UA Series Non-Cycling Refrigerated Air Dryer

Typical non-cycling refrigerated air dryers operate at full power and remain on until they are manually switched off. Thus they are referred to as NON-CYCLING. They operate at full power when they are turned on and stay on even if no compressed air is flowing and your air compressor is turned off. It is common for users to leave the dryer on 24 hours a day, 7 days a week even when they are only operating one 8 to 10 hour shift. While the dryer is on during downtimes it unnecessarily consumes energy and causes wear and tear on the dryer.

PA series dryers are completely programmable to automatically turn ON and OFF as needed based on the end users hours of operation.
