Aesthetic
Aesthetic fire protection
The FIREKILL™ NEPTUN 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™ NEPTUN 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. The nozzles can also be delivered with logo print.
Design
Application
The FIREKILL™ NEPTUN OH system for protection of shopping and storage is unique as it requires very low water pressures and water flow rates. The system utilizes the automatic low-pressure water mist nozzles Model OH-PX1 which are patented automatic, fine water spray nozzles. The OH-PX1 nozzle creates 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
DnV MED-B and UK MER-B Approval
The FIREKILL™ NEPTUN OH-PX1 has been tested in accordance with IMO Resolution MSC.265(84) for shopping and storage. The FIREKILL™ NEPTUN OH-PX1 can therefore be used for IMO Occupancy classification (13) Store rooms, workshops, pantries and (14) Other space in which flammable liquids are stored.
