Clean Agent Fire Suppression: Protecting What Matters

Clean Agent System


Fire is a formidable force that can cause devastating damage to property, endanger lives, and disrupt business operations. To combat fires effectively, various fire suppression systems have been developed, one of which is the Clean Agent Fire Suppression System. Unlike traditional methods that employ water or foam, clean agent systems utilize specialized gases or chemicals to extinguish fires without causing harm to valuable equipment or sensitive environments. In this article, we will explore what a Clean Agent Fire Suppression System is, how it works, and its advantages.

What is a Clean Agent Fire Suppression System?

A Clean Agent Fire Suppression System is an advanced fire suppression technology designed to protect critical and sensitive environments, such as data centres, server rooms, laboratories, museums, and industrial facilities, from the destructive power of fire. It is called a “clean agent” because it leaves no residue, water, or foam behind, making it ideal for safeguarding delicate equipment and irreplaceable assets.

How Does It Work?

Clean Agent Fire Suppression Systems operate based on the principles of fire suppression by reducing the concentration of oxygen, interrupting the chemical chain reaction, or a combination of both. The key elements of a typical clean agent system include:

1. Clean Agent: Clean agents are electrically non-conductive, environmentally friendly chemicals or gases designed to suppress fires efficiently. Common clean agents include:

a. HFC-227ea (FM-200): This colourless, odourless gas quickly extinguishes fires by removing heat from the fire triangle (heat, fuel, and oxygen). It is ideal for protecting sensitive electronic equipment.

b. Novec 1230: This chemical agent is electrically non-conductive, eco-friendly, and has a low global warming potential. It extinguishes fires by cooling and removing heat while minimizing damage to property.

c. Inergen: Inergen is a mixture of inert gases, primarily nitrogen, argon, and carbon dioxide, which displaces oxygen to extinguish fires. It is safe for occupied spaces and leaves no residue.

2. Detection System: Clean agent systems are equipped with reliable fire detection mechanisms, such as smoke detectors, heat detectors, or flame detectors. When a fire is detected, the system activates.

3. Control Panel: The control panel serves as the brain of the system. It receives signals from detectors, initiates the release of the clean agent, and monitors system integrity.

4. Piping and Nozzles: A network of pipes and nozzles distributes the clean agent evenly throughout the protected area, ensuring effective coverage.

Advantages of Clean Agent Fire Suppression Systems

Clean Agent Fire Suppression Systems offer several advantages that make them an excellent choice for protecting critical assets and sensitive environments:

1. Non-Destructive: Clean agents leave no residue, water, or chemicals behind, ensuring that valuable equipment, documents, and artefacts remain unharmed.

2. Fast and Effective: Clean agents work swiftly to suppress fires, minimizing potential damage and downtime.

3. Safe for Occupied Spaces: Some clean agents, like Inergen and Novec 1230, are safe for use in areas where people are present.

4. Environmentally Friendly: Many clean agents have a low global warming potential and do not deplete the ozone layer, making them environmentally responsible choices.

5. Minimized Cleanup: Since clean agents do not leave residue, there is no need for extensive cleanup after a fire incident.


Clean Agent Fire Suppression Systems are a vital component of modern fire protection strategies, especially in environments where water or traditional fire suppressants could cause more harm than good. These systems provide rapid, effective, and non-destructive fire suppression, preserving critical assets and ensuring the safety of occupants. When it comes to safeguarding sensitive environments, clean agent systems are a reliable choice that offers peace of mind in the face of potential fire hazards.
