Inert gas extinguishing systems utilize gases like argon or nitrogen to
reduce oxygen levels, effectively suppressing fires without leaving residue,
making them ideal for protecting sensitive equipment. Argon and nitrogen,
being natural components of ambient air, are non-toxic and non-conductive, ensuring safety in occupied areas.

Key advantages of inert gas extinguishing systems include:

  • Exceptional effectiveness, even in high-risk or concealed hazard zones.
  • Non-conductive and residue-free, suitable for protecting valuable equipment.
  • Non-toxic at required concentrations, making them safe for occupied areas.
  • Environmentally friendly, with no harmful impact on the atmosphere.
  • Widely available, allowing for quick and cost-effective reactivation.
  • Cost-effective multi-zone systems for various extinguishing needs.
  • High flexibility for modifications, facilitated by the Oxeo storage system.
  • Oxeo technology enables more compact storage, requiring less space.
  • Constant Flow technology ensures a consistent flow during a fire, allowing for smaller pressure relief flaps.
  • The MX Design Manager calculates optimal system solutions for each project, ensuring efficiency and effectiveness.

Ex­tin­guish­ing gas stor­age

The ex­tin­guish­ing agent is stored in high-pres­sure gas cyl­in­ders, which are then used in com­bin­a­tion, en­abling both the
op­tim­iz­a­tion of avail­able space and ex­tend­ib­il­ity of the Oxeo stor­age sys­tem. The filling pres­sure of every single cyl­in­der is
con­stantly mon­itored for leak­age with pres­sure gauges and the res­ults are dis­played. Any error mes­sages are trans­mit­ted to the fire de­tec­tion and ex­tin­guish­ing con­trol panel. This means that the quant­ity of avail­able gas is con­stantly con­trolled. The quant­ity of ex­tin­guish­ing gas to be stocked de­pends on the fire haz­ard and the size and nature of the pro­tec­ted fa­cil­ity. The mod­u­lar
struc­ture of the Oxeo stor­age sys­tem al­lows for per­fect ad­apt­a­tion to the cus­tomer’s in­di­vidual needs and local con­di­tions and of­fers max­imum flex­ib­il­ity, es­pe­cially for sys­tem modi­fic­a­tion or ex­ten­sion.

How does an inert gas ex­tin­guish­ing sys­tem work?

Oxeo Con­stant ­Flow tech­no­logy op­er­ates with high-per­form­ance pres­sure reg­u­lat­ors moun­ted dir­ectly on the ex­tin­guish­ing agent cyl­in­der valves. At the start of the ex­tin­guish­ing pro­ced­ure the op­er­at­ing pres­sure is thus already re­duced to a max­imum of 60 bar at the out­put of the ex­tin­guish­ing agent cyl­in­ders. In ad­di­tion, a con­stant stream of ex­tin­guish­ing agent is cre­ated without a pres­sure spike. In con­ven­tional inert gas ex­tin­guish­ing sys­tems on the other hand the gas es­capes from the cyl­in­ders into the pipe net­work at the be­gin­ning of the ex­tin­guish­ing pro­cess with a char­ging pres­sure of up to 300 bar.

This cre­ates a pres­sure spike at the be­gin­ning of an ex­tin­guish­ing pro­cess as well as a heavy stream of ex­tin­guish­ing agent which rap­idly de­creases with the dur­a­tion of the flood­ing .                                                                                                                             A cru­cial ad­vant­age :  In Oxeo ex­tin­guish­ing sys­tems with Con­stant­ Flow , thanks to the con­stant stream of ex­tin­guish­ing agent, pres­sure re­lief flaps can turn out to be 70 % smal­ler than in con­ven­tional inert gas ex­tin­guish­ing sys­tems. The ex­tin­guish­ing areas can be planned more flex­ibly.

Smal­ler pres­sure re­lief flaps can be more eas­ily in­teg­rated into ex­ter­i­ors and the area ex­cess pres­sure from base­ments can be con­duc­ted via small chan­nels into the open air without any prob­lem. To­gether with the spe­cial nozzles with SPA si­len­cers the con­stant stream of ex­tin­guish­ing agent without a pres­sure spike al­lows a “soft flood” in the event of fire.

The gentler flood­ing pro­cess re­duces vi­bra­tions on the pro­tec­ted equip­ment and in par­tic­u­lar is gentle on par­tic­u­larly sens­it­ive equip­ment such as ro­tat­ing hard drives in server rooms and data cen­ters. When using Oxeo Con­stant­ Flow tech­no­logy the       con­nec­ted con­duits and se­lector valves need only to be de­signed for the low pres­sure level of 60 bar max­imum, which may    res­ult in sig­ni­fic­antly prof­it­able solu­tions being im­ple­men­ted in many cases.

 

Ap­plic­a­tions

As inert gases are elec­tric­ally non-con­duct­ive and leave no ex­tin­guishant residues be­hind in the event of fire, This ex­tin­guish­ing sys­tems are an out­stand­ing solu­tion to pro­tect valu­able goods and ir­re­place­able cul­tural ob­jects or pre­vent elec­trical or         elec­tronic equip­ment from being out of op­er­a­tion for a long time.

Inert Gas ex­tin­guish­ing sys­tems are also best suited for the pro­tec­tion of spe­cial risk areas with flam­mable li­quids and other haz­ard­ous sub­stances, such as paint fa­cil­it­ies, and of areas with con­cealed fire sources such as auto­mated stor­age and re­trieval sys­tems. With argon even metal fires can be ex­tin­guished.
