CO2 normally has no colour, no odour and it looks like a white vapour when
discharged; it is not corrosive, it causes no damage at all to any material and it does not wet anything.
Carbon dioxide, unlike air, does not contain a
sufficient amount of oxygen for combustion; it evaporates rapidly
without leaving any kinds of residue and causing a significant decrease
in temperature, a factor which notably increases the extinguishing
effect of CO2.
Humans cannot breathe in an environment that is
saturated with CO2 and, therefore, the appropriate precautions must be
taken before entering an environment where this gas has been discharged
in large quantities.
The fire fighting system uses carbon dioxide in its
liquid state, stored in cylinders with a pressure of about 55 bar at
15°, as an extinguishing agent.
The system's operation is completely automatic, thanks
to the innovation with which the discharge of the extinguisher is
determined by the electrical control panel, as well as the special
controls and automatic valves.
In addition to the automatic mode, the machine can also
be operated manually. The size of the system and the quantities of CO2
are appropriately calculated in accordance with NFPA 12.
CO2 systems are both total flooding as well as local application systems for the specific protection of particular risks.
