Description
These water powered High Expansion Foam Generators are manufactured in corrosion resistant materials. No outside source of power is required for operation, only the foam solution under pressure.
Available with smoke extraction. Suitable for use where rapid coverage and total flooding with foam are required for control and extinguishment of fires in confined areas.
About High Expansion Foam Generators
Although limited to special applications, high expansion foams make an excellent firefighting tool. This method of fire suppression involves filling a void with foam bubbles. This creates oxygen deprivation at the point where fire and air interfaces. The water content of the foam bubbles also generates a cooling effect. These foams have been found to be effective in the control of liquefied natural gas fires, where large releases of liquefied gas are contained in the dike areas. Other applications include warehouses containing tyres, hazardous materials or pesticides in which contaminated effluents can be minimised due to the reduced water usage.
Unlike most other foam systems that are designed around a given surface area, high expansion foam systems are calculated based on given volumes. So they are best suited for areas that are contained on the top, bottom and sides. In designing these systems, it is necessary to factor the effect of openings as well as the effect of a sprinkler discharge (if applicable) on the finished foam. High expansion foams use very little water in comparison to the volume of foam generated. This minimises the run-off of foam/water solution mixed with the spilled flammable liquid. This, in turn, reduces the costs associated with cleanup.
