NFF XFlow Water Mist Solutions

The Novenco Fire Fighting (NFF) XFlow® water mist system gives you the opportunity to integrate local and full fire protection in a single system. The solution can be applied for total flooding, local application fire fighting (LAFF) and accommodation areas.

The NFF water mist system has a unique XFlow water mist nozzle, which spreads fine water mist that extinguishes the fire fast, without any risk to the crew or equipment.

The NFF water mist system creates a mist of fine water droplets. Droplets in variable sizes circulate in the airfl ow, suppressing the supply of oxygen and absorbing the heat energy and that way it breaks the chain of combustion. Water is an effective agent for fire fighting as it is readily available and environmentally friendly. When water is added as mist it is most efficient at reducing and dissipating heat and thereby controlling, suppressing and extinguishing a fire.

KEY FEATURES 

  • Quick release
    The system can be released immediately without evacuation as it is harmless to crew and machinery. This reduce the risk of damaging surrounding equipment
  • Compact design
    The NFF water mist system uses water from the vessel’s fresh water tank, with a backup connection for seawater. No dedicated storage space is required, increasing the overall productive space available on your vessel.
  • Low water consumption
    The secret of the XFlow technology is the combination of very fine water droplets and water mist using small water consumption. The droplets cool down the fire and extinguish it while the water mist encapsulates and suffocates the fire by keeping out the oxygen.
  • Higher safety level
    Water is an effective agent for fire fighting as it is readily available and environmentally friendly. When water is added as mist it is most efficient at reducing and dissipating heat and thereby controlling, suppressing and extinguishing a fire.
  • Standard components
    The NFF water mist system uses a water mist nozzle with low working pressure and low water flow. The pipe system components such as fittings and valves are standard components, keeping installation and maintenance costs low.

WHAT MAKES XLOW TECHNOLOGY DIFFERENT?

The secret of the NFF XFlow technology is a combination of fine water droplets and water mist, giving optimal system performance.

The water droplets cool the surface preventing reignition, while the mist encapsulates the fire and suffocates it by restricting the oxygen flow. The droplets stabilize the mist extinguishing the fire with minimum damage to machinery and other vital installations. This makes the system more efficient for certain types of fires compared to high pressure water mist systems, even though both systems have to pass the same tests.

The NFF water mist system can be released immediately when a fire is detected. There is no need to evacuate the protected room before release, as water represents no risk to humans or the environment. Because the fire fighting system can start immediately, the risk of the fire spreading is significantly reduced.

 

TECHNICAL INFORMATION

SYSTEM DESCRIPTION AND CONFIGURATION

For engine room systems, the nozzles are mounted in a dry pipe system and released in sections through a total flooding system or as individual objects through local fire fighting systems. The system activation for a section is done manually from release stations in connection with the protected area or remotely from a release panel located at a fire control station, ECR or wheelhouse and can be done automatically or manually.

For accommodation areas, the nozzles are mounted in a wet pipe system and each water mist nozzle work automatically and independently. The nozzles activate when the fire reaches a certain temperature. The water mist is confined to the area or object affected by the fire, and the system can be activated without closing all vents and full evacuation of staff.
When a water mist nozzle is activated, water starts flowing through the pipes, causing the pressure to drop and the pumps to start. This triggers an optical and acoustic alarm on the bridge.

The NFF XFlow water mist system uses water from the vessel’s freshwater tank. The system is also connected to seawater for back up operations. No dedicated storage space is required, increasing the overall productive space available on your vessel.
