The TCD12D is a flagship new energy air conditioner developed by TCHAIN, designed for 10.0-12.0m electric coaches and urban transit vehicles. With a rated cooling capacity of 32,000 Kcal/h and heating capacity of 30,000 Kcal/h, this rooftop unit delivers stable temperature control for large passenger compartments. It has been successfully deployed in multiple regions and vehicle types. Below are the typical application cases.
Region: Sabah, Malaysia
Applicable vehicle: Urban city commuter trains
Sabah, Malaysia has a typical tropical rainforest climate, with year-round high temperature and high humidity. Urban city trains serve as the backbone of local public transit, featuring high operation frequency and dense passenger flow, which sets strict requirements on the cooling capacity, weather resistance and operational reliability of on-board air conditioners.
The TCD12D unit adopts rooftop hoisting installation, which fits perfectly with the train roof structure. Its 32,000 Kcal/h strong cooling capacity can quickly bring down the cabin temperature even under full passenger load and high ambient temperature. The wide DC 420-720V voltage range adapts to the power supply system of local trains, and the high-protection components resist humid and rainy weather. With stable performance during high-frequency daily operations, the TCD12D provides a cool and comfortable riding experience for local commuters.
Region: Domestic intercity passenger transport lines in China
Applicable vehicle: 10-12m luxury express passenger coaches
These coaches operate on medium-to-long distance intercity routes, with high requirements for continuous cooling stability and passenger comfort. The TCD12D electric air conditioner matches the vehicle size perfectly, with an air flow of 5,400 m³/h to ensure uniform temperature throughout the full cabin. Its low-noise design also improves the travel experience for long-distance passengers.
Supported by R410A refrigerant and high-efficiency heat exchange system, the unit maintains stable cooling performance even in hot summer conditions, making it an ideal choice for high-end intercity coach fleets.
Region: Intercity passenger transport market in Bangladesh
Applicable vehicle: 10-12m long-distance passenger coaches
Bangladesh has a tropical monsoon climate with long periods of high temperature and high humidity, which puts forward strict requirements on the cooling capacity and weather resistance of bus air conditioners.
The TCD12D electric bus AC unit adapts to DC 420-720V wide voltage range, and its high-protection components adapt to the local complex operating environment. With 32,000 Kcal/h strong cooling capacity, it can quickly cool down the fully-loaded cabin under high ambient temperature, providing a cool and comfortable ride for local passengers. This model has become a popular choice for local intercity bus operators.
Region: Airport dedicated lines in China
Applicable vehicle: 10-12m airport shuttle commuter buses
Airport shuttle buses feature high-frequency round-trip operations, large passenger flow and frequent door opening and closing, requiring the air conditioning system to cool down quickly and operate stably under frequent load changes.
The TCD12D new energy air conditioner supports fast cooling with its high-efficiency compressor and large air volume design. Its lightweight rooftop structure (≤310kg) also helps reduce the vehicle load. With reliable operation under frequent start-stop cycles, it fully meets the intensive operation needs of airport shuttle lines.
The TCD12D electric air conditioner shows excellent adaptability to different regions and vehicle types:
Covers 10.0-12.0m new energy coaches and urban transit vehicles of various brands
Adapts to high-temperature, high-humidity and other complex tropical climate environments
Meets the needs of long-distance intercity, urban rail transit, airport shuttle and other operation scenarios
With IATF16949 certified quality and stable performance, the TCD12D provides reliable air conditioning solutions for transport operators around the world.
