Aqua mist system
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.
Typical applications, we see them going into some data centers out there, museums and theaters. Some historic homes have chosen water mist systems to have less water damage, and then large office buildings, so buildings companies are building that are high technology users.
Low pressure 2000 system fires with significantly less water but just as effectively as traditional sprinkler systems. Using high pressure and specialized sprinkler and spray heads, the water is dispersed as small droplets. This remarkably increases the overall surface of the water. Among the advantages of using this system is that it does not affect the nature and quality of products – devices, machinery and operating equipment, the possibility of dealing with different media (fuel – furnaces – flammable liquids – electricity … etc.) Where the fire triangle is dealt with water and it is in its gaseous state, thus avoiding affecting products, equipment and devices. One of the advantages of using this system also compared to other firefighting systems is the economical consumption of the water used in the control (2000-6000 square meters / liter of water, while in other systems it is 2 square meters / liter of water, and thus the losses resulting from the use of water are almost negligible.
Low pressure water mist systems
Some Of The Advantages Compared To Standard Sprinkler Systems:-
Smaller diameter & more flexible pipe work.
Less potential water damage to buildings or it’s contents.
Suitable for most types of fires, i.e. Liquids, fats, etc.
Quicker & easier installation making the system less expensive, so is more affordable.
Large capacity water storage tanks are not required.
Pre packaged plant equipment, utilising off site manufacture and in-time delivery therefore saving time on construction programme.
Self sufficient systems.
•99% of droplets smaller than 1mm (NFPA 750)
•Non-toxic, environmentally friendly
•Very high specific heat capacity
•335 kJ to raise 1litre water from 20C to 100C
•2257kJ to turn it into steam
•Then expands 1640 times
