Inert gas is most often used to extinguish server rooms, data rooms, archive rooms, laboratories, etc.

The biggest disadvantage of inert gas extinguishing systems was no stable output pressure and no constant flow rate until the last nozzle.
With the latest generation inert gas extinguishing systems, this disadvantage of the first generation systems disappeared. A new valve was developed that provided a stable output pressure with a constant flow rate.

Extinguishing with inert gas is safe and does not damage our environment. The gases used are nitrogen and argon and are obtained from the air.  To extinguish, the air composition in the room is changed by using gases that already exist in the air.  The oxygen content in the air is reduced without endangering people and visibility is maintained because the temperature only drops slightly, so no fog forms.

To extinguish certain fires, the use of CO2 as an extinguishing gas is still preferable.

Carbon dioxide, commonly called carbonic acid or CO2, is gaseous under atmospheric conditions.  CO2 gas is colorless, odorless and electrically non-conductive.

Fires involving a large number of materials and in all kinds of installations can be effectively controlled and/or extinguished using water.  Water is certainly the most commonly used extinguishing agent.

By spreading that water, divided into a large number of fine droplets, over the seat of the fire, the options for extinguishing it are enormously expanded.

In today's kitchen appliances, flammable fats and oils come into contact with high-power heat sources.  There is usually also a strong air exchange available that can provide a supply of oxygen and thus all elements of the fire triangle (flammable substance - oxygen - ignition source) are present. WHDR extinguishing is the ideal solution for kitchen installations.

Heptafluoropropane - HFC227ea (called in the standards and regulations  – by manufacturer Dupont de Nemours FM-200®) and Pentafluoroethane (called by manufacturer Dupont de Nemours FE-25™ and by Fike Corporation: Ecaro25™) are extinguishing agents with chemical composition.  The products are also used for other purposes. This extinguisher is no longer installed, but we still maintain it.
