PTC Air Heater

PTC Air Heater

Self-regulating function of power in correlation to the air volume flow and ambient temperature.

The power and the temperature can be easily adjusted by varying the speed of the fan that blows air over the radiator.  Also its power characteristics will change with changes in ambient temperature, When the ambient temperature decreases, the power increases. When the ambient temperature increases, the power is reduced.

Heating Power Characteristics of PTC Air Heater
