100 Year Logo

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.
