The adsorption dryer series PDAD is used whenever a pressure dew point of below -20 °C to -70 °C is required. It is ideal for decentralised compressed air drying.
Adsorption dryers have two cartridges that are filled with a drying agent. Moist compressed air flows alternately through each of the two cartridges, with the water accumulating on the surface of the drying agent. After a specified time, the air flow is switched to the other cartridge and part of the dried air (purge air) is used to regenerate the drying agent in the first cartridge.
The adsorption dryers PDAD are suitable for use as individual devices and can be integrated in service units of the MS series using the simple modular system of the MS series.
