Heating Elements the Backbone of Heating Technology

 

In today's fast-paced world, we rely on numerous technological advancements to simplify our daily lives. Among these innovations, Heating elements stand as unsung heroes, quietly working behind the scenes in various household and industrial appliances. At Airex, we believe that understanding the intricate workings of heating elements can help you make informed decisions about your heating needs while keeping an eye on heating element prices.

 

What Is a Heating Element?

 

A heating element is the heart of any heating appliance, whether it's an electric stove, water heater, or industrial furnace. Essentially, it is a vital component responsible for generating the required heat. These elements are often crafted from a heating element coil, which is a meticulously designed wire that can withstand high temperatures and resist corrosion.


 

Different  Types of Heating Element

 

The complete heating system is not made up of the heating element. A heater also includes insulation, packing, sheath, terminations, leads, seals, and the heating element. To fit a particular purpose, these heaters come in a variety of shapes and combinations. The most popular heaters and their uses are listed below.


 

Heaters for Air Process: As the name implies, these heaters are used to warm air in motion. The fundamental structure of an air process heater is a heated tube or pipe with a cold air intake at one end and a hot air exhaust at the other. Coils of heating elements that are insulated by ceramics and non-conducting gaskets run the length of the pipe. Applications requiring high flow and low pressure often employ them. Heat shrinking, laminating, adhesive activation or curing, drying, baking, and other processes can all be done with air process heaters.


 

Cartridge Heaters: In this category of heater, a ceramic core, commonly formed of compressed magnesium oxide, is wrapped in a resistance wire. There are other rectangular variants where the resistance wire coils cross the cartridge three to five times. For optimal heat transfer, the resistance wire or heating element is placed close to the sheathing material's walls. The sheath is often composed of corrosion-resistant materials like stainless steel to protect the internals. Typically, the leads are flexible, and one end of the cartridge houses both of their terminations. Die or mould heating, fluid heating (immersion heaters), and surface heating all require cartridge heaters.


 

Tubular Heaters: The internals of a tubular heater are identical to those of a cartridge heater. The lead terminals are on the tube's opposing ends, which distinguishes it most from cartridge heaters. The entire tubular structure may be bent into different shapes to provide the type of heat distribution needed for the room or surface being heated. In order to improve heat transfer, these heaters may also have fins that are mechanically connected to the sheath surface. Cartridge heaters and tubular heaters are utilized in a variety of applications and are equally flexible.

 

Band warmers: These warmers are made to wrap around cylindrical metal surfaces or containers, such as pipes, barrels, drums, extruders, and so on. They have bolted locking tabs that firmly clamp to the container's surface. The heater is a thin ribbon or wire of resistance that is located inside the band and is normally protected by a mica layer. Brass or stainless steel is used for the sheathing. Utilizing band heaters has the additional benefit of indirectly warming the fluid inside the vessel. This indicates that no chemical attack from the process fluid is made on the heater. When utilized for oil and lubricant servicing, potential ignition is also avoided.

 

Strip Heaters: Bolted to the surface being heated, this sort of heater is flat and rectangular in shape. Internally, it resembles a band heater. Ceramics like magnesium oxide and fiberglass can also be used as insulators in addition to mica. Strip heaters are often used to surface-heat dies, molds, platens, tanks, ducts, etc. Due to their finned surfaces, they can be utilized for fluid or air heating in addition to surface heating. Ovens and space heaters both use finned strip heaters.

 

Etched Foil Heaters: Thin-film heaters are another name for etched foil heaters. In this kind, a foil, often composed of aluminum, is etched, then the resistive heating substance is attached to it. The substrate can alternatively be composed of heat-resisting synthetic rubber or thermoplastic polyurethane (TPU) if greater flexibility and tear resistance are needed. The heating components' close proximity to one another is another benefit in addition to flexibility. This is the photochemical etching's intrinsic benefit. In such tiny structures, a greater heat density may be distributed uniformly. In compared to standard wire heaters, it has more specific uses. Etched foil heaters are often used in textiles, electronics, medical equipment, and instrumentation. 

 

Ceramic heaters- often overlooked but integral to many heating applications, utilise ceramics with remarkable properties. These ceramics exhibit a high melting point, thermal stability, temperature strength, chemical inertness, and low heat capacity, making them an excellent choice for efficient heat transfer. However, it's essential to distinguish ceramic heaters from ceramics used as insulators. In this discussion, we delve into the unique characteristics and applications of ceramic heaters, including notable materials like silicon nitride and aluminum nitride, as well as the intriguing world of ceramic heaters.
