Duct Heater

Duct Heater

DHE offers efficient electric duct heaters for all heating applications. Duct heaters used in forced air applications provide dedicated space heat or supplement existing heating systems. These heaters are equipped with the capacity to heat a large volume of air. They are equipped with the unique capability to both heat and cool the air simultaneously. A duct heater is a device that transfers heat from one source to another. It consists of a set of heating elements that are connected together in a framework or duct. The heating elements are detachable through the housing of this assembly. This eliminates the need to drag the entire heater out of the duct. As a result, downtime costs are reduced as each heating element can be replaced on its own. This type of industrial heater has been developed in a highly adaptable manner, providing the necessary features to be utilized in a variety of commercial and industrial applications.
