Super PTC Heaters

Automatic temperature control and excellent product durability.

PTC curve is a unique characteristic of heater with carbon paste,

and it means that the resistance will rise if the temperature is

overheated, allowing to control the temperature on its own.

Positive Temperature Coefficient Resistance Graph


Suntech’s heater uses PTC Characteristic-resistance increases as the temperature increases. Thus, when connected to electricity the eater ad can control and maintain temperature itself without any other system along with condition.
