Mica Band Heater

Mica band heater, Mica band heaters offer efficient and economical heating solutions to pipes and tubes that require external indirect heating. These heaters are used to heat-up the external surface of drums or pipes for a gradual heat transfer. A mica core surrounds the precisely wound heating element, producing a thin, efficient heater. The mica core is enclosed in a continuous corrosion resistant sheath and formed. All full mica band heaters are designed with closed ends to protect against contamination. The maximum sheath temperature is 800°F and is used mainly in plastic industry. Terminal boxes can be provided that protect terminations and also have the option of temperature controllers to help regulate applied heat. Mica is used as it provides exceptional insulation, dielectric strength and heat transfer capability for long heater life. Insulation is required to direct the heat to the application, avoid heat loss and slow heat-up time.
