The compressors are used for two classes of systems and are called:
LST - Low Torque de Partida, used in capillary systems.
Ex .: Refrigerators, Freezers, Commercial Counters, Drinkers and Refreshers.
HST- High Starting Torque, used in systems with conventional expansion valves.
Ex .: Commercial Counters, Exhibitors, Butchers and Refrigerators.
Definition of compressor application range
HBP - High Return Pressure
(Evaporation temperatures from -5 ° C to + 15 ° C)
Ex .: Dehumidifiers, Refreshers, Drinkers and air conditioners.
MBP - Mean Return Pressure
(Evaporation temperatures from -30 ° C to 0 ° C)
Ex .: Commercial Counters and Drinkers.
LBP - Low Return Pressure
(Evaporation Temperatures -40 ° C to -10 ° C)
Eg: Freezers, Refrigerators and chambers for freezing.
Whenever you want to replace a compressor it is very important to check which was the original compressor, because the operating conditions of a compressor can vary according to each project (equipment).
