TD40
The TCHAIN TD40 10-11m Electric Bus Air Conditioner is a high-performance cooling solution exclusively engineered for 10-11 meter new energy electric buses, ideal for buyers including public transport operators, electric bus manufacturers and cross-border coach fleet managers. With a super cooling capacity of 28000KcaL/h and a wide DC voltage range of 420V-720V, this unit perfectly matches the high-voltage power supply system of electric buses such as FOTON, ensuring stable and efficient cooling even during long-hour continuous operation. Integrated with premium refrigeration components including a high-efficiency compressor, evaporator expansion valve and condenser blower, the TD40 features a compact structural design that saves installation space and reduces refrigerant leakage risks. As a flagship product of TCHAIN, it has passed rigorous performance testing and is certified for industrial use, making it a reliable choice for large-scale electric bus fleet procurement.
Equipped with a high-power refrigeration core, the 28000KcaL/h cooling capacity easily meets the cooling needs of 10-11 meter electric buses with large passenger capacity, maintaining a comfortable in-car temperature of 18-26℃ even in high-temperature environments.
Supports DC420V-720V wide voltage input, perfectly adapting to the high-voltage power system of mainstream new energy electric buses, with over-voltage and under-voltage protection to avoid component damage caused by power fluctuations.
Adopts a one-piece design of compressor, receiver series, evaporator and condenser, with optimized suction and discharge lines to improve refrigeration cycle efficiency and reduce energy consumption of electric buses.
All components are industrial-grade and anti-vibration designed, able to withstand the complex road conditions of urban public transport and long-distance coach operation, with a low failure rate and long service life.
