Inert Gas based Suppression systems are made up of gases found in the atmosphere and are therefore completely environmentally friendly. IG-55: ‘Argon (IG-01), 50% Argon and 50% Nitrogen’ & IG-541: Nitrogen (IG-100) and 52% Nitrogen + 40% Argon + 8% CO₂ are the composition of the two Gases. They work by completely flooding the room, reducing the oxygen content necessary for combustion, but at the same time ensuring adequate oxygen concentrations for use in occupied areas.
They can work at pressures around 200 bar (2900psi), up to 300 bar (4350psi) depending on the volume/ concentration needs, providing savings in the installation cost. Thanks to the use of calibrated restrictors which reduce the pressure, conventional schedule pipes can be used. This system is specifically designed for installations with longer distance pipe runs.
