PTC Air Heaters

PTC Air Heater utilizes state-of-the-art Positive Temperature Coefficient (PTC) ceramic heating elements.

This technology offers rapid heating with low air resistance, ensuring efficient and uniform warmth distribution throughout the desired area.

The PTC heat output can be regulated by the airflow applied in typical applications of heat generation. The higher the airflow, the higher the heat output and power(wattage).
