Air Duct Heaters

Air Duct Heaters

PMJ Air Duct Heaters are installed in plenums, ducts or pipes to heat forced air in industrial equipment and systems. A wide variety of heater designs and sizes are available to provide outlet air temperatures up to 600°C. The air can be either recirculated or fresh. Recirculated air is used to reduce power consumption and heater size. Fresh air is used when ventilation of the process is necessary. Air duct heaters are installed in ovens, furnaces, autoclaves, dryers, conveyor systems, pressure vessels, and other equipment to supply the precise amount of clean heat.
 
We can supply individual finned elements for use in OEM equipment or entire duct heater assemblies where we have complete control over the product including the elements, frames and controls. PMJ has earned an outstanding reputation for exceptional quality, reliability and long life.
