WATTCO™ process duct heaters are installed in forced air ducts and used for industrial processes (forced air dryers, core drying, annealing) that require medium to high air temperature (at least 750 ºF/400 ºC).

Process duct heaters come with the same standard and optional features as air duct heaters.
