Founded in 1880 by Benjamin F Kelley, the company first started producing feed water heaters.

In 1974, after acquisition by Harsco Corporation, Patterson-Kelley continued to develop its products and in 1987 entered the gas-fired commercial boiler industry. In 2009 the Patterson-Kelley name was changed to Harsco Industrial Patterson-Kelley.
