Water Mist Systems vs. Fire Sprinklers – Choosing the Best System
Water mist systems use fast water droplet vaporization, leading to air displacement, cooling, air/fuel vapor dilution and heat radiation reduction, and wetting of the fuel surface.
Fire sprinkler systems are a common sight these days. They are widely used by builders and vendors to protect the building from a fire accident. They work by putting out or slowing the spread of fire by drenching the entire area with water, this removes flammable and other fuel sources from supporting the fire.
On the other hand, water mist systems work by using exceptionally 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 while also displacing oxygen by evaporation. Both systems use water in different ways. The main difference is the size of the water droplets.
— Basic Understanding
Water Mist Systems
Water mist suppression systems have droplets with a diameter of fewer than 1,000 microns each. Released droplets are a fifth in size of the droplets released by the standard sprinkler system. This allows a water mist system to spray huge water surface area so it can lower temperatures.
— Purpose of Mist
Micro Mist can easily absorb more heat per unit to cause flames’ temperature to drop down faster than larger water droplets found in traditional sprinkler systems. Water Mist also displaces the oxygen in the room so that the fire gets suffocated and eventually extinguished.
— Types of Mist pressure systems
All water mist systems produce delicate sprays using water. These are available in the following types:
- Low-pressure system – 175 PSI or less
- Intermediate-pressure systems – 175 to 500 PSI
- High-pressure systems – exceeds 500 PSI
You can choose any of the above systems according to your unique needs.
— Basic Understanding
Fire Sprinklers
Fire sprinkler systems release water droplets with a diameter larger than 1,000 microns each. These droplets are five times larger than those released by water mist systems. The larger droplets ensure a direct application of water to the fire, effectively controlling and extinguishing it.
— Purpose of Sprinklers
Traditional fire sprinklers utilize larger water droplets that can penetrate through flames and reach the burning materials directly. This helps to cool the fire’s fuel sources and reduce the fire’s intensity. Additionally, the water spray helps in dampening surrounding areas to prevent the fire from spreading.
— Types of Sprinklers
All fire sprinkler systems are designed to release water to control and extinguish fires. They come in the following types:
- Wet Pipe Systems: Always filled with water, these systems provide a quick response to fire.
- Dry Pipe Systems: Filled with pressurized air, water is released into the pipes only when a fire is detected.
- Deluge Systems: All sprinklers in the system open simultaneously when a fire is detected, releasing a large volume of water.
- Pre-Action Systems: These systems require a two-step process to release water, reducing the risk of accidental discharge.
You can choose any of the above systems based on your specific fire protection needs.

Differences
- Water mist systems may have multiple or single orifices.
- Water mist sprinklers can also discharge additives, various gas agents, and air if desired.
- Water mist systems use fast water droplet vaporization, leading to air displacement, cooling, air/fuel vapor dilution and heat radiation reduction, and wetting of the fuel surface.
- Water droplets released are less than 1000 microns in almost 99% of the water mist system.
- Most water mist systems do less damage and are easier to clean up.
