Reducing costs, enhancing performance
STATIONARY PROPORTIONING SYSTEMS FOR FIRE EXTINGUISHING SYSTEMS
Our stationary proportioners are a key element to industrial fire extinguishing systems. Operators worldwide rely on our purely mechanical equipment – which is independent of electricity and emergency power supply – if it is about precise and reliable foam agent proportioning into the extinguishing water.
All foam agent types, even such ones of high viscosity, can be mixed. A constant proportioning rate across a wide operating range guarantees automatic adaptation to variable firefighting scenarios. Another advantage: The cost-effective and eco-friendly proportioning rate testing method works completely without producing foam or premix.
- Also suitable for high-viscosity foam agents
- For water flow rates from 70 to 25 000 l/min
- Available for proportioning rates of 0.5 %, 1 %, 3 %, 3+3 % and 6 %
Proportioning rate testing without foam: cost-effective and eco-friendly
Constant proportioning rate across a wide operating range
a unique product concept: proportioners from firedos for firefighting with foam
The product concept by FireDos allows operators to more than just minimize risks; it also facilitates a reduction in costs and enhances the performance of a fire extinguishing system.
PURELY MECHANICAL, HIGH RELIABILITY
The purely mechanical concept consists of a water motor and piston pump, featuring absolute functional safety. Driven just by the water flow, no electricity and no backup power supply is required.
- UNLIMITED FIRE-FIGHTING TIME
As the separate foam agent tank is unpressurised and can therefore be refilled whenever necessary, users benefit from unlimited fire-fighting time.
- FOR ALL FOAM AGENT TYPES
It is capable of handling all types of foam concentrates, even highly viscous, alcohol-resistant and fluorine-free foam agents.
- FOR ALL TYPES OF FIRE EXTINGUISHING SYSTEMS
Thanks to the wide operating range, the proportioning systems are qualified for all types of fire extinguishing systems like sprinkler, deluge, wet and dry extinguishing systems.
- CONSTANT PROPORTIONING RATE
A constant proportioning rate across a wide operating range guarantees safe proportioning and efficient firefighting in every situation.
- TESTING THE PROPORTIONING RATE WITHOUT FIRE FIGHTING FOAM OR PREMIX
The purely mechanical system provides a cost-efficient and eco-friendly proportioning rate testing, completely without fire fighting foam.
Stationary proportioners for extinguishing systems, sprinkler and deluge systems
Our stationary proportioning systems are applied in sprinkler and deluge systems, wet and dry extinguishing systems. Typical fields of application are wherever flammable substances, particularly liquids, are produced, transported, stored or disposed of - be it in fire extinguishing systems for tank farms, jetties, hangars, high-rack warehouses or pump rooms. In addition, foam agents are increasingly used for firefighting in waste incineration and sorting plants.

Testing the proportioning rate without premix and fire fighting foam: eco-friendly and cost-effective
Fire extinguishing systems must be tested regularly to ensure their functionality in case of fire. The same applies for the proportioning system. The return line connection enables return of the foam agent back into the foam agent tank under live operating conditions while its volumetric flow rate is measured. The results of this and the measured quantity of water which passes through the unit at the same time are used to calculate the proportioning rate. While doing so, no premix or fire fighting foam is produced.
This is how easy testing can be:
- The testing cycle can be activated via the ball valve 'Returning / Proportioning'.
- While the extinguishing water is circulating, the flow rate is measured.
The water motor drives the proportioning pump in a direct ratio to the extinguishing water.
- Foam agent is circulated and measured by a magnetic-inductive flow meter.
- The proportioning rate can be calculated.
