REFRIGERATED COMPRESSED AIR DRYERS

By far the most popular type of dryer, refrigerated compressed air dryers are competitively priced, economical to operate, provide a stable pressure dew point and do not require much maintenance.  They provide a pressure dew point of 35 deg. F which is suitable when the air compressor and dryer are operating in ambient temperatures above freezing.

A refrigerated air dryer works by chilling the compressed air much like a refrigerator.  Wet air enters the dryer when it is cooled to approximately 35 – 38 deg. F (2 – 3 deg. C).  Water vapor in the air condenses to a liquid and is removed by a separator and automatic drain system.

The dry air is then re-heated to room temperature.
