8. PRODUCT FUNCTION
8.1. Design and principle of operation
Dryer design
The AD model line of dryers consists of adsorption dryers based on
the PSA (“Pressure Swing
Adsorption”) method. Fig. 1. The dryer is composed of a compressed air cooler with fans (1),
condensate separator (13), inlet valve module (2), two chambers with replaceable cartridges filled
with adsorbent (3), outlet module (4) and control unit (5).
The inlet valve module is fitted with inlet (8 and 9) and regeneration (purge) (6 and 7) normally-
closed (NC) solenoid valves, which are used for cyclic chamber switching. Silencers (11) are
installed on the regeneration valves outlets. An outlet logic valve and purge orifices are installed in
the outlet module. The outlet module contains a dew point sensor in the “C” dryer versions.
Compressed air enters the equipment through the inlet (12) at the bottom of the cooler. The
compressed air outlet (17) is located in the output module.
The switch, power cord connector and control signal connector (e.g. from the compressor) are
placed from below at the front of the dryer. The RJ-45 Ethernet connector is located in the rear.
Principle of operation
Inlet air flows through the cooler and condensate separator into the valve module, where it is
directed into the active chamber with adsorbent, where the air is dried. The air then passes through
the built-in filters (see Fig. 1), outlet module and outlet filters (if the dryer is equipped accordingly)
to the outlet. A portion of the dry air (purge air) is directed into the second, regenerated chamber
from the outlet module through the purge orifices. The purge air with moisture removed from the
adsorbent is then released through the silencer. The chambers switch their functions cyclically.
Risk of high temperatures.
Placing air flow impediments upstream or downstream of the cooler is prohibited.
The temperature of internal and external parts of the equipment may rise to
hazardous levels.
