Foam Badder Tanks
Vertical foam bladder tanks are space-efficient fire protection units designed for vertical installation, ideal for areas with limited floor space (e.g., utility rooms, equipment corners). They have a steel outer tank and an inner flexible bladder that stores foam concentrate separately from water.
When activated, water enters the outer tank, compressing the bladder to push concentrate into the fire system. Their vertical design saves floor area, ensures stable operation, and fits easily in compact spaces, suiting small-to-medium fire risk zones needing reliable foam storage.

Foam Badder Tanks-vertical type
Vertical foam bladder tanks are fire protection devices that are highly space - efficient and made for vertical installation. They are perfect for places where floor space is at a premium, such as utility rooms and corners where equipment is placed. These tanks consist of an outer tank made of steel and an inner bladder that is flexible. The inner bladder is used to store foam concentrate, keeping it separate from water.
When the tanks are set into action, water flows into the outer tank. This water then squeezes the bladder, which in turn forces the foam concentrate into the fire suppression system. The vertical design of these tanks not only helps to save floor area but also ensures that they operate stably. Moreover, they can be easily installed in tight spaces, making them suitable for small to medium - sized areas that face fire risks and require dependable storage of foam.

FAQ
1. What's the main difference between vertical and horizontal foam bladder tanks?
Vertical tanks save floor space with a tall, narrow design (ideal for compact areas), while horizontal ones fit low-ceiling spots. Vertical models also use natural downward pressure for more stable concentrate discharge.
2. What foam concentrate types are compatible with vertical bladder tanks?
Most water-based foams (AFFF, AR-AFFF, protein foam) work. Ensure the bladder material (EPDM/nitrile) matches the concentrate-avoid strong solvents that may damage the bladder.
3. How much vertical clearance is needed for installation?
It depends on tank capacity: 500L models need ~1.8m, 2000L ~2.5m. Add 30cm extra for top-mounted components (fill ports, valves) to allow maintenance access.
4. Can vertical foam bladder tanks be used outdoors?
Yes, but they need weather protection: install a rain shield for top parts, and use anti-rust coating on the outer steel tank. Avoid direct sunlight to prevent bladder aging.
5. How often should the inner bladder be inspected?
Inspect annually: check for cracks, bulges, or leaks. If the tank is used in harsh environments (high humidity/chemicals), shorten the interval to 6 months.
6. What's the typical service life of a vertical foam bladder tank?
The outer steel tank lasts 10–15 years (with proper anti-corrosion care). The inner bladder needs replacement every 5–8 years, even if no visible damage occurs.
7. Does the tank require power to operate?
No-it's a passive system. Water from the fire suppression network pushes the bladder to release concentrate; no electricity or external power is needed.
8. Can the tank be refilled with foam concentrate on-site?
Yes. Open the top fill port, drain any remaining old concentrate first, then pour new concentrate into the bladder. Ensure no debris enters to avoid clogging.
9. What pressure range is suitable for vertical foam bladder tanks?
They work with system pressures of 0.6–1.6MPa. Exceeding 1.6MPa may damage the bladder, so always match the tank to the fire system's rated pressure.
10. Are vertical tanks suitable for small commercial spaces (e.g., restaurants)?
Yes-smaller capacities (500–1000L) fit in restaurant utility rooms. They're ideal for protecting kitchen grease fires when paired with foam-based suppression systems.
