Pneumatic braking: Greater control and efficiency on the railways
The compressed air brake is an essential system on trains, ensuring greater control over braking manoeuvres whilst the train is in motion. The system enables precise control of braking force whilst ensuring uniform braking performance across the entire train.
Dürr Technik offers a range of oil-free compressors that have been specially developed for use in compressed air braking systems. These compressors not only enhance the environmental friendliness and efficiency of the vehicles, but also contribute to the longevity of the braking system and reliable braking performance.
