Production of CAF foam

CAFS stands for Compressed Air Foam System and is a system for the production of high-quality CAF (Compressed Air Foam), which is used to fight solid and liquid fires.

 

In the production of CAF, the same three components are required (water, foam compound and air) as in the generation of conventional fire fighting foam. The crucial difference lies in the foam expansion of the water-foam compound mixture, which in the CAFS system does not take place passively through the injector principle on the nozzle, but rather actively in a mixing chamber in the system by means of compressed air.

 

Due to this active foam expansion, the resulting CAF foam has a more homogeneous foam structure as well as a much higher energy content in comparison with conventional fire fighting foam.

Properties of CAF foam

  • Excellent throw range as well as superb throw height due to the increased energy value of the CAF foam.
  • Excellent adhesion of the CAF foam to smooth and vertical surfaces as well as first-class foam stability due to the fine and homogeneous foam structure.

Mode of action of CAF foam

During active foam expansion, a single water drop is distributed across multiple foam bubbles, which results in a larger surface area for heat absorption. Furthermore, the CAF foam sticks to the flammable material thanks to its homogeneous structure and thus enables continuous heat absorption. As a result, a large part of the water bound in the CAF is able to evaporate, thus providing maximum cooling at the seat of the fire.

 

The oxygen is displaced from the flammable material through evaporation of the water. Additionally, a natural separating layer is created between the flammable material and the oxygen as a result of the CAF. Thus the oxygen supply to the seat of the fire is interrupted in the best possible way.

 

Due to the high kinetic energy of the CAF foam and the reduction of surface tension through the added foam compound, water can penetrate deeper into the flammable material and thus soak in better.
