OPERATION Description
Pneumatic diagram
The construction of the air dryer is simple, reliable and easy to service. The dryer has two towers containing the adsorbing material or desiccant. This desiccant is a very porous grain material which can adsorb large amounts of water vapour.
Figure 4A shows the pneumatic diagram of the dryers:
The operation cycle of the dryers is repetitive and is controlled by a factory-set timer. While the desiccant in the first tower dries the compressed air, the desiccant in the second tower is being regenerated and vice versa. Regeneration of the desiccant is achieved by means of purge air from the drying tower. The compressed air entering the dryer is led to one of the towers by means of the inlet valve which is controlled by the pneumatic actuator. As the air flows upwards through the tower, the desiccant adsorbs the water vapours and the compressed air is dried. Once the top of the tower is reached, the air leaves the dryer via the outlet valve (= nozzle). The two pressure gauges indicate at all time the air pressure inside the towers.

PV ..Pneumatic valve
IV ... 3-way valve
S.....Silencer
N .... Nozzle
SV ..Solenoid valve
NV . Non-return valve
TV ..Pneumatic valve
P1 .. Pressure gauge 1 P2 .. Pressure gauge 2
A small portion of the dried air does not leave the dryer immediately via the nozzle valve but is expanded to atmospheric pressure and flows downwards through the other tower, regenerating the desiccant. This regenerating air is finally released via the solenoid valve and the silencer. A second small portion of the dried air flows via the control air valve, an air filter and the pressure regulator (only for the 16 bar units) to the solenoid valves which are controlled by the timer. The air leaving the solenoid valves (when energized) is used to control the pneumatic actuator and the pneumatic valves. After a certain period, the cycle will restart. The fully regenerated tower will now dry the air whereas the other tower will be regenerated. In case a power failure should occur during operation or in case the on/off switch was put in position O, the timer module will restart from zero. In case the remote control connector P4 was short-circuited, the dryer will remember the remaining drying time of the unit, continuing the drying cycle after connector P4 is opened again. P4 is connected to a NC voltage free contact of the compressor line contactor. If no free contact is available, an additional voltage free contact should be installed on the line contactor of the compressor. During unload, the outlet valve of the regenerating tower is closed. That way, the pressure in this tower will increase up to net pressure. From that moment on, purge air is no longer consumed. During load, the outlet valve is opened and both towers continue their cycle.

INSTALLATION Positioning
Concerning the piping, following checks should be carried out:
It is important to keep the following in mind when installing the dryer:
–
plugs and pipes must be removed before connecting the pipes,
–
Place the dryer at a location where the temperature never exceeds the limits.
–
make sure that all pipes, filters, valves, etc. are clean and are installed correctly with or without bypass system,
–
Provide enough space (approximately 80 cm) around the dryer for maintenance operations.
–
make sure that no external force is exerted on the piping.
–
Place the dryer as level as possible and fix it firmly to the concrete.
–
When the compressor has NO built-in water separator, a water separator has to be installed before the CD dryer, in order to prevent free water from entering the dryer.
Electrical wiring The electrical wiring must comply with the local regulations. The air dryer must be earthed and protected by fuses against short-circuiting. The four connectors of the timer module (refer to figure 6) have the following function:
Piping

clean. To ensure correct operation of the dryer, it has to be fitted properly into the compressed air system consisting of a compressor, the dryer and an application. The recommended installation, as shown in figure 5, can only be used in case the particular application allows to bypass the dryer. AR .......Air receiver BV .......Bypass valves Together with the external inlet valve and the external outlet valve, the bypass valves allow the dryer and the filters to be serviced while non-dried air flows through the bypass system.
P3 ....... Power supply of solenoid valve 2 Provides power supply to solenoid valve 2. P4 ....... Remote control connector Allows the connection between the dryer and the compressor for remote control of the dryer (refer to § Operation).
! Before switching on the main power supply, check the voltage requirements in the technical specifications or on the dryer’s data plate.
D .........Dryer EIV ......External inlet valve To cut off the air supply towards the dryer. EOV ....External outlet valve To cut off the air supply towards the air consumer. F1........Compressed air prefilter DD To remove water and oil droplets from the air entering the dryer. In this way, it prevents unnecessary overloading of the dryer and prolongs the life of the dessicant. F2........Compressed air filter PD To protect the desiccant against small particles dirt, water and oil. F3........Compressed air bypassfilter PD To protect the compressed air system against dirt, water and oil in case the dryer is bypassed. F4........Compressed air afterfilter DDp To protect the compressed air system against dust from the desiccant. WSD....Water separator (optional) To prevent free water from entering the dryer. The water separator must always be installed in case of 'Standard Pack Units'.
! If a valve is installed at the inlet and at the outlet of the dryer, a pressure relief valve must be installed on each vessel.
! Never overload the dryer as it 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 system). Consult Atlas Copco if in doubt.

The drainpipes (8) to the drain collector must not dip into the water. For draining of pure condensate water, install an oil/water separator. Consult Atlas Copco.
Waterseparator (7) : High efficiency waterseparator removes 90% in the compressor air when by-passing the dryer. If the WSD is not mounted in the compressor, a WSD need to be added in the installation downstream the vessel.
The installation sequence is Compressor (5) -vessel (6) -dryer. For the dryer there is no extra ventilation needed.
It is recommended to install pressure relief valves on each vessel of the dryer when there are ball valves installed at the inlet and the outlet of the dryer to isolate the dryers from the air net.
It is recommended to install by-pass pipes over each filter together with ball valves in order to isolate the filters during service operations, without distrubing the compressed air delivery.
An outlet dust filter type DDp (4) (particle removal down to 1micron) installed downstream the dryer. Should oil vapour and odours be indesirable, a QD carbon filter should be installed downsteam the DDp filter.
The inlet filter type DD (2) for general-purpose filtration (particle removal down to 1micron with a maximum oil carry-over of 0.5 ppm). A high efficiency PD-filter (3) installed downstream the DD- filter (particle removal down to 0.01 micron and max. oil carry - over of 0.01 ppm).
On both inlet filters a drain tube must be installed. The drainpipes to the drain collector must not dip into the water. For draining of pure condensate water, install an oil/water separator (Consult Atlas Copco).
The dryer unit (1) must be installed on a level floor suitable for taking the weight of the dryer. There must be a free space of 800mm around the dryer.

The drainpipes (8) to the drain collector must not dip into the water. For draining of pure condensate water, install an oil/water separator. Consult Atlas Copco.
Waterseparator (7) : High efficiency waterseparator removes 90% in the compressor air when by-passing the dryer. If the WSD is not mounted in the compressor, a WSD need to be added in the installation downstream the vessel.
The installation sequence is Compressor (5) -vessel (6) -dryer. For the dryer there is no extra ventilation needed.
It is recommended to install pressure relief valves on each vessel of the dryer when there are ball valves installed at the inlet and the outlet of the dryer to isolate the dryers from the air net.
