In response to compressed air system demand, the dryer refrigeration system automatically cycles on and off to cool a thermal storage media. This media is circulated through a media-to-air heat exchanger, designed specifically for compressed air dryers, thereby cooling the compressed air and delivering dry air to the compressed air system. Condensed moisture is efficiently removed from the air stream via an automatic condensate drain.
