Fire Fighting Foam Sprinkler

Foam Sprinkler system typically consists of open type foam discharge devices "Foam-Water" Sprinklers, to have an effective distribution of foam in areas to be protected. The system is usually controlled by automatic deluge valve, which is actuated by one of the detection devices, also installed in the same area as Foam-Water sprinklers. As soon as there is detection of fire, The Foam-Water sprinkler immediately discharge foam for the complete area. These systems can also be used for discharging water for some initial period followed by foam discharge for longer period. For these applications, foam bladder tank proportioners are very commonly used for effective proportioning and supply of foam solution. In-line inductor may not be suitable because it is a fixed flow device and if in case few foam-sprinklers get clogged/blocked due to some reason, then effective foam induction will not take place at the inline inductor due to lower flow.
