Open Coil Heating Elements

Typically the line voltage is specified by the customer and or end user.

Open coil heating elements.

First the watts volts and resistance must be determined for each coil in the heater. Selection of correct wire gauge wire type and coil diameter requires experience in industrial heating. Heating elements electric type resistance elements consist of a high temperature resistance alloys. 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. 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. 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 remain one of the most popular heating elements in use today. Open coil heater elements are made to fit inside standard 2 or 3 schedule 40 nps pipe. Standard air heating elements are available on the market but quit often they need to be custom built.
