Mixed Gas (IG541) Fire Extinguishing System/Fire Suppression System - Ig541
IG541 mixed gas fire extinguishing agent is a "green" environmental protection gas fire extinguishing agent which can replace halon fire extinguishing agent and has been widely used in the world. It is made of nitrogen, argon and carbon dioxide in a certain proportion of completely natural combination, no damage to the atmospheric ozone layer, do not cause greenhouse effect, with colorless, tasteless, no pollution to equipments, non-corrosive, good insulation characteristics. After the fire extinguishing agent is sprayed into the protection area, the oxygen concentration decreases while the carbon dioxide concentration in the protection area increases. A moderate increase in the carbon dioxide concentration can accelerate the respiratory rate of human beings, improve the oxygen absorption function of human beings, and maintain the need of oxygen absorption of human beings to a certain extent. IG541 extinguishing agent is stored and sprayed in gaseous form. When it is released to the high temperature protection area of fire, it will not decompose, no toxic decomposition is produced, and it will not form fog or cause blurred vision, so as to ensure that personnel can clearly see the emergency exit when escaping. It is a kind of safe environmental protection gas fire extinguishing agent, suitable for the place where people often work.| Item | QMH15/70 | QMH15/80 | QMH15/90 |
