Water Mist System Vs Sprinkler System

Water mist systems also minimises damage from smoke and fire.

Water mist system vs sprinkler system. However water mist suppression systems improve on this basic process by producing a finer spray or mist than a standard fire sprinkler nozzle. Water mist nozzles may have single or multiple orifices. The water droplets are less than 1000 microns in 99 of the water mist system while fire sprinkler systems have no limitation on droplet size. High pressure water mist penetrates a fire in liquid form which results in cooling and evaporation which controls a fire.

It is very efficient using significantly less water than traditional sprinkler systems while achieving a similar or better level of performance. They are a terrific way to conserve water through the distribution of a fine mist which has a wider radius than traditional sprinklers or nozzle hose systems. Use on various types of fires. A fine mist is a very effective way of ensuring that water evaporates quicker thus slowing down the combustion process even more effectively than a.

This is the process for any sprinkler system. The savings in potential damages via water mist can sometimes outweigh this drawback but the initial costs remain high. Water mist systems are designed to at worst suppress and at best to extinguish. In all cases this is sufficient to completely extinguish the beginnings of a fire and in turn minimises the damage to a households material posessions.

With the above similarities nonetheless sprinkler and water mist systems do have the following differences. The k factors of water mist nozzles are much smaller. Water mist systems discharge less water than sprinkler systems. 2 sprinkler water discharge k factors range from 43 to 475 lpm bar1 2.

High temperatures and low humidity will optimize the cooling effects generated by water mist systems. Water mist nozzles operate at the early stages of a fire and only discharge 10 20 of the amount of traditional water sprinklers. Damage to property and clean up is less with water mist suppression the average water mist droplet has a surface area that is 100 times greater than the volume of water released from a sprinkler system so they offer more effective fire suppression. There are two types of water mist systems.

1 sprinklers typically have only single orifices. Smoke control scrubbing various studies have shown that water mist systems do provide a degree of smoke scrubbing a cleansing whitening of the smoke whilst sprinklers are known to push the smoke layer to low level. Misting systems have been in use for decades.
