NF Group 350V 7KW CAN Control PTC Coolant Hearter

The NFW09 PTC coolant heater is primarily designed for heating the passenger compartment, defrosting and demisting windows, as well as preheating the power battery. It complies with the relevant regulatory and functional requirements.
The main functions of the high voltage coolant PTC heater include:

- **Control Function:** The heater operates in either power control mode or temperature control mode;
- **Heating Function:** It converts electrical energy into thermal energy;
- **Interface Functions:** It supports energy input for the heating and control modules, signal module input, grounding, and water inlet and outlet connections.

Key performance characteristics of the high-voltage coolant heater (HVCH) are as follows:

- It features a compact structure and high power density, enabling flexible adaptation to the installation space of the vehicle;
- The use of a plastic housing achieves thermal isolation between the housing and the frame, thereby reducing heat loss and improving thermal efficiency;
- A redundant sealing design enhances system reliability.
