Industrial and commercial electric duct heaters are wonderfully versatile—they can be used for paint drying or heat treating purposes as well as primary, secondary, or even emergency and back-up heating. They're easy to install and maintain, and with several mounting options, you've got great flexibility regarding where to install them.

As with other electrical heating solutions, they're an efficient choice and particularly cost-effective if you live in an area with low electric costs. You can further improve efficiency with well-maintained ductwork; check your ducts regularly to ensure they are thoroughly sealed and free from holes and leaks.

Trusted manufacturers like Markel, Warren, and others make commercial electric duct heaters with outstanding features like over temperature protection and SCR controls. With Warren's customized duct heaters, you can specify your duct size, heating capacity, power feed, and accessories and then select a vertical or horizontal mount along with your airflow direction and the location of the panel. Optional accessories include switch kits, transformer kits, and thermostats. Built with a hot-dipped galvanized steel frame and control panel and high-grade nickel chrome elements, Warren units are sleek, reliable, and easy to install.

Meanwhile, Markel offers dozens of models to ensure you can find an electric duct heater of the right size and heating capability for your commercial or industrial application. A division of TPI Corporation, Markel has been a trusted choice in heating for 100 years.
