Open Coil Heating Elements

Open coil heating elements remain one of the most popular heating elements in use today.

Open coil heating elements.

Selection of correct wire gauge wire type and coil diameter requires experience in industrial heating. Open coil heating elements are coiled resistance wire usually ni chrome or kanthal but also others fixed onto a supporting element. Standard air heating elements are available on the market but quit often they need to be custom built. Typically the line voltage is specified by the customer and or end user.

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. 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. Heating elements electric type resistance elements consist of a high temperature resistance alloys. Open coil heaters are used in tank and pipe heating and or metal tubing.

Or refractory metals such as molybdenum mo tungsten w or related alloys. 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 from wattco are typically made for duct process heating forced air ovens and for pipe heating applications.
