The Bladder Tank Foam Proportioning Systems are available with vertical and horizontal bladder tanks. The carbon steel tanks are designed and constructed in accordance with ASME Code Section VIII Div.1 for unfired pressure vessels. ‘U’ stamp and/or CE mark is optional.

The maximum working pressure is 12 Bar (175 PSI), unless higher working pressure is ordered. The vertical tank assembly is supported by legs welded to the tank with provision for anchoring. The horizontal tanks are supported by two saddles/legs welded to the tank and drilled for anchoring. Tank is provided with lifting lugs, designed to use with empty tanks.

The system is supplied with pressure vessel, bladder, fill and drain valve for water and foam concentrate, ratio controller and vent valve. Ladder and sight gauge assembly are supplied as optional items on request.

All valves are labeled showing normal working position and function.

All tanks are oversized for allowing thermal expansion of the foam concentrate, if any.
Some of valves, one side is plugged or blank flange is bolted. This is to avoid Foam Concentrate leakage with accidental opening of valve.
