CSR Series

Each compressor is under 42bar hydraulic pressure examination to ensure the safety of its structure.
The BSR screw refrigerant compressors are built with high-precision helical rotors and they feature minimal backlash, highly efficient operation, and compact structures. The compressors are small, easy to install, and they minimize low pressure loss and vibration. These units offer precise volume control, and a long service lifespan. The BSR213S to BSR616 produce discharge volumes of 143 to 2351m3/hr (60Hz).
The BSR series have been the best selection for various application industries, including air conditioning systems, hi-tech dust-free rooms, climate control rooms, and food refrigeration systems.

FEATURES
This series has a complete product line that can satisfy application demands from 25 to 500USRT. Twin-compressors can output up to 1000USRT and can directly replace centrifugal compressors. When used in combination with variable frequency (20~80Hz) and the patented real-time adjustable volume fraction (VI1.5~3.5) mechanical structure, the average energy-efficiency value would be 10-20% greater th
The highly efficient electric motor, from a well-known brand, is recognized for its excellent stability and efficiency. It was built with a PTC thermistor and the newest protection module to accurately monitor the coil temperature of the motor and to ensure its normal functioning. The optimum design of the cooling channel further expands the application scope.
The Fusheng 5:6 asymmetrical rotor tooth is processed and formed by the British HOLROYD rotor processing machinery and the German KAPP and KLINGELNBERG precision rotor grinder. Rotors are strictly measured by the German ZEISS and LEITZ three-coordinates measuring machine. They are tremendously precise, efficient, stable and reliable. Optimal clearance values between rotors are maintained, even un
The specially designed three-stage high density oil/air separator has a 99.7% oil separation efficiency. The oil filter features outstanding precision and can prevent foreign materials from entering the capacity regulation chamber and the bearings. The extensive low-pressure loss inhaling filter can increase the evaporation temperature and the overall energy-efficiency value.
This series features optimized volume fraction settings, an outstanding motor match, and an outstanding COP value. Variations in matching between the coolant and refrigerant oil are available to enable the best functions in the wide range of applications.
The capacity regulation valve can control the capacity modulation of the system precisely. A selection of patented four-stage and step-less designs are available for controlling the capacity regulation of the compressor. Various built-in volume fractions can be chosen for application to different coolant operating modes. An outboard solenoid valve is used for control and in-load.
