Flanged Duct Heaters 
Flanged tubular duct heaters are used for both natural and forced convection industrial applications. These units are a source of consistent heat in processes which require high air temperatures.

Durex Industries duct heaters feature heavy gauge mounting flange, terminal box, built-in thermowell, and rugged stainless steel construction.

Typical uses are high temperature drying, heat treating, annealing, process ovens, and other high temperature applications.
