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 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.

 

 

• (1) The model is compact, the electric power is high and can be adjusted for the installation of all vehicles.

• (2) The use of a plastic cover helps isolate the space between the case and the frame, reducing heat generation and increasing efficiency.

• (3) Designing redundant seals can increase system reliability.

 

 

 

 

 

This product uses vacuum compression packaging, which isolates the electric heater from the air and can better ensure the cleanliness of the inside of the electric heater. Customers who have high requirements for the cleanliness of the electric heater can use this type of packaging.

 

NF electric heaters are CE certified and have undergone DV tests, water resistance tests, EMC tests, etc., so their quality is guaranteed.

 

 

 

1. Q: What is a PTC water heater, and how does it work?
A: A PTC (Positive Temperature Coefficient) water heater uses ceramic elements that self-regulate temperature. As the coolant flows through the heater, the PTC elements heat it, providing warmth to the vehicle's cabin or battery system.

2. Q: Why is my 5kW PTC heater not producing enough heat?
A: Possible causes include a low coolant level, air pockets in the coolant loop, a faulty thermostat, or insufficient electrical supply. Check coolant levels and ensure the system is properly bled.

3. Q: Does the 5kW PTC heater drain the vehicle's battery quickly?
A: At full power, a 5kW heater can consume significant energy. However, most systems modulate output based on demand. Preheating while charging or using eco-mode can reduce battery drain.

4. Q: What should I do if the heater fails to start?
A: Verify power supply (e.g., fuse, relay, wiring), check for error codes, and ensure coolant temperature sensors are functioning. Restart the system or consult a technician if issues persist.

5. Q: How often does the PTC heater require maintenance?
A: Routine maintenance includes checking coolant quality, ensuring electrical connections are secure, and inspecting for debris in the coolant loop. Follow the manufacturer's service schedule.

6. Q: Why is there noise during operation?
A: Gurgling sounds may indicate air in the coolant system. Clicking noises from relays or pumps are normal. Persistent abnormal noises warrant inspection for pump or valve malfunctions.
