CMT1C2
The TCHAIN CMT1C2 11-12.5M engine driven bus air conditioner is a high-performance cooling solution exclusively developed for large commercial buses such as 11-12.5 meter long-haul passenger coaches, intercity transit buses and double-decker buses. Highlighted by a 127000 BTU high cooling capacity and 5-fan 8-blower large coach AC system, this model can quickly cool the large internal space of 11-12.5M buses and maintain a stable temperature even in high-temperature environments, fully meeting the long-time cooling needs of long-haul passenger transport. Equipped with 24V fin & tube coil bus air conditioning technology, it is highly compatible with the electrical systems of mainstream large buses, with efficient heat exchange and stable operation. Produced by a manufacturer with over 36 years of bus air conditioner R&D experience, the CMT1C2 has passed strict durability and continuous operation tests, and is a core supporting product for large bus manufacturers, long-haul passenger transport groups and intercity bus companies in the market. It integrates heavy-duty design and high-efficiency cooling, becoming the first choice for climate control of large long-haul commercial buses.
With a cooling capacity of 127000 BTU, the 11-12.5M engine driven bus air conditioner can quickly cover the large internal space of 11-12.5M long-haul buses, realizing fast cooling in 5-8 minutes, and maintaining a constant temperature of 22-26℃ in the car, even in high-temperature outdoor environments above 40℃.
Equipped with 5 high-power condenser fans and 8 large-airflow evaporator blowers, the product achieves three-dimensional and uniform airflow distribution in the large bus space, eliminating cooling dead zones in the front, middle and rear of the bus, and ensuring the same comfort for all passengers.
Adopting a 24V low-voltage design, it is perfectly compatible with the 24V electrical system of large commercial buses, with stable power supply and no damage to the bus's original circuit. The fin & tube coil structure of the condenser and evaporator greatly improves the heat exchange efficiency, accelerates cooling and reduces energy consumption.
Aiming at the characteristics of long-haul buses such as long-time operation, road vibration and complex working environments, the CMT1C2 adopts a reinforced frame structure and shock-absorbing design for core components, with strong anti-vibration and anti-interference ability, and can maintain stable performance during long-distance continuous operation.

High-Efficiency Heat Exchange of Fin & Tube Coils: The fin & tube coil structure adopted by the condenser and evaporator has a large heat exchange area and fast heat dissipation speed, which is 30% higher than the traditional coil design in heat exchange efficiency, and is suitable for the long-time high-load operation of long-haul buses.
24V System Compatibility & Safety: The exclusive 24V voltage design is fully adapted to the electrical system of large 11-12.5M buses, with over-voltage, over-current and short-circuit protection functions, ensuring the safety of the bus's electrical system and the air conditioner itself.
Strict Durability & Vibration Testing: The product has passed the manufacturer’s professional vibration test, high-temperature continuous operation test and rainproof and dustproof test, which can adapt to the complex road conditions and working environments of long-haul passenger transport, and has a service life of more than 8 years.
Low Fuel Consumption & High Efficiency: Optimized by the professional thermal management team, the air conditioner realizes the balance of high cooling capacity and low fuel consumption, with the average fuel consumption increased by less than 5% during operation, effectively reducing the long-term operation cost of B-end passenger transport companies.

The CMT1C2 11-12.5M engine driven bus air conditioner is manufactured by Guangdong Shunde Taichang Bus Air Conditioner Co., Ltd., a well-known bus air conditioner enterprise with 36+ years of R&D and production experience, nearly 60 finalized products for 6-14 meter buses and a factory area of 20,000 square meters. The company has obtained ISO9001-2015 and GB/T19001-2016 international quality management system certifications, and holds a utility model patent for large bus air conditioner design. With more than 520 professional employees including R&D, production and after-sales teams, it has stable supporting cooperation with dozens of domestic bus manufacturers, and its products are exported to more than 50 countries and regions on five continents, with over 20 years of overseas market operation experience. The company has a mature bulk production capacity, with a monthly output of more than 1,000 sets of large bus air conditioners, and can meet the large-scale supporting needs of bus manufacturers.
