MATHESON has completed the construction of a new large capacity Air Separation Unit (ASU) in Lakeland, Florida. Inspection and testing is completed, and the plant is fully operational.

“MATHESON’s ASU fleet extends from Southern California, across the South through the Gulf States, and into South Florida. This new Air Separation Unit in North Florida will improve our coverage footprint, address a growing region, and allow MATHESON to better support our current merchant liquid customers with even better service and increased reliability,” stated Nigel McMullen, MATHESON Senior Vice President.

The new ASU is part of MATHESON’s ongoing strategic expansion plan to invest capital in growth markets and strengthen the reliability of its existing network. The plant produces Liquid Nitrogen, Liquid Oxygen, and Liquid Argon.
