The Bladder Tank Foam Proportioning System utilises the water pressure to inject foam concentrate into a water supply and automatically proportions foam concentrate over wide range of flow and pressure, with very low pressure drop. This system does not require concentrate supply pump.
The Bladder Tank Foam Proportioning System are available with vertical and horizontal bladder tanks. The carbon steel tanks are designed and constructed in accordance with ASME Code Section VIII for unfired pressure vessels. The 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 provision for anchoring. The horizontal tanks are supported by two saddles welded to the tank and drilled for anchoring. Tank is provided with lifting lugs.
The system is supplied with pressure vessel, bladder, fill and drain valve for water and foam concentrate, ratio controller and vent valve. The ladder and sight glass assembly is supplied as optional item on request.
