compressorScrew compressors


Screw compressors are positive-displacement compressors that feature space-saving designs, low maintenance costs, continuous operation and compatibility with a wide range of gases. There are oil-free (dry) types that prevent oil contamination of the process gas, and oil-cooled (wet) and screw refrigerator (ref) types that inject oil. KOBELCO has earned widespread user trust by providing custom-made API 619-compliant packages that conform to foreign or domestic regulations and meet user needs.
