MATHESON has completed the construction of a new large capacity Air Separation Unit (ASU) in Mesa, Arizona, to meet the growing demand for industrial gases in the region. The ASU is fully operational and serving customers.

“This new Air Separation Unit will help support the strong economic growth in Arizona and surrounding areas and allow MATHESON to better support our current merchant liquid customers,” stated Nigel McMullen, MATHESON Senior Vice President.

The Mesa ASU is part of MATHESON’s ongoing strategic expansion plan to invest capital in growth markets and strengthen the reliability of our existing network.

The Mesa ASU produces gaseous oxygen, liquid oxygen, liquid nitrogen and liquid argon supporting manufacturing industries such as steel, fabrication, medical, water treatment, semiconductors, chemicals and food freezing.
