AFFF Systems

Any type of system – Wet, Dry, Preaction or Deluge – can be adapted to include the injection of AFFF foam concentrate in order to combat high risks such as flammable fuels and alcohol. The primary components added to the sprinkler system riser include bladder tanks to hold the foam concentrate, concentrate control valves to isolate the sprinkler system from the concentrate until activation, and proportion ers (controllers) for mixing the appropriate amount of foam concentrate with the system supply water. Other types of foam/water systems require similar foam equipment.
