Indoor extinguishing systems

Protection of people, buildings and machinery

Stationary fire extinguishing systems protect people, buildings, machinery and flammable materials. The systems are based on the innovative CAF (compressed air foam) system. Extinguishing agent is distributed via full cone spray nozzles. The extinguishing system can be designed as a self-sufficient system (POLY) and then functions completely without external energy.
The indoor extinguishing system can be connected to a fire detection device and activates automatically in an emergency.

Impresses with

  • Highest extinguishing efficiency
  • Easily retrofittable
  • Energy-autonomous operation possible
"We cannot afford expensive production downtimes due to fire. We have plenty of orders and are operating at full capacity. Which is why we protect our business with extinguishing systems from Rosenbauer. They extinguish incipient fire immediately."
Tobias Frenzel CEO
Bharat Forge Aluminiumtechnik GmbH & Co. KG
"When decided to equip our facilities with stationary fire protection to protect the waste sorting plant and refuse derived fuel treatment plant, there was no optimum solution on the market yet. Because of the high risk of fire during the production process and the special requirements of the most modern treatment plant in the world, we have decided in favor of an energy independent extinguishing system and have found a reliable partner in Rosenbauer. This extinguishing system with compressed air foam constitutes the optimal protection."
Dietmar Joost Head of the Plant for the Treatment of Fuel Substitutes
Korn Recycling GmbH
"We are certain that with Rosenbauer at our side, we've found the perfect partner to help us achieve our fire protection goals. The concept they envisioned, whose viability was confirmed by a comprehensive series of tests and trials, and their unmatched experience with this kind of technology were what convinced us."
Ing. Andreas Prommegger Engineer and Saftey & Fire Protection Officer
Liebherr-Werk Bischofshofen GmbH
"Our Rosenbauer extinguishing system has been used several times and it has provided reliable protection. The project was a big investment, but one which has been well-worth it many times over, since machine and production downtimes from a fire are now a thing of the past."

CAFS (compressed air foam) has superior foam quality and highest extinguishing power with small quantities.

Under the influence of compressed air, a simple water-foam mixture will be mixed in the FLASH CAFS central unit into highly efficient CAF foam. The mixing chamber is protected against environmental influences, thus fire fumes cannot influence foam building.

The air required for foam expansion will be provided by compressed air bottles. In this way the system requires no external energy - it is completely self-sufficient.


CAFS enables fast and safe extinguishing for optimum plant protection.

  • Consistently stable foam quality
  • Foam sticks to hot surfaces - also vertically
  • Rapid smothering of the flames through oxygen deprivation
  • Deep penetration into the burning material by reducing the surface tension of water
  • Increased safety against back-burning and sustainable cooling through compact CAFS foam structure
  • Lower application rates for efficient fire fighting and limiting water damage
  • Extensive extinguishing agent quantity through active foam expansion to CAFS

The POLY system is a purely mechanical system made up of three main components:

  • Container with premix (water-foaming agent mixture)
  • FLASH CAFS central unit for the production of CAFS (compressed air foam)
  • Compressed air bottles to drive the system and for foam expansion

The firefighting system functions completely autonomously and requires no external energy – no pumps, engine or power. This way the system can be retrofitted easily.

The system will be activated automatically or via a fire detection system. Extinguishing agent output will then follow within seconds.

The full cone spray nozzle protects the entire area under the nozzle. The firefighting systems can be optimally adapted to the protection target by variable nozzle sizes. The opening angle of the nozzle is between 30° and 170°. Thanks to the use of nozzles with large outlet cross-sections no particular requirements are made on the fire fighting water. Special filters are not needed.
