The TENOR Spiral Silencer System is the ideal solution wherever you need a high level of silencer performance coupled with a small installation space. The spiral-shaped exhaust chamber on the inside of the silencer housing provides the grea­test possible curved surface, which serves to effectively break up linear sound waves. The system can be used practically anywhere. The TENOR Spiral Silencer is optimally suited for use in ve­hic­le construction and mechanical en­gi­neer­ing systems as well as in plant en­gi­neer­ing systems or the shipbuilding in­dus­try to sustainably re­duce noise emis­sions from diesel, petrol and natural gas en­gi­nes.

  • Flexible mountings 360° positioned as required
  • Individual connectings, welding ends, plug socket, V band con­nec­ting or flange
  • Individual adaptation an construction spa­ces, special custamized designs pos­sible
