Types of clean agents

NFPA 2001 provides crucial guidance on the two main categories of gaseous clean agent systems widely used in fire suppression. These systems are essential for protecting mission-critical applications from the devastating consequences of fires. Inert gases, such as IG-541, work by depleting oxygen to extinguish fires, while halo-carbon-based agents, such as HFC 227ea, interrupt the molecular reaction of fires by disrupting the fire tetrahedron.

When comparing these two types of systems, it is essential to consider various factors such as cost to refill, shelf life, and environmental impact. Halo-carbon-based systems offer several benefits over inert gas systems. First, they require lighter suppression agent cylinders, which occupy less storage space. This is a critical consideration during design, especially in structures where weight is a concern. Additionally, fewer halo-carbon cylinders are required to protect the same volume, making them an ideal choice for buildings with limited storage space.

Furthermore, halo-carbon-based systems have lower cylinder pressures than inert gas systems, reducing the likelihood of piping and fitting failures during release. This means there is less risk of a system malfunction that could potentially exacerbate a fire. Also, the pressure relief venting of the protected enclosure is typically less common with halo-carbon systems.

When selecting a clean gaseous agent system, it is crucial to consider each facility's unique needs and requirements. The team must weigh the pros and cons of each system type and choose the one that best meets their needs. With NFPA 2001 as a guide, facilities can make an informed decision that will help them protect their mission-critical assets from fire damage.

Construction requirements

Protecting your business and employees from the potential harm of a fire is a top priority, and choosing the right fire suppression system is a critical component in achieving this goal. While inert gases can reduce oxygen levels to a safe level for humans and prevent fire, halo-carbon-based agents are designed to extinguish fires while heat, fuel, and oxygen are present. In addition, the National Fire Protection Association (NFPA) and other standards require that clean gaseous agents are maintained at a minimum concentration threshold for a specific duration known as the "hold time."

The hold time is critical in allowing the clean gaseous agent to extinguish the fire and effectively reduce the possibility of re-ignition. To ensure that the hold time is achieved, it is essential to maintain room integrity, which refers to sealing the room to prevent the clean gaseous agents from leaking out. This involves filling holes and leakage paths in walls and ensuring that divisions in the protected area are continuous to the roof or floor/ceiling assembly above. Dampers or HVAC equipment controlled by the fire alarm system may also be required to maintain room integrity. Finally, seals around doors with automatic closers may also be necessary to minimize leakage.

Measuring room integrity during construction is done through a "door fan test," which uses specialized equipment to pressurize the enclosure and measure leakage rates. This test ensures that your fire suppression system works effectively and that your business and employees are safe from harm. Ensuring your business's and employees' safety should be a top priority. A clean gaseous agent fire suppression system with adequate room integrity can go a long way in achieving this goal.

Detection systems

Adequate fire suppression systems require early detection and rapid response to prevent the spread of fire. Clean agent systems are especially effective in containing fires at the incipient stage, so using smoke-sensing detectors to identify combustion products early on is crucial. Conversely, delayed detection through heat-sensing detectors can result in more extensive fires, especially with halo-carbon-based agents that can release hazardous byproducts through thermal decomposition.

Choosing the right control panel is another critical aspect of fire suppression systems. The panel must be listed for fire suppression agent release and cross-listed with the solenoid that releases the clean gaseous agent into the piping network. This requirement, mandated by NFPA 2001, ensures seamless communication between the control panel and the clean agent system.

Unlike other fire protection systems that involve a single trade, clean agent systems require the coordination of multiple businesses, including detection/controls, piping, mechanical shutdowns, and room integrity. Therefore, a robust specification ensures seamless coordination among these trades. Third-party system testing is also recommended to ensure its reliability and effectiveness. Considering these considerations, you can choose the right clean agent system that meets your fire suppression needs and keeps your property and people safe.

Clean Agent Fire Suppression Gas Refill and Recharge


If you're running a building or facility with a Clean Agent fire suppression system, you understand how critical it is to recharge the system after each use or discharge. The system responds quickly to any electrical fire, preventing significant damage to your valuable assets like data centres, archives storage, and computer rooms.

A fully functioning Clean Agent system reacts promptly and diffuses the fire before it can spread and cause further damage. However, once the system has been triggered, it needs to be recharged to be ready to handle the next fire emergency.

Without refilling the Clean Agent gas, your system will not be as prepared to put out the subsequent fire. Therefore, even a small fire could lead to substantial property loss or damage if it cannot be contained quickly.

It's crucial to prioritize the recharge of your Clean Agent system to ensure the safety of your personnel, assets, and business operations. Recharging the system will restore its ability to react and extinguish fires, reducing the risk of further damage to your building or facility.

Our company offers expert Clean Agent fire suppression system maintenance, including timely refilling of your system. We understand the importance of protecting your business from the devastating effects of fire damage, and we're committed to helping you achieve this goal.

Inergen, Argonite, IG55, NOVEC 1230, FM200, and SR200 are some of the most advanced fire suppression systems available. These systems utilize different chemicals and gases to extinguish fires, each with unique features.

Inergen is a fire suppression system that employs a mixture of nitrogen, carbon dioxide, and an inert gas such as helium, neon, argon, krypton, or xenon. It is widely used in data centres, telecom facilities, and other sensitive areas because it is non-toxic and non-conductive. Inergen reduces the oxygen concentration in the air, effectively extinguishing the fire without leaving any residue.

Argonite and IG55 are other popular fire suppression systems that use a mixture of nitrogen and argon. These systems are environmentally friendly, as they are naturally present in the atmosphere and do not contribute to ozone layer depletion or greenhouse effects. As a result, they are instrumental in areas where water damage needs to be avoided, such as server rooms and museums.

NOVEC 1230 is another advanced fire suppression system that uses a proprietary chemical called dodecafluoro-2-methyl pentane-3-one. This compound is non-toxic, non-corrosive, and has zero ozone depletion potential. NOVEC 1230 works by reducing the heat energy of the fire, effectively extinguishing it without leaving any residue.

FM200 and SR200 are other popular fire suppression systems that use heptafluoropropane, a colourless and odourless gas widely used in gaseous fire suppression systems. These systems work by absorbing heat energy from the fire and reducing the oxygen concentration in the air, effectively extinguishing the fire without leaving any residue.

In conclusion, the choice of fire suppression system will depend on the nature of the environment in which it is to be deployed. Inergen, Argonite, IG55, NOVEC 1230, FM200, and SR200 are all highly effective and reliable systems that can provide optimal protection against fire damage.
