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 to lead the marketplace. The company’s first product, feed water heaters, introduced pioneering technology with “U” tube bundles. After World War II, the company's focus shifted from storage water heaters to more complicated, custom engineered heat exchangers and other heat transfer products. Click here to learn more about our history.

Following its 1974 acquisition by Harsco Corporation, Patterson-Kelley continued to lead the marketplace. In 1987, the company entered the gas fired commercial boiler industry, and innovation continues today with recent developments such as the P-K MACH® condensing boiler which helps our customers reduce their fuel bills by as much as 80 percent.
