Non-Cycling Refrigerated Compressed Air DryersNon-Cycling Refrigerated Compressed Air Dryers

Refrigerated compressed air dryers remove moisture and contaminants from compressed air systems by chilling the air to a temperature that causes the moisture in the air to condense and form droplets.

To optimize a compressed air system the moisture must be removed to avoid costly equipment failure, product contamination, and distribution system breakdown. A non-cycling refrigerated compressed air dryer uses a refrigeration system, heat exchanger, separator and drain to perform the drying operation providing compressed air that is useful for a broad range of applications.

The ERF series compressed air dryers are designed for ultra low pressure drops that range from 1.2 to 3.2 PSID. Competitive products can deliver pressure drops as high as 6.5 PSID. Additional pressure drop can substantially increase the operating cost of your dryer, each pound (PSI) raises the required compressor horsepower by 0.5%. If a facility is required to raise discharge pressure by 3 PSI to overcome component restriction (Pressure Drop), 1.5% additional compressor HP is required.

The GRF series encompasses models to handle compressed air flows from 10 to 2250 SCFM.  Our dryers utilize Stainless Steel heat exchangers with automatic or thermostatic expansion valves in lieu of the temperamental non adjusting capillary tube that are responsible for many compressor failures.

Each dryer comes with adjustable electronic timed condensate drain on units 40 SCFM and larger. Units that are smaller than 25 SCFM come standard with an automatic float type drain. Each unit has a heavy gauge steel cabinet for durability, and a 5-Year warranty.
