Product Introduction:

forede® Twin Foam Bladder Tanks is a combined pressure-type foam proportioning assembly with two vertical foam bladder tanks connected in parallel, sharing manifold piping, valves and proportioning assembly. Different from single bladder tank, it supports **one tank online for fire suppression while the other tank can be isolated, refilled, inspected or maintained without shutting down the whole foam system**. It adopts bladder squeezing principle: pressurized fire water enters the cavity between steel tank shell and internal rubber bladder, squeezes the bladder to deliver foam concentrate into proportioner and mix with water at fixed ratio.suitable for multiple hazard systems, sprinkler systems and any other system operating under variable, non predictable, flow and pressure conditions.

Products Description

Overview

forede® Twin Foam Bladder Tank System is a fire protection foam proportioning system consisting of two foam bladder tanks connected to a common piping network. It is designed to supply foam concentrate and mix it with water at a predetermined proportion to produce foam solution for firefighting.

Unlike a conventional single foam bladder tank system, a twin-tank arrangement provides greater foam concentrate storage capacity and can offer operational flexibility for large-scale fire protection installations.

Twin foam bladder tank systems are commonly considered for industrial facilities where reliable foam firefighting capability and a substantial foam concentrate supply are required.

FAQ

Q: What mixing ratios does this twin bladder unit support?

Standard setting for **3% and 6% foam concentrate (AFFF, AR-AFFF, fluorine-free foam)**, proportioning accuracy meets NFPA 11 and EN13565 requirements. We configure the proportioner according to customer's foam type and mixing ratio requirement before delivery.

Q: What is the working pressure range and test pressure?

Standard working pressure: **0.6–1.2 MPa.
Hydraulic strength test pressure: 1.5 MPa; sealing test pressure: 1.32 MPa. Custom pressure rating available on request for special marine or high-pressure projects.

Q: What materials are used for tank shell and internal bladder?

Tank shell: Carbon steel Q235B with anti-corrosion epoxy coating; stainless steel 304/316 is optional for coastal, offshore and corrosive environments.
Bladder: EPDM rubber as standard, compatible with most common foam concentrates. Special NBR or custom elastomer bladder can be selected for specific foam chemicals.
