Thermo-Stone's thin film heating element features a conductive thin film 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 uniform radiant heater.
Radiant heating is achieved by "spreading the energy" evenly over the substrate. The entire surface becomes the active heat source which transfers energy more effectively. Thin film heating allows for lower watt density and less power for improved energy efficiency. Various proprietary formulas and processes are used to control the resistance value of the element to meet the requirements of the application. Thermo-Stone heaters have low thermal inertia for fast heat response and more accurate temperature control.
Safe
- Lower temperature requirement
- No ignition points
- No red-hot burn points
- Acid resistant
- Accurate temperature control
Powerful
By spreading the energy evenly over a surface, watt density and heat are lowered to reduce stress and demand loads.
- Rapid heat response
- Up to 800 watts per square inch (depending on application)
- Operates up to 500°C or more depending on application
- Radiant even heat
- Delivery of power at lower temperatures
- Low thermal inertia for a gas-like fine tuning
Flexible
- Flat panels - coat one or both sides
- Optically transparent heat generating surfaces
- Louvered panels
