The success and achievements of Bitzer Kulmaschinenbau GmbH began with series production of the OST7061 type screw compressor in the assembly plant in Sindelfingen on January 26, 1983. At that time, annual production was only about 500 compressors. By the end of 2003 it should increase to about 13,600 compressors. The production of this series in 1983 and its successful operation helped to refute the argument that screw compressors with a volumetric capacity of less than 300 m/h should not be used.</p>screw compressorsBitzer20 yearsrefrigeration systemsair conditioning systemsвинтовые компрессорыБитцер20 летхолодильные системысистемы кондиционирования воздуха
