About Us

ACD

ACD is an engineering and manufacturing company specializing in machinery designed to operate at cryogenic temperatures as low as – 420 degrees Fahrenheit,  the boiling point of Liquid hydrogen. For over 50 years, ACD has specialized in centrifugal and reciprocating pumps as well as turbines for air separation.  ACD has the most diversified product line in the industry covering nearly every application requiring pumps or turbo expanders.

 

HISTORY

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; ACD was acquired by the Cryogenic Industries Group of Companies and today continues to operate as “ACD”.

By the early 1970’s, 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 ACD LNG equipment.

 

CUSTOMER BASE

Since the inception of the company, ACD has been a trusted supplier of equipment to some of the most prestigious companies in the world in some of their most delicate applications.
