HIT (High Inlet Temperature) refrigerated compressed air dryers are compact with highly efficient heat exchangers, no internal mesh to foul. Heat exchange efficiency is increased by creating helix flow paths in counterflow arrangement. The two stage separator/filter removes condensed oil ad water over a wide range of flows. A reliable condensate drain - air operated - automatically discharges water and oil from dryer without air loss and no timer to adjust. Our automatic refrigeration temperature control system maintains precise chilled air temperature that never needs to be adjusted for load, ambient or seasonal changes. No freeze ups! A Hermetic refrigeration system requires no maintenance & no adjustments - it operates as reliably as your home refrigerator.
