Electric air heaters are mainly used to raise the temperature of air circulating in a circular or rectangular duct for industrial processes or building air-conditioning applications. They consist of shielded electric resistors mounted in a steel or stainless steel casing.

In addition to the air-heating coil, you can use the control sensor with the Vulcanic supply and control box for complete control of your air-heating solution.
