Foam Proportioners (Matre Maskin Norway)
The foam proportioner starts to function as soon as water starts to flow through it. For testing purposes or to run the system with water only it is possible to choose whether to mix in foam or to send it in return to the tank. This represents a substantial economical and enviromental saving and at the same time increasing safety. It also helps to simplify the firefighting system as auxiliary valves can be omitted.
