Abstract

Despite the problems associated with the transition to the market, the staff of the Yaroslavl JSC "Kholodmash" concentrated its efforts on the development of production, the improvement of compressor technology and compressor building technology. Today Yaroslavl JSC "Kholodmash" has a wide range of compressors produced not only under license, but also on the basis of its own developments. In a short time, it was possible to put into operation an additional 22,000 m2 of production space, conclude a contract for the manufacture of 600,000 compressors per year under a license from Electrolux Compressors, and build a workshop for this. Compressors produced today comply with European quality and safety requirements and are fully interchangeable in terms of technical characteristics and connecting dimensions with similar models of compressors from ASPERA, UNIDAD HERMETICA, L’UNITE HERMETIQUE, etc.
Modern electrically insulating polyester materials, class 200 enamel wire, mineral and polyester refrigerating oils from the best foreign companies (such as MOBIL, SHELL and FUCHS) provide high quality and reliability of compressors when operating on ozone-friendly refrigerants. Quality control is carried out at all stages of production, from the input control of materials and components to testing on stands and final acceptance of compressors
