D-2 Automatic Mixer Systems
Automatic mixer systems are mixing equipment where firefighting water and foam concentrate are pressurized separately from each other, as typically used in refineries and storage terminals.
This section describes MA, MAP/M and MSC/M type mixers produced by C.S.I. S.r.l. to create accurate foam mixing where needed. This equipment regulates the pressurized foam concentrate flow by sensing the water pressure and changing the geometry of the foam concentrate passage.
All equipment described in this section requires that the foam concentrate supplied to the mixers should have a higher pressure than the expected maximum water pressure available at the inlet for the correct functioning of the equipment.
