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
