The main purpose of PTC car heater is absorbed the cold air and output hot air after heating. This product has the ease installation, energy efficiency, compact appearance and so on other characteristics.

  Compared other heaters, PTC heater has the following advantages:

1. Save energy

 Compared with heating pipes and heat resistance products, PTC heater has its own characteristics on the material itself, they regulate their own thermal power output according to changes in environmental temperature, so it can optimize the power consumption to a minimum, while with high heat efficiency materials also significantly enhance the utilization efficiency of energy.

2. Safe

 PTC heating temperature will always  below 280C, so it will never have redness, open flames and other phenomena, causing burns, fire and other safety hazards. With a very high security.

Long Life. Heater can work continuly for about 10000 hours, while the power attenuation <10%, no significant decline in the output power

 3. Self-Controlled temperature

Rapid heating, even can self-controlled when fan is falied

4. Wide working voltage range  

Can be designed between 12V-460V according to the requirement, for example, the rated voltage is 380V, but the actual voltage at 300-400V, it will not cause too much difference to the power output.

Positive temperature coefficient (PTC) heaters bring efficiency and safety to EV heating systems. The heating element inside a PTC heater has a positive temperature coefficient and its resistance increases with temperature. When power is first applied to the cold PTC heating element, it has a low resistance and draws a large amount of current. As it heats up, the resistance increases and the current draw decreases. This makes a PTC heater inherently both safe and efficient; the PTC heater will stop drawing current if it overheats and it only draws the current it needs to maintain temperature. A PTC heater also heats faster than a traditional element, as it draws maximum current when it is cold.
