Our History

Graham Corporation's earliest roots extend back to 1936 when Harold M. Graham first incorporated Graham Manufacturing Company. While the company's headquarters have remained in Batavia, New York since 1942, its reputation has extended around the globe.

During World War II, Graham supplied steam ejectors, surface condensers and heat exchangers for shipboard applications. After the war, the Company shifted to the engineering and manufacturing of customized vacuum systems, surface condensers and heat transfer products for industry. It developed a broad customer base in the oil refining, petrochemical, chemical, fertilizer and power generation market.  The Company added operations in Suzhou, China (Graham Vacuum and Heat Transfer Technology (Suzhou) Co., Ltd.) and in the northwest region of India, based in Ahmedabad (Graham India Private Limited). These subsidiaries expand market presence and provide sales, engineering and project oversight local to the customer.

Graham’s newest business is Barber-Nichols, which it acquired on June 1, 2021. 

Barber-Nichols, which was founded in 1966, brings its own rich history.  Bob Barber and Ken Nichols, two brave, if not naïve men, had a dream about working for themselves, doing things that could have a real impact on the world, and having a lot of fun in the process. They founded BN as a turbomachinery engineering company in 1966. Early on they saw the need to broaden the company’s capabilities to include manufacturing and testing their innovative designs.  Recently, BN has grown rapidly from programs that involve complex production and system integration. BN is located in Arvada, Colorado, a suburb of Denver.
