Construction Overview

In a ceramic band heater, nickel-chrome wire is embedded in a flexible outer wall made of special, interlocking ceramic tiles, which are assembled like a brick wall. A ceramic fiber insulating mat and a stainless steel jacket cover this assembly. This construction minimizes heat loss and reduces electrical consumption by 20%.

Heat is transferred from a ceramic heater to the surface of an application through conduction and radiation. For this reason, a tight grip on the cylinder is not as critical as it is with other other types of heaters. Overtightening should be avoided, since pressure on the insulation mat reduces its insulating efficiency.

Common applications include: injection molding machines; plastic extruders; blow molding machines; container, pipe, and tank heating; and many other process applications.


  • Reduce power consumption
    • An energized ceramic heater will have an outside shell temperature of 350 to 450°F while the inside temperature is maintained at 1200°F. To improve the retention of heat energy, different thickness of ceramic fiber insulation mats are available.
  • Conserve heat
  • High degree of flexibility
  • Uniform heat distribution
  • Various termination styles


Minimum Diameter 2"
Minimum Width 1"
Thickness with 1/4" 5/8"
Standard Gap 3/8"
Maximum Watt Density 45 W/in²
