A turbex foam generator can be used in rapid demolition and decommissioning activities to fill a portion (preferably the whole) of the structure due for demolition/decommissioning with ‘wet foam’ to replace the ‘free air’ normally present within the structure. This reduces the amount of dust produced during collapse and lessens the shockwave that is generated when explosive charges are fired.
This type of system can be particularly useful for the decommissioning of buildings where dangerous substances may have been stored and where the building has been sealed to prevent the escape of the ‘wet foam’. This could be in a number of different situations including, but not limited to, buried gas tanks, nuclear plants, and incineration facilities.
The Angus Fire Hi-Combat Turbex Industrial Systems are designed to produce high expansion foam from an Angus Expandol high expansion fire fighting Foam concentrate at a nominal ratio of 500:1(500 parts of air to one part of foam solution). Each unit utilises forced air technology by a specially developed efficient water driven fan, overcoming any back pressures that would stall a simpler blower type unit.
These units can be supplied as standard with a self-inducing model or a fixed inductor that requires the application of a premix solution of Expandol foam concentrate and water from a dedicated expansion tank. Colour-coding across the range ensures fast and easy assembly for optimum performance.
The Angus Hi-Combat Turbex can be fed with a wide variety of high expansion foam concentrates to suit most Class A and Class B fire risks. Angus’ patented Expandol high expansion fire fighting foam concentrate is specially formulated with superior drainage characteristics to increase the ability of the resulting foam to carry water to the flame. This increases the cooling effect of the high expansion foam and also helps to suppress flames by enveloping them, and by cutting off oxygen.
