The device of gas fire extinguishing (hereinafter «GFED») «Eol 2А050» with axial gas outflow is designed to extinguish in conditionally sealed volume fires of the following Classes:
- subclass A2 — combustion of solids not accompanied by smoldering;
- Class B – combustion of flammable liquids;
- Class C — combustion of gases;
- Class E — fires occurring in rooms with cables, electrical installations and electrical equipment under voltage up to 1000V.
The predominant area of application – protection of boards with electrical equipment, cabinets with electronic equipment for server, process control systems, power plants and substations, compartments with electrical equipment, with electric motors, pumps and other technological equipment.
Relative humidity — no more than 98% at 25°C°. Operating temperature — from -45°C up to +40°С.
Gas produced by the operation of the device does not contain ozone-depleting substances.
The quantity and composition of the main products of combustion generated during operation of the device as a percentage by volume: CO2 — 63.3%; H2O — 25.63%; N2 -10.29%; CH4 — 0.66%; H2 — 0.094%; CO — 0.001%; NH3 — 0.0006%.
