Thermavance™

Promethient’s Thermavance™ system allows for the cooling and heating of a person via direct thermal conduction. Heat is pumped from the person, cooling them, or heat is pumped to the person, warming them. Thermavance is a patent pending system that was developed by Charles Cauchy, an internationally recognized expert in thermoelectric device design, manufacturing and applications. Thermavance combines solid state heat pumping provided by a thermoelectric device and couples it with thermally conductive, flexible and lightweight graphene.
Solid state heat pumping is accomplished with a specialized semiconductor called a thermoelectric device, or “TED.” TED’s use the flow of electrons to create the Peltier Effect within the semiconductor. The Peltier Effect is created at the junction of P and N type semiconductor elements that are laminated between two ceramic plates. With the application of a voltage and the flow of current, one plate will heat and the opposing plate will cool. When the polarity of the applied voltage is reversed, the heat flow will reverse.
