EXTINGUISHING SYSTEMS

»»Ò³
As digitalization increases, concen-
trations of value continue to grow
larger, and ever more expensive
and powerful hardware is needed
to meet the requirements for tele-
communications, service providing
and network management. The
risks are growing: loss of data or
business interruption would have
disastrous consequences for any
operator. And the damage that a
fire can cause is horrific: whole
rooms of technical equipment and
software are destroyed by fire and
extinguishing agents, not to men-
tion the dangers for people and
the environment. This is why relia-
ble and clean fire protection solu-
tions are the only way to prevent
loss of image and market shares.
With its INERGEN
®inert gas,
TOTAL WALTHER offers the ideal
fire protection solution on a global
basis. INERGEN
®extinguishing
systems are the only ones to give a
100% guarantee that a fire will be
put out with no residues at all, with
no risk whatsoever to any people
present.
The name INERGEN
®refers to the
individual components of the extin-
guishing agent, which is a mixture
of INERt gases and nitroGEN.
An extinguishing agent that you
can breathe
During the extinguishing process,
the low CO2concentration that is
harmless to the human organism
stimulates an involuntary deepe-
ning of the breathing, ensuring
that the organism is supplied with
adequate oxygen. This "automa-
tic" stimulation of deep breathing
also occurs in people who are
unconscious or asleep.
As well as protecting people and
property, modern extinguishing
concepts must offer maximum com-
patibility with the environment if
they are to be feasible.
Excellent environmental protection
Unlike synthetic extinguishing gas-
es, all the components of INER-
GEN
®are actually taken from the
air –in other words, their origins
are purely natural. Once the fire
has been extinguished, they return
unchanged to the atmosphere with-
out polluting the environment. This
is how INERGEN
®extinguishes
without leaving any residues, with
100% neutrality towards the en-
vironment.
INERGEN
®: THE CLEAN SOLUTION.
INERGEN
®
extin-
guishes without
leaving any resi-
dues, with 100%
environmental
neutrality –to
avoid harming
nature.
INERGEN
®
consists of 40% argon, 52%
nitrogen and 8% carbon dioxide –all
natural constituents of the air.

INERGEN
®is ideal for every type
of room where there are people as
well as valuable items of property.
INERGEN
®is a very dry gas mix-
ture, so it has low conductivity. This
aspect is especially important for
applications in transformer and
high-voltage rooms where non-insu-
lated components are installed.
During the extinguishing process,
INERGEN
®systems reduce the air
humidity, minimizing the probabil-
ity of sparkovers which could
cause a further fire risk.
INERGEN
®'s inert behaviour also
makes it ideal for use as an extin-
guishing agent in chemical process
engineering. Archives and museums
benefit from the long holding times
for the extinguishing concentra-
tions, and the extremely small tem-
perature drop when an INERGEN
®
flooding is carried out. Fires involv-
ing valuable documents or paint-
ings can be reliably avoided.

NO ACCIDENTAL TRIGGERING!
Thanks to ultra-modern technology,
an INERGEN
®extinguishing sys-
tem operates in the simplest poss-
ible way. As soon as the automatic
fire detectors have registered a
developing fire, the control panel
triggers the acoustic warning sig-
nals (as well as visual signals, if fitt-
ed). After the pre-warning time has
elapsed, the fast-opening valve on
the pilot cylinder is activated by a
triggering pulse.
A revolution in extinguishing
control
TOTAL WALTHER is setting new
standards in personal protection
with the electro-mechanical Impuls
2000 system, which we have de-
veloped and patented ourselves.
Impuls 2000 is a reliable, cost-
effective innovation that makes it
impossible for a gas extinguishing
system to be affected by spurious
electronic pulses –due to high volt-
age, for example. Unambiguous-
ly defined pulses are required to
trigger a brief, electro-mechanic-
ally controlled pre-warning time so
that the extinguishing area can be
evacuated; once this has been
ensured, the extinguishing agent
can be deployed as soon as
possible.
Safety during the extinguishing
process
The pressure reducing unit brings
the cylinder pressure down from
200 to 60 bar. INERGEN
®then
flows through the extinguishing
nozzles into the extinguishing sec-
tion. As of the reduced pressure,
the extinguishing agent is discharged
more gently, eliminating any addi-
tional danger to valuable prop-
erty. In multi-section systems, the
electro-pneumatic control logic
(EPSL) reliably ensures that the
right amount of extinguishing
agent is assigned to the right sec-
tion.
An INERGEN
®extinguishing sys-
tem can also be activated with a
manual alarm button.

GOOD REASONS FOR CHOOSINGINERGEN
®
Unlike comparable synthetic extin-
guishing agents,INERGEN
®has
several unbeatable advantages for
people, property and the environ-
ment.
Harmless to the environment
INERGEN
®does not disturb the
ecological equilibrium, because it
is a mixture of gases made up of
natural constituents.
Harmless to people
People can leave the fire area well
before the flooding. Even so,
INERGEN
®has the effect of stimu-
lating breathing: this ensures that
any injured or unconscious people
left behind in the room are protect-
ed from a shortage of oxygen.
Optimal protection for property
In rooms with very valuable tech-
nical equipment, INERGEN
®extin-
guishes the fire without leaving
any residues at all. What is more,
there is only a minimal tempera-
ture drop as the gas enters the
extinguishing section, so no conden-
sate is formed.
Worldwide approval
INERGEN
®is approved without
restrictions as a natural extinguish-
ing agent.
No shortage of resources
The natural ingredients are always
available. INERGEN
®is simple to
manufacture, unlike comparable
synthetic extinguishing agents.
Safety check with no risks
Test floodings to check whether an
INERGEN
®system is in good work-
ing order are allowed at any time,
without polluting the environment.
No decomposition products
Unlike chemical extinguishing
gases, INERGEN
®does not form
any highly toxic decomposition
products at high temperatures.
Clear visibility in an emergency
There is no fogging of the room
when the extinguishing agent is
discharged from the nozzles,
because INERGEN
®is stored in
gaseous form –so visibility is unim-
paired, and (for example) escape
routes are easy to see.
Constant extinguishing effect
INERGEN
®is only slightly heavier
than air, so the holding time for the
extinguishing concentration is long-
er than for heavy gases.
Every extinguishing operation is
successful
INERGEN
®has proven its merits in
applications all over the world.
This is why it is recognized by the
VdS and other national and inter-
national institutions. Leading insur-
ers grant premium discounts.

A fire develops quickly –INERGEN
®
extinguishing systems offer reliable
protection for people and property
.
A technical detail that has a tremendous
effect: optimal protection for people
thanks to "Impuls 2000".

»»Ò³
INERGEN
®is not only friendly to
the environment and harmless to
people: the 200 bar storage tech-
nology also offers several other
advantages that are sure to pay
off.
Simplified installation
The connection method (patent
applied for) eliminates the need
for welding work in the high-pres-
sure section of the system.
Installation work is also reduced
because the components are link-
ed on a modular basis.
Compact manifold technology
Three rows of cylinders can be
connected to one manifold at the
same time.
Quick replacement
Thanks to the patented cylinder fix-
ture, cylinders can be removed or
fitted quickly (e.g. after the system
has been operated).
Time-saving inspection
A simple pressure measurement is
sufficient to check the contents of a
high-pressure cylinder.
