Atlas Copco’s Railway Competence Center will soon deliver the first of 26 SFR 5 kW oil-free compressors with integrated maintenance-free dryers, including 150 liter air tanks, to Vossloh-Kiepe in Germany, which is upgrading the BRU’s tram system in Utrecht, Netherlands. The scope of the project includes replacing the compressed air and air treatment equipment on BRU’s 1980’s SIG railcars. Atlas Copco presented a solution which offers dry and 100% Class Zero oil-free air for the brake systems.
BRU’s original SIG railcars featured compact compressed-air systems, but they were oil-lubricated and non-cooled piston compressors with separate service-intensive desiccant dryers. When BRU requested proposals to overhaul these compressed air systems, Atlas Copco suggested the replacement of each old unit with a 100 percent oil-free unit with minimal noise and vibration levels, forced cooling and a fully integrated air treatment system.
The new system is fully compatible to the vehicle structure. The new compressor is designed as an integrated solution. The vehicle interface (mounting points) can be used without any modifications. The new compressor is adapted by an auxiliary frame. This allows a quick and easy installation on the vehicle.
