Nitrogen

Approx.
Oxygen 10-12%
Oxygen

Nitrogen

Agent: clean
Extinguishing principle: displacement of Oxygen
Extinguishing concentration: min 30%
< 14.5% O2
Storage stage: as expended gas
Effect on people: harmless
(due to not having medical
effect on blood supply)

3. 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

4. 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

5. SINORIX CDT 300 bar regulated
   
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.

6. 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)

7. 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, ….)

18. Benefits of the SINORIX CDT regulated nitrogen system
SINORIX CDT 300 bar regulated
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.

19. 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

20. SINORIX CDT 300 bar regulated
Examples of applications of the CDT system:
Computer room
Anechoic chamber
Electrical rooms
Solvent storage
Cold rooms
Deep-seated fires
etc…

21. SINORIX CDT International Approvals
Nitrogen is recognised by the following organisations:
Authorities and Laboratories:
VdS, LPC, FM, UL, CNPP, HK-FSD, etc
Agreement by the French Ministry of Health to the use of nitrogen
as an extinguishing agent in the presence of people
Standards:
CEA 4007&4008/NFPA 2001/UL 2127/ISO & CEN 14520
Siemens introduced nitrogen
as an extinguishing agent on the international stage for 4 years

22. SINORIX CDT - Approvals
The IEAG APSAD Gas Committee issued a favourable opinion on Nitrogen 300 bar systems since December 2004
More than bottles installed since 02/2005
VdS approved S-number + G-numbers

23. SINORIX CDT 300 bar regulated
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
