24 November 2025
Temecula, Calif.– Nikkiso Clean Energy & Industrial Gases Group (Nikkiso CE&IG) announced today that it has been awarded a significant contract by Matheson Tri-Gas, Inc. (MATHESON, a wholly owned subsidiary of Nippon Sanso Holdings Corporation (TSE: 4091)) to build an air separation unit in Las Vegas, Nevada, scheduled for completion in 2027.
The new plant will produce oxygen, nitrogen, and argon to meet increasing demand for liquid gases in the medical, fabrication, construction, and food processing industries across Nevada, California, Utah, and Arizona.
As an added benefit, Nikkiso CE&IG will source liquid nitrogen from the air separation plant for its nearby pump manufacturing facility in Las Vegas to test the performance of its cryogenic pumps before deployment and installation.
George Pappagelis, President of Process Systems at Nikkiso CE&IG, said: “This project builds on several years of partnership between Nikkiso CE&IG and MATHESON, and again combines our expertise in building scalable, reliable air separation units with MATHESON’s capabilities in the supply of a range of packaged and specialty gases.
Mark Weir, Vice President of Onsite for MATHESON said: “We value this collaboration to work with Nikkiso in support of our customers located in the southeast region of the United States.”
