Air Duct Heater

It’s common to install air ducts on the roof of industrial and commercial areas and buildings. Those primary uses for air ducts are the following: central air heating, ventilation and air conditioning. For a large building or structure, supplement heating is necessary to deliver the air at appropriate quality and temperature.

Duct heaters are ideal to warm low-pressure air flow via convection heating. For cold and humid environments, the air flowing temperature of the duct will gradually decrease across the duct wall. For this case, an air duct heater would be useful to supply the required heat in order to warm the building. A duct heater’s simple design and installation is the main feature for this product.

In addition, duct heaters have a large variety of application; for example, comfort heating, humidity control, freeze protection, heat treating, air pre-heating, etc. For large buildings and houses application, the primary use of air duct heaters is air ventilation system and comfort heating. A unit heater or a ceramic heater can be installed during or after the new building construction since this type of air heater can be easily removed and installed
