Wire Wound Open Coil Elements Small Diameter Coils Heating Elements

Short Description:

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.

    Open coil heating elements from National heaters are typically made for duct process heating, forced air & ovens and for pipe heating applications. Open coil heaters are used in tank and pipe heating and/or metal tubing. A minimum clearance of 1/8’’ is required between the ceramic and the inside wall of the tube. Installing an open coil element will provide excellent and uniform heat distribution over a large surface area.

    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
