Open Coil Heating Elements

Open coil heater elements are made to fit inside standard 2 or 3 schedule 40 nps pipe.

Open coil heating elements.

Open coil heaters are used in tank and pipe heating and or metal tubing. Typically the line voltage is specified by the customer and or end user. Elements are formed from wire strip or mesh and can take numerous shapes such as sinuous or zig zag loops or helically wound coils. Iron chrome aluminum fecral.

In the design of a custom open coil heating element several factors need to be considered when selecting the optimum coil s for an application. Standard air heating elements are available on the market but quit often they need to be custom built. First the watts volts and resistance must be determined for each coil in the heater. Or refractory metals such as molybdenum mo tungsten w or related alloys.

Whether utilizing nickel chrome or iron based alloys open coil heating elements provide controllable electric heat in a variety of residential commercial and industrial applications. Open coil heating elements from wattco are typically made for duct process heating forced air ovens and for pipe heating applications. Selection of correct wire gauge wire type and coil diameter requires experience in industrial heating.
