Flanged Duct Heaters
Chromalox Flanged Duct Heaters consist of our ADH (800°F) and ADHT (1200°F) Duct Heaters which cover a multitude of applications. We offer both moisture resistant area designs that carry 3rd party listings and explosion resistant that do not. If you can't find the exact design you're looking for, our application engineering group can work with you to develop a custom configuration.
ADH & ADHT High Temperature Air Duct Heaters
Long Life Metal Sheath Tubular Elements — High grade INCOLOY® sheath material for excellent corrosion/oxidation resistance at high operating temperatures.
Sturdy Metal Sheath Elements minimize problems associated with open coil resistance wire units.
High Purity Magnesium Oxide — The elements are filled with highest purity blends of magnesium oxide refractory (MgO) compacted to a rock hard density to ensure good thermal conductivity and electrical insulation resistance.
Optional Gas Tight Design — Threaded fittings with fiber washers attach heating elements to flange — prevents leakage of ducted air into terminal housing.
Optional Overtemperature Protection — Thermocouple welded to the element sheath surface and wired to a terminal block allows for accurate overheat protection. Standard Type K thermocouple on ADHT high temperature heaters.
