FireDos presents the next generation of mobile positive pressure foam systems FD-DZ. The feature: The new unit works with an admixing rate adjustable in steps of 0.3%, 0.7%, 1%, 2% and 3%. Thereby all extinguishing agents form low surface tension water to foam are possible.
The minimum flow is 100 l/min, the maximum flow 1.000 l/min. Under all operation conditions the quality of the foam is equal. Changing flow rates, changing pressure and back pressure or different viscosities do not influence the function of the units. All systems designed by FireDos will be driven by the flow of extinguishing water without any external power.
