Fire-fighting foam tank
The bladder pool foam balancing system uses water pressure⭐ to inject concentrated foam the water source and automatically proportions foam concentrates
✅ over a wide range of flow and pressure, with very low pressure drop . This system does not require a centralized supply pump.
The bladder pool foam ratio system is available with vertical and horizontal bladder tanks. The carbon steel tanks are designed and constructed in accordance with ASME Code Part VIII for pressure vessels. Maximum working pressure is 12 Bar (175 psi) and factory tested for 18 Bar (261 psi). The vertical tank assembly is supported by a continuous skirt with redundancy for anchors. The horizontal tanks are supported by two saddles welded to the tank and drilled for anchorage. Tanks are supplied with lifting lugs.
The system is provided with pressure vessel, bladder, filling and draining valve for water and foam concentrate, proportional controller and vent valve. Steps and glass assemblies are available as optional items upon request.
