The main characteristic of AWI’s gas business is that we have the entire range of gas supply infrastructure, starting from high volume supply in on-site plants to small volume supply in cylinders, which makes us the country’s sole total gas system company.

For major clients who consume large quantities of gasses, such as the steel, chemical, and electronics industries, AWI set up dedicated gas production plants within the clients’ factories, or on adjacent premises, from where we offer stable supply, on a long-term basis, by piping industrial gasses essential for the production activities of various manufacturing industries.

Business is being expanded, mainly through on-site supply using “V-series” high-purity nitrogen and oxygen gas generators, according to customers’ needs. These industrial gasses are essential for the production of semiconductors, liquid crystal displays, silicon wafers, paper, and glass.

AWI offers specialized solutions for the electronics industries, such as the manufacturers of semiconductors, liquid crystal displays, and solar cells, mainly through Daido Air Products Electronics, Inc., which is a joint venture of AWI with Air Products and Chemicals, Inc. of USA.
