Foamtronic: testing a foam extinguishing system without mixing foam concentrate

  • 19 November 2019

To comply with the standard, like the NFPA 11, the operation of a foam extinguishing system must be tested annually with a live test. A large amount of foam concentrate is used for this test. This is not only harmful for the environment, but also expensive for the owner. It is not only the purchase value of the foam concentrate, but also the additional hidden costs after the test. The foam must be collected, and disposed of correctly.

Reducing both the environmental pollution and costs for our customers was our drive for the development of the foam proportioning system: FoamTronic.


The FoamTronic is an electronic foam mixing system that accurately mixes water and foam concentrate. Due to the accuracy of the foam proportioner, the volume of the foam supply can remain limited. FoamTronic is available in flow rates ranging from 150 liters per minute to 450,000 liters per minute.

The major advantage of the FoamTronic is the ability to test the performance of the foam extinguishing system without mixing foam concentrate and water. This means that no waste is produced and the environment is not unnecessarily burdened. In addition, unnecessary use of foam concentrate is prevented resulting in costs being saved.


There is no pressure loss in the water supply towards the system because a flow meter is installed in the pipe. In many cases, the pipes can therefore be made smaller (in diameter).


Every component of the system has continuous signal monitoring and performs self-diagnostics. In addition, the flow control valve is tested daily automatically and the performance of the check valve in the foam concentrate supply line is monitored for leak free operation.
The control system has an intuitive graphic user interface, specially developed for FoamTronic, it records and shows all data.


The cabinet is designed for the harshest environments, it’s manufactured from stainless steel and powder coated to ensure maximum corrosion protection. The complete assembly is preassembled using high quality components. Options such as cabinet heating and insulation are available.

It is possible to integrate the FoamTronic into new and existing foam extinguishing systems.
