There are three main types of these heaters that differ by material: mica, ceramic, and mineral insulated. They come in various sizes and each brings their own strengths to the table. These are sometimes further subdivided based on the following factors:

  • Performance specifications
  • Sheath material or sleeve
  • Termination type
  • Dimensions
  • Mounting
  • Insulation

Mica Band Type Heaters

For less intense temperatures, mica insulation offers competitive dielectric strength and corrosion resistance. The maximum temperature is lower, typically around 900 degrees Fahrenheit, but the water and chemical resistance make them popular in harsh environments.

Mineral Insulated Heaters

Mineral-insulated band heaters derive their name from the unique mineral-based insulation they employ. This insulation material exhibits significantly higher thermal conductivity than traditional options like mica and ceramic. The exceptional thermal conductivity allows these heaters to achieve maximum temperatures of up to 2,000 degrees Fahrenheit, catering to the most demanding heating requirements. In addition, their superior heat transfer capabilities ensure enhanced overall efficiency.

Ceramic Band Type Heaters

Ceramic band type heaters are heaters that can handle extreme temperatures, typically up to 1,400 degrees Fahrenheit. The excellent insulation of a ceramic segment helps you focus the heat where you need it, but the insulation also retains heat for longer, making overheating an issue. Ceramic bands reduce operations costs and energy consumption. They can sustain temperatures as high as mineral insulated heaters, but the outside temperature remains low. Thus, there is less wasted heat. For increased efficiency, you may also consider double-insulation options. To make this genius engineering possible, manufacturers construct these bands out of stainless-steel housing and then stack ceramic tiles on the inside. To add to this, they are built to last and easy to install. Finally, they also offer more termination options than mica and mineral insulated options. These include the following:

  • Termination box
  • Euro connectors
  • Fiberglass lead
  • Post terminals

Watlow 

With over 450 patents, Watlow® products find applications in defense systems, medical equipment, pharmaceutical processes, industrial manufacturing, and chemical processes. Additionally, Watlow® specializes in designing complete thermal systems for clinical equipment, food service equipment, semiconductor processes, and energy and environmental technologies. 

Mineral Insulated (MI)

The MI band heater is a high-performance heater that utilizes Watlow’s exclusive mineral insulation, providing higher thermal conductivity than traditional heaters using mica and ceramic insulators. It consists of a layer of highly conductive mineral material for electrical insulation. In contrast, a thicker layer directs heat toward the target, resulting in efficient heat transfer, lower wire temperatures, and increased heater lifespan.
