Fire Protection in Trains: Dedicated Ultra Fog Water Mist Solution

Fire safety in trains requires fast response, minimal water usage, and reliable performance in confined spaces. Passenger compartments, electrical cabinets, and technical areas present unique fire risks, while strict space and weight limitations demand compact, efficient systems.

Ultra Fog has developed a dedicated high-pressure water mist system for rolling stock, designed specifically to meet the operational and safety requirements of modern trains and metros.

Why High-Pressure Water Mist?

The Ultra Fog system uses high-pressure pumps and specially designed nozzles to create ultra-fine water droplets. When activated, the mist:

• Rapidly absorbs heat
• Reduces oxygen at the flame zone
• Suppresses and limits fire spread
• Uses significantly less water than traditional sprinklers

This ensures fast fire control while minimizing damage to onboard equipment and interiors - a critical factor in railway applications.

Supporting Modern Railway Safety Standards

With increasing safety regulations in the rail sector, operators require fire suppression systems that are certified, reliable, and performance-tested. Ultra Fog systems are the result of continuous research, development, and extensive fire testing, providing proven protection for transportation environments worldwide.

The system has undergone rigorous full-scale fire testing and complies with the 11565:2021 UNI standard.
