INERGEN® is a mixture of 52% Nitrogen, 40% Argon and 8% CO2.  However, in the event of a fire, when INERGEN® is discharged, it mixes with the air present in the room to create a mixture that comprises of 67.3% Nitrogen, 12.5% Oxygen, 17% Argon and 3.2% Carbon Dioxide.

This discharge mixture makes INERGEN® singularly unique. No other inert gas has the unique ability to rapidly extinguish a fire yet at the same time provide a safe environment for any person within the occupied area by actually decreasing cardiac distress and maintaining arterial blood oxygenation and mental performance in low oxygen levels. 

Equally important, unlike some chemical gaseous fire suppression agents, INERGEN® does not, and could never create a reaction with a fire to create extremely harmful toxic or corrosive by-products. 

INERGEN has been extensively used throughout the world as a preferred gaseous fire suppression agent for over 16 years and remains the longest surviving Halon replacement on the market to date.

Cost studies have shown that INERGEN is cost competitive when compared with the most popular chemical agents on typical systems. INERGEN does not take up premium floor space as the cylinders can be placed remotely from the protected risk. 

What types of INERGEN® system are available?

There are three types of INERGEN® system available, subject to the type of fire risk involved.

Inergen Premier System

INERGEN® Premier Gaseous Fire Suppression Systems

INERGEN® Premier is a 300 bar inert gaseous fire suppression system ideally suited for large “Multiple Area Protection.” It is controlled by a BS 7273 analogue/addressable fire detection and alarm system specifically designed and dedicated for gas release. more

INERGEN® Conventional Gaseous Fire Suppression Systems

INERGEN® Conventional 300 bar inert gaseous fire suppression systems are ideally suited for medium sized “Business Critical Areas” of protection.” It is controlled by a Conventional fire detection and alarm system specifically designed and dedicated for gas release. more
