HI-FOG® is the world’s leading water mist fire protection technology. This innovative system combines the extinguishing characteristics of water with the penetrative qualities of gases - while posing no danger to people or the environment. HI-FOG is the water mist brand of Marioff.
In the HI-FOG system, high pressure is used to produce a fine mist with smaller droplets and a greater surface area than traditional deluge systems. The droplets absorb heat efficiently through vaporization. The system suppresses the fire by removing two of the main elements it needs to survive – heat and oxygen – and uses 70-90 percent less water than traditional deluge systems.
HI-FOG uses pure water, making it completely safe for people and the environment. The water is delivered through stainless steel tubes that are much smaller in diameter than the pipes used in traditional sprinkler systems. These smaller pipes make installation easy and are particularly suited for retrofits, where space is often limited.
Developed more than twenty years ago, HI-FOG is a proven fire suppression technology. More than 1,000 passenger cruise ships, including every major ship built since 2002, are protected with HI-FOG. The system’s excellent performance and low total system weight have made it the industry standard for marine applications. On land, HI-FOG protects approximately 1,500 installations, including road tunnels, metro stations and trains, hotels, factories, energy facilities, heritage buildings, data centers and hospitals.
