There are 14 models of Snowman SRS semi enclosed single-stage screw compressors, with an exhaust range of 85-500m3/h (@ 2960rpm) and a design pressure of 2.8MPa, suitable for refrigerants such as R717. The compressor has a compact structure, easy maintenance, low vibration and low noise operation. The compressor is equipped with a permanent magnet synchronous variable frequency motor, which adjusts the motor speed according to load changes to improve the efficiency of the compressor operation.
