Bladder Tank
Foam Extinguishing Systems

Foam Bladder Tanks

Foam bladder tanks offer a reliable and simpler method of foam proportioning. The bladder tank system is a pressure rated tank with an internal rubber bladder. When the system is started, the incoming water applies pressure to the rubber bladder, which supplies pressurised foam concentrate to the proportioning device (ratio controller). The ratio controller meters the foam concentrate into the fire water line to create the foam solution. The solution is then piped to the discharge devices protecting the hazard area. Bladder tanks are available in horizontal and vertical arrangements, fully pre-piped. The tanks carry UL, FM and CE approvals.
