Marioff HI-FOG® Fire Protection
Water Mist Fire Protection in Brief
A water mist system is a fire protection system which uses very fine water sprays (i.e. water mist). The small water droplets allow the water mist to control, suppress or extinguish fires by:
- cooling both the flame and surrounding gases by evaporation
- displacing oxygen by evaporation
- attenuating radiant heat by the small droplets themselves
The effectiveness of a water mist system in fire suppression depends on its spray characteristics, which include the droplet size distribution, flux density and spray dynamics, with respect to the fire scenario, such as the shielding of the fuel, fire size and ventilation conditions.
The use of water mist fire suppression, when compared to the use of gaseous agents and traditional sprinkler systems, has revealed advantages such as:
- Immediate activation
- High efficiency in the suppression of a wide variety of fires
- Minimized water damage
- Environmentally sound characteristics
- No toxic problems
Marioff is renowned for pioneering high pressure water mist fire protection technology for use in passenger ferries. Today, HI-FOG® protects people, property and business continuity in a wide range of applications both on land and at sea.
Why High Pressure Water Mist?
The NFPA 750 defines three pressure regions for water mist-generating technologies: low, intermediate and high pressure systems. Marioff’s rigorous testing procedures, combined with the company’s unrivaled experience, have shown that high pressure water mist consistently delivers:
- Better penetration into the seat of the fire
- Superior coverage of the protected volume
- An improved cooling effect from better mixing of gases and high evaporation rate
- Lower overall system weight
- Less water consumption
Sprinkler vs HI-FOG®
Fire Protection with Traditional Sprinkler System
Traditional sprinklers rely on water in order to perform, but unlike water mist they require the discharge of an enormous amount of water, predominantly in the form of large droplets, either in a protected space or directly on to equipment.
This often has implications such as water damage in the protected spaces and the need for a vast water supply due to the sheer amount of water required.
This automatically and justifiably creates concern among customers, as their valuable assets, or in some cases their production, are placed at risk – not only from fire, but also due to the fire protection system itself.
Fire Protection with the HI-FOG® Water Mist System
The HI-FOG® system is designed to both suppress and control fire, and its performance has consistently been proven to be better than or equivalent to that of traditional sprinklers. Furthermore, the amount of water used is significantly less, which results in far less water damage. What sets the HI-FOG® system apart from its competitors is the usage of micro-droplets, which represent water in its most effective fire fighting form. Yet another advantage of the HI-FOG® fire protection system when set against traditional sprinkler systems is that life cycle costs can be reduced due to its unique and intelligent design, which incorporates carefully-selected and durable materials.
