Infrared Heating Element Manufacturers and Suppliers

To accomplish all tasks in the best way possible, infrared heating elements are made using a variety of different materials. First, many infrared heating elements are produced using wire coils wrapped in an insulating or protecting material. These wire coils are mostly made from tungsten, but they may also be made from other metals, such as nichrome, kanthal, and cupronickel. Nichrome, also known as chromel, is a mixture of nickel and chrome, with the dominant element being nickel. It exhibits high levels of resistance, and the first time it is heated, it forms an adherent layer of chromium oxide. This layer later serves the heating element well, preventing the material beneath it from oxidizing and deteriorating faster. “Kanthal” refers to an entire class of alloys. Alloys in this class are highly resistive and are composed primarily of iron, chromium, and aluminum. Cupronickel, also known as copper-nickel, is another resistive wire. This alloy is composed of, as its name suggests, copper and nickel. Other materials that may be used to create infrared heating elements include glass, quartz, and ceramics. An electric current must pass through the coils to generate heat using infrared heating elements. When the current passes through the coils, it is met with resistance, and experience to which it responds by generating heat. Upon its generation, the heat is emitted outwards in the form of infrared radiation. As infrared radiation, it conveys thermal energy, i.e. heat, to the items with which its waves come in contact. Infrared radiation, or radiant heat, is a very strong type of heat source because, unlike so many other heat sources, it does not need a secondary medium to convey heat. Rather, it can travel to and be absorbed by surfaces on its own. It can also penetrate liquid materials, solid materials, and gasses alike more easily and completely than convection heating elements. Likewise, infrared heating elements can also penetrate surfaces more efficiently than ultraviolet heating elements, which can only work with the addition of light waves.

Infrared heating elements are known to transfer heat far more effectively and efficiently than other heating elements. They can boast this distinction because when heat is being transferred using infrared heating elements, very little energy is lost to the air. Infrared heating elements are popular for use in heating systems, curing processes, cooking, plastic welding, plastic shrinking, plastic preheating, glass heating, metal heating, and the warm suckling of animals in zoos or at veterinary clinics. In addition, because they do not need to establish direct contact to transfer heat, infrared heating elements are considered of great value to vacuum applications.

Shoppers are afforded various options when it comes to their infrared heating elements. They are available in both standard and custom configurations. Customers may order elements in horizontal orientations or vertical orientations, and they have many choices of caps, including tipped end caps, standard end caps, flat end caps, insert caps, over caps, slotted over caps, notched over caps, tipped insert caps, flat over caps, heavy duty tipped over caps, tipped over caps and tipped long insert caps. All of these caps are available in different sizes, which are typically one inch or under. Individual infrared heating elements are available with numerous tolerances, including electrical tolerances (resistance/wattage, maximum voltage, and maximum amperage), length tolerances (heated length and tube length plus ceramic length), and cold ends. Likewise, they are available with various physical specifications, including their inside diameters, outside diameters, terminations, and lengths.
