The Refrigerated, High Temperature Air Dryers range from 18 to 52 SCFM and are designed to handle air-inlet temperatures up to 180° F. The digital control panel allows for control and modification of many operating parameters to ensure optimum performance.

These units are specifically designed for use with 5-25 HP reciprocating (piston) compressors.
