We do it better, and we’ve been doing it longer than anyone else. We invented electric heating technology. Chromalox started with an innovative solution 100 years ago when a self-taught engineer invented the first metal-sheathed resistance heating element. It was this then-advanced-thermal-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. We excel in industries that have high expectations. And we are acknowledged as experts at delivering solutions that exceed specifications, limit risk, and reduce operating costs. Our Heat Trace Segment delivers Temperature Management Solutions for piping systems, valves, and tanks. Our Industrial Heaters and Systems Segment delivers Process Heating Solutions for revenue-generating industrial processes. Our Component Technologies Segment delivers Component Heating Solutions for industrial equipment manufacturers.

Wiegand, a self-taught engineer from Pittsburgh, PA, had always shown an intense curiosity in electrical conductivity. In his makeshift laboratory off his family’s dining room, Wiegand experimented with ways to encapsulate the fragile and sometimes dangerous “open coil” heat technology of the time in a dielectric. This led to his groundbreaking patent in 1915 of a resistance-heating element embedded in an insulating refractory and enclosed in a metal sheath. On this technology, he founded Chromalox in 1917 and began producing the strip heater for what would become the modern electric clothes iron. The next few decades were a boom period for Chromalox as electricity became a part of more homes and manufacturing plants. Heat and controls became integrated into systems, and Edwin Wiegand’s numerous patents found many applications in both the residential and commercial markets. World War II created an enormous demand for portable heat on land and sea. Chromalox joined the war effort, and continues to be an integral supplier to military and aerospace. Over the past half century, the ever-changing energy sector has opened up many areas for growth. Chromalox was the first supplier of pressurized heaters used in nuclear power plants and submarines. And as the world began shifting from fossil fuels to electric products, Chromalox has kept up with an ever-expanding portfolio of products and services around the globe. Chromalox is a premium provider of electric thermal technologies globally. We engineer advanced thermal solutions that deliver superior performance for our customer’s sustainable and mission critical applications. For more than 100 years, Chromalox has shaped the history of industrial process heating, and today leads the future transformation in energy, materials, advanced technology, and health and nutrition.
