The invention is a fire suppression system. A first dispensing assembly 22 is adapted to provide a flow of liquid fire suppression chemical at a constant pressure to a first outlet port 24. A first valve assembly 26 is coupled to the first outlet port 24 and is adapted to control the flow of the liquid chemical as a function of the temperature thereof to a second outlet port 34. A second valve assembly 32 is coupled to the second outlet port 34 of the first valve assembly 26 and is adapted to meter the liquid chemical as a function of the inlet pressure level and selected flowrates and to cause the liquid chemical to partially vaporize, forming a liquid/vapor phase, first mixture. A second dispensing means 44 is provided which is adapted to deliver a second mixture composed of water and foaming agent at a constant pressure. A nozzle assembly is coupled to (1) the second dispensing assembly 44, via line 46, (2) to a third outlet port 38 of the second valve assembly 32 and, additionally, (3) to a source of ambient air. The nozzle assembly 42 is adapted to fully vaporize the first mixture and to expand the vaporized chemical to ambient pressure. Thereafter, the nozzle assembly 42 combines the ambient air and the vaporized chemical at ambient pressure forming a third mixture and to further combine the third mixture with the second mixture by encapsulation, forming a foam wherein the bubbles of the foam contain the third mixture.
