Positive Temperature Coefficient

What is PTC?

PTC Element Fan Heating

PTC ceramic heating elements improve the efficiency of typical resistive heating elements used in applications where electrical forced-air heating is required. The PTC, Positive Temperature Coefficient, the heating element is built into extruded aluminum profiles combined with a fan to effectively transfer heat quickly to an adjoining space.  Aluminum profiles are designed for optimal heat transfer with the forced air across the fins.

Efficient Transfer of Energy

In any heating application, some form of energy, electrical, gas, oil, or even hydropower is being converted into heat.  The energy of one is converted to heat energy which in turn raises the temperature of the adjoining air or physical object to bring both into equilibrium.

A PTC fan heating system converts electrical energy through the resistive element to heat which transfers very effectively to the aluminum housing.  The aluminum housing is designed to radiate the heat to the air moving across its surfaces.

Why Use PTC Ceramic Heating Elements?

PTC Ceramic Heating Elements are Unique in Industrial Heating.


Industrial heating brings to mind huge furnaces, pouring hot lava-like metal, and long annealing ovens, but there is another subset of heating elements not talked about as often.
