The FIREKILL™ system for protection of ordinary hazard OH1 is unique as it requires very low water pressures and water flow rates. The system utilized the automatic low-pressure water mist nozzles Model OH-SW4 which are patented automatic sidewall, fine water spray nozzles.
The OH-SW4 nozzle create a homogenous fine water mist, 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. OH-SW4 can be used for securing Offices, Public areas of low fire load, hotel rooms, rooms in hospitals, care homes, schools, flats, accommodation areas as well as any other comparable risk using CLT/BLC construction.
