INSTRUCTIONS
After years of practice and working with clients, the BSR series screw refrigerant compressors have acquired numerous awards and certifications from various domestic and international institutes, including the UL(USA), CE mark (EU), PED(EU), ISO 9001, the Symbol of Excellence award (Taiwan), and many more. 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 than in a constant frequency model.
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 under continuous operation,
allowing it to perform at the highest efficiency.
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.
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.
