A fire suppression system includes a water supply, a foam concentrate supply, and a venturi-principle foam proportioner fluidly coupled to each of the water supply and the foam concentrate supply. The venturi-principle foam proportioner controls a ratio of water and foam concentrate within a low pressure chamber to form a water and foam solution flowing out of the venturi-principle foam proportioner. The system also includes a variable foam concentrate orifice fluidly coupling the foam concentrate line to the low pressure chamber. The variable foam concentrate orifice includes an actuator configured to adjust an orifice area of the variable foam concentrate orifice based on a temperature of the foam concentrate.

An apparatus, system, and method for firefighting foam in a bag is disclosed. A firefighting foam in a bag system includes a firefighting foam in a bag apparatus. The apparatus comprises an outer container configured to provide structural support and protection, an internal collapsible bag disposed within the outer container to store foam concentrate and collapse as the concentrate is dispensed, and a connection mechanism for detachably securing the internal collapsible bag within the outer container. The system further includes a foam proportioning device configured to mix the foam concentrate from the internal collapsible bag with water to create a foam solution, operatively connected to both the internal collapsible bag and a water supply. Additionally, the system includes a discharge device configured to apply the foam solution to a fire-affected area, operatively coupled to the foam proportioning device.
