Refrigerant Dryer

The dryers of the PRD series are basically made by two different circuits. A compressed air circuit,divided into two heat exchangers and a refrigerating circuit. The hot and humid input compressed air passes through the air-air exchanger and then reaches the evaporator (air-freon exchanger), where it is cooled by the refrigerating circuit until it reaches the present dew point, thus condensing the humidity it contains. In the moisture separator the condensed humidity is then separated and removed by auto drain.
