It is a facility that suppresses fire by depletion of oxygen by reducing the oxygen concentration within the protection zone to less than 15% at the time of occurrence of fire, and is a clean fire extinction facility that is harmless to human body since it leaves no residue after the release of gas.

※ Raw material: Europe, 80 L TPED approved product
Main ingredients Non-activation gas ? More than 99.9% N2
Cleaning after the releasing There is no secondary damage due to residues since it is released in gas state.
Harmless to human body Fire extinguishing agent that does not corrode equipment, etc. due to absence of generation of pyrolysis by-product (HF) and harmless to human body
Protection of life Clean fire extinction agent that does not cause suffocation even under low oxygen state of less than 15% oxygen concentration, does not generate hydrogen fluoride (HF) at the time of release and protects life
Outstanding fire extinction power It is a fire extinguishing agent with outstanding fire extinction power that suppresses fire within protection zone by being released in short period of time and prevents re-ignition of fire by maintaining fire extinction concentration for long time since it has specific gravity similar to that of air.
Environment-friendly chemical agent Environment-friendly fire extinguishing agent with global warming index (GWP) and ozone layer destruction index (ODP) of "0"

NKFS-100® characteristics

NitrexII system is developed on the basis of the program of VDS of Germany that uses the basic data of not only the stability of the supply of components such as storage container, etc. but also a diverse range of component tests (decompression valve, driven pump release, nozzle, control container pressure difference characteristics), thereby resulting in accurate release outcomes.
Reduction in storage container
It is possible to reduce maximum of 15% of the container quantity than the 20 MPa class inert fire extinguishing agent and maximum of 20% of the container quantity than the carbon dioxide container (on the basis of deep fire and electrical room)

System supply performances in accordance with the international standard
Container that acquired the system certification according to IMO848 and TPED certification according to the standards of ISO9809-2 holds a diverse range of supply performances as a product name of Nitrex.

Use of decompression valve
It suppresses the increase in pressure within the pipeline and holds safe and accurate release characteristics through the decompression function built-in the storage container valve.
Analysis of nozzle release characteristics
Optimal nozzle release characteristics were realized by measuring the oxygen concentration of the protection zone, nozzle pressure and temperature and chemical agent quantity of the storage container in real time in order to ensure that the 95% of the chemical agents of the design concentration is released within 60 seconds.

Excellence of the NKFS-100 design program
At the time of charging the fire extinguishing agent through the pipeline, it is possible to confirm the unique characteristic values of the liquid at all the nodes of the pipeline by executing ultra precision analysis of the air flow under atmospheric pressure within the pipeline and flow of chemical agent by the chemical agent pressure of the storage container at every 0.0001 second interval.
Clean nitrogen fire extinction facility that does not destroy earth environment, Nitrex II
Clean fire extinguishing agents as the chemical substances used as a means of reducing the Freon gas, the main culprit of destruction of ozone layer, are not inducing global warming. Using Nitrex II for the prevention of this side effect is the best means of preventing climate changes and global warming.
