SmartHeat SLT™ Thin-film Heaters Thermostatic Control at the Molecular Level

SmartHeat SLT™: Temperature Control Was Never this Easy Temperature is critical to a variety of mechanical, chemical, and biological processes. From the cold of space to the halls of a modern hospital, developers build in heating to keep products and systems running properly. SmartHeat SLT™ uses a patented polymer compound to produce a thin film heater that controls temperature without external sensors or controllers. SmartHeat SLT: Simple, Stable and Safe SmartHeat is the ideal solution for many of today’s most demanding heating applications. It provides a plug-andplay heating solution...

Polymer resistance increases to reduce power draw as target temperature is reached. Safety SmartHeat is self-limiting, meaning it can never exceed the designed safety temperature. This is particularly important in applications in which overheating can damage equipment or impair the operation of the system. It prevents damage due to heater delamination or drastic changes in environmental heat loads. If a heater becomes delaminated, a traditional heater would over-temp and either create a hot spot or drive to failure. The SmartHeat material on the other hand will simply lower the power output...

How it Works SmartHeat SLT consists of a thin silicone matrix loaded with conductive carbon particles. Electrical current moves between the carbon particles via quantum tunneling of electrons through the non-conductive silicone material. The electrical resistance of the material and the current it can carry at any point is determined by the spacing between the carbon particles, and that the spacing changes with temperature. As the silicone warms, thermal expansion drives the carbon particles farther apart and increases resistance point-by-point over the surface of the heater. At the...
