MYCOM Screw Compressors
Strong and reliable hearts of your refrigeration and gas compression systems

mycom screw compressors compact and powerful

Under the MYCOM brand, Mayekawa’s compressors are used worldwide in industrial refrigeration and freezing, heat pumps, and gas markets. Our compressors leverage thermal technology developed through years of experience to consistently provide high quality. We also offer a full lineup of environmentally-friendly compressors that use natural refrigerants. We have received high evaluations for gas compressors through our experience with helium, hydrogen, water vapor, chlorine, hydrogen chloride, hydrogen sulfide (excluding oxygen and acetylene), and other gases in dealing with resource- and energy-related problems. MYCOM compressors are highly trusted, having been used globally for over 70 years.
