Water has always been a medium to put out fires. Without this precious resource death from fires would be inevitable. The conventional way to fight fires is with the installation of sprinklers by the process of wetting or cooling combustible surfaces with large water droplets. With a traditional sprinkler system the droplets will not absorb enough energy to evaporate and they quickly fall to the floor as water.
High-pressure water mist systems are a very interesting alternative to conventional sprinkler systems, particularly for the fire protection of large commercial buildings such as hotels and hospitals. Water mist systems are not only environmentally friendly but also more effective than conventional extinguishing systems. This technology is an intuitive system which continues to grow in popularity.
High-pressure water mist systems represent the latest in mist technology. What it aims to project is to use the same method as traditional sprinklers have but to add the effect of converting the water into steam. This system is a relatively low cost alternative to the typical sprinklers and are a perfect way to conserve water through the distribution of a fine mist.
The main advantage of a high- pressure water mist system apart from reducing the risk of fire spreading to other areas, is the reduction of the water damage it can do to your property. This is due to the low water consumption of the water mist system.
The small water droplets allow the water mist to control, suppress or extinguish fires by attacking two elements of the fire triangle: oxygen and heat. As well as removing the oxygen like the gas system, it simultaneously cools the fire like a traditional sprinkler by:
- Cooling both the flame and surrounding gases by evaporation
- Inertisation or local oxygen displacement
A water mist system has a number of parameters that dictate whether it will provide effective fire extinguishment and those are its spray dynamics, droplet size distribution and flux density. It vaporises water into micron sized particles to become steam, cooling the temperature and smothering the source of the fire. As high-pressure water mist both cools the fire and removes the oxygen, it results in quicker fire fighting.
The installation of a high-pressure mist system is far simpler than a typical sprinkler system. They are more aesthetically pleasing than a traditional sprinkler system which can look somewhat clumsy in an otherwise premium building.
High-pressure water mist systems are operated similar to other sprinkler systems either activated by an external fire alarm system or pressure drop in the pipe system. The whole system takes up little space and needs no special room or safe storage. High- pressure water mist systems use positive displacement pumps to provide standing pressures up to 150 bar. This requires high value components and the pipe work is typically stainless steel.
In addition high- pressure water systems are non-toxic. It also cleans fuel gasses from the air allowing the fire brigade to enter the extinguishing area quickly. To conclude, high-pressure water mist consistently delivers,being one of the most modern, highly efficient, eco-friendly systems in the industry to date.
