Open Coil Heating Elements

Open coil heating elements from wattco are typically made for duct process heating forced air ovens and for pipe heating applications.

Open coil heating elements. Open coil heater elements are made to fit inside standard 2 or 3 schedule 40 nps pipe. Elements are formed from wire strip or mesh and can take numerous shapes such as sinuous or zig zag loops or helically wound coils. Open coil heating elements are coiled resistance wire usually ni chrome or kanthal but also others fixed onto a supporting element. 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.

Open coil heating elements remain one of the most popular heating elements in use today. Heating elements electric type resistance elements consist of a high temperature resistance 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. Or refractory metals such as molybdenum mo tungsten w or related alloys.

Open coil heaters are used in tank and pipe heating and or metal tubing. Iron chrome aluminum fecral. Typically the line voltage is specified by the customer and or end user.
