Air dryer

Description
Air circuit
Compressed air enters heat exchanger (10) and is cooled by the outgoing, cold, dried air. Water vapor in
the incoming air starts to condense. The air then flows through heat exchanger/evaporator (4) where the
refrigerant evaporates, causing the air to be cooled further to near the evaporating temperature of the
refrigerant. More water condenses. The cold air then flows through separator (5) where all the condensate
is separated from the air. The condensate is automatically drained. The cold, dried air flows through heat
exchanger (10) where it is warmed up by the incoming air.
Refrigerant circuit
Refrigerant compressor (1) delivers hot, high-pressure refrigerant gas which flows through condenser (2)
where most of the refrigerant condenses.
The liquid refrigerant flows through dryer/filter (8) to capillary tube (7). The refrigerant leaves the capillary
tube at evaporating pressure.
