Import Ac09 Bus Air Conditioning Units — Buy in Bulk from Supplier in China

The Ac09 Bus Air Conditioning Units from Zhengzhou Corun Tech Co., Ltd. are roof-mounted integrated cooling systems engineered for passenger buses and large commercial vehicles. The units employ a direct-expansion refrigeration cycle with R134a or equivalent low-GWP refrigerant, driven by an engine-belt compressor or an independent electric compressor depending on the variant specified. The manufacturer specifies a cooling capacity calibrated for bus interior volumes typical of 10-12 metre coaches, with airflow distribution through ducted ceiling plenums. Zhengzhou Corun Tech is located in Henan Province, China, with the manufacturing and administrative address at 2# Tianming Road, Zhengzhou 450056.

The Ac09 series utilises aluminium micro-channel heat exchangers for the condenser and copper tube-and-fin construction for the evaporator, a combination that reduces refrigerant charge volume while maintaining heat transfer efficiency. The housing is formed from galvanised steel with powder-coated finish to resist road salt and stone chip damage during operational life. Control is managed through a digital thermostat with CAN bus interface capability for integration with modern vehicle multiplexed electrical architectures. Standard electrical requirements are 24 VDC for control circuits, with the compressor clutch or electric compressor drawing from the vehicle main electrical system or a dedicated alternator.

Fleet operators, bus manufacturers, and aftermarket refurbishment contractors represent the principal market for the Ac09. The units are suited to intercity coaches, tour buses, and employee shuttle vehicles where passenger comfort is a commercial priority.
