NF High Voltage Coolant Heater for CE Certificate


This PTC electric heater is suitable for electric / hybrid / fuel cell vehicles and is mainly used as the main heat source for temperature regulation in the vehicle. The PTC electric heater is applicable to both vehicle driving mode and parking mode. In the heating process, electric energy is effectively converted into heat energy by PTC components. Therefore, this product has faster heating effect than internal combustion engine. At the same time, it can also be used for battery temperature regulation (heating to working temperature) and fuel cell starting load.

| Medium type | Water:ethylene glycol/50:50 |
| Low voltage operating voltage/v | 9V-32V |





Due to its low thermal mass, the coolant heater has a high thermal power density with short response times. As a result, the technology draws less power from the battery than from comparable systems, resulting in an increase in range for purely electric driving. In addition, the technology generates comfortable vehicle interior temperatures within a very short time.
The main advantage are as follows:
1.Compact structure, high power density, can be flexibly adapted to the vehicle installation space.
2.The plastic shell can achieve thermal isolation from the frame, so as to reduce heat dissipation and improve efficiency.
3.The redundancy seal design can improve the system reliability.
