Ceramic Band Heaters

Zesta Ceramic Band Heater
Zesta Ceramic Band Heater
Zesta ceramic band heaters are designed for high-performance.  With maximum barrel temperatures to 1400°F (760°C), ceramic band heaters can deliver high temperatures with energy efficiency.  Built-in thermal insulation minimizes heat loss, and conserves energy.

A variety of heater constructions are available, with a selection of termination and clamping options.

For specialized variations, please consult your Zesta sales engineer for custom applications.
