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 FIREKILL™ 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 Watermist Nozzles Model OH-DC1 are patented automatic, fine water spray nozzles. The OH-DC1 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.

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.
