IG-541 Inert Gas Fire Extinguishing System
The IG-541 inert gas mixture extinguishes fire by oxygen reduction (total flooding), has zero ODP and zero GWP, and is safe for occupied spaces such as subway electrical rooms and telecom centers.
Description
GAS-IG541-INE
Product Description
This system is available in 15 MPa and 20 MPa pressure ratings. IG-541 is a colorless, odorless, non-toxic, non-conductive, and “green” compressed gas mixture of naturally occurring nitrogen, argon, and carbon dioxide. It has an Ozone Depletion Potential (ODP) of 0 and a Global Warming Potential (GWP) of 0. It extinguishes fire by reducing oxygen concentration to below 15%, using total flooding to suppress Class A surface fires, Class B flammable liquid fires, and energized electrical equipment fires in enclosed spaces.
Primarily used for fire protection in metro electrical equipment rooms, computer rooms, data processing centers, telecommunications facilities, high-value medical facilities, museums and art galleries, libraries, archives, emergency power facilities, and cleanrooms.
