Thermojinn BSV&BSW Series Two-Stage Piston Compressor

Short Description:

Thermojinn Semi-hermetic Two-stage piston compressors BSV&BSW Series includes 6 models. High-pressure displacement from 18-50.5 m³/h, Motor power :8-30HP. Applicability:R22,R404A and R507a. High efficiency, long durability,compact size and low vibration. The Two-stage compressor displacement is achieved through two consecutive compression. In First stage, the refrigerant gas from the evaporator is sucked from the inlet into the intermediate cavity. In second stage, the refrigerant gas is sucked in from the intermediate cavity and is compressed to the displacement pressure. Compared to the single stage compressor, the compression ratio of each stage of the Two-stage compressor is always lower. As a Result, the displacement temperature is lowered and efficiency is improved.
