SRI - FM200

Cerberus® FM200 The better extinguishing performance due to high pressure technology The faster extinguishing effect of Cerberus® FM200 as compared with conventional low pressure FM200 systems is achieved solely by means of the high-pressure technology which the Siemens Cerberus Division developed for Halon 1301.

Fig. 1 : advantage of high pressure nozzle

By high-pressure technology, we understand a minimum operating pressure at the nozzle of 10 bar as well as an FM200 storage pressure of 42 bar. Both high-pressure criteria together are vital for the rapid and reliable extinguishing of a fire with FM200 :

� Rapid release of FM200 in the extinguishing sector. � Total vaporization aIready during flooding. � Perfect homogenization before flooding is completed.

Only when all three of these criteria are completely fulfilled is the FM200 gas available immediately after flooding in each part of the extinguishing sector in the required extinguishing concentration to extinguish a fire reliably in the shortest possible time.The results of numerous extinguishing tests in our laboratories have shown that as a rule, a fire can be extinguished in less than 30 seconds after the system has been actuated.

Minimum operating pressure of 10 bar at the nozzleFM200 is transported in liquid form to the nozzles in the extinguishing sector where FM200 is atomized. Energy is required for vaporization and must be supplied to the droplets. As fig. 1 shows, the ambient air is drawn into the FM200 droplets / nitrogen jet which provides the necessary energy for vaporization. On account of the distinctly higher impetus of the jet at a higher operating pressure at the nozzle, with conventional low-pressure systems, less energy is transported for droplet vaporization in the jet, although more energy is required for rapid vaporization of the larger FM200 droplets (see fig. 1).The droplet size, arising from atomization of FM200, decreases with increasing operating pressure at the nozzle. With simple thermodynamic calculations, it is possible to work out the life of an FM200 droplet expressed as the distance travelled in metres as a function of the operating pressure at the nozzle (see Table 1). The results presented in Table 1, clearly show that only at a minimum operating pressure of 10 bar is an FM200 droplet completely vaporized before it can collide with any object in the extinguishing sector. For this reason, with a high-pressure system, a delay until all the FM200 is totally vaporized under unfavourable thermodynamic conditions upon completion of the flooding process, is impossible.



FM200 storage pressure of 42 barThe Cerberus® FM200 high-pressure technology guarantees that for each kilogram of stored FM200, more nitrogen propelIant is available with which even with larger and more complex applications, the maximum filling factors can be realized (see fig. 2) by comparison with conventional systems and so optimizes the ratio of hardware required to each stored kilogram of FM200. While nitrogen in the cylinder head via the FM200 liquid surface serves to fill the pipe network with liquid FM200 and to initiate atomization at the nozzle, the nitrogen dissolved in the FM200, which sustains the flooding of FM200 in the extinguishing sector, is crucial.

Fig 2 : *) Filling factor dimension : kg FM200 per liter cylinder volume

Storage pressure 42 bar (20°C)

Temperature range -20°C to 50°C

Maximum nozzle room height coverage 5 m

Filling factor 0.45 to 1.15

Discharge time < 10 s

Extinguishing time < 30 s

Because of the rapid vaporization, the high pressure system able to achieve shorter extinguishing time compare to low pressure system, therefore the hydrogen fluoride (HF) normally generated by halocarbon agents in the presence of a fire is negligible for high pressure system.

We are also able to provide Room Integrity Test services to determine the leak tighness of a protected area without discharge of gas. The test is performed using portable devices comprising of pressure gauges, variable speed fans and a dedicated computer programme written to confirm to NFPA 2001 and 12A appendix B procedure.

TOTAL FLOODING SYSTEMS Total flooding systems extinguish fires by rapidly supplying an enclosed volume with enough FM200 to create an atmosphere that is incapable of supporting combustion. The systems is completely effective even in spaces with a limited amount of open area. By filling the entire space fire cannot exist on the floor, on the ceiling or at any level in between. Not matter how severe the flames may be they are normally extinguished in less than 30 second upon discharge.
