About Chromalox
Chromalox is a manufacturer of electric thermal solutions headquartered in Pittsburgh, USA, founded in 1917 by Edwin L. Wiegand on the basis of his patented metal-sheathed resistance-heated element. The product portfolio includes heat tracing systems including self-regulating heating cables, industrial process heaters, tank heating with panels, controls and sensors, cold weather and freeze protection solutions, and potable water heaters compliant with NSF/ANSI/CAN 61. In the field of component technologies, the company manufactures cartridge and insertion heaters, flexible heating elements, strip and ring heaters, tubular heaters, enclosure heaters, as well as controls and sensors. In addition, decarbonization and electrification solutions such as medium-voltage steam generators (CHSI Electric Boiler) are offered, which can replace gas-fired boilers. Industries covered include energy and nuclear power, oil & gas, data centers, aerospace, defense, semiconductors, chemicals, pharmaceuticals and biotechnology, medical technology, laboratory technology, agriculture, and municipal water supply. In addition to design, engineering and manufacturing, Chromalox offers Site Services: commissioning, service contracts, cold weather contracts, maintenance, diagnostics and emergency service. The company is part of the Spirax Group and operates worldwide with sales offices among others in Germany, China, India, Thailand, Singapore, Dubai and Hong Kong.
