Nikkiso CE&IG lands major air separation unit contract with Matheson in Las Vegas (U.S.)

11/24/2025

Nikkiso Clean Energy & Industrial Gases Group has been awarded a significant contract by Matheson Tri-Gas Inc. to build an air separation unit (ASU) in Las Vegas, Nevada (U.S.), scheduled for completion in 2027. This project strengthens a multi-year partnership between the two companies and will expand industrial gas supply capacity across Nevada, California, Utah and Arizona.

Key highlights include:

  • Meeting growing regional demand: The new plant will produce oxygen, nitrogen and argon to serve the medical, fabrication, construction and food processing industries across four states.
  • Strategic partnership expansion: This project builds on several years of collaboration between Nikkiso CE&IG and MATHESON, combining Nikkiso's expertise in scalable, reliable air separation units with MATHESON's capabilities in packaged and specialty gas supply.
  • Operational synergy: Nikkiso CE&IG will source liquid nitrogen from the air separation plant for its nearby Las Vegas pump manufacturing facility to test cryogenic pumps before deployment.

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.”
