The FIREKILL™ NEPTUN OH system for protection of corridors is unique as it requires very low water pressures and water flow rates.
The system utilizes the Automatic Low-Pressure Watermist Nozzles Model OH-CO which are patented automatic, fine water spray nozzles.
The OH-CO nozzle creates a homogenous fine watermist, which absorbs heat, reduces radiant heat and causes oxygen depletion near the fire, which in turn controls and suppresses the fire. This homogenous mist consists of a high concentration of very small droplets. Because of the small mass of the droplets, the nozzle creates a large coverage, further minimizing the water expenditures and hydrating nearby combustibles.
