Proportioning Equipment introduces a foam concentrate into a flowing stream of water to produce a foam solution. There are many methods of proportioning, but fixed foam systems typically use balanced pressure proportioning equipment such as the In-Line Balanced Pressure Proportioner. This proportioner is similar to a pump skid except it is a separate assembly that offers the advantage of proportioning the foam concentrate at a location remote from the tank and pump.

In-line balanced pressure proportioners are used with an atmospheric foam concentrate tank and a positive displacement foam concentrate pump. They are designed to accurately control the flow of a foam liquid concentrate into a water stream over a wide range of flow rates and pressures. These devices can be used with all types of ANSUL foam concentrates.

Multiple in-line balanced pressure proportioners can be supplied from a single foam pump to protect several hazard areas. By adding an automated valve to each proportioner, either foam discharge or water-only discharge can be selected.

The units are available in six standard sizes to supply proportioners ranging from 2 to 8 inches with flow rates from 30 to 5,500 gpm (114 to 2,082 Lpm).
