Ultra Fog Fire Extinguishing System vs. Traditional Sprinkler System

Table of content Introduction 01. About Traditional Sprinkler System 02. About Ultra Fog Fire Suppression System

Introduction Water has been very well known as a fire extinguishing agent for as long as man has used fire. Why is water so effective as a fire suppression medium? Water has a very high specific heat capacity - it can hold more heat than any other everyday liquid- this is why it is used in central heating systems in our houses. Fire can only exist when there are sufficiently high levels of fuel, oxygen, and heat to sustain combustion. Automatic water sprinkler heads were commercially available since the mid 19th century. Still, the technology of high-pressure water mist evolved in the 1980s...

01. About Traditional Sprinkler System Traditional Sprinkler Systems were available for commercial sale since the mid 19th century. They use water to perform, however, the form of water distribution is different than for Ultra Fog Fire Suppression Systems. Sprinkler sprays are composed of droplets. The number of droplets of each size depends on the sprinkler design, water pressure and location in the spray. In traditional sprinklers, the typical diameter of each droplet is 1mm or larger. At that size, 1 litre of water produces approximately 1.9 million droplets, having a total surface area...

02. About Ultra Fog Fire Suppression System Ultra Fog water mist fire suppression systems provide robust, effective, quality engineered solutions for applications that require optimal fire suppression while minimising the volume of water consumed and deployed. High-pressure pumps force water through the stainless steel Ultra Fog water mist nozzles, discharging the water in the form of millions of tiny droplets – typically 30 – 200 μm diameter. At that size, 1 litre of water produces approximately 4 billion droplets, having a total surface area of 75m². An activated system creates a blanket...

Water mist systems provide absolute protection for many kinds of enclosures. This occurs because the nebulised droplets and the oxygen present in the enclosure affect the base of a fire. When the water mist turns into steam, it expands in volume by 1700x, reducing the concentration of oxygen available to the flame. This process of evaporation is a consequence of the absorption of heat from the fire, thereby cooling the fire. Water mist reduces two components of „fire triangle”. Fire is not able to exist without sufficient levels of oxygen and heat. The triangle-based formula for...

03. Comparison Water mist fire protection systems share many similarities with sprinkler systems. Both systems use water as the suppression medium, pumped through a network of pipes and zone valves, and deployed within the affected area via ceiling or wallmounted heads. The main difference is the working pressure of each system. While sprinkler systems typically operate below 12 bar [175 psi], high-pressure water mist systems operate within the range of 35 – 120 bar [500-1740 psi]. Sprinkler systems typically work by drenching the surfaces of the fuel and surrounding surfaces; water mist...

Lower water consumption also enables water mist systems the use smaller diameter distribution pipework compared with sprinkler systems. ULTRA FOG® water mist systems typically utilise 12mm, 22mm, 28mm, and 42mm outside diameter stainless steel pipework. This saves space within ceiling voids – which are often shared with and occupied by the building’s HVAC, water main, drainage, lighting, communication, and power cable conduits. The use of small diameter pipe also simplifies the installation of the system and coordination of the pipework amongst the other services throughout the building....

An example of this is within the residential sector, where exists an ever-increasing need for housing, limited space to build; increasingly stringent energy efficiency targets; and an ever-present need to conserve water. Within urban environments, this is fuelling the rapid development of modern high rise buildings, the refurbishment of existing residential tower blocks, and in some cases, the redevelopment and change of use of office blocks into residential dwellings. While new-build high rise buildings are generally required to be equipped with an active fire suppression system, at...

Ultra Fog Fire Suppression System Traditional Sprinkler System 3 - dimensional area of coverage - Bigger drops are only covering water mist penetrates areas easier area below traditional sprinkler, than traditional sprinkler system. Droplets suspended in the air can fill the entire volume of the room not penetrating other areas. 80 - 90% less water used in Traditional Sprinkler Systems use more water than the Ultra Fog sprinkler system Water Usage Nozzles can be tested without breaking frangible glass bulb. Test may be performed by any competent person, as Ultra Fog Test Tool is easy Fire...

04. Conclusion Traditional sprinkler and Ultra Fog water mist system are both proven fire suppression technologies. The method by which they suppress fire is slightly different. Sprinkler systems use large volumes of water to wet the surface of the fuel. Water mist uses smaller volumes of water to cool the hot, flammable gases released from the fuel. Better efficiency and shorter time needed to extinguish helps to reduce the quantity of toxic gases produced by the fire. The small water amount used while putting out a fire contributes to minor damage. Compared to sprinkler systems,...
