Description
The Model N-Pipe Type 2V system for biomass storages integrates VID Fire-Kill low pressure watermist nozzles type BM-1 with thin walled stainless steel pipes. One N-Pipe Type 2V is 6 meters and it includes 12 nozzles. The system is designed for use in different applications, for example in large indoor biomass storage and power plants.The design saves cost on fittings as well as reduces the risk of getting impurities into the systems when nozzles are installed since there are less connections. The design also ensures correct nozzle spacing installation. The system is to be installed in rows covering the entire enclosure either in designated zones or connected into one large zone.
Approval
The Model N-Pipe Type 2V system for biomass storages has successfully been fire- and component tested to DFL test method 90329-3 with amendments 150225-2, designed in accordance with CEN/TS 1492 annex B.
Application areas
The Model N-Pipe Type 2V system for biomass storages is designed to protect dry or wet feedstock material typically in sized less than 150 mm in any dimensions and stored in piles up to a height of 8 m.
N-Pipe Type 2V summary:
- Robust design, reducing the need of fittings
- Small nozzle pitch allows the water to distribute very fine and even
- Large nozzle orifices reducing possibility of clogging
- Low water pressure
- Low water flow
