High Capacity Heat Transfer Systems

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.

FEATURES

  • Seal welded elements prevent process gases from leaking into the terminal housing
  • Stainless steel baffle provides support
  • Designed for extended heater life by using low watt density elements and a staggered element pattern
  • Available with an explosion resistant enclosure
  • High temperature designs with under-theflange insulation are available
