CO2 and the environmentThe emission of CO2 is increasingly
being discussed in connection with
global warming. The CO2 for fire
extinguishing systems is not specially
manufactured, but is taken from by-
products of technical processes or from
natural resources. Furthermore, CO2
extinguishing systems prevent the
formation of CO2 and other environ-
mentally harmful materials from fires.
There is therefore no need to forbid
the use of CO2 for economical reasons.
On the contrary, fire extinguishing with
CO2 systems plays a major role in
environmental protection.

CO2 high pressure systems
The extinguishing medium is stored as
liquid in steel cylinders (approx. 60 bar).
The following cylinder sizes are
available:
8 l / max. 6 kg CO2 - filling
10 l / max. 8 kg CO2 - filling
40 l / max. 30 kg CO2 - filling
67 l / max. 50 kg CO2 - filling
According to the required quantity of
extinguishing medium cylinder
batteries (of uniform bottle size) are
combined.
Each cylinder is supervised by a scale
for CO2 loss. The response of a scale can
be signalled remotely at the fire
detection panel via a light barrier.
When fire is identified by the auto-
matic detector (1) or the actuation of
the manual push button (2) the fire
detection panel (3) will electrically
open the alarm and control bottles.
The discharged CO2 activates a pneu-
matic delay device (6) and sounds a
mechanical horn (7) in the protected
room.

CO2 low pressure systems
Sketch of the CO2 low pressure system
For cost reasons quantities of extin-
guishing medium from approximately
2 t and above are not stored in single
bottles but in a container. The CO2 is
cooled down to –20°C in an insulated
tank and is liquid at this temperature
at a pressure of approximately 20 bar.
The complete tank (8) stands on a scale
which responds on a CO2 loss of
approximately 10% by weight. The
transfer of this signal of a CO2 loss to a
fire detection panel (3) is possible via a
limit switch. On a fire signal from the
automatic (1) or the manual (2)
detectors the fire detection panel
actuates a solenoid valve via the time
delay device (6) and the pneumatic
siren (7) is actuated together with the
electric alarm devices (4, 5). At the
same time the pre-warning time starts
to run in a pneumatic and in an electric
timer. After the elapse of the pre-
warning time in both devices the
section valve (9) is opened pneumati-
cally and the fire area is flooded. Prior
to the start of the flooding doors and
other openings are closed electrically
or pneumatically, but not locked. After
the elapse of the flooding time, which
is normally 120 seconds, the section
valve is closed.

All described control functions are
related to the extinguishing area in
which the fire has been detected. For
this reason, a malfunction in another
extinguishing area is impossible
without a simultaneous alarm and the
running of a delay time.
