ORDERING INFORMATION Please specify 1) Tank type, vertical or horizontal 2) Storage capacity of foam concentrate 3) Model number, size of ratio controller with flow and pressure. 4) Type of foam concentrate to be used and percentage of induction required. APPLICATION 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. SPECIFICATION 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. PRINCIPAL OF OPERATION The foam concentrate is to be filled into the bladder very carefully to avoid rupture of the bladder. The instructions for filling are provided with the equipment. Once the main water flow is established and water inlet and foam outlet valves are opened, the water

FIREGUARD SAFETY EQUIPMENT CO. LTD. www.fireguard-uk.com Fireguard Bladder Tank Proportioning System enters the area between vessel wall and bladder, applying pressure to the bladder. The foam concentrate is forced out of the bladder through the foam outlet pipe and into the ratio controller through metering orifice. The concentrate pressure and water inlet pressure at ratio controller will be same, as the main water supply pressure is utilised to expel the foam from the bladder. The water flowing through the ratio controller jet creates a low pressure area common both to down stream water...
