If applicable, close the bypass valves of the dryer.
14. Open the air supply towards the PDP sensor (dryers with PDP sensor).
If the application allows air that is not completely dry, the valve towards the dry air
consumer may be opened even before the optimal Pressure Dew Point (PDP) is
reached. In this case however, it will take more time for the desiccant to dry completely.
At initial start-up, and specially when the dryer is loaded from the beginning, it can take
a long time before the dew point is reached.
For a dew point of -100 ˚F, it can take up to more than 10 days before this value is
reached.
It is therefore recommended to operate the dryer for a number of days with the outlet
valve closed.
2920 1891 00 51
Page 54
Normal start
If the dryer has not been used for more than 3 months, refer to section Initial start-up. In all other cases,
proceed as follows:
Instruction book
1. Cut off the air supply from the compressor towards the dryer by closing the external
2. Close the air supply towards the PDP sensor (dryers with PDP sensor).
3. Close the external outlet valve (if installed) between the dryer and the dry air consumer.
4. Start the compressor and slowly open the external inlet valve.
5. Switch the dryer on by pushing the Start button (14) on the Purelogic™ controller.
6. Gradually open the air outlet valve.
7. If applicable, close the bypass valves of the dryer.
8. Open the air supply towards the PDP sensor (dryers with PDP sensor).
Close the external inlet valve in case the compressor needs to be restarted. The high
air speed in the start-up phase of the compressor may damage the desiccant.
To prevent this, a sonic nozzle (available as option) can be installed

inlet valve.
During operation
At regular intervals, check the status of the LED’s on the control panel. Refer to section Problem solving.
If the PDP Warning LED is lit and the application allows only dry air, shut down the application and let the
dryer regenerate first. Check the PDP temperature regularly. If the PDP temperature is too high, let the
dryer regenerate by closing the outlet valve.
Stopping
To stop the dryer, proceed as follows:
1. If installed and if necessary, open the bypass valves of the dryer so that the application will still
receive compressed air.
2. Close the external inlet valve between the compressor and the dryer and the external outlet valve
between the dryer and the dry air consumer.
3. Let the dryer operate for a period without consumption, to depressurize the vessels.
4. Stop the dryer by pushing the Stop button (13) on the Purelogic™ controller.
The LED’s for PDP warning and PDP alarm are only functional if the dryer is equipped
with a PDP sensor!
52 2920 1891 00
Page 55
Instruction book
If the dryer is stopped for a longer period, keep the external inlet and outlet valve
closed to avoid moisture from entering the dryer.
Under no circumstances must compressed air be allowed to flow through the dryer
when the electrical power is switched off (regeneration of the desiccant material will no
longer be possible).

10 Instructions for Use
Instructions
Description
1 The dryers can contain pressurized air. This can be potentially dangerous if the equipment is
misused.
2 The dryer vessels must only be used as a compressed air vessel and must be operated within
the limits specified on the data plate.
3 No alterations must be made to the vessels by welding, drilling or other mechanical methods
without the written permission of the manufacturer.
4 The design pressure and temperature of this pressure bearing part must be clearly indicated
on the data plate.
5 If installed, the safety valve must correspond with pressure surges of 1.1 times the maximum
allowable operating pressure. This should guarantee that the pressure will not permanently
exceed the maximum allowable operating pressure of the vessel.
6 Original bolts have to be used after opening for inspection. The maximum torque has to be
taken into consideration (see table below).
