Bladder Tank Foam Proportioning System

Foam Bladder Tanks offer a reliable and simpler method of foam proportioning. The Bladder Tank system includes a pressure-rated tank with an internal elastomeric rubber bladder. Upon system actuation, incoming water applies pressure to the rubber bladder, which supplies pressurized foam concentrate to the foam proportioning device (ratio controller). The foam ratio controller meters the foam concentrate into the fire water line, creating a 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. These are very commonly used in low expansion foam fire fighting systems. HD Foam Bladder Tanks carry UL, FM and CE Approvals. Please contact our sales for further details on approvals and certifications.
