If you are looking for a leading fire safety solution, the HFC-125™ Gas Fire Suppression System offered by Koza Engineering combines technical excellence and reliability in one system.

Key Advantages

Fast and Effective Suppression: Detects fire in its early stages and acts within seconds.
Environmentally Friendly: A gas with zero ozone depletion potential (ODP), minimizing environmental impact.
Human Safety: Low toxicity levels ensure it does not pose a threat to human life.
Compact Design: Optimized cylinder systems for space-saving installation in small areas.
Versatile Applications: Ideal for data centers, telecommunications infrastructure, archive rooms, museums, laboratories, and areas with sensitive equipment.

How the HFC-125™ Gas Fire Suppression System Works

Fire Detection

The first step in the HFC-125™ gas suppression system is early fire detection. When fire detection sensors (smoke, heat, or flame detectors) identify fire indications in the environment, the system automatically activates, triggering the suppression process.

HFC-125™ Gas Distribution

• After fire detection, HFC-125™ gas is discharged from high-pressure cylinders and delivered to the fire zone through a piping network.
• The gas is stored in liquid form within cylinders and directed to the fire area.
• Nozzles or spray heads ensure rapid and efficient gas distribution throughout the fire zone.

Reduction of Oxygen Levels

• HFC-125™ gas reacts with the oxygen in the fire zone, significantly lowering oxygen levels.
• By replacing the oxygen necessary for combustion, it prevents the fire from sustaining itself.
• The system reduces the oxygen level to approximately 15-16%, effectively stopping the fire.

Heat Reduction and Fire Suppression

• HFC-125™ gas spreads quickly, disrupting the chemical reactions required for fire to continue burning.
• Cooling Effect: Rapidly lowers high temperatures, preventing the fire from spreading.
• Chemical Reaction Interruption: Inhibits the necessary chemical processes for combustion, effectively suppressing the fire.

Complete Fire Control

Once the fire is suppressed, HFC-125™ gas safely dissipates, leaving no residue and requiring no cleanup.
