Stationary proportioners for extinguishing systems.

PRODUCT CONCEPT.

Many fire scenarios require foam for successful extinguishing. To produce these extinguishing agents, the foam agent must be admixed to the water flow at high precision. This is what makes the FireDos product concept outstanding: The specially designed water motors and proportioning pumps of the foam proportioners work flow-proportionally, allowing precise proportioning across a wide range of water flow rates and pressures. Furthermore, the proportioners allow a cost-saving and eco-friendly testing of the proportioning rate while no foam or premix is actually produced. Typical application fields are any place where flammable substances, particularly fluids, are produced, transported, stored or disposed of. This includes extinguishing systems for tank farms, jetties, hangars, high-rack warehouses or pump rooms.

GEN III - THE LATEST GENERATION OF PROPORTIONERS.

The FireDos product concept has been optimised, resulting in GEN III, the latest generation of proportioning systems. GEN III is characterised, among others, by more compact dimensions, reduced pressure loss, improved cylinder cut-off and optimised delivery of highly viscous and pseudoplastic foam agents.

FireDos foam proportioners: purely mechanical, with a constant proportioning rate.


  • The water motor (1) is driven by the extinguishing water flow which passes through it.
  • In turn, the water motor drives the proportioning pump (2). This pump pulls in the foam agent and delivers it into the extinguishing water pipework.
  • Switching between actual proportioning of the foam agent and passing it back to the atmospheric storage tank is done by use of the ball valve (3).
