Cement cooling for rail and switch sleepers
Messer supplies liquid nitrogen to RAIL.ONE, a leading manufacturer of rail and switch sleepers made of concrete. The gas is used to cool the cement at the Schwandorf site. The ultramodern plant produces up to 180,000 running meters per year of prestressed concrete switch sleepers. The temperature of the cement directly affects the quality of the concrete and ultimately product quality and safety. RAIL.ONE has been producing concrete sleepers for Deutsche Bahn since 1954. As part of the international PCM RAIL.ONE Group, the company markets concrete sleepers and rail track systems for metropolitan and intercity rail links and also provides engineering services and turnkey plant construction solutions.
