Rosenbauer POLY extinguishing systems
Independent. Innovative. User-friendly.
Principle of operation of the POLY extinguishing
system with the unique Admix system
After opening the compressed air bottle (1), the com-
pressed air flows into the extinguishing agent tank (2) as
well as into the separate foam compound cartridge (3)
and brings them up to a constant working pressure.
After activation of the CAFS nozzle (4), the water in the
extinguishing agent tank is forced into the riser tube (5),
and the foam compound located in the separate foam
compound cartridge (3) is continuously mixed with the
water in the admix mixing chamber (6).
Subsequently, the water-foam compound mixture that
is produced in the CAFS mixing chamber (7) is actively
made into CAFS foam (compressed air foam) with the
compressed air located in the extinguishing agent tank
and is discharged via the CAFS nozzle (4).
