Distinctive system variations that ensure the essential stability of a gas supply

　"Mini on-site" is an original business model of Air Water that involves setting up a small- to medium-scale gas plant on-site at the user's production facility so as to provide them with a stable supply of gas. The core of this model is the "V-series" of small- to medium-scale cryogenic air separation systems that provide highly pure nitrogen and oxygen, which are essential to electronics and glass manufacturing. In 1984, Air Water utilized its unique technological advancements to successfully develop the V1 high-purity nitrogen generator, which is still being used at more than 120 locations throughout Japan. The "V-series" has established itself as a leading industry business model for providing a stable supply of gas that does not rely on distribution via liquefied gas tank trucks; this series has expanded its offerings to the V2, which generates oxygen, the V3, which co-generates nitrogen, and oxygen, and the proprietary VH, which supplies hydrogen on-site.
　In addition, the proprietary technologies cultivated as a result of the development of these mini on-site systems have found application in low-purity-type gas generation systems quite unlike cryogenic air separation-type systems, such as PSA-type oxygen generation systems optimized for paper and pulp and PSA-type and membrane separation-type nitrogen generation systems essential to shipbuilding, construction equipment and metalworking. This diverse lineup of products is part of what allows Air Water's Industrial Gas Business to provide "total gas solutions."
