Newly Launched: Heating and cooling defroster
Operating Principle:
This integrated defrost uses cold water or refrigerant as the medium and a PTC heating element. Automatically controlled, it uses forced air to perform full-view defrosting or defogging, providing a comfortable driving environment for the driver.
Product Features:
Defrosting and defogging modes include natural air, cold air, and hot air. The medium-7 internally threaded tube-fin water-cooled heat exchanger, also known as a dual parallel-flow evaporator, offers high heat transfer efficiency in a compact design. Foot and face blowing functions provide a comfortable driving environment.
A brushless fan provides high airflow, low noise, and a long lifespan.
An independent digital display panel allows for adjustable air temperature and air volume. The heating element is a high-voltage PTC, IP67-rated, with a continuous dry-burning resistance of over 500 hours.
Based on technical characteristics and application scenarios, applicable vehicle types are categorized as follows:
1. Electric Buses and Long-Distance Coaches
Applications: Luxury buses over 12 meters long operating in cold regions (below -30°C) require rapid windshield defrosting and cabin heating.
Intercity Buses and School Buses
Requirements: Frequent starts and stops require rapid defrosting to ensure driving safety.
Technical Highlights: The fresh air system, combined with the mixed air function, prevents repetitive window fogging.
2. Electric Construction Machinery
Electric Excavators and Wheel Loaders
Applications: Harsh environments such as mines and polar regions require simultaneous preheating of the battery pack and cab.
3. High-End New Energy Passenger Vehicles
Luxury Pure Electric Sedans and SUVs
Applications: Range-sensitive users in cold regions require efficient heating and defrosting.
Commercial Electric Trucks
Requirements: Simultaneous cargo compartment insulation and cab defrosting are required.
Solution: Split design, with a heating and cooling defroster for the cab and an independent PTC air heating system for the cargo compartment.
4. Special Vehicles
Hydrogen Fuel Cell Buses:
Use an electric defroster to preheat the fuel cell stack (60–80°C) to prevent the proton exchange membrane from freezing at low temperatures.
Airport Shuttle Buses:
Wide windshields must be defrosted evenly, with infrared radiation film embedded in the glass interlayer, ensuring a temperature difference of ≤±2°C.
