SINORIXTM CDT


Characteristic of nitrogen (N2)

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)

Inert Gas ExtinguishingInert 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


• 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

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.



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)


• 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

• Excellent performance on deep-seated fires with a retention time of 20 minutes

- suitable for archives

• Using inert gas

- no residues after a discharge

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


Examples of applications of the CDT system:

• Computer room

• Anechoic chamber

• Electrical rooms

• Solvent storage

• Cold rooms

• Deep-seated fires

• etc…



SINORIX CDT International Approvals

Nitrogen is recognised by the following organisations:

- Authorities and Laboratories:VdS, LPC, FM, UL, CNPP, HK-FSD, etcAgreement 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


SINORIX CDT - Approvals

The IEAG APSAD Gas Committee issued a favourable opinion on Nitrogen 300 bar systems since December 2004

More than 10000 bottles installed since 02/2005

VdS approved S-number + G-numbers


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
