Chromalox has hit a new milestone! Since 1917 we've been driven by a pioneering spirit and built on opportunity and innovation. Chromalox was founded by a young engineer by the name of Edwin L. Wiegand. Through his intense curiosity in electrical conductivity, this led to the invention and patent of the electric resistance-metal sheath heating element that would create an entire industry. Chromalox has evolved to become the strong, respected, global industrial heating manufacturer with a well recognized global brand. Today we are known as the trusted experts who help companies solve the world’s most demanding and complex industrial heating challenges.

We want to take this opportunity to hear from you and thank you in sharing your stories or experiences with Chromalox.

Enjoyed My Career at Chromalox

I began my career at Chromalox in 1962 as a product specialist for radiant heaters. I left in 1963 to work for Faber associates, our rep in the NYC/NJ territory to work as an office application engineer and eventually became an outside sales and application engineer. I returned to Chromalox HQ in 1981.

Very Happy with Hot Water Heater

I have a Chromalox electric hot water furnace, 20 kW delivered by four 5 kw heating elements. It is neatly mounted on a wall. Although it is not the original furnace (which was oil-fired), it was installed before we bought the house in 1995, so it is probably a good 25 years old. It still works very well!

I have enjoyed working with your products

I worked at a pharmaceutical company as an electronic technician. We used small boilers for clean steam. I setup the controls on these units and set them up with Master and slave controls. I am retired now but enjoyed working with your products.

After 15 years, still a great place to work

I have worked at Chromalox in Nuevo Laredo Mexico for 15 years. It is a place that has given me the opportunity to grow and learn. This has made me appreciate a company that values you and gives you the opportunity to develop. It is a pride to celebrate the 100th anniversary with the Chromalox family and to be part of it.

Chromalox Heaters Saved Us Money

Using Chromalox electric immersion heaters, in the oil storage tanks, does an exceptional job of uniformly heating and separating the crude thereby eliminating the off-spec condition and the associated pricing penalties. This has worked well in dozens of plants throughout the oil industry.

Chromalox Heaters Still Working After 50 Years

I started doing work with Chromalox products, at the High Voltage Services substation, in Toronto Canada, in 1956, that uses Chromalox heaters. I also use Chromalox heaters in my oil reclamation machine which is still in use since 1963 and the heaters are FUNCTIONING LIKE NEW. The plant in Toronto also is still working!! Keep up the good work.

Chromalox heaters used on the US Space Shuttle Program

Chromalox heaters have been used on the US Space Shuttle program. As the shuttle re-enters the atmosphere, a large amount of heat is generated on the underside due to the speed it is traveling. Silica tiles are used to shield the shuttle’s equipment and personnel from the temperatures than can reach over 3,000 °F.
