Heatless Purge Desiccant Air Dryer

According to the principal of PSA, the moisture in the air will be adsorbed and compressed with the special appetency of the adsorbent on the steam. The machine is of two-tower structure.
Under the control of PLC, the two towers will run alternately. One tower adsorb the moisture under high pressure and another tower complete the desorption of steam with the dry air produced by itself , thus keeping running circularly. Although the machine will consume some air, the comprehensive energy consumption air largely lower than the heat sourced regenerative dryer based on variable temperature adsorption, so it is a widely used air compressing and drying machine at present.
