Proportioning Systems

Proportioning systems mix foam concentrate with/in the water flow. Proportioners
Various types of foam proportioners can be used for precisely proportioning foam concentrate in the water-stream of an extinguishing system. The choice of proportioner depends on a number of factors such as the type of extinguishing system, the required capacity, the available energy, storage space (inside/outside/size) and the available pressure.
The purpose of the proportioning system is to ensure that the ratio of foam concentrate and water (the proportioning percentage) is correct. Once the correct proportioning percentage is determined, the amount of stock required for the concentrate can then be calculated.

  • InnovDos Foam Proportioning System

    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.
  • Electronic foam Proportioning system

    Accurate foam proportioning is critical in fire fighting applications. Regulations such as NFPA-11 show different ways for inducing foam concentrate at a foam fire fighting system. The innoVfoam Electronic Foam Proportioning System (EFPS) meets NFPA-11 regulations. This system is accurate, simple, compact and suitable for any type o foam concentrate or system. It’s wide flow range makes is suitable for both sprinkler and deluge applications. Thanks to our special InnoVfoam software, the system operates without dedicated electronically operated control valves. Special flow meter-operated speed control, combined with a VdS-approved gear pump, guarantees accurate operation within range.
