These Bladder Tanks are one component in a balance pressure foam proportioning system. It requires no external power other than water pressure to ensure correct operation. Both vertical and horizontal bladder tanks are designed and constructed in accordance with the latest revisions to ASME code. Proportioning is the introduction of foam concentrate into a flowing water stream to produce a foam solution. Chemguard offers a variety of proportioning equipment that will accurately accomplish this task with various types of systems such as Bladder tanks, balance pressure proportioning systems and inline balance proportioning systems (ILBP's).

Chemguard's line of UL listed and FM approved vertical and horizontal bladder tank systems are available from 25 gallons to 2,500 gallons in the vertical and 100 gallons to 6,000 gallons in the horizontal style. These systems provide a dependable and cost-effective foam fire protection for a variety of flammable/combustible hazard areas and because water is the primary operating medium, they are easy to operate and maintain. Bladder tanks are frequently used in small aircraft hangers, warehouses, helicopter decks, and storage facilities. When the tank is in operation, water is applied to the outside surface of the bladder and subsequently displaces the foam concentrate, which is contained inside the bladder, which then makes its way to the proportioning device and then is injected into the water stream.
