NF GROUP Electric Car Window Defroster 6kW High Voltage Electric Defroster
Electric Bus Defroster Description
The Water-Electric Integrated Defroster from NF GROUP is a dual‑purpose defrosting unit designed for commercial and new energy vehicles.
It integrates a high‑voltage relay and offers two independent heat sources: PTC (Positive Temperature Coefficient) electric heating and waste heat from the engine or battery coolant circuit.
These two heating modes can be used separately or simultaneously, providing exceptional flexibility and thermal efficiency.
Electric defroster for electric buses Key Advantages
- High-performance brushless fan – Rated for over 20,000 hours of continuous operation, ensuring long‑term reliability.
- Extended PTC dry heating life – The PTC element can operate in dry conditions for more than 500 hours without performance degradation.
- EU compliance – The high voltage electric bus defroster meets strict European standards and has obtained the E‑Mark certificate, certifying its legality and safety for the European market.
Electric Bus Electric Defroster Performance Features
- Integrated water‑electric design – Accommodates both high‑voltage electric heating and coolant heating simultaneously or independently, offering maximum flexibility and high thermal efficiency.
- Separate layout – The PTC heating core and the water tank are arranged separately, significantly improving safety.
- IP67 protection – The PTC heating element is rated IP67, providing excellent resistance to dust and temporary immersion, which enhances safety in harsh environments.
- Compact structure – Easy to install and space‑saving, ideal for vehicles with limited mounting space.
NF GROUP offers full customization for this water‑electric integrated defroster.
