UL Listed bladder tank foam proportioning system that uses water pressure to automatically inject and proportion foam concentrate into the water supply across a wide range of flow rates and pressures — with no concentrate supply pump required. The internal thermoplastic bladder separates the foam concentrate from the pressurising water, ensuring accurate proportioning as the water pressure forces concentrate through the ratio controller metering orifice.

Available in vertical and horizontal configurations, the carbon steel pressure vessel is designed and constructed in accordance with ASME Code Section VIII for unfired pressure vessels, making it suitable for demanding industrial and petrochemical fire protection applications.
