NF Group High Voltage Coolant Heater 10KW HVCH 800V EV Coolant Heater
A thin‑film heater designed for new energy vehicles is a next‑generation high‑efficiency electric heating device manufactured using semiconductor‑derived processes. It is increasingly regarded as a key technology to replace conventional PTC (positive temperature coefficient) heaters.
The core principle involves using physical vapor deposition (PVD) and other semiconductor techniques to precisely deposit multiple functional layers onto an ultra‑thin substrate, forming a precise and highly efficient resistive heating layer.
Recently, Nanfeng Group has launched a 10 kW thin‑film heater series. We warmly welcome inquiries from both new and existing customers.

NF 7-10KW 800V High Voltage Thin Film Coolant Heater
The thin-film heater for new energy vehicles represents a next-generation electric heating solution characterized by exceptional power density, thermal responsiveness, and energy efficiency. Fabricated using semiconductor-grade physical vapor deposition (PVD) and complementary thin-film processing techniques, it enables precise, nanoscale control over the composition, thickness, and sheet resistance of multi-layer functional stacks deposited onto ultra-thin, thermally stable substrates. This architecture yields a highly uniform, low-mass resistive heating element with superior spatial temperature uniformity and rapid thermal transient response—establishing it as a technically viable and increasingly adopted alternative to conventional ceramic PTC heaters in high-voltage EV thermal management systems.
Nanfeng Group has recently introduced its 10 kW thin-film heater series. Technical specifications, qualification reports, and application support are available upon request for qualified OEMs, Tier 1 suppliers, and system integrators.

NF Group 10KW 800V High Voltage Thin‑film Coolant Heater HVCH EV Coolant Heater
Think of our thin-film heater as the next-gen upgrade for EV heating—it’s a super-thin, high-efficiency electric heater built using advanced semiconductor-style manufacturing. Many engineers now see it as the natural replacement for traditional PTC heaters.
Here’s how it works: instead of bulky coils or ceramic elements, we use precision techniques like physical vapor deposition (PVD) to “paint” ultra-thin, multi-layer heating films onto a lightweight substrate—kind of like making a microchip, but for heat. The result? A heating layer that’s both incredibly accurate and highly efficient.
By the way—we’ve just launched our new 10 kW thin-film heater series. Whether you’re working with us for the first time or you’re a long-time partner, we’d love to hear from you and walk through what makes this heater a great fit for your project.
