Heat Exchange & Transfer, Inc. ADH Series Air Duct Heater ADH-54-243

Air duct heaters are available in standard and custom designs. The duct heater can be installed vertically or horizontally into a rectangular or square duct. Transition sections for circular or small ducts are available. The duct heater consists of stainless steel tubular elements welded into a steel mounting flange. The elements are staggered at a 30° angle to the direction of the air flow which generates turbulent flow and maximizes heat transfer. A stainless steel baffle provides additional support for the heating elements. The standard terminal housing is NEMA 4/12. High temperature units have a stainless steel mounting flange and high temperature insulation under-the-flange. Air duct heaters are available in a wide range of kW sizes, construction designs, NEMA ratings, controls and other options as listed on the back page.
