The Process

IT IS NOT A WATER MISTING UNIT – IT IS AN ULTRA HIGH PRESSURE WATER MISTING SYSTEM WITH THE ABILITY TO PIERCE THROUGH NEARLY ANY MATERIAL QUICKLY.

Compartment fire fighting has always had an element of risk attached to it, but never more so than today. The amount of plastics and their derivatives within households and commercial premises, coupled with advanced insulation methods, makes the cocktail even more lethal.

Our system has been developed to enable an early and effective attack on a fire. Using our Nimbus system, fire fighters need not enter the danger zone as, by piercing though a wall, door, roof or window and spraying a fine, but powerful mist of water, the fire is cooled and contained within seconds.  The area is then much safer for fire fighters to enter.

ist of water, within seconds the fire can be cooled and contained.  Conventional fire fighting techniques may then be employed.

The system produces a working pressure of 250bar and uses only 15 L/min or at 300 bar, 30 or 60 litres of water per minute.  An abrasive within the water cuts through any material extremely quickly.  After cutting, cropped-RIV3-jet.jpgthe abrasive can be turned off by the operator, enabling a fine water mist to be immediately projected up to eighty metres into the affected area.

Hot gases produced in a fire can reach temperatures of 900°C +  and with the use of the NIMBUS system, that temperature can be reduced to 90°C in approx forty five seconds without opening the building and risking a lethal backdraft or flashover.

The system has been proved to be effective on fires with all types of risk:

  • With grass fires the ground may be penetrated with water to a depth of 2+ metres
  • Where there is difficult access as with ships and warehouses
  • Where there is flashover potential
  • Where there is offensive ventilation
  • Where there are compressed gas cylinder risks
  • With thermal imaging equipment identifying hot spots in, for example, sandwich panels, chimney fires and old buildings
  • In situations where forensic evidence needs to be preserved

This is a fairly new concept which has the potential to revolutionise the approach to fire fighting. It drastically improves the safety of fire fighters and when its capabilities are fully explored it will be recognised for its contribution to safety, its effectiveness in dealing with difficult fire situations and its environmental benefits.
