Inert Gas Extinguishing
Inert gas systems aim to drop the O2 to between 10% and
14%. Ideally inert gas systems aim for ca. 12.5% O2

SINORIX CDT 300 bar regulated
• Nitrogen: Main component of air, inert and odourless
• Extinguishing agent which works by reducing the oxygen level
(< 14%)
• Ecologically clean
ODP = 0 (Ozone Depletion Potential)
GWP = 0 (Global Warming Potential)
• Does not create breakdown products in contact with a
naked flame
•Siemens was the first to have the idea of using nitrogen as an
extinguishing agent

• 60 second discharge with extinguishing before the end of
the discharge.
• Pipework pressure < 100 bar
• Centralised system with optional directional
valves
• Modular system for protection of small enclosures
• Using 40.3% of nitrogen reduces oxygen level to 12.5%,
which equates to air breathed at an altitude of 3,500 m.

Sinorix CDT: The best solution compared with gas blends
Unlimited access to natural gases
Not dependent on specialist suppliers
- Natural gas blends are available from only a limited number of
suppliers
No extra costs for an inert gas without extinguishing benefits
- No patent costs for N2, Ar and CO2
- The price of a gas blend is about 5 times that of a single gas
No CO2 in SINORIX CDT
(Unlike IG-541, which contain CO2)

SINORIX CDT 300 bar regulated – Key points
• Excellent extinguishing performance for Class A, B and C fires
- best solutions for rapidly spreading fires
- excellent performance on liquid and gas fires
• Electrically non-conductive
- safe for electronic risk
• Using inert gas
- no residues after a discharge
• Excellent performance on deep-seated fires with a retention time
of 20 minutes
- suitable for archives

What does CDT mean?
Constant
Discharge
Technology
New constant (or regulated) flow technology:
Discharge pressure is almost constant, whatever the container
pressure.
Technology developed in house by Siemens SAS and manufactured
by Production Extinction Siemens SAS.
All the accessories too (e.g.: Pressure switch, Manual actuator, ….)

Benefits of the SINORIX CDT
regulated nitrogen system
SINORIX CDT regulated nitrogen
at least one third fewer containers
compared with a 200 bar system.
More than 50% less overpressure
venting area compared with an
unregulated system.
 pressure downstream of the valve
VFR300-S less than 100 bar.

SINORIX CDT: A modular system
As well as centralised systems, SINORIX CDT also allows you the
option of modular systems
The benefits are:
• No pipework
• No nozzle orifice drilling calculation
• Installation in existing premises without disturbing the user
• Cost

All extinguishing systems using an inert agent need an
overpressure vent to avoid damage to the protected enclosure.
Even though the SINORIX CDT system uses a new constant flow
technology, reducing the venting area required by 70%, you must
still provide overpressure venting.
Siemens FR has developed its own overpressure vent
1 hour fire resistant
