Foam generators are designed and applied using a high expansion foam extract at times when foam suppression systems are to be made and / or where large volumes of enclosed volumes need to be foamed very quickly. The function of the foam generator in the system is to increase the volume of the solution by increasing contact with air. Indoor fires on which burning rate is very high and the fire needs to be controlled very quickly, the flow demand and application time are established according to NFPA-11 guidelines using high expansion foam.
