134-IS Series, RefComp brand-new design specially for R134a refrigerant screw compressor with one inverter for energy control. It is mainly characterized by its integrated layout of the inverter (which is cooled by refrigerant) and the compressor, compact structure and convenience and reliablity in application, Compared with other models designed specially for R134a, this compressor has higher real operational efficiency and better flexibility. It has a frequency range of 30Hz – 70Hz, 26 models, with displacement ranging from 378~1540 m3/h (70Hz) and a nominal power ranging from 100Hp~420Hp (70Hz). Its innovative unique automatic compression ratio control technology ensures the compressor to its largest extent have the best efficiency in a relatively larger and various working conditions. Innovative compression ratio auto-adjust technology ensures the compressor’s high efficiency in various working conditions and under partial loads. It is widely applied in air-cooled units, various water and under-ground source heat pump units, ice-storage units, etc.
