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.
