Water Mist System Vs Sprinkler System

Water mist systems also minimises damage from smoke and fire.

Water mist system vs sprinkler system.

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. 2 sprinkler water discharge k factors range from 43 to 475 lpm bar1 2. While water mist systems may reduce costs when compared with dry chemical or clean agent systems traditional fire sprinkler systems may still have a financial edge. 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.

Use on various types of fires. This is the process for any sprinkler system. 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. It is very efficient using significantly less water than traditional sprinkler systems while achieving a similar or better level of performance.

Water mist systems discharge less water than sprinkler systems. The k factors of water mist nozzles are much smaller. The savings in potential damages via water mist can sometimes outweigh this drawback but the initial costs remain high. 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.

1 sprinklers typically have only single orifices. Water mist nozzles may have single or multiple orifices. High temperatures and low humidity will optimize the cooling effects generated by water mist systems. Water mist systems are designed to at worst suppress and at best to extinguish.

Water mist nozzles operate at the early stages of a fire and only discharge 10 20 of the amount of traditional water sprinklers. There are two types of water mist systems. Misting systems have been in use for decades. 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.

However water mist suppression systems improve on this basic process by producing a finer spray or mist than a standard fire sprinkler nozzle. With the above similarities nonetheless sprinkler and water mist systems do have the following differences. 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.
