Chromalox, which joined the Spirax-Sarco Engineering group in 2017, is a leading provider of electrical thermal technologies for the world’s toughest industrial heating applications.


Chromalox invented electric heating technology 100 years ago when the company’s founder, a self-taught engineer, invented and patented the first metal-sheathed resistance heating element. It was this technology that launched an entire industry. That pioneering, innovative spirit continues today. Built on opportunity and innovation, Chromalox has grown to serve an increasing number of global markets and industries. ​


Heat Trace, which delivers Temperature Management Solutions for piping systems, valves, and tanks; Industrial Heaters and Systems, which deliver Process Heating Solutions for revenue-generating industrial processes; and Component Technologies, which deliver Component Heating Solutions for industrial equipment manufacturers. ​

Chromalox is highly complementary to the Steam Specialties business, with the decision between using steam or electricity as a heating medium being driven by differing needs of an application or customer circumstances.
