Foam Systems

Generally, foam systems are installed in industrial fields with class B fire risk. Namely, fires caused by flammable liquid objects.

Such as gasoline, oil, tinner, and paint. Then why foam system and not fire hydrant? Because hydrants use pressurized water media.

As we know, water and oil cannot merge. Putting out a fire on a liquid object like oil will actually result in expanding the fire and be fatal. Therefore, the foam system is the most appropriate for fires in the industrial and oil world. Foam can dampen or envelop flammable liquid objects, and cut off fire-forming elements such as air and heat.
