NATURA™ Inert Gas Fire Suppression System

Sustainable, Residue-Free Fire Suppression Using Naturally Occurring Gases

The NATURA™ Inert Gas Fire Suppression System is an engineered suppression solution that extinguishes fire by reducing oxygen concentration to a level that will not support combustion, all without leaving residue or producing by-products.

NATURA™ systems use naturally occurring inert gases, making them an environmentally responsible choice for protecting occupied spaces, sensitive equipment, and irreplaceable assets. By preserving visibility and eliminating cleanup after discharge, NATURA™ supports rapid recovery and continued operation in mission-critical environments.

When integrated with KiddeFenwal detection and suppression control platforms, NATURA™ delivers reliable, code-compliant fire protection tailored to the specific hazard and enclosure.

Key Advantages
  • Inert Gas Suppression Using Natural Components
    Uses naturally occurring gases to suppress fire without chemical agents or residues.
  • Environmentally Responsible Protection
    Zero ozone depletion potential and no greenhouse gas contribution from the agent itself.
  • Safe for Occupied Spaces
    Designed for use in normally occupied areas when applied in accordance with applicable codes and standards.
  • No Residue or Cleanup Required
    Leaves no residue or corrosive by-products, reducing downtime and post-event disruption.
  • Engineered System Flexibility
    Supports tailored system designs to match enclosure volume, hazard type, and operational requirements.

Applications

The NATURA™ Inert Gas Fire Suppression System is ideal for environments where sustainability, asset protection, and operational continuity are critical, including:

  • Data centers and server rooms
  • Control rooms and electrical spaces
  • Telecommunications facilities
  • Archives, libraries, and records storage
  • Museums and cultural institutions
  • Clean rooms and high-value industrial spaces
Applications for The NATURA™ Inert Gas Fire Suppression

NATURA™ Acoustic Nozzles 

For applications where sound levels during system discharge are a concern, NATURA™ Acoustic Nozzles provide a quieter alternative to standard suppression nozzles while maintaining the performance of the NATURA™ Inert Gas System. 

Designed for environments with sensitive equipment, including data centers and other high-value facilities, acoustic nozzles help reduce discharge noise without requiring bulky nozzle-silencer combinations. 

KEY BENEFITS

  • Reduces sound levels to below 110 dB (500 Hz–10 kHz) when measured 3 feet (1 m) from the nozzle  
  • Provides a more compact, aesthetically pleasing alternative to traditional nozzle-silencer combinations  
  • Can replace existing NATURA™ discharge nozzles without major pipe modifications, making retrofits straightforward  
  • Maintains standard NATURA™ nozzle spacing for simplified system design and installation 

Protecting Sensitive Equipment 

As data centers continue to evolve with increasing use of HDD and SSD storage, minimizing vibration and noise during fire suppression system discharge has become an important design consideration. NATURA™ Acoustic Nozzles help address these concerns while delivering the reliable fire protection performance expected from the NATURA™ Inert Gas System
