A foam tank is basically a large container of liquid foam concentrate containing a membrane made of synthetic material resistant to corrosive foaming agents and equipped with a foam dispenser.
Depending on where the foam concentrate is contained, it is possible to differentiate between:
The foam bladder tank serves as a dosing system through a very simple mechanism: water from the water network pressurizes the tank, pushing the foam concentrate contained therein into a Venturi-type foam dispenser. Here, the foam concentrate comes into contact with the water, forming the foam mixture that will be channeled to the distribution network pipe.
A foam tank can have variable sizes and, consequently, different capacities to hold foam concentrate. It is capable of operating even at relatively low pressures and ensures minimal pressure losses. In addition, the dispenser applied to it can be calibrated according to the flow rate and the percentage of mixture required in the system (usually at 1%, 3% or 6%).
The foam dispenser can be a standard model FI-PM or a wide range type FI-WRM, with a huge range between minimum and maximum flow rates, which is commonly used for foam sprinkler systems.
Fierre foam tanks are manufactured in accordance with 2014/68/UE, ASME VIII DIV. I and are available UL listed.
In addition, Fierre can supply foam tanks on request. U-STAMP ASME.
