DescriptionThe Bladder Tank Proportioning System is a balancedpressure proportioning system, requiring no external powerother than an adequate water supply. A bladder tank, withan appropriate proportioner(s), injects foam concentrateinto the water supply of a re protection system andautomatically proportions over a wide range of ows andpressures.

The Bladder Tank Proportioning System employs waterto pressurize the bladder and force foam concentrate tothe ratio controller. The water supply simultaneously feedsthe ratio controller and the bladder tank. As water owsthrough the ratio controller the level of pressure reductionincreases, thereby affecting a corresponding pressuredrop across the foam concentrate metering ori ce. Thecorresponding pressure drop results in foam concentrateow that is proportionate to the water ow through the ratiocontroller. As both the water and foam concentrate ow intoa common reduced pressure area, it is necessary only tomaintain identical water and foam concentrate pressuresat the respective inlets of the ratio controller.

During operation, the water outside the bladder graduallydisplaces the foam concentrate inside causing the bladderto collapse until the supply is exhausted. The bladder tankmay then be isolated and the system allowed to dischargewater only. Since the bladder tank is pressurized, thebladder should not be re lled during operation.

FeaturesCompatible with all foam concentrates•

Easier to refill than vertical bladder tanks•Bottom foam concentrate discharge keeps feed piping•full, eliminating air pockets and preventing corrosionBetter stability than vertical tanks in earthquake-prone•areasPermanently welded lifting lugs•

ApplicationsFrequently used in aircraft hangars, loading racks, sprinklersystems, and offshore platforms.

Technical SpecifcationsThe National Foam bladder tank system shall be acomplete self-contained proportioning system consistingof a bladder tank, ratio controller, and assembled piping.The bladder tank shall be an ASME code welded carbon

steel pressure vessel with a working pressure of 175psi (12 bar). The tank shall be supplied in the horizontalcon guration and shall be mounted on two permanentlyattached saddle supports with holes for mounting bolts. Aexible, thermoplastic vulcanized rubber internal bladderseparates the foam concentrate from the incoming water.The tank shall have perforated PVC schedule 80 centerdischarge piping, located within the bladder, to ensure thatfoam concentrate ows to the bottom discharge. A sectionof 1-inch I.D. rubber hose installed between the bladderand tank shell, shall extend from the water vent to thewater drain connection, preventing bladder obstruction atthese openings.

The ratio controller (RCF) shall be a anged style formounting in Schedule 40 pipe between two 150# at orraised anges of the same nominal size as the RCF. TheRCF shall be cast bronze with stainless steel hardware andshall be rated for a working pressure of 250 psi (17 bar).The ratio controller shall incorporate a recovery section tominimize the pressure loss through the proportioner andreduce the straight pipe length required after the controller.

A ¼" (6.35 mm) female NPT port for sensing waterpressure at the inlet to the ratio controller water ori ceshall be incorporated into the casting. Each ratio controllershall automatically proportion over the range indicatedon ow range chart without any manual adjustment. Thefoam concentrate inlet shall contain a foam concentratemetering ori ce with eld adjustment feature to allow userto ne tune proportioning.

The ratio controller shall be pre-piped to the bladder tank. All external piping shall be Schedule 40, and shall be brassfor foam concentrate and carbon steel for water. Brass orbronze ball valves of the locking handle type, in accordancewith NFPA requirements for valve supervision, shall besupplied, and shall be complete with identi cation labelson the handles. A ball check valve shall be installed in thefoam concentrate line. Tank shall include all necessarydrain and vent valves, concentrate ll piping, ll cup, andtank content/identi cation labels. External surfaces of tankand piping shall be coated with red high solids acrylicpolyurethane nish.

Approvals and ListingsUnderwriters Laboratories, Inc. (UL Listed)•Factory Mutual (FM)•United States Coast Guard (USCG) to 500 gal.•
