GEN III FOAM PROPORTIONERS FOR FIRE EXTINGUISHING SYSTEMS: REDUCING COSTS, ENHANCING PERFORMANCE.

GEN III is the next level evolution of hydraulically driven foam proportioners for firefighting. Sturdier, safer, more functional: GEN III has many improvements, making their application in foam extinguishing systems more efficient and easier to use.

The product concept, specially developed by FireDos isproven many times in real-life applications. It is also the centerpiece of the latest generation GEN III. The advantages:

  • Risk reduction
  • Lower cost of ownership
  • Better performance

Typical fields of application for the GEN III proportioners are in industries such as logistics, chemical, oil & gas, as well as automotive, aviation and marine. In addition, foam agents are increasingly used for firefighting in waste incineration and sorting plants.

A UNIQUE PRODUCT CONCEPT: FOAM PROPORTIONERS FROM FIREDOS.

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 an extinguishing system. The purely mechanical concept consists of a water motor and piston pump, featuring absolute functional safety. It is capable of handling all types of foam concentrates, even highly viscous, alcohol-resistant and fluorine-free foam agents. A constant proportioning rate across a wide operating range guarantees safe proportioning and efficient firefighting in every situation. The purely mechanical system provides a cost-efficient and eco-friendly proportioning rate testing, completely without foam.

The typical FireDos advantages remain:

Optional Equipment.

Flow directions of the water motor

FireDos proportioners are available with four different flow directions to suit a wide variety of installation conditions.

Revolution counter with flow rate display for the extinguishing water

The water motor's number of revolutions is counted with the help of an optional proximity switch. The current extinguishing water flow rate is calculated from the number of revolutions and shown on an LED display in l/min.

Cylinder cut-off

To reduce the proportioning rate, an optional cylinder cut-off can be added to the proportioner. This means a cylinder of the proportioning pump is switched to bypass mode. One or more cylinders will then no longer inject the foam agent into the extinguishing water flow but pass it back to the suction side of the proportioning pump. The proportioning rate is reduced accordingly.

Seawater version

For use with seawater, a version with correspondingly adapted materials is available.

Flanges

Depending on the type series, the proportioner's flanges are threaded or firmly integrated in the housing. All flanges are available as DIN and ANSI versions.

Version for static pressure > 16 bar

In static mode, if the maximum permissible pressure of 16 bar is exceeded, particular components in the water motor can be adapted. This allows them to handle a static pressure of up to 25 bar.

Surge protection

When water surges occur, i.e. when empty pipework is filled after an alarm activation, there are multiple possibilities to protect the pipework as well as the FireDos proportioners. One option is the use of an automatic surge protection valve. This also prevents the potential damage caused by overspeed and water hammer.

ATEX version

With a declaration of confirmity according to 2014/34/EU. Marking: II 2G Ex h IIC T4 Gb / II 2D Ex h IIIC T130°C Db

Version for operating temperatures over 50 °C

Use of a special rotor vane variant enables higher temperatures of up to 80 °C.

Pressure sustaining valve with or without flow meter

When determining the foam agent flow rate in testing mode, it is important to simulate the real pressure conditions in the extinguishing system. The pressure sustaining valve installed in the return line is used to set a defined backpressure. To measure the volumetric foam agent flow rate, it is useful to additionally install a magnetic-inductive flow meter which measures the extinguishing agent flow rate and allows determining the proportioning rate.

Parallel installation

To extend the operating range of a FireDos proportioner, it is possible to install two or more proportioners in parallel.

With a proportional control valve:
The proportional control valve is installed upstream of one proportioner. Typical applications include Wet sprinkler systems.

Without a proportional control valve:
Parallel installations without a proportional control valve have a different operating range. This type of parallel installation is suitable for all fire protection systems with open discharge devices.

Electrically actuated ball valves

For integration in an on-site control system, the ball valves of the proportioner can be fitted with electric actuators.

 

Electrical ball valve position monitoring

As an optional feature, a switch can be added for electrical monitoring of the ball valve position.
