Installation of the FoamTronic in a live production area at BASF Antwerp

BASF Antwerp is a large site with ±50 different production and/or storage facilities for various chemical products. This is a challenge for the fire brigade and other emergency respons teams.The fire department of BASF is very well equipped and trained to cope with challenging fires involving hazardous chemicals. Safety is of the highest priority at BASF.

A study was performed regarding two tank pits with four large tanks and seven smaller tanks.

The outcome of the initial risk assessment was the following:

  • The smallest tanks can be cooled and/or extinguished using mobile equipment;
  • The large storage tanks (ø 50m) need a fixed cooling and foam suppression system;
  • The bund areas need a fixed foam suppression system.

The challenge was to install all new piping and keep the functionality of the existing fire extinguishing system as long as possible. This has been successfully completed and the system now includes additional connections to feed mobile equipment with large capacity.

FoamTronic is an electronic foam mixing system which very accurately mixes foam concentrate and water based on the actual firewater demand of the system. This is achieved by continuous monitoring of the firewater and foam concentrate flows using electromagnetic flowmeters and real-time adjustment of the concentrate control valve. An advantage of the FoamTronic system is that there is no pressure loss in the water supply towards the extinguishing systems. There is only an electromagnetic flow meter installed in the water pipe of the manifold. As a result the new piping diameters could be reduced.

Classic foam proportioners require to be tested mixing water and foam concentrate to ensure the proper mixing ratio.

Testing of the mixing ratio for mechanical proportioners would create enormous amounts of waste water, use large amounts of foam concentrate and, as a consequence result in serious financial loss.

FoamTronic allows system performance to be regularly tested without mixing foam and water, thus avoiding environmental concerns and depletion of costly foam stocks. By using a FoamTronic foam proportioner the cost for annual system testing and the impact on the environment has been reduced significantly.

In cooperation with our sister company Knowsley SK we have delivered the FoamTronic delivered as a skid, ready to put in place at the project.

New manifold

The new manifold is located near the tank pit, behind a fire-resistant concrete housing.

After placing and testing the new manifold, the areas where the pipes were to be renewed are divided into smaller zones. The zones were temporarily protected during the work with large mobile monitors. These monitors were connected to the new manifold.


All systems have been tested thoroughly to ensure proper operation. One part was testing the FoamTronic foam proportioner.  The tests were carried out without using foam concentrate. The foam concentrate was collected in a cleaned tanker for re-use.

By implementing the FoamTronic system, we were able to significantly

reduce the total project costs. This has been achieved by allowing the reduction of the pipe diameters within the system. In addition, during commissioning tests we did not use foam concentrate. In the future, the savings will be realized each year by the low costs of the periodic tests and maintenance activities.
