Rotary Screw Refrigerant Compressor

Rotary Screw Refrigerant Compressors provides high volumetric efficiency but low power consumption.

SR Series Rotary Screw Compressors have five key features:

  1. High EER, Low Energy Consumption. The newly asymmetrical rotor profile, which has five lobes and six flutes in the male and female rotors respectively, results in a low pressure differential between flutes and provides high volumetric efficiency but low power consumption.
  2. Low Noise Level, Low Vibration. Rotors are precisely processed and dynamically balanced. Supported by high precise bearings, rotors can run smoothly.
  3. Precise Capacity Control System. Four-step or linear capacity control system is available for operations under variable loading conditions with minimum power consumption.
  4. Ease of Maintenance. With semi-hermetic design and limited components used, the detachable motor construciton makes compressors easy to maintain.
  5. Wide Application Range. The compressors can be widely used in water and air cooled air-conditioning systems, thermal storage system, heat pumps or industrial processes if external oil coolers, economizers or liquid refrigerant injection device is equipped.
