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.
Since starting to manufacture and provide oil-free screw compressors in 1955, KOBELCO has delivered over 2,500 units to users all over the world representing a large number of applications such as oil/gas, oil refineries, chemicals and ironmaking.
KOBELCO started to manufacture and provide oil-injected screw compressors in 1974. Since then, we have delivered over 1,000 units to users inside and outside Japan for use in a large number of applications. Examples include hydrogen gas, helium gas, coke oven gas and gas turbine fuel gas. A recent example is low-pressure engine fuel gas for LNG carriers.
KOBELCO began manufacturing and provide screw refrigerators in 1963, and has delivered over 1,000 units to users inside and outside Japan since then.
