Digifoam is a digitally controlled, fully automatic Around-the-Pump foam proportioning system designed to maintain a constant and accurate foam-water ratio, regardless of water flow or pressure fluctuations
Using the proven Around-the-Pump principle, Digifoam makes the foam solution available through the complete discharge system, ensuring reliable foam performance at every outlet.
The Digifoam DF system is typically operated through a large 7” LCD HMI, providing clear and intuitive control of all system functions. The display gives the operator an easy overview of key process data, including water flow, foam flow, proportioning rate, warnings and error messages.
Alternatively, the DIGIFOAM function can be integrated directly into the PCU Pump Control Unit with built-in foam management, eliminating the need for a separate HMI in certain system configurations.
Remote HMI units can be added for control from multiple locations, including the driver’s cabin.
