In the context of negative changes occurring in the planets biosphere, such as pollution of the environment and the atmosphere, global warming, and depletion of energy resources, increasingly high criteria are imposed on manufacturers of refrigeration equipment, the most important of which are: (a) enhancement in the energy efficiency of refrigeration equipment; (b) decrease of material consumption of refrigeration units, and (c) use of clean and safe materials and refrigerants.
 The Taiwanese company, Fusheng, has been one of the world leaders in the production of screw refrigeration compressors for several decades. The experts at the company are always working to enhance the manufactured equipment and implement the most cutting-edge technologies.
 Recently, the most effective steps in this area have been the advancement and mastering of the manufacturing of special two-stage low-temperature screw compressors of the SRT series, as well as the production of compact screw compressors with an integrated BSR series oil separator with a variable compression ratio and semisealed screw refrigeration compressors with a volumetric capacity of 85 m3/h to 1946 m3/h
 The SRT compressor series consists of six types, with a first-stage volumetric capacity of 120759 m3/h and a second-stage volumetric capacity of 50300 m3/h
