RailMac BT-2.4/10AD

The BT-2.4/10AD is a high-performance on-board air compressor specifically engineered for Harmonized electric locomotives. As a critical air supply device for core components such as the train’s braking system and pneumatic control systems, it delivers reliable high-pressure clean air to meet the multi-system air demand of the locomotive.​
Featuring a 24kW motor direct-drive design, the product boasts a nominal volume flow rate of 2.4 m³/min and a rated exhaust pressure of 1000 kPa, ensuring stable and efficient air output. Developed and manufactured in strict compliance with rigorous rail transit industry standards, it offers full operating condition adaptability. Adopting an air-cooled cooling method and supporting S1 continuous duty cycle, it can operate stably in extreme environments ranging from -40℃ to 55℃. The direct-drive connection structure simplifies the transmission chain, enhancing operational efficiency and reliability, making it a core supporting equipment for safeguarding the safe and efficient operation of electric locomotives.

Advantages of BT-2.4/10AD

  • BT-2.4/10AD offers four core advantages tailored for Harmonized electric locomotives. Firstly, it delivers efficient air supply with a 2.4 m³/min nominal volume flow rate and 1000 kPa rated exhaust pressure, rapidly providing stable high-pressure air for braking systems and pneumatic valves. Its 24kW power and direct-drive connection achieve over 95% transmission efficiency, ensuring lower energy consumption and faster response than traditional designs.

  • Secondly, it excels in full operating condition adaptability, operating continuously at -40℃ to 55℃ for plateau, cold, and high-temperature environments. The air-cooled system, with no extra coolant, endures locomotive vibrations and enables easy maintenance.

  • Thirdly, supporting S1 continuous duty cycle, it realizes 24/7 non-stop operation to meet long-distance locomotive needs without shutdowns. The motor-driven design ensures low noise, minimal vibration, and extended service life by reducing interference with precision equipment.

  • Lastly, custom-developed for Harmonized electric locomotives, it features perfectly matched dimensions and interfaces for hassle-free installation. Compliant with rail transit standards, it passes rigorous tests to guarantee stability and safety as a core component.
