Medical Care

We supply medical gases essential for hospitals and home-based care, cryopreservation containers utilizing liquid nitrogen cooling, and stable isotopes of oxygen used for positron emission tomography (PET) diagnosis.



We mainly supply electronic material gases used in the manufacturing process of liquid-crystal and semiconductor (memory/sensor/logic), contributing to the development and dissemination of high-tech industry.



We provide a wide variety of products to create new lifestyles for a sustainable society.


Technologies Underlying Our Businesses

Three of the major technologies that underlie our industrial gas and electronics businesses are as follows.

・Plants & Engineering Technology

We have total factory and engineering technologies for the design, manufacturing, installation, and maintenance of air separation units (ASU). We have a track record of installing a number of highly-efficient plants with superior argon yield (air-derived argon collecting performance) both in Japan and overseas.


・Gas Handling Technology

With advanced expertise in the manufacture, mixing, and purification of various gases, we supply gases safely using the appropriate equipment and safety technology. We support the production activities of manufacturing businesses and provide various values to our customers and society.


・Gas Application Technology

Taking advantage of the combination of our unrelenting research and development of gas application facilities and equipment, and our gas handling technology backed by over 100 years of experience, knowledge, and accomplishments in gas supply, we offer gas application technology that leads to solutions to our customers’ requests, focusing on air separation gases and electronic material gases.
