Air dryer

Air Dryer

Wet compressed air enters the dryer and is further cooled by the outgoing, dried air (2). Moisture
in the incoming air condenses. The air then flows through heat exchanger (1) where refrigerant
evaporates, withdrawing heat from the air. The cold air then flows through condensate trap (4)
which separates condensate from the air. The condensate is automatically drained. The cold,
dried air then flows through heat exchanger (3), where it is warmed up by the incoming air.
