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 PDF.
