FireDos GEN III foam proportioners: reduce costs, increase performance

FireDos GEN III is the next level evolution of hydraulically driven foam proportioners for fire fighting. Sturdier, safer, more functional: GEN III has many improvements, making their application in foam extinguishing systems more efficient and easier to use. The purely mechanical product concept developed by FireDos, consisting of a water motor and piston pump, has been extensively optimised. GEN III is characterised by more compact dimensions, lower pressure loss, improved cylinder shut-off and optimum delivery of highly viscous, even fluorine-free foam concentrate. Users benefit from maximum safety, cost reduction and an increase in performance. With FM approval, the units meet one of the highest quality and safety standards worldwide. The proportioning rate is always constant and independent of the water flow rate or pressure, allowing optimum automatic adjustment to varying fire fighting scenarios. Benefits include: sturdier design, long service life and ruggedness, pressure loss reduction by 25 percent, hydraulic optimisation, improved cylinder cut-off, increased precision also under extreme system conditions, optimised delivery of high-viscous foam agents and improved suction capacity.
 
The working principles are:

• The extinguishing water drives the water motor so no need for electrical or emergency power supply .
• The water motor, via a coupling, drives the proportioning pump. This pumps foam agent (all foam concentrate types, including also highly viscous and fluorine-free) and into the extinguishing water line.
• The ball valve enables switching between the injection of the foam agent into the extinguishing water flow or return to the foam tank. Returning the foam agent to the tank is for testing the proportioning rate. No premix or foam is generated and no foam agent is consumed.

 
Testing the Gen III’s proportioning rate without premix or foam production is both environmentally safe and cost-efficient, saving on foam and disposal costs.
 
Typical fields of application for the GEN III proportioners are industrial, logistics, chemical, oil and gas, as well as automotive, aviation, pharmaceutical and marine.
