High performance and reliability in a wide range of environments

KOBELCO has worked with compressors for over a century, manufacturing and selling over 10,000 units. Our users are located in Japan and more than 70 countries worldwide. Our compressors have been installed in power plants, steel manufacturing plants, and a wide range of other facilities. Their operation remains stable even under the extremely tough environment found in offshore oil and gas production facilities. Their world-class functionality and reliability have been proven time and again, satisfying even the demanding specifications of oil majors.

KOBELCO’s compressor technology for future energy

KOBELCO’s compressor technology and experience are being applied to the next-generation energy sector. Gas compression technology plays a vital role in producing, storing, transporting, and supplying hydrogen, LNG, and other alternative energy sources that could be promising substitutes for oil. By bringing this technology together with equipment such as heat exchangers and vaporizers, KOBELCO is working on improving process-wide efficiency and stability. These efforts are a solid first step on the path to carbon neutrality.
