Open coil elements are the most efficient type of electric heating element while also the most economically feasible for most heating applications. Used predominantly in the duct heating industry, open coil elements have open circuits that heat air directly from the suspended resistive coils. These industrial heating elements have fast heat up times that improve efficiency and have been designed for low maintenance and easily, inexpensive replacement parts.

Open coil heaters are air heaters that expose the maximum heating element surface area directly to an airflow. The choice of alloy, dimensions, and wire gauge are strategically chosen to create a custom solution based on an application’s unique needs. Basic application criteria to consider include temperature, airflow, air pressure, environment, ramp speed, cycling frequency, physical space, available power, and heater life.
