CO2

CO2 is normally colourless, odourless and during distribution takes on the appearance of white vapour; it is non corrosive; it does not damage materials in any way and it does not wet.

Carbon dioxide, as opposed to air, does not contain a sufficient quantity of oxygen to feed combustion; it vaporises rapidly without residue of any kind, causing a strong drop in temperature, a factor which increases the extinguishing effect of CO2 remarkably.

Humans cannot breathe in a setting saturated with CO2 and the due precautions should therefore be taken before entering a room where this gas has been distributed in large quantities.

The fire-fighting system uses carbon dioxide in its liquid state as its extinguishing agent, stored in cylinders at a pressure of approximately 55 bar and at 15°C.

The operating method is completely automatic thanks to the detection which causes the extinguishing agent to be discharged thanks to the electrical command and control panel and the special commands and automatic valves. In addition to the automatic operation, the system also features a mechanical manual actuation device. The sizing of the system and the quantities of CO2 are suitably calculated, guaranteeing extinguishing in accordance with NFPA 12.

CO2 systems are available both as total flooding and “local application” for the dedicated protection against particular risks.
