FAQ

Q: How to choose the right PTC water heater?
A: Please provide the following parameters to help with selection:

· Application scenario (bus / heavy-duty truck)

· Intended use (battery heating, cabin heating, regenerative braking energy recovery)

· Operating conditions

· Operating voltage range

· Rated voltage and power

· Battery type and capacity

· Target outlet water temperature

· Ambient operating temperature

· Coolant flow rate

· Installation space

Q: How does a PTC water heater work?
A: The PTC heater works by passing electric current through PTC ceramic material. The material’s resistance increases as temperature rises, automatically adjusting the heating power to maintain a constant temperature.

Q: Which vehicle types is it suitable for?
A: Suitable for most electric buses, electric trucks, and electric construction machinery (excavators, loaders, etc.).

Q: How does it perform in low-temperature environments?
A: PTC heaters remain stable in low-temperature conditions, making them ideal for electric vehicles in cold regions.

Q: What are the core advantages of EVLINK PTC water heaters?
A: High reliability, fast and uniform heating, patented thermal expansion control, moisture protection, and exceptional performance under extreme conditions.
