First the watts volts and resistance must be determined for each coil in the heater.
Open coil heating elements.
Open coil heating elements remain one of the most popular heating elements in use today.
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 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.
Heating elements electric type resistance elements consist of a high temperature resistance alloys.
Iron chrome aluminum fecral.
Open coil heater elements are made to fit inside standard 2 or 3 schedule 40 nps pipe.
Or refractory metals such as molybdenum mo tungsten w or related alloys.
Open coil heating elements from wattco 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.
Typically the line voltage is specified by the customer and or end user.
