Abstract:
A compressed air foam delivery system includes a control unit to monitor and/or adjust components within the system so as to deliver a compressed air foam agent mixture with a desired agent:air ratio at a desired flow rate to one or more active discharges. In one embodiment, the control unit can be equipped to control one or more of a pump engine, water pump, foam delivery unit and air compressor so as to deliver and maintain the desired ratio of agent mixture at the desired flow rate.
