Clean Agents of Inert Gas Systems & HFCs
Clean Agent Fire Suppression Systems
Clean agent fire suppression systems are advanced fire protection solutions that use environmentally friendly gases to extinguish fires without causing damage to valuable assets, equipment, or the environment.
These systems are ideal for protecting sensitive environments where water or other traditional fire suppression methods would cause unacceptable damage.
Inert Gas Systems (IG-541)
IG-541 is a clean fire extinguishing agent composed of approximately 50% nitrogen, 42% argon, and 8% carbon dioxide.
Extinguishing Principle: When released in a fully enclosed protected area during a fire, this gas reduces the oxygen concentration below the level that supports combustion. However, the concentration remains sufficient for human breathing, ensuring no risk of asphyxiation.
Features of Inert Gas Systems
- Environmentally friendly with zero ozone depletion potential and zero global warming potential
- Safe for occupied spaces when properly designed
- Stored as a gas, allowing protection of areas at a considerable distance from the cylinder location
- Applicable in environments with temperatures between 0°C and 54°C
- Minimum design concentration of 37.5% and maximum design concentration of 42.8%
- Can be designed as independent network systems or combined distribution systems
HFCs Systems (HFC-227ea/FM200)
HFC-227ea (also known commercially as FM200) is a clean gaseous chemical fire extinguishing agent that primarily works through chemical flame inhibition while also having physical extinguishing properties.
This agent is colorless, odorless, has low toxicity, is non-conductive, and doesn't contaminate protected objects, making it safe for valuable assets and precision equipment.
Features of HFCs Systems
- Rapid fire suppression typically within 10 seconds
- Doesn't contain chlorine or bromine, making it less harmful to the ozone layer compared to Halon 1301 and Halon 1211
- Electrically non-conductive and leaves no residue after discharge
- Safe for use in occupied spaces when properly designed
- Requires minimal storage space compared to inert gas systems
- Recognized and approved by international standards organizations
Applications
- Data centers and server rooms
- Telecommunications facilities
- Control rooms
- Museums and archives
- Electrical equipment rooms
- Medical facilities and laboratories
- Marine engine rooms
- Aviation facilities
- Libraries and document storage
System Design Considerations
Both inert gas and HFC systems utilize a total flooding approach to fire suppression. The choice between these two types of systems depends on factors such as:
- Space constraints for agent storage
- Environmental considerations
- Required discharge time
- Cost considerations
- Specific hazard requirements
