    Open coil heater customzied heating elements for HVAC

     

    Open coil heating elements 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

    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.
