Overview
SmartHeat is the ideal solution for many of today’s most 
demanding heating applications. It provides a plug-and-play 
heating solution requiring only a power source. Each heater 
operates to a specific temperature and power based on its 
unique design. The heating power is applied and modulated 
at infinite points across the entire heating surface based on 
the heat load. This allows the heater to provide the required 
power, up to but never exceeding the designed temperature.
SmartHeat Technology
SmartHeat™ technology consists of a thin silicone matrix 
loaded with conductive carbon particles. Electrical current 
moves between the carbon particles via quantum tunnelling 
of electrons through the non-conductive silicone material. The 
spacing of the carbon particles determines electrical resistance 
of the material and the current it can carry at any point. 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 designed set-point temperature 
the heater effectively becomes an electrical isolator, drawing 
negligible current, and no longer producing heat. Conversely, 
if the silicone cools via environmental or load variations, the 
carbon particles pull closer together, reducing resistance. 
This allows a localized current-flow increase and the heater 
produces more heat at that location in order to maintain 
thermal equilibrium.
These effects drive the self-limiting nature of this technology 
without the need for external instrumentation and control 
systems. By controlling the composition of the carbon-silicone 
matrix in production, the the heater is designed to approach, 
but not exceed, a specific temperature set point. When a 
heater is powered, it warms to its designed set point and 
maintains that temperature within a narrow band.
