ABOUT

Duct Heater

Duct heaters are devices that are an assembly of multiple heating elements mounted in a plate or casing and used to heat the air in a non-pressurized condition. The Heater bundle is usually inserted inside a duct line or an insulated body through which air passes and gets heated up to the required temperature.

Duct heater elements can be of open coil, tubular, or finned tubular heating elements, depending upon the application, temperature, etc. If an application needs a very large capacity of heat duty, several smaller capacities the duct heater bundles can be made and assembled in series. This will help not only to get the desired temperature at varying process conditions but also eases the job of maintenance and spare cost.
