CARBON DIOXIDE GAS

Under normal atmospheric temperature and pressures, carbon dioxide exists as a colorless,
odorless gas which is about 1.5 times heavier than air. Carbon dioxide will not burn or support

combustion and will not sustain life. When conned within a suitable pressure vessel and
depending on temperature and pressure conditions, carbon dioxide can exist in any of three
stages of matter; solid, liquid and gas.

HIGH PRESSURE CARBON DIOXIDE SYSTEM

High pressure CO2 system is a specialized re extinguishing system designed to maintain the
carbon dioxide supply at 21º C and 850 psig in strength alloy steel cylinders. The cylinders
contain the CO2 required to protect the largest single hazard. On large hazards where several
cylinders are required, a manifold is used to connect each cylinder by means of exible hoses

and check valves. Cylinder valves control the CO2 ow to the hazard through properly sized
pipe, terminating in nozzles that apply the CO2. Flow rate is controlled by nozzle orices as well
as pipe sizes. The cylinder master valves are electronically operated and the slave valves are
pressure actuated. The master valves can be automatically and/or manually operated.

CO2 EXTINGUISHING SYSTEM MOST IDEAL

FOR PROTECTING:

Ø Paint and varnish manufacturing and processing areas.

Ø Powder coating and Painting boots.
Ø Transformers and substations.

Ø Rolling mills and Turbines.

Ø False Floors and cable shafts.

Ø Engine test benches and SHIP Engine Room / compartments.

Ø Printing machines.
