Bladder Tank with pre-assembled Deluge Valve

Foam Bladder Tanks offer a reliable and simpler method of foam proportioning. Bladder Tank system includes a pressure-rated tank with an internal rubber bladder. Upon system actuation, incoming water applies pressure to the rubber bladder, which supplies pressurized foam concentrate to the proportioning device (ratio controller). The foam ratio controller meters the foam concentrate into the fire water line, creating foam solution. The solution is then piped to the discharge devices protecting the hazard area. Bladder tanks are available in horizontal and vertical mounting with a completely pre-piped option. HD Foam Bladder Tanks carry UL, FM and CE Approvals.
