Heating Element Types

Heating element varieties used in industrial, commercial and consumer applications include: immersion, quartz, flexible, infrared, wire, ceramic, electric, metal-based and composite heating elements, among many others.

Immersion Heating Element
Immersion heating elements are used to heat gases and liquids; they have the special ability to be immersed in the materials they heat without malfunctioning. Immersion heaters are further characterized by their fast, efficient and cost-effective heating solutions. Types of materials they typically heat include plating baths, mild acids, oils, water, salts, air, and chemical solutions. Immersion heating elements are primarily with systems like: process systems, boilers, water heaters, heat transfer systems, oil heaters, and storage tanks.

Quartz Heating Element
Quartz heating elements convert electrical currents into infrared rays by running them through special resistors. In doing so, they provide rapid heating. These fast process speeds make them very popular for use with industrial applications like film curing, thermoforming, powder coatings, adhesive sealing, and paint drying, as well as zone control applications in automotive, print, petrochemical, textile, glass and electronic industries.

Flexible Heating Element
Flexible heating elements are able to bond to a variety of compounds and shapes and provide direct heating. This versatility is possible because they are very thin and bendable.

Infrared Heating Element
Infrared heating elements emit heat in the form of infrared waves, which are a type of electromagnetic radiation known for transferring heat efficiently. Infrared heating elements are used in conjunction with radiating heaters like duct, immersion, and tubular heaters, which heat air or liquid on the large scale. They support industrial ovens, pressure vessel heating, storage tank heating, boilers, water treatment plants, steam generation and more.

Wire Heating Element
Commonly, heating elements, whatever their type, are found in the form of coils or wires. In fact, wire heating elements are among the most widely used heating elements for industrial and commercial drying. To make them, manufacturers map them out with wire diagrams. They are found in surface treatment heaters, kilns, and many other dryers.

Ceramic Heating Element
Another type of heating element, the ceramic heating element, is utilized in convection heating; ceramic elements are built into space heaters, furnaces and semiconductors. There are several types of ceramic heating elements, including molybdenum disilicide and PTC.

Molybdenum Disilicide Element
Molybdenum Disilicide is a material that shows the characteristics of both a metal and ceramic. With an extremely high melting point, (to be precise, 3690 º F), it is considered ideal for a number of high-capacity heating elements, used across industries, including the glass manufacturing.

PTC 
PTC, which extends to positive thermal coefficient for resistance, is a high-profile ceramic material that is utilized in automotive rear-window defrost heaters, space heaters and expensive hair dryers. There is also available polymer based PTC ceramics that are used in many purpose-built heaters. These elements increase the heating as their resistance is amplified. Controlling the heating of these elements is simple, that is because they are the selection for self-regulating electric heaters.

Electric Heating Element
Electric heating elements are quite prevalent as well, especially in the service of industrial electric heaters.

Cartridge Heater
Cartridge heaters supply localized heat to equipment parts in metal fabricating, foam fabricating, plastic fabricating, food processing and packaging.

Metal-based Heating Elements
As the name suggests, metal-based heater bodies are composed primarily of metals. Because metal is generally such a good conductor of heat and electricity, metal-based elements make one of the most effective heating elements. They are used in everyday and industrial appliances alike. They can be classified in many subtypes, including nichrome-based heating elements and resistance element wire based heating elements.

Nichrome Heating Element
A large number of electric heaters have elements made of nichrome, which is an alloy made up primarily of nickel and chrome. Nichrome based heaters use alloys of 80% nickel and 20% chromium.

Resistance Wire Heating Element
Some metal-based parts are composed by a set of high resistant wires and ribbons. These wires can be sometimes straight or coiled, as per the design and heating capacity of the appliance. These wires are used as resistance. The applications, in which you can find such provisioning, are toasters and handheld body massagers. Kanthal, nichrome and cupronickel are a few most used metals in the conception of resistance wires.

Coil Heater
Coil heaters, band heaters or strip heaters help extruding channels and hoppers maintain the plasticity of materials as they are being extruded.

Composite Heating Elements
Composite heating elements are heating elements made up of a mixture of metallic and ceramic materials. These heating elements are available in many types, including, among others, tubular elements, radioactive elements and removable ceramic core heating elements.
Tubular Heating Element
Tubular elements are basically metallic tubes that have a thin coil of nichrome, which heats up the application. Named for their tubular shape, tubular heating elements are found in ovens, dishwashers and more. They may be manipulated into a standard shape or they may be take on a custom shape for a specific application.

Radioactive Heating Element
Radioactive elements, also known as heat lamps, are high powered incandescent lamps that primarily radiate infrared waves, not visible light. Most often, they’re used in radiant space heaters and many types of food warmers. They come in two main styles: tubular and R40 reflector lamp. Reflector lamp heating elements come in a few main styles: gold coated, ruby red coated and clear.

• Gold coated lamps feature a deposited gold dichroic film on the inside. This reduces visible light and lets through the majority of the short and medium infrared waves. These are primarily used to heat people.
• Ruby coated lamps have the same function as gold coated lamps. They are much less expensive than gold coated lamps, but they permit a much stronger visible glare.
• Clear lamps have no coating, and are used primarily in industrial production processes.

Removable Ceramic Core Element
These heating elements are made up of coiled resistance wire threaded through one or more cylindrical ceramic segments that may or may not feature a center rod. They work when inserted into a metal tube or sheath that is sealed at one end. Because of this, users can replace or repair removable elements easily, without fear of breaking anything. Usually, they’re used to heat a fluid under pressure.

Carbon Fiber Composite Element
These heating elements are made up of a combination of carbon fiber and a resistive material like nickel, a thermoset like epoxy or a thermoplastic like PEEK. Carbon fiber composite elements are generally corrosion resistant, extreme temperature resistant and lightweight. They’re often used in aircraft de-icing, consumer heating and industrial heating.
