About AFFF Foam Systems
Aqueous Film-Forming Foams (AFFF) are based on combinations of fluoro-chemical surfactants, hydrocarbon surfactants, and solvents. This agent requires a very low energy input to produce a high quality fire fighting foam. Consequently, they can be applied through a wide variety of foam delivery systems. This versatility makes AFFF systems an obvious choice for airports, refineries, manufacturing plants, municipal fire departments, and any other operation involving the transportation, processing, or handling of flammable liquids.
Alcohol Resistant Fire Fighting AFFF Foam Systems
Alcohol-resistant foams are based on AFFF chemistry to which a polymer has been added. ARCs are the most versatile of the fire fighting foam agents in that they are effective on fires involving polar solvents like methanol as well as hydrocarbon fires such as gasoline.
Mixing Foam Systems with Water
A foam system requires proportioning equipment to mix the foam with water in the required concentration. Automatic pressure balancing valves regulate the foam concentrate pressure to match the water pressure.
AFFF Foam System Bladder Tanks
Foam concentrate is often stored in a bladder tank system. In AFFF systems a bladder tank containing a nylon reinforced elastomric bladder is used to store the foam concentrate. System water pressure is used to squeeze the bladder providing fire fighting foam concentrate, at the same pressure, to the proportioner. With bladder tank foam systems, no external power is required, and little maintenance is needed.
