Vertical Foam Bladder Tank

The vertical foam bladder tank is widely used for extinguishing Class A, B, and C liquid fires, offering advantages such as small footprint and easy zone protection. They are available in carbon steel, titanium steel, and stainless steel, allowing selection based on specific needs. Their working principle involves a pump supplying pressurized water. As the pressurized water flows through a proportioner, a portion (3%-6%) enters the foam liquid storage tank through a branch pipe (inlet pipe), compressing the bladder and displacing an equal amount of foam liquid, which is then discharged from the outlet. This foam liquid mixes with the remaining water (97%-94%) within the proportioner, forming a foam-water mixture that is supplied to the foam generator at the end to produce air foam for fire extinguishing. Because the bladder separates the foam liquid from the water, any unused foam liquid can be reused, and the mixing accuracy is stable and reliable.

Why choose us?

FUXEON®'s vertical bladder tank is made of high-quality carbon steel, making it robust, durable, and corrosion-resistant; other manufacturers may use ordinary plastics or low-quality steel, which are prone to aging and corrosion. Our welding process is superb, resulting in smooth welds and meticulous attention to detail at weld joints. Other manufacturers produce rough welds with poor attention to detail, leading to leaks or structural loosening at weld joints.

FUXEON®'s bladder tank foam paint film adheres firmly to the surface of the foam tank, resisting peeling and cracking, and offering excellent abrasion resistance, able to withstand minor everyday scratches. Some manufacturers use inferior paint, which produces a poor film with low adhesion. After one or two years of use, the surface is prone to wear, peeling, and flaking, making it difficult to maintain a smooth and delicate finish.

Maintenance and upkeep:

Before using the bladder tank foam system, the sealing of the flange cover and connecting pipe flanges should be checked. After each use, the inside of the tank and pipelines must be thoroughly rinsed with clean water, and the inner and outer surfaces should be touched up with paint for corrosion protection. When filling with foam concentrate, the correct model must be used, and the tank must be kept clean. Mixing with oils, other foam concentrates, or aged concentrates is strictly prohibited. Furthermore, a simulation test should be conducted each time the foam concentrate is changed to ensure that the proportioning device and foam generator are functioning correctly and reliably. It is particularly important that tanks with diaphragms undergo a leak test every six months. During the test, the inlet valve should be opened; if foam leakage is detected, it indicates damage to the diaphragm, which should be repaired or replaced immediately.

How to clean the capsules in a foam bladder tank?

Drain the remaining foam liquid from the capsule, then open the water inlet valve, and then connect compressed air (pressure 0.02-0.1 MPa) through the vent valve of the capsule. Open the drain valve at the bottom of the tank to blow out the residual foam liquid in the capsule, then fill it with clean water to rinse the surface, and then use compressed air to dry the water before refilling with foam liquid.
