NF Group 3-15KW EV Heater 400V-800V High Voltage Coolant Heater OEM HVCH
Brief Introduction
In 2025, Nanfeng group pioneered the dual-sided heating technology, launching a new generation of high-voltage electric heaters with a power range of 0-35kW, compatible with 800V high-voltage platforms.
Boasting an industry-leading heating rate and 99% thermal efficiency, our products are widely used in electric vehicles, marine, aviation, and industrial applications—particularly ideal for EV heaters and high voltage coolant heaters.
The core technology utilizes rare-earth thick-film heating elements, printed via precision screen-printing onto stainless steel substrates, enabling highly efficient heat generation. This innovation overcomes key challenges of traditional PTC heaters, such as high-voltage boundary breakdown, ablation, and poor power control accuracy.
Key advantages include:
- High Efficiency: 14% COP improvement, 100x faster thermal response;
- Integrated & Lightweight: 20% fewer components, 28% weight reduction, 22% smaller volume;
- Precision & Reliability: Surge-free precise control, withstands up to 1500V, suitable for demanding high voltage water heater environments.
Protected by multiple patents, our technology ensures a safe and reliable high-voltage heating solution.
