Open Coil Air Duct Heaters electric elements with high temperature heating wire

Short Description:

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 heater elements are an indirect industrial heating solution to decrease watt density requirements or the heat fluxes on the surface area of the pipe connected to the heated section and prevent heat sensitive materials from coking or breaking down.

    Advantages of Open Coil Heating Elements :

    In case you’re looking for a product that suits your simple space heating application, you’d better consider an open coil duct heater, since it provides lower kW output.
    available in small size compared to a finned tubular heating element
    Releases heat directly into the air stream, which makes it run cooler that the finned tubular element
    Has a lower drop in pressure
    Provides a large electrical clearance

    The selection of the correct wire gauge, wire type and coil diameter requires quite some experience. There are standard elements available on the market, but quit often they need to be custom built. Open coil air heaters work best below air velocities of 80 FPM. Higher air velocities could cause the coils to touch each other and short out. For higher velocities, select a tubular air heater or strip heater.

    The big advantage of open coil heating elements is the very quick response time.

    There are standard open coil heating elements available on the market and we carry some in stock. Most of these elements need a constant airflow over the resistance wire, but if the watt densities are low enough they may not burn out in still air.
