AKRONEX CO2 Fire Extinguisher System in Pakistan: Carbon dioxide is a colourless, scentless and non-conductive gas that can effect quickly and efficiently into the protected area. Its density is about 50% higher than. the air density. During extinguishing, it is seen like a white mist. It does not make residue on the materials or affect adversely the materials. Reduces the concentration of oxygen causes suppression to fire in the space and creates a cooling effect caused by the rapid expansion of the gas. Even if the CO2 concentration is low in concentration, it should not be ignored and considered to be a danger to breathing. Also, the visibility during discharge is greatly reduced due to the formation of CO2 mist.
