Product Formation

The vertical fire-fighting foam bladder tank is an integrated fire-fighting foam storage and mixing device, mainly used in fixed fire-extinguishing systems or semi-fixed fire-fighting systems. It isolates water and foam concentrate through a bladder. In the event of a fire, it automatically mixes them in proportion to generate a foam solution, which is suitable for extinguishing combustible liquids (such as oils, chemicals), solid substances (such as wood, paper), and electrical fires, among other scenarios. Its vertical structure is compact, occupying a small area, and is widely used in high-risk fire prevention places such as petrochemical industry, warehousing and logistics, power energy, airport terminals, and shipbuilding.

The 200L to 5000L vertical fire-fighting foam bladder tanks, with their compact structure, high-efficiency mixing capability, and wide adaptability, have become the core equipment for storing and mixing foam concentrate in medium and large-scale fire-fighting systems, providing reliable protection for industrial and civil fire safety.

Product Features

The features of the 200L to 5000L Vertical Fire Fighting Foam Bladder Tank revolve around four core aspects: compact structure, high mixing efficiency, safety and reliability, and flexible adaptability. Combined with vertical design and bladder isolation technology, it forms unique advantages distinct from traditional foam tanks, as detailed below:

Vertical upright design for high space efficiency：Featuring a vertical cylindrical tank, it occupies only 1/3 to 1/2 of the floor space compared to horizontal tanks. Particularly suitable for space-constrained environments such as factories, warehouses, and docks, it requires no additional foundation expansion and offers easy installation.
The capsule isolation technology prevents foam concentrate from deteriorating.：The core component is a flexible, corrosion-resistant capsule (made of butyl rubber/synthetic fiber), which completely isolates the foam concentrate from water physically: Under normal conditions, the capsule stores the foam concentrate while the tank cavity is filled with water or left empty; during firefighting, water flow compresses the capsule to discharge the foam concentrate, which mixes with water, and the capsule resets afterward. This entirely avoids water dilution, contamination, or chemical reactions with the foam concentrate, extending its shelf life.
Modular accessory integration with comprehensive functions: standard inlet, outlet, vent valve, pressure gauge (real-time monitoring of tank pressure), safety valve, level gauge, and maintenance manhole; optional electric heating insulation layer and intelligent level sensor.
High mixing ratio accuracy and stable fire extinguishing effect: Driven by water flow pressure, the bladder contracts, automatically mixing foam concentrate with water at a preset ratio. The mixing ratio error is smaller than that of traditional mixers, ensuring key indicators such as foam solution expansion ratio and drainage time meet relevant standards.
Power-free mixing, energy-saving and efficient: No additional motor or pump is required for mixing. The extrusion and mixing of foam concentrate are accomplished solely by the pressure of fire-fighting water supply, resulting in zero energy consumption and fast response, making it suitable for emergency fire extinguishing scenarios.
Long-life bag design with low maintenance costs: The bag is made of oil-resistant, acid-alkali-resistant, and anti-aging rubber, requiring no frequent replacement under normal use. The tank body is constructed from carbon steel or stainless steel, offering long corrosion-resistant service life, resulting in an extended overall maintenance cycle.
Simple operation with automatic reset: After fire extinguishing, the system depressurizes, and the bag automatically resets under its own elasticity. It can be refilled with foam concentrate (manually or automatically via a replenishment pump to the set liquid level) without manual intervention, reducing operational complexity.
High cost-effectiveness throughout the lifecycle: Initial procurement costs are lower than balanced proportioning mixers, with no additional energy consumption during operation. Maintenance parts (bags, seals) have strong compatibility, making the overall usage cost significantly lower than traditional foam tanks.
Multi-system linkage compatibility: Seamlessly integrates with electric fire pumps, diesel fire pumps, automatic sprinkler systems, foam monitors, foam guns, foam generators, and other equipment, supporting manual/automatic control mode switching (interlock control available).
