Balanced Pressure Proportioning System

The Forede foam bladder tank stores foam concentrate and is a component in a balanced pressure proportioning foam system. A flexible concentrate bladder within the pressure tank contains the foam concentrate. The concentrate bladder physically separates stored concentrate from the water supply. When the system is activated, firewater supply pressure transmits the force through the flexible concentrate bladder, which forces the concentrate to the ratio flow controller. These bladder tanks do not require an external power, other than a supply of water to ensure proper operation. The tank inferior is sandblasted white and all welds and edges ground smooth. The tank shell water inlet is screened to prevent bladder blow out or the entrapment of debris between the tank shell and the bladder. All other openings greater than 1" are screened to prevent bladder blowout.
