Thin Film Heaters

radiant heater

Thermo-Stone’s heating elements feature a conductive thin film technology applied to the surface of an insulative substrate.  Our advanced film deposition system integrates the heater with the surface of the substrate resulting in a very robust, responsive and uniform radiant heater

Thermo-Stone’s thin film technology allows the heater to cover a larger surface area than traditional heating technologies, reducing the number of hot and cold areas on the heated surface.  This greater coverage allows the thin film heater to heat up faster, use less energy, run at a lower temperature, and have better uniformity.  Thermo-Stone’s thin film heaters also have very low mass allowing for very quick heating and cooling cycles.
