Description Atmospherical Foam Concentrate Tank

An atmospheric foam concentrate tank is one component of a foam proportioning system. The Sabo Española foam tanks are compatible with all foam concentrate.
An atmospheric concentrate tank is typically used in conjunction with a Sabo Espanola “balanced pressure proportioner like the model SE-VZ, with the in- line proportioner or with a volumetric dosing system. Storage tanks shall be designed for storage of foam concentrate at atmospheric pressure and shall be available in vertical or horizontal version.
The Sabo Española produces two type of tanks with two different construction material; the model A is made by Polypropylene homopolymer PPH, UV stabilized and it be used for fixed installations for standard use, while the model SE-DA is made by carbon steel material (stainless steel material as OPTIONAL) and generally it is used together with an in-line proportioner or where the Polypropylene tank model SE-A is not a proper solution.

Installation requeriments

The foam concentrate storage tank shall have a minimum capacity to provide sufficient foam concentrate for the time specified when the system is discharging foam solution at total maximum system flow.
If it is used a carbon or stainless steel tank type SE-DA with AFFF type foam concentrate, Sabo Española does not recommend lining the inside tank shell. The reason is that the tank and the liner have different coefficient expansion ratios during various ambient temperature cycles. Over time pinholes may occur in the lining. AFFFs having a very good wetting ability will penetrate the pinholes and get in between the lining and the tank shell.
Eventually portion of the lining may flake off and travel into the foam concentrate system, subsequently blocking orifices, strainers, etc. Upon receipt of your order and before any installation, inspect the tank for any damage that may have occurred during shipping to trim valves, piping, etc. When using AFFF or AR-AFFF type foam concentrate in any atmospheric type storage tank, it is recommended by Sabo Española that a thin layer, approximately 5 mm ( 0,20 inch) of a quality mineral oil be placed on surface of the foam concentrate after filling the tank with the correct quantity. This alleviates the problem associated with evaporation of the foam concentrate.
If any AFFF concentrate spills on any painted surface during any filling of the storage tank(s), immediately wash the area with water. The solvents in the AFFF may cause streaking of any painted surface.
It is recommended that when using non-freeze protected foam concentrates, that the foam tanks be located in an area that is kept between 1,5 °C – 50 °C(34,7°F – 122°F).

Installation

If the tank has been received in any satisfactory condition, place the tank in the desired level location and if necessary, anchor to the floor. If possible, leave an area around the tank free from any walls, obstacles, etc. This given working space for connecting the foam system piping to/from the tank.

Inspections, maintenance and tests

Check the status of foam concentrate. (See constructor indications).

Tank with lining protection

Check the status of the painting of tank, if necessary replace with a new coat, to prevent atmospheric corrosion.
