The exhaust volume of SRS semi-hermetic single-stage screw compressors is 215-450 m³/h under 2960 rpm and the suction temperature from -45 ℃ to +20 ℃, with design of wide voltage range (380 V, 440 V, etc.). It is applicable to various refrigerants such as R717, R404A, R507A, R410A. It is characterized by compact structure, small size, high-pressure ratio, and low vibration and low noises during operation. The energy regulation can be chosen to be 25%-100% stepless or four-gear step regulation. The 30° design slope is applicable to vehicles like ships, to ensure efficient and stable operation under different working conditions. Snowkey semi-hermetic single-stage screw compressors are widely applied in such fields as refrigerated logistics, food processing, air conditioning, ships refrigeration and commercial supermarkets.
Features of SRS semi-hermetic single-stage screw compressor
- 5+7 best gear ratio combo; SRM "i" patented molded line; high intensity, high energy efficiency, and low noises
- New technology, max rotation speed of 6000 rpm, enhancing refrigeration capacity by 50 %
- Adopting a highly efficient sync variable frequency motor, which can regulate motor rotation speedbased on load changes, reduce operation power of the motor and raise its operating efficiency under low load
- Male and female rotors are arranged vertically to prevent accumulation of refrigerant oil on the motor bottom and facilitate flowing of refrigerant around the motor to make it fully cooled and operate at high efficiency.
- The screw rotor is processed to micrometer precision with tight gearing, even stress and a long service life
- Highly precise and wear-resistant rolling bearing with a design service life of 80,000 h
- World unique explosion-proof device for energy regulation cylinder
- Optimized design of suction and exhaust air ways, low suction resistance and fully cooling of motor coils; little exhaust throttling loss and low energy consumption.
