Information

In the 1930s, when Swedish engineer Alf Lysholm was researching gas turbines, he hoped to find a compressor with a rotary motion, which requires a much higher speed than the piston compressor, so that it can be directly driven by the gas turbine without surge. . In order to achieve the above goals, he invented the screw compressor.
   In theory, screw compressors have the characteristics they need, but because they must have a very large displacement to meet the requirements of gas turbine operation, screw compressors have not been applied in this field. Nevertheless, Alf Lysholm and his Swedish company SRM continue to conduct in-depth research on the application of screw compressors in other fields.
   In 1937, Alf Lysholm successfully developed two types of screw compressor test prototypes in SRM Company, and obtained satisfactory test results.
   In 1946, James Howden, a British company located in Scotland, was the first to obtain a screw compressor license from SRM in Sweden.
   Subsequently, many companies in Europe, the United States and Japan have successively obtained such licenses from SRM of Sweden to engage in the production and sales of screw compressors. The first screw compressor developed was an oil-free screw compressor.
  In 1957, the oil-injected screw air compressor was put into market application.
   In 1961, the oil-injected screw refrigeration compressor and screw process compressor were successfully developed.
   After the subsequent continuous basic theoretical research and product development test, through the continuous improvement of the rotor profile and the successful development of special rotor processing equipment, the superior performance of the screw compressor has been continuously exerted.
