 Two Stage Screw Refrigeration Compressor Package Unit

The Application of Two Stage Screw Refrigeration Compressor Package Unit
Two stage screw refrigeration compressor package unit is a new type of high efficient screw compressor developed by Yantai Moon independently. There are five kinds of standard units, four open screw compressors and a semi-hermetic screw compressor. Open two stage screw refrigeration compressor is suitable for two kinds of refrigerants, ammonia and fluorine. Semi-hermetic two stage screw refrigeration compressor is suitable for fluorine, which is used for the evaporation temperature below -25℃, and the efficiency is significantly higher than the single stage economizer compressor unit.
