INTERTECH plus has been producing high quality elements made of recycled rubber for damping noise and vibrations generated by railway and tram transport for 15 years. Our special noise reductions system – CNR (Complete Noise Reduction) – uses the state-of-the art knowledge and measurements from real operation which are consequently transferred to production. The CNR compete system for noise and vibration absorption consists of dampening elements which can be incorporated into any structure of the line. CNR can be produced with the team of our technicians according to the project or investor‘s requirements. Thanks to CNR, we improve the environment at the range of 3 – 20 dB.
