Water Mist System Vs Sprinkler System

Water mist systems do less damage and are easier to clean up than fire sprinkler systems.

Water mist system vs sprinkler system.

High temperatures and low humidity will optimize the cooling effects generated by water mist systems. 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. 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.

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. 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. 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. Use on various types of fires.

This is the process for any 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. 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. Water mist nozzles may have single or multiple orifices.

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 systems are designed to at worst suppress and at best to extinguish. 1 sprinklers typically have only single orifices. Water mist systems discharge less water than sprinkler systems.

High pressure water mist penetrates a fire in liquid form which results in cooling and evaporation which controls a fire. Misting systems have been in use for decades. With the above similarities nonetheless sprinkler and water mist systems do have the following differences. It is very efficient using significantly less water than traditional sprinkler systems while achieving a similar or better level of performance.

2 sprinkler water discharge k factors range from 43 to 475 lpm bar1 2. The k factors of water mist nozzles are much smaller. Water mist systems also minimises damage from smoke and fire.
