Why choose an Inergen system?

When it comes to fire suppression, particularly in environments with valuable equipment or sensitive data, choosing the right system is crucial. Among the various options available, Inergen stands out as a leading choice for many professionals. Inergen, a product of Fire Eater, is an advanced inert gas fire suppression system renowned for its unique properties and numerous advantages over other inert gas systems.

What is Inergen?

Inergen is a blend of three naturally occurring gases: Nitrogen (52%), Argon (40%), and Carbon Dioxide (8%). This combination is designed to suppress fires efficiently while being safe for both people and the environment. Inergen extinguishes fires by reducing the oxygen concentration in the protected area to a level that is too low to support combustion but still safe for human occupancy.

Key Features of Inergen

  1. Human Safety – One of the most significant advantages of Inergen is its safety for human occupancy. While most inert gas systems lower oxygen levels to suppress a fire, Inergen includes a small percentage of carbon dioxide, which stimulates the human body to increase its respiration rate. This compensates for the reduced oxygen levels, ensuring that individuals can still breathe comfortably and evacuate safely in an emergency.
  2. Environmentally Friendly – Inergen is composed entirely of naturally occurring gases, which means it has zero ozone depletion potential (ODP) and a global warming potential (GWP) of zero. This makes it an environmentally responsible choice for fire suppression, aligning with green building practices and sustainability goals.
  3. No Residue and Non-Corrosive – After discharge, Inergen leaves no residue and does not cause any damage to sensitive equipment or electronics. Unlike water-based suppression systems, Inergen ensures that critical operations can resume quickly after an incident, with minimal clean-up required.


Approvals and Certifications

Inergen’s effectiveness and safety have been validated through rigorous testing and certifications. It has received approvals from various international regulatory bodies, underscoring its reliability and performance:

– UL (Underwriters Laboratories)**: Inergen systems are UL listed, which signifies that they meet stringent safety and performance standards.

– FM (Factory Mutual)**: FM approval ensures that Inergen systems are suitable for use in high-value environments and have been tested for effectiveness and reliability.

– ISO 14520**: Inergen complies with the ISO 14520 standard for gaseous fire-extinguishing systems, which specifies requirements and test methods for gaseous systems.

-DNV GL (Det Norske Veritas Germanischer Lloyd): Inergen is DNV approved, meeting the stringent standards for safety and performance set by this international classification society. This approval is particularly important for maritime and offshore applications, where compliance with DNV GL standards is mandatory.

Advantages Over Other Inert Gases

Enhanced Safety Features

While other inert gas systems also lower oxygen levels to suppress fires, not all include the added benefit of carbon dioxide. This makes Inergen unique in providing a safer environment for human occupants during a fire event. For example, systems that use only nitrogen or argon do not offer the same level of respiratory stimulation, potentially posing a higher risk to individuals trapped in the area.

Effective Fire Suppression

Inergen’s specific gas mixture is optimized for rapid fire suppression. It quickly displaces oxygen to a level that cannot sustain combustion, effectively extinguishing fires in seconds. This rapid response minimizes fire damage and reduces downtime.

Versatility and Adaptability

Inergen systems are designed to protect a wide range of environments, including data centres, server rooms, cold storage facilities, museums and archives. Its versatility makes it a preferred choice for facilities where both fire protection and the safety of occupants and assets are paramount.


Inergen by Fire Eater is a superior inert gas fire suppression system that offers unmatched safety, environmental benefits, and effectiveness. Its unique blend of nitrogen, argon, and carbon dioxide sets it apart from other inert gases, ensuring optimal fire suppression while maintaining a safe environment for occupants. With its numerous certifications and approvals, Inergen is a reliable and trusted choice for protecting valuable assets and critical infrastructure.

Investing in an Inergen system means choosing a solution that prioritizes safety, sustainability, and performance—qualities that are indispensable in today’s demanding and ever-evolving landscape.
