Product Description

The Model N-Pipe Type I-C1.5 and 3C-C2.5 have been designed for a zoned protection of industrial conveyors. With the zoned approach, the design lowers the design and installation time of the system and makes it fast and easy to incorporate into existing locations. Both systems consist of 6 m lengths of N-Pipe.



Product Approval and Scope


N-pipes Type I-C1.5 and 3V-C2.5 have been successfully tested in accordance with DFL TM 180719-1289-4, designed accordingly to prEN 14972 annex A, for installation in systems including detectors in accordance with DFL test protocol 190307-1276-1. Based on the testing, the N-pipes Type I-C1.5 and 3V-C2.5 can protect closed, semi-closed or open conveyors transporting clean wood residues from forestry or other wood processing activities, coal, wood pellets, etc.


For use in protecting conveyors, the Model N-Pipe Type I-C1.5 and 3C-C2.5 have been tested and approved for use in protecting industrial conveyors. The Type I-C-1.5 6 m length of N-Pipe is fitted with 6 low pressure fine water spray nozzles (Model BM1-28) and the Type 3V-C2.5 6 m length of N-Pipe is fitted with 18 nozzles (BM1-20 and BM1-28). Model N-pipes Type I-C1.5 and 3V-C2.5 are installed in one line or parallel rows, covering the entire conveyor width and length, either as a total flooding design where all pipes are connected to the same riser pipe, or as zones where each zone of N-pipe are connected to a zone deluge valve.

Product Uniqueness

  • Robust design, reducing the need of fittings,
  • Very fine and even distribution of the water mist due to the possibility of small nozzle spacings without increasing the cost for fittings and works,
  • Large nozzle orifices reducing possibility of clogging,
  • Low water pressures,
  • Low water flows
