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 outlet (4).
The cold, dried air flows through heat exchanger (1) where it is warmed up by the incoming air.
Refrigerant circuit
Refrigeration dryers of ID type contain high efficient refrigerant R410A of the HFC group.
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).
By-pass valve (9) regulates the refrigerant flow. Fan (10) is switched on or off by switch (11) depending on
the pressure degree of the condensate.
