Description

Application

The FIRE KILL™ Model OH-DC1 for protection of Data Processing Equipment Rooms/Halls Above Raised Floors is unique as it requires very low water pressures and water flow rates. The Automatic Low-Pressure Water Mist Nozzles Model OH-DC1 are am patented automatic, fine water spray nozzles. The OH-DC1 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.
