IG-541 Fire Suppression System
The Flarenix IG 541 Fire Suppression System is a high-performance, environmentally friendly inert clean agent fire suppression system, designed for critical infrastructure and mission-critical applications. Composed of 52% nitrogen, 40% argon, and 8% carbon dioxide, this natural, non-toxic, and residue-free extinguishing agent provides effective fire suppression while ensuring safety for occupied spaces.
The IG 541 fire suppression system works by reducing the oxygen concentration in the protected space to a level that prevents combustion while remaining safe for human occupants. Unlike CO₂-based suppression systems, IG 541 allows personnel to remain in the area without the risk of asphyxiation. Additionally, compared to synthetic agents like FM200 or Novec 1230, IG 541 is naturally occurring, making it cost-effective, environmentally sustainable, and free from chemical regulatory restrictions.
With a working pressure of 15 MPa (2175 psi) and discharge design concentrations of up to 43.9%, the system ensures rapid, uniform suppression across enclosures, making it ideal for total flooding applications. The Flarenix IG 541 system meets NFPA 2001, UL, and FM standards, ensuring reliable fire protection for high-risk environments.
Key Features
- 100% Natural Inert Gas Fire Suppression – A non-toxic, eco-friendly gas blend (N₂, Ar, CO₂), safe for occupied spaces.
- Residue-Free, No Cleanup Required – Unlike chemical agents, IG 541 leaves no residue, making it ideal for sensitive electronics, clean rooms, and data centers.
- Designed for Total Flooding Applications – Suppresses fires by reducing the oxygen concentration below combustion levels without posing a risk to occupants.
- Optimized for Large & Multi-Zone Protection – The system’s high-pressure storage (15 MPa) allows for long pipe runs, ensuring uniform suppression across extensive facilities.
- Highly Intelligent & Configurable – Supports independent or distributed system configurations, providing flexible protection for single or multiple enclosures.
- Meets NFPA 2001, UL, & FM Certification Standards – Compliant with global fire safety regulations, ensuring reliable performance in regulated industries.
- Flexible Activation Methods – Supports automatic, manual, and emergency mechanical activation, ensuring rapid response to fire events.
- Cost-Effective & Low Maintenance – IG 541 has an unlimited shelf life, no chemical breakdown, and requires minimal ongoing maintenance compared to FM-200 or Novec 1230.
