Quincy Compressor

Regulating system and protection
The compressor is started and stopped automatically by a pressure switch (PS). A
pressure gauge (PI) indicates the pressure. A temperature switch (TSHH) protects the
compressor element from too high temperatures.
A safety valve (108) protects the compressor element against too high pressure.
Refrigerant dryer
Operation
The refrigerant dryer removes moisture from the compressed air by cooling it down to
near freezing temperature. The water is removed via an automatic drain.
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 the evaporator
heat exchanger (2) where the refrigerant evaporates, causing the compressed 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 water separator (3), where the
condensate is separated from the air. The condensate is automatically drained by the
electronic condensate drain (9).
The cold, dried air flows through heat exchanger (1) where it is warmed up by the
incoming air.
