Types of Strip Heaters
Heaters from leading manufacturers, such as Watlow or Tempco deliver the benefits of advanced construction techniques. They offer high-temperature, high-watt density capabilities, with sheaths made from corrosion resistant materials. Our top heaters include: channel, mineral insulated, mica insulated, ceramic insulated and finned strip heaters for efficient air or surface heating.
- Mica: These heaters feature a high temperature oxidation metal sheath and high grade mica insulation resistant to moisture and high temperatures. Nickel/Chromium resistance wire evenly wound provides for uniform and reliable heat distribution. These heaters also are versatile because they come in many shapes, sizes and termination options which channel heaters do not. Also mica heaters can be manufactured with holes in them to fit your needs. The temp that these heaters can withstand is up to 900F.
- Mineral Insulated: The MI heater is a thin, responsive heater that uses the most advanced heater construction techniques. A nickel-chromium element wire is embedded in it. Mineral insulated heaters are medium heat heaters and are mica strip heaters. These heaters can withstand temperatures reaching 1400F.
- Channel: Channel Heaters consist of a helically wound resistance coil evenly strung through specially designed ceramic insulators. These heaters can get extremely hot; however, they come in one width and one shape. The channel heater can withstand 1100F and is still extremely durable.
How to Choose a Heater
Many factors can influence the type of heater that is optimal for your application. Some of the many specifications that you will need to consider include:
- Physical dimensions – Strip length, width or thickness
- Power requirements and electrical outputs – Watt density, maximum operating temperature and AC voltage
- Features – Coil patterns, enclosed sides, corrosion-resistance, open elements, instrumentation cutouts
- Termination types
- Opposite end posts have a post at both ends of the heater
- Tandem posts are located in-line along the length of the heater
- Parallel posts are positioned in-line along the width of the heater
- Three-post terminals have a single end post on one end and two at the opposite end
- Horizontal leads are placed along the length of the heater
- Terminal box connections have an enclosure on the surface of the heater
- Insulated leads
- Metal braided leads
- Flexible conduit leads
Depending on your particular application you may find that flexible heaters, coil heaters, stainless steel strip or ceramic heaters could be the most suitable option.

Strip heaters, aka component heaters, can be bolted or clamped onto solid surfaces to provide heat over a large area. They also have fins that allow them to maximize the heated surface area and to increase heat transfer. Their unique and versatile design make them great for most surface heating and process air heating applications.
Many manufacturers use these heaters for:
- Extruder Barrels
Hi-Watt carries a wide array of strip heaters from industry-leading manufacturers, including Tempco and Backer Marathon. Whether you’re purchasing a mica, channel, or mineral-insulated strip heater, you’ll always get reliable, uniform heating.
Some of the benefits of our strip heaters include:
- Easy Installation: Our strip heaters are easy to modify and mount to your equipment.
- High Operating Temperatures: While the resistance varies by design, mica, channel, and mineral-insulated heaters have high operating temperatures.
- Fully Customizable: When you purchase a heater from Hi-Watt, we always provide solutions designed for your specific applications. Customizable features include strip length, width, and thickness, termination types, and power and electrical output requirements.
- Versatility: As we previously mentioned, strip heaters have incredibly versatile designs that make them suitable for a wide array of applications.
Heater Element for Maximum Heat Transfer
Each heater model will have its own maximum sheath temperature, watt density and voltage specifications. Hi-Watt offers units with the heater elements reliably housed for maximum transmission.
Mica, mineral, ceramic and other industrial grade insulators manage heat losses. Plus, a variety of top quality sheath materials are used. Our channel heaters feature a resistance coil that’s evenly wound through ceramic insulators. Our mica heaters also have evenly wound wire for uniform heating. A mineral insulated (MI) heater is another versatile option with its thin size and advanced construction.
Strip Heaters From Hi-Watt
You can transmit heat to a flat area fast by installing industrial heaters that provide uniform heat transfer. Our finned heaters are the models you need for air transmissions. Industrial heater applications range from surface heating of molds to process air heating for ovens. We’ll deliver top technology in your heater. Choose from low-mass designs, fast heat-ups, and clamp or bolted installation. Then, rely on our Hi-Watt technical expertise.
