At Chromalox, we develop advanced thermal technologies for the world’s toughest industrial heating applications. 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.

Circulation heaters are packaged units designed to heat a flowing medium using in-line or side-arm piping configurations. Complete units consist of built-in heating elements, a heating chamber, thermostat and/or sensors (stock units), insulation, insulation jacket, mounting brackets and inlet and outlet connections. Circulation heaters offer high efficiency since all heat is generated within the solution. Fluids are directed past the heating elements giving fast response and even heat distribution. -
Integrating all the components – temperature controllers, overtemperature controllers and Power Controllers – into standard, off-the-shelf-panels, sets Chromalox apart from the competition. Chromalox stocks more standard power control panels, in different sizes and configurations than anyone in the industry. Choose from basic. single-circuit, low amperage contactor or SCR mini control panels to sophisticated, multiple circuit, higher amperage phase angle SCR control with full system diagnostics and several layers of process redundancy. Every panel is pre-engineered, field-proven and ready to install, and saves you the time and trouble of selecting, obtaining and assembling the various components. Select from pre-configured panels that include: • NEMA 12, 7, 4X or 4 Enclosure • 120-690 VAC • 25 Amps - 1200 Amps • Zero Cross or Phase Angle • Process/Temperature Controller(s) • Overtemperature Controller(s) • SCR Power Controller(s) and Fusing • Contactor(s) • Hybrid Contactor with SCR Trim Control • Pushbuttons, Switches, Indicators and Labeling Options • Agency Approvals (UL, CSA, cUL) -
Drawing on nearly 100 years of experience, Chromalox has an expertise that comes from working with world-scale engineering groups such as Bechtel and Flour-Daniel, U.S. military shipboard systems and the most demanding research institutions. Chromalox has encountered and conquered the challenges of even the most specialized requirements. This experience translates to efficient, economical solutions for your system's applications. -
Immersion heaters are designed for direct contact heating of water, oils, viscous materials, solvents, process solutions and gases. Since all heat is generated within the liquid or process, virtually 100% energy efficiency is achieved. Various temperature control options permit very tight process temperature control. Basic mounting options of threaded screwplug connections, flanges or simple over-the-side designs facilitate customer installation. A large selection of designs is available from stock for immediate delivery. Products are available for heating any fluid, from plain water to corrosive solutions, highly viscous oils, and for many specialized applications such as high pressure and hazardous areas. Custom engineered designs are also routinely manufactured by Chromalox. -
