Compressed air circuit
Compressed air enters heat exchanger (1) and is cooled by the outgoing, cold, dried air. Water in
the incoming air starts to condense. The air then flows through heat exchanger/evaporator (2),
where the refrigerant evaporates, causing the air to be cooled further to close to the evaporating
temperature of the refrigerant. More water in the air condenses. The cold air then flows through
separator (3) where all the condensate is separated from the air. The condensate is automatically
drained through condensate drain (4).
The cold, dried air flows through heat exchanger (1) where it is warmed up by the incoming air.
Refrigerant circuit
Compressor (5) delivers hot, high-pressure refrigerant gas which flows through condenser (6)
where most of the refrigerant condenses.
The liquid refrigerant flows through liquid refrigerant dryer/filter (7) to capillary tube (8). The
refrigerant leaves the capillary tube at about evaporating pressure.
The refrigerant enters evaporator (2) where it withdraws heat from the compressed air by further
evaporation at about constant pressure. The heated refrigerant leaves the evaporator and is
sucked in by the compressor (5) through a liquid separator (12).
Bypass valve (9) regulates the refrigerant flow. Fan (10) is switched on or off by switch (11)
depending on the pressure degree of the condensate.
