Products Details






Key advantages (compared to single PTC / single water heating)
▇ Strong adaptability to extreme cold: can work normally at -25℃, solving the problem of slow start-up of single water heating systems.
▇ Energy optimization: Automatically switches to water heating after the water temperature rises, saving 30%–50% more electricity than a single PTC system.
▇ High defrosting efficiency: Dual heat sources reduce defrosting time by over 40%.
▇ Safe and reliable: PTC self-limiting temperature protection, high voltage insulation protection, anti-dry burning, and anti-leakage protection.
▇ High integration: Integrated design, small installation space, simple piping, and convenient maintenance.
Products Application
New energy buses, new energy heavy/light trucks, and high-end passenger vehicles.
