FOAM PLANT

It is constituted by generators (in case of high expansion) whose purpose is to saturate the air; therefore the foam is injected in the room to saturate the environment; in case of sprinkler (low expansion) it has a double function: to cool and to saturate.
Advantages: it reduces the use of pipelines, it immediately prevents the possible propagation of flames.
Disadvantages: it needs surveing/activating system, post-operation local cleaning costs, system restoration costs (foaming agent, etc.).
