Screw Refrigeration Compressors: BSR Series


Highly Optimized Structure and Application Design
  • Complete product lines (25~500USRT).Twin-compressors can output up to 1000USRT and can replace the centrifugal compressor directly.
  • The entire series is highly efficient and applicable to various industries, including air conditioning, high temperature heat pump, refrigeration and freezing, manufacturing processing etc.
  • When assorted with variable frequency (20~80Hz) and patent real-time adjustable volume fraction (VI1.5~3.5) mechanical structure, the energy-efficiency value in average would be 10-20% greater than the constant frequency model.
  • Extensive low-pressure loss inhaling filter can increase evaporation temperature and the overall energy-efficiency value.
  • Product safety certified (CE/UL/PED). The entire compressor is PED safety certified, and each compressor is under the 42bar hydraulic pressure examination to ensure the safety of its structure. It has a highly efficient electric motor.
  • Well-known branded highly efficient electric motor is equipped for its stable quality and excellent efficiency.
  • Built with PTC thermistor and the latest protection module to accurately monitor the coil temperature of the motor and ensure normal functioning.
  • Optimum design of the cooling channel extends the application scope effectively. High efficiency energy-saving rotor design
  • Equipped with a Fusheng 5:6 asymmetrical rotor tooth.
  • Rotors are processed and formed by British HOLROYD rotor processing machinery and German KAPP and KLINGELNBERG precision rotor grinder.
  • Rotors are strictly measured by the German ZEISS and LEITZ three-coordinates measuring machine. They are highly precise, highly efficient, stable, and reliable.
  • Best clearance value for the rotors even under consecutive operation to perform best efficiency. Durable Bearings and Optimized Oil Channels
  • Highly precise and big frame-sized western bearings are stable and durable.
  • Five- axial bearings offer better durability.
  • Built-in oil channels provide best lubrication and sealing, and can also minimize the volume effectively. High efficiency oil /air separator and large surface oil filter
  • Specially designed three-stage high density oil/air separator has 99.7% oil separation efficiency.
  • The oil filter is highly precise and can prevent foreign materials entering the capacity regulation chamber and the bearings precise and quick capacity regulation and control
  • Optimized setting of volume fraction
  • Different options of refrigerant oil
  • Best match of motor
  • Outstanding Coefficient of Performance (COP) value
  • Wide range of applications match with different types of coolant to enable best functions
