Key Features


Tailored Cooling for Medium-Sized School Buses

The 8.3-9.3 meter school bus engine driven air conditioner has a precisely calibrated cooling capacity, which quickly cools the closed school bus cabin and maintains a constant temperature, creating a comfortable riding environment for students and complying with school bus safety and comfort standards.


Hybrid Coil Design (Fin & Tube + Parallel Flow)

The evaporator adopts a fin & tube structure for uniform cooling, and the condenser uses a parallel flow design for fast heat dissipation, achieving a perfect balance between cooling effect and energy efficiency for medium-sized bus cabins.


Reliable 4+6 Air Circulation System

4 high-efficiency condenser fans and 6 evaporator blowers realize large air volume and low-noise operation, avoiding excessive noise interference in the school bus cabin and ensuring quiet and comfortable riding.


24V Low-Voltage Stable Power Supply

The 24V industrial-grade low-voltage design is fully compatible with the electrical system of 8.3-9.3 meter medium-sized buses, with stable power output and no damage to the bus’s original circuit system during frequent start-stop.


Vibration-Resistant for Short-Distance Trips

The whole machine is designed with shock-absorbing components, with strong anti-vibration and anti-impact performance, adapting to the frequent start-stop and complex road conditions of short-distance medium-sized buses.

Technical & Quality Advantages


Faster Heat Dissipation via Parallel Flow Condenser

The parallel flow condenser has a more compact structure and larger heat exchange area than the traditional coil, which can quickly dissipate heat generated by the compressor, improving the overall cooling efficiency of the unit and adapting to the high-frequency working mode of short-distance buses.


Uniform Cooling with Fin & Tube Evaporator

The fin & tube evaporator realizes uniform air supply in the medium-sized bus cabin, eliminating local overcooling or overheating, and is especially suitable for the closed cabin of school buses to ensure consistent cooling in every seat area.


Energy-Saving for Frequent Start-Stop Scenarios

The optimized engine-driven energy conversion system reduces power loss during frequent start-stop, and the low-power operation mode effectively lowers the fuel consumption of the bus and the daily operating cost of the fleet.


School Bus Safety-Oriented Design

The unit uses fireproof and environmental protection materials, with a compact installation structure that does not occupy the passenger space of the school bus, and the operation is fully automatic, without the need for manual adjustment, which is in line with the safety operation requirements of school buses.
