INERGEN Gaseous Fire Suppression System

The INERGEN Gas Suppression System is a clean agent, non-toxic, non-corrosive, inert gas fire suppressant agent consisting of natural gases that extinguish a fire without causing harm to the people, assets or the environment.

INERGEN® IG-541 Gas Fire Suppression System is particularly well suited to suppressing fires in special hazards where an electrically non-conductive medium is essential or desirable, where clean-up of other agents presents a problem, or where the risk is usually occupied and requires a non-toxic agent.

When discharged into an area or room, a correctly designed clean agent INERGEN Fire Suppression System lowers the oxygen concentration below that supported by combustion.

Environmental Credentials

INERGEN (IG-541) was introduced as an alternative to earlier gaseous fire suppression agents and is a compound of 3 naturally occurring inert gases that comprise our atmosphere. Argon (40%), Nitrogen (52%) and Carbon Dioxide (8%). These three gases do not support combustion (combined or separately). 

INERGEN has zero Ozone Depleting Potential (ODP), zero Global Warming Potential (GWP) and doesn’t contribute unique chemical compounds with extended atmospheric lifetimes as other Gaseous Fire Suppression Agents can.

Improvements of INERGEN

The addition of Carbon Dioxide in INERGEN agent increases the respiration rate, which allows the body to accept more oxygen from the depleted oxygen environment created by a discharge of a suppression system. INERGEN’s ability to increase breathing rates is arguably an improvement upon older Gaseous Fire Suppression Agents, such as IG-55 & IG-100 (when all other factors are equal).

Applications for INERGEN IG-541

The following lists special hazard applications that INERGEN IG-541 Gas Suppression systems are well suited to protect:

  • Computer Rooms
  • Subfloors
  • Data Centers
  • Telecommunications
  • Normally occupied or unoccupied electronic area where equipment is either extremely sensitive or valuable.
  • Museums
  • Libraries
  • Archives
  • Machinery Spaces
  • Switchgear

INERGEN Exchange Cylinder Service

FSP offers Exchange INERGEN Cylinders to allow facilities to quickly return to operational status of a Fire Suppression System after a discharge. We can deliver the INERGEN Exchange Cylinders directly to the site and facilitate removal of the empty INERGEN cylinders and installation of the new, or work with your team as required. “Flexibility of Service” is one of our defining principles.

INERGEN Cylinder Refill Service

FSP offers INERGEN Refill services to the industry at great rates.

Inergen Cylinder Sizes

Inergen Cylinders come in several Pressures. The most common is 200 bar INERGEN and 300 bar (iFLOW) INERGEN Cylinders, but we also sell INERGEN 150 bar cylinders, systems and services.
