PHP is an independent proportioning and mixing system that automatically adjusts according to flow and pressure. It is usually installed near the foam tank and connected to the foam tank, fire pressure water source and foam generating equipment through pipes. When a fire occurs, the foam pump starts to suck the foam from the foam tank into the proportioning mixer pipe. After being adjusted by the pressure balance valve and the proportioning mixer, a certain amount of foam is injected into the pressure water flowing through the proportioning mixer and forms a concentrate, which then flows to the foam generating equipment, such as foam guns, foam cannons, etc., and finally produces foam fire extinguishing.

Inline Balance Pressure Foam Proportioner (ILBP) is used with positive displacement foam concentrate supply pump. The system controls accurate flow of foam concentrate into the water stream over a wide range of flow rate and pressure.

The foam proportioning device is suitable for oil tank areas and refineries, petrochemical enterprises, hangars, port areas, cargo storage yards, warehouses, gas stations, paint storage areas, etc.

In Line Balanced Pressure Proportioning Systems (ILBP) allow the selection of either foam or water to every discharge device within the foam system.

The balanced foam proportion mixing device is a relatively advanced foam fire extinguishing device, which is particularly suitable for important fire fighting projects such as petrochemical enterprises, large oil depots, oil terminals and offshore drilling platforms.
