RDH Series Refrigerated Compressed Air Dryers

High Inlet Temperature - 20 to 100 SCFM

 

RDH Series Refrigerated Compressed Air Dryer


Excessive water vapor in compressed air systems can cause equipment failure (freezing of outdoor air lines, corroding pipes, tools and much more) creating costly down time.

RDH Refrigerated air dryers provide clean dry air for use in commercial and industrial processes by removing water vapor from the compressed air. Ideal for body shops, paint booths or wherever a high inlet air temperature dryer is required.

PUREGAS' high inlet temperature refrigerated air dryers come complete with integrated aftercooler, built-in filtration, and two timer solenoid drains.  RDH refrigerated air dryers can handle high temperature applications up to 210°F.
