Rectangular/Square Heaters

Thermo-Stone’s thin film technology allows designers to develop heaters with nearly 100% heater coverage.This coverage allows the heat and power to be spread over the entire heater surface, eliminating hot and cold spots.This even heat allows for faster response, more even heat distribution and lower power consumption.By integrating Thermo-Stone's patent, “Structure and Method to Compensate for Thermal Edge Loss in Thin Film Heaters” (#7,025,893), designers can further improve uniformity by eliminating cold areas caused by edge loss.
