Our History

Nikkiso ACD began in the early 1950’s as an off-shoot of Aerojet General in Southern California manufacturing cryogenic pumps for Oxygen. It was subsequently acquired by an industrial gas company, the Air Research Company “AIRCO” and became the Airco Cryogenic Division “ACD”  which was the manufacturer of cryogenic equipment for the industrial gas parent. AIRCO eventually became BOC Gases and today is known as Linde; Nikkiso ACD was acquired by the Cryogenic Industries Group of Companies and today continues to operate as “Nikkiso ACD”.

By the early 1970’s, Nikkiso ACD had already outfitted entire fleets of LNG carriers with spray, emergency and main cargo pumps, warm up and boil off compressors and warm up heat exchangers. Over 100 carriers utilized Nikkiso ACD LNG equipment.
