Model OH-VSO, Model OH-L2, Model OH-SW, Model OH-SWC & Model OH-UPR

The pendent installed Model OH-VSO, Model OH-L2, the horizontally installed Model OH-SW and Model OH-SWC, and the upright installed Model OH-UPR nozzles have been designed specifically for effective and reliable protection of most EN OH1 risks and NFPA LH risks.

The pendent nozzles have been designed for all applications and the same goes for the horizontally installed nozzles, if the application allows for the horizontally installed nozzles spacing restrictions. The upright installed nozzle has been designed for protection above false ceilings and in such voids.

Being specifically designed for the protection of these hazard groups, VID Fire-Kill have been able to maximize coverage, while considerably lowering water supply requirements, and utilizing specific nozzle-orientations allows for the most effective fire-protection capabilities.
