The FIREKILL™ OH nozzles are installed recessed into the ceiling with the nozzle rosette flush with the surface and the nozzle Cover Plate protruding 10-15 mm from the surface, being the only visible parts of the nozzle in its daily use or directly into a visible pipe system in retrofit cases. The FIREKILL™ OH nozzles can be delivered in different paint and finishes making the system blend in with almost any type of surface, securing the aesthetics of the surroundings.
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.
Test and Approvals
FM Approved
The FIREKILL™ OH-DC1 nozzle has been successfully tested to the FM5560 Appendix M, standard for FM Data Processing Equipment Rooms/Halls Above Raised Floors.
