Mineral Insulated Band Heaters

Durable Conductive Cylindrical Heating sets Standards for Performance

In the industry today there are numerous construction styles, types, and variations of the band heater.  At Georgia Thermal Products we have concentrated our focus on the two versions that have been tried and true throughout the history of band heaters, this is the Mica and the Mineral Insulated Band Heater.  We know there are numerous options and construction features associated with these units but we have kept our offering simple in order to quickly accommodate your application.

Mineral Insulated Band Heaters

The MI band heater is a high-performance band and its name is derived from its exclusive mineral insulation—a material with a much higher thermal conductivity than mica or ceramic insulators used in other more conventional heaters.

A thin layer of the high thermally conductive Magnesium Oxide material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, “low” thermally conductive layer backs up the element wire while directing the heat inward toward the part being heated.

The result is more efficient heat transfer, which lowers element wire temperatures and increases band heater life.

features and benefits

  • Operating temperatures up to 1400°F (760°C)

  • Watt densities up to 200W/in²

  • Higher heat transfer rates than ceramic or mica bands

Mica Band Heaters

These heaters are our most widely used band heater because of their versatile design and rugged construction characteristics. Mica Bands have sheath temperature capabilities up to 900°F (480°C).  Our Mica Band offering is a proven heater design for good life efficiency and dependability. We maintain the lowest winding temperatures possible, keeping a low-mass heating element assembly for fast heat-up and quick thermal response to controls. 

features and benefits

  • Nominal Watt-Density 20-45 W/in² (3-7 W/cm²)

  • Operating temperatures up to 900°F (480°C)

  • One and Two-piece designs with many construction options
