The heaters for the industrial environment are usually power by an electrical source. The heaters manufactured by WATTCO™ all electric heaters with heater elements made out of specially designed electric heating rods. The typical heating elements are made of steel or stainless steel. They are used in heating water or similar liquid medium for a general purpose and usually corrosion free.
Other corrosion resistant materials used are a composition of alloy such as copper or titanium. They are most resistant to high temperature and withstand the highly corrosive medium. Recently, specially manufactured alloy such as Inconel® and Incoloy® were introduced for more advanced application.
The heating elements are a vital part of the industrial heater with various added benefits contingent on a particular application. The selection of heating elements depends largely on the type and nature of the medium used. In addition to the medium, the type of heaters it will be installed also has a bearing on what kind of alloy it must be constructed of. These elements are factory configured into any shape and size. They operate in an extremely high temperature as some heater elements are required to operate well above the process temperatures of 1,600⁰F.
The use of exotic alloys further enhances the ability of the heating elements to withstand their inherent erosive nature. Copper, for example, does not react to water, so it could avoid normal oxidization. However, it ultimately reacts to the atmospheric oxygen over prolonged use and forms a layer of copper oxide instead of iron oxide. The use of titanium relieves much concern for corrosion as one of its properties is strong corrosion resistance. An added benefit of titanium is the nature of its feather weight as compared to other metals.
For extreme environments, WATTCO™ manufactures heater elements made with super alloys such as Inconel® or Incoloy®. The superalloys are mostly nickel-based and excellent corrosion-free materials typically suitable for environments under particularly high pressure and kinetic energy. They are also fully resistant to an extreme temperatures, specifically to certain chemicals otherwise not sustainable with the general alloys of heating elements. The heating elements are vital to the manufacturing of industrial heaters, and the proper choice of alloy under a specific condition is of the utmost importance to the designing of a suitable application for the particular industrial heater.
