High-voltage electric PTC water heaters are widely used in pure electric commercial vehicles. Their high efficiency, rapid heating, safety, and reliability have set them as the new standard for heating in pure electric commercial vehicles.
Fast heating: Compared to traditional heating methods, high-voltage electric PTC water heaters can heat the coolant to the appropriate temperature in a fraction of a second, typically within just a few seconds to tens of seconds, truly achieving "instant warmth." For example, in extremely cold winter weather, after starting the vehicle, high-voltage coolant heaters can quickly activate, allowing drivers to enjoy a warm driving environment without waiting.
Energy-saving efficiency: Due to the automatic temperature-limiting feature of the PTC thermistor, once the set temperature is reached, the resistance increases, the current decreases, and energy consumption is reduced, avoiding unnecessary energy waste. Furthermore, the high voltage drive system improves heating efficiency. Compared to low-voltage PTC heaters, at the same heating power, electric water heaters can operate at a lower current, further reducing energy consumption and minimizing the impact on vehicle range. Safe and Reliable: PTC thermistors offer excellent stability and safety, and their automatic temperature-limiting function effectively prevents overheating. High-voltage PTC water heaters are also typically designed with multiple safety features, such as overvoltage protection, overcurrent protection, and short-circuit protection, ensuring safe operation under various operating conditions and providing reliable heating for vehicle owners.
Widely Applicable: Whether it's a small pure electric sedan, a large pure electric SUV, a new energy light truck, a new energy heavy truck, or a new energy bus, Nanfeng Group's high-voltage PTC water heaters can be customized to suit different vehicle models and battery systems. They also operate stably in a variety of ambient temperatures, providing reliable heating for pure electric vehicles from the extreme cold of northern China to the humid and cold conditions of southern China.
Nanfeng Group independently develops and produces a variety of PTC heater models (1-6kW, 7-20kW, and 24-30kW HVH heater), widely used in new energy commercial vehicles, fuel cells, and other fields. If you need PTC heaters, Nanfeng Group is undoubtedly a trustworthy choice. Nanfeng Group also develops and produces low-temperature thermal management systems, providing battery thermal management system solutions for new energy vehicles that experience reduced battery performance in winter.
