Various types of foam proportioners for precisely proportioning foam concentrate in the water-stream of an extinguishing system can be used. The choice of proportioner depends on a number of factors: the type of extinguishing system, the required capacity, and the available energy, space (inside/outside/size) and pressure.Matre Balanced Wide Range Proportioner inserts foam concentrate into water over a very wide water capacity range. Standard insertion rates are 1%, 3%.
Matre Balanced Wide Range Proportioner is a wafer type mounted between ANSI or DIN flanges in the water line.
The concentrate is supplied to the proportioner by a foam concentrate pump. Pressure of foam concentrate shall be at least 1,2 bar above water inlet pressure. Max. differential pressure between water and foam concentrate is 5 bar.
Standard material is high quality seawater resistant bronze.
