High Voltage Water Heater 7KW

The electric PTC Heater Module comprises a PTC heater assembly, a control and internal pipes. The heated component is installed in an aluminum die casting, creating a sealed recirculation tube with a plastics housing, where the coolant flows through the heater body in a sinuous structure.

And four sets of PTC components (PTC_A, PTC_B, PTC-C, PTC-D), forming four high-voltage heating branches that can be independently powered on or powered off for control. By combining them, stepwise power regulation control can be achieved.

1. Rapid Heating and High Thermal Efficiency

Utilizing PTC ceramic heating technology, it provides stable heat output, rapidly heats the coolant, and simultaneously heats the entire vehicle cabin and preheats the power battery. It boasts low heat loss and outstanding heating efficiency.

2. Wide Voltage Compatibility and Strong Versatility

Supports DC 450V-750V wide voltage operation, perfectly adaptable to various vehicle types including new energy buses, commercial vehicles, and engineering vehicles, offering broad installation compatibility.

3. Multiple Protections for Safe Use

Built-in multiple safety protections including over-temperature, over-current, over-voltage, and dry-burning protection. Automatic power-off in case of abnormalities. No open flame heating, explosion-proof and durable, ensuring safer driving.

4. Strong Low-Temperature Start-up and High Environmental Adaptability

It can start and operate normally in extremely cold environments down to -40℃, and provides stable heating even in high-altitude and frigid regions, unaffected by severe weather.

5. Energy Saving and Extended Range

The constant temperature control design automatically adjusts power upon reaching the set temperature, effectively reducing overall vehicle energy consumption and extending the vehicle's driving range.

6. Compact and Easy to Install, Simple Maintenance

The compact size and lightweight design, along with the simple wiring layout, make installation convenient and reduce the need for future maintenance, while saving installation space.

1. Heating for New Energy Buses/Buses

Suitable for pure electric and hybrid buses, providing rapid cabin heating to ensure passenger comfort in winter and ensuring stable operation of high-voltage platforms.

2. Power Battery Preheating and Temperature Control

Preheats the battery systems of new energy commercial vehicles and passenger cars, improving battery activity in low-temperature environments, optimizing charging efficiency, extending battery life, and ensuring driving safety.

3. Heating for New Energy Commercial Vehicles/Logistics Vehicles

Suitable for electric light trucks, heavy trucks, and logistics vehicles, meeting the heating needs of the cab, adapting to high-frequency start-stop and complex road conditions, and ensuring stable and reliable operation.

4. Special Vehicle and Energy Storage Support

Used in high-pressure heating scenarios such as electric engineering vehicles, sanitation vehicles, and military special vehicles; can also be equipped with energy storage systems and power station equipment to provide temperature control protection in low-temperature environments.
