  1. Oil Free Compressors for Railway Applications Product Information

  2. Railway Compressors have Special Requirements • Robust and shock resistant • Dirt resistant • Temperature resistant • Noise less • Vibration less • Maintenance friendly • Low life cycle costs (LCC´s)

  3. To secure the rail safety requirements the products go through intensive examinations • Brake discs and pads • Brake caliper units • Block brake units • Track brakes Vibration Tests Research Center • Brake discs and pads • Brake caliper units • Block brake units • Track brakes • life cycle tests • shock tests • resonance frequency • demand research • new developments • investigations Climatic Chamber Test benches • type tests • performance tests • bearing diagnostic • low temperatures (-50°C) • high temperatures (+65°C) • material tests Noise Tests Field tests • sound investigations • open air tests • measuring of power and pressure levels • endurance tests • data set monitored • continued controlled

  4. Innovate oil-free compressor • Oil free air (environmental friendly, no downstream contamination) • Less problems with duty cycle • Cold start at -50°C possible without preheat • Almost maintenance-free, much lower LCC • Less complex system/ fewer interfaces (no oil filter, no condensate collector) • Very low noise level and vibrations • Reduced space envelope/ weight • Modular design (communal spares, …)

  5. Innovate oil-free compressor • Oil free air (environmental friendly, no downstream contamination) • Less problems with duty cycle • Cold start at -50°C possible without preheat • Almost maintenance-free, much lower LCC • Less complex system/ fewer interfaces (no oil filter, no condensate collector) • Very low noise level and vibrations • Reduced space envelope/ weight • Modular design (communal spares, …)

  6. Less problems with Duty Cycle Oil lubricated Compressor Oil Free Compressor • Recommended DC oil lubricated compressors >30% • At low DC´s condensate falls out in the crankcase (temperature changing's) • This reduced the lifetime of oil lubricated compressors, secondary damages are possible! condensate condensate Crankcase Oil Water

  7. Innovate oil-free compressor • Oil free air (environmental friendly, no downstream contamination) • Less problems with duty cycle • Cold start at -50°C possible without preheat • Almost maintenance-free, much lower LCC • Less complex system/ fewer interfaces (no oil filter, no condensate collector) • Very low noise level and vibrations • Reduced space envelope/ weight • Modular design (communal spares, …)
