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 the industry. It developed a broad customer base in the oil refining, petrochemical, chemical, fertilizer, and power generation market. Graham also supplies critical equipment and components for the Naval Nuclear Propulsion Program supporting aircraft carriers and submarine assets for our Nation’s defense.
