How FireDos Foam Proportioners Work: A Simple Guide for Industrial Fire Protection
When seconds count, FireDos foam proportioners are the backbone of any industrial fire suppression system. But how do they actually work? And what makes systems like FireDos the gold standard in reliability and precision?
Whether you're running a fuel depot, a recycling plant, or a hangar, understanding how proportioners operate can help you make smarter safety decisions.
"Once the industry embraced FireDos technology and benefits, we began to successfully supply many projects covering a wide range of industries and applications."
Mike Feldon,
Managing Director of DoseTech
What Is a FireDos Foam Proportioner?
A FireDos foam proportioner is a device that mixes foam concentrate with water at a precise ratio before discharge. This foam-water mix is then applied to fires via end of line equipment which introduce air to create a foam, used to smother fuel, suppress vapours, and prevent re-ignition.
The goal? Consistent, reliable dosing — even in the most extreme conditions.
FireDos: The Non-Electric Difference
Traditional systems often depend on external power sources or complex pumps. FireDos foam proportioners are driven by the water flow only — meaning no electricity is needed.
Benefits of FireDos:
- Water Motor driven — works even during power loss
- Built-in testing without discharging foam
- High accuracy and flow adaptability
- Suitable for Class A and B fires

How It Works (In Simple Terms)
1. Water flows into the system during firefighting
2. The drive motor rotates, powered by the water flow
3. Foam concentrate is drawn from the tank
4. The system mixes foam + water at a precise ratio
5. The mixed foam is discharged via monitors, nozzles, or trailers etc
Why FireDos Proportioning Matters
If the foam is too lean — the fire may reignite. Too rich — you're wasting concentrate and Flowability (not a word any suggestions) . That’s why smart proportioners like FireDos are built for accuracy, consistency, and environmental responsibility.
Can You Test Without Wasting Foam?
Yes — with FireDos smart systems, you can perform flow tests without discharging foam concentrate. The unit simulates the mixing process, keeping your site compliant and eco-conscious.
Where FireDos Foam Proportioners Are Used?
- Fuel depots and tank farms
- Airports and helipads
- Warehouses with flammable goods
- Maritime docks and bunkering sites
- Waste processing and incineration
- Bulk flammable liquid distribution centers
