Tube Heaters

Thermo-Stone’s patented Tube Heater Technology (#6,376,816) allows for applying a thin film coating directly on the surface of a non-conductive tubular substrate.Thermo-Stone’s thin film technology allows for a larger heated area, when compared to standard heater technology, which eliminates hot and cold spots.This feature allows for tighter temperature controls and lower power consumption.

Product Specification Range:

Temperatures up to 450°C
Dimensions - Tubes up to .60" OD
Voltages - From 3 volts to 300 volts - AC or DC current
Wattage - Up to 700 watts/sq in. (Depending on substrate and design configuration)

Available Substrate:

Porous Ceramic
