Description
IFEX3000 has applied advanced aerodynamics technology from flow engineering applications involving liquid/gas mixtures to create IFEX3000 water mist firefighting systems. The IFEX3000 technology creates a narrow distribution of ultra-fine water mist, foam, or CAFS using specialty nozzles.
The droplets create an enlarged surface area (almost 40 times) as compared to a conventional water tender. This results in rapid cooling due to extensive heat absorption and the resultant steam generated expands 1640 times in volume thus inserting the atmosphere around the fire. The combined effect of cooling and blanketing results in effective rapid extinguishing.
Water Mist
NFPA 750 defines water mist as "a water spray with for which the Dv0.99, for the flow-weighted cumulative volumetric distribution of water droplets, is less than 1000 microns at the minimum design operating pressure of the water mist nozzle".
Current water mist systems today deliver anywhere between 50-999µm. Based on the pressure used to create droplets, the classification of water mist is as below.
- Low Pressure: Systems that operate with pressures less than or equal to 12 bar
- Medium Pressure: Systems operating between 12-34.5 bars
- High Pressure: Systems that use pressure greater than 34.5 bar
IFEX3000 Firefighting Nozzles
IFEX3000's firefighting nozzles deliver the optimum droplet size of 150µm and therefore outperform any other comparable product. Water mist prevents re-ignition, requires less water, reliable and versatile.
IFEX3000 systems operate at a low working pressure of 7.5-8.5 bar, without the IFEX3000 patented technology we would have to use approx. 100 bar to achieve the same effects.
The water mist created by the IFEX3000 system helps extinguish fires rapidly due to the dual effect of cooling and blanketing.
Atomization
Water mist removes two of three elements of the fire triangle heat & oxygen.
- Cooling Effect: The optimal droplets created by IFEX3000 water mist systems, increase surface area to maximize the efficient absorption of heat.
- Oxygen Displacement: The droplets evaporate rapidly and expand to displace oxygen in the proximity of the fire.
- Radiant Heat Attenuation: The droplets provide effective protection from radiant heat, Energy is taken away from the fire, due to the IFEX3000 cooling effect.
Water mist prevents re-ignition, requires less water, is reliable and versatile.
Function Principle Animation
The IFEX impulse firefighting procedure uses compressed air to propel a precise amount of water at high velocity, creating an ultra-fine mist that rapidly absorbs heat and displaces oxygen. Watch the animation below to see how the impulse technology works in action.
