FireDos: Market Leader Through Innovation

Many fire scenarios can be tackled successfully and effectively only if foam is used. To achieve this, a foam concentrate must be admixed to the extinguishing water at high precision. FireDos is a globally acting specialist in the design and production of high-quality foam proportioners and monitors for firefighting.

With its headquarters situated in Germany, the company developed an innovative admixing concept already more than 20 years ago, which consists of a water motor and a piston pump.

Beyond exact proportioning across a very wide operating range, the FireDos proportioners are characterized by an extremely eco-friendly working principle as no foam or premix is generated when testing the equipment. The focus on quality is an integral part of the company philosophy, proved by product approvals like the Europe-wide VdS accreditation or the international FM approval.

Beyond exact proportioning across a wide operating range, the FireDos proportioners are characterized by an eco-friendly working principle as no foam or premix is generated when testing the equipment.

The FireDos monitors‘ ‘Oval Flat Design’ ensures a longer reach of the extinguishing agent jet. They can be actuated manually or electrically remote-controlled.

GEN III - The next generation of FireDos proportioners

GEN III is the next evolution level of hydraulic foam proportioners for firefighting. Sturdier, smaller, safer and more functional: It makes operation more efficient and comfortable. The specially developed FireDos product concept has proven its safeness ten thousand times worldwide. This is what the newest generation GEN III will continue. The proportioner is a purely mechanic system and allows testing the proportioning rate in a cost-saving and eco-friendly way, producing no foam at all.

FireDos Monitors

The FireDos monitors’ octagonal ‘Oval Flat Design’ allows an even flow profile with minimized turbulence, resulting in only very low pressure loss. The extinguishing agent jet can therefore achieve an extended reach. The monitor portfolio is available with flow rates of up to 60 000 liters per minute (15 850 gpm) and a range of 180 meters (590 ft). Optionally, it allows a continuous adjustment of the water flow rate during operation. The monitors can be actuated either manually or electrically.

GEN III - The next generation

FireDos – the creator and technical market leader of the globally known water-driven foam agent proportioners for firefighting is presenting the next level of evolution. The original concept consisting of a water motor and a piston pump for all types, including extremely high-viscous alcohol-resistant and fluorine-free foam agents, has been further developed. FireDos has delivered more than 12 000 units to customers worldwide. All of them value the products’ quality, reliability, longevity and efficiency. We now proudly announce the new generation of FireDos proportioners:

GEN III is characterised by:


  • PRESSURE LOSS REDUCTION by approx. 25% due to hydraulic optimisation by computational fluid dynamics simulation.

  • FURTHER IMPROVED HANDLING OF FLUORINE-FREE FOAM AGENTS, through notably better suction capacity.

  • IMPROVED 2ND GENERATION CYLINDER CUT-OFF for selecting the proportioning rate – with increased accuracy even under extreme system conditions.
