A History of Cutting Edge Innovation

Founded in 1880 as Benjamin F. Kelley & Company, Harsco Industrial Patterson-Kelley has evolved over the years, continually adapting and changing to lead the marketplace. The company’s first product, feed water heaters, introduced pioneering technology with “U” tube bundles. Following the death of its founder, the Kelley Company merged in 1917 with his son-in law’s organization, Frank L. Patterson & Company. After World War II the business focus shifted from storage water heaters to more complicated, custom engineered heat exchangers and other commercial and industrial products. 

Following its 1974 acquisition by Harsco Corporation, Patterson-Kelley continued to lead the marketplace. In 1987, we entered the gas fired commercial boiler industry, developing new cutting edge products that solved customers’ problems. Innovation continues today with more recent developments like the MACH® high efficiency condensing boiler which is helping our customers reduce their fuel bills by as much as 80 percent.
