Defined application


The VID FIREKILL low pressure, fine water spray deluge systems Model N-pipe Type 2V was created for the protection of many different applications. This datasheet covers the use of Model N-pipe Type 2V in large indoor spaces where biomass feedstock (mainly wood) is stored in potentially large piles. The Model N-pipe Type 2V system has been designed with a modular approach in mind, which lowers the time required when designing and installing the system and makes it easier to incorporate into existing locations. To further ease installation, the systems utilize Model N-Pipe Type 2V of ordinarily 6 m in length. Each 6 m length of N-pipe is fitted with 12 low pressure fine water spray nozzles (Model BM-1-28 nozzles) designed specifically for the location size. Two nozzle pairs are installed for every meter in a 90° V-shape formation with 0.5 meters to each pipe end.

Defined application


N-pipes Type 2V has been tested to an extensive list of different protocols. To proof its use as biomass storage area protection system, N-pipes Type 2V has been successfully tested to DFL test method 90329-3 with amendments 150225-2, both designed accordingly to EN 14972 annex A witnessed by Zürich insurance.
