InnoVfoam has developed a foam proportioning system called “InnovDos” for adding foam concentrate to mains water without needing an external energy supply. InnovDos uses a water-driven foam pump. Its main components have been tested and approved by VdS. The system is suitable for foam proportioning in large (sprinkler) systems.

Its main components have been tested and approved by VdS. The system is suitable for foam proportioning in large (sprinkler) systems.
The InnovDos system provides accurate foam proportioning in sprinkler as well as deluge systems. The system consists of two main components (that can be separately integrated) and works without an external power supply by harnessing the water pressure in the extinguisher line via a bypass. The water pressure is delivered to the in-line turbine that is connected to a (geared) foam concentrate pump. This creates a suction effect on the inlet side and pumps foam concentrate to the proportion- er on the outlet side.
The proportioner, which is mounted on the extinguisher pipe, ensures that precisely the right per- centage of foam concentrate is injected into the system. Any overpressure in the foam feed line is correctly kept in balance by the membrane fitted inside the proportioner.
