Two-Stage Refrigerant Compressors (SRT Series)

Product Features

Specially designed for the pressure differential refrigeration and application to heat pump.

The Compound two-stage screw compressor is equipped with a pair of rotors respectively on high and low pressure for synchronous direct drive of the electrical machinery. It is also built with highly precise curved-tooth gear coupling to achieve the best state of balance and to make the entire design more compact and attractive.

Specialized Model for Low Temperature Refrigeration

• The evaporating temperature can go down to -60℃(R22) / -65℃(R404A).
• When running between -30℃ and -65℃, its efficiency is 30% greater than the single-stage screw refrigerant compressor and 20% greater than the low-temperature two-stage reciprocating compressor.
• Suitable for industries for rapid refrigeration during food processing, freeze dehydration of medicine, the low temperature petrochemical industry, rapid refrigeration during aquatic product processing, pelagic fishing freezer compartment, etc.

Specialized Model for High Temperature Heat Pump

• Wide operating range. Applied to high temperature heat pump unit with 85℃ hot discharged water.
• Specialized patent heat pump tooth being processed precisely to enable outstanding performances as high COP value, low vibrations, and low noise.
• Suitable for petrochemical industry, butchery, medical purposes, preheat of boiler, processing of plating, high temperature processing, etc.
