Compressed air is widely used on trains. It is used in particular for braking, suspension, pantograph, opening and closing of doors, window sweeping, toilet blocks, etc.

CHAUMECA TECHNOLOGY is involved in the design and production of on-board motor-compressors-dryers. The compression is carried out on the basis of the so-called non-lubricated piston technology. The drying part is designed in compliance with the imperatives of compactness, lightness, durability and maintainability.

CHAUMECA TECHNOLOGY has been supplying SNCF, SNCB and RATP for several decades, for all rolling stock (TGV, metro, tramway, etc.).
