Water Mist
fire suppression systems
Water mist fire suppression systems represent one of the most innovative and high-performing solutions in the field of fire protection for sensitive environments. These include areas where electronic equipment, valuable materials or limited space require solutions that permit penetration, a quick and effective response, and minimal collateral damage.
Unlike traditional water-based systems (such as sprinkler and deluge), these systems use atomized water in extremely fine particles, creating a dense mist that combats fires on multiple fronts.
An effective and beneficial technology
Effective on a variety of fire types
Water mist systems are particularly effective in containing and extinguishing fires in their early stages across a wide range of fire classes, including class A (solid materials), B (flammable liquids) and various types of risk scenarios.
Less water consumption
Thanks to the atomization of water into micro-droplets and their targeted distribution, water consumption is significantly lower compared to traditional systems, reducing collateral damage.
Minimal damage
Water mist and the absence of harmful chemical agents cause less damage to objects and equipment in the protected environment, allowing for a quicker return to operations.
In addition, using water as an extinguishing agent makes water mist systems safe for both people and the environment.
Flexible installation
Water mist systems can be installed in any environment and adapted to different configurations and a wide range of applications, from the protection of technical rooms to data centers and museums.
How it works
A water mist system works by generating a very fine water mist composed of tiny droplets with a diameter of less than 100 microns. These droplets are produced by a network of specially designed nozzles that atomize water pumped at high pressure, either through pump systems or pressurized gas cylinders (such as nitrogen).
The extinguishing action is achieved through different mechanisms:
- Cooling: Tiny droplets absorb heat quickly, reducing the temperature and slowing the spread of flames.
- Smothering: The mist saturates the environment with water vapor, reducing the concentration of oxygen available for combustion.
- Interrupting the chain reaction: Water particles interfere with the chemical reaction of combustion, breaking the chain of reactions that fuel the fire.

High Pressure Water Mist
0,01 mm ⇒ 200 m2
Design and installation
Water mist systems must be designed, installed and maintained only by qualified companies, and their use is limited to applications that have been specifically tested or for which the findings from test results of other applications are deemed acceptable by the regulatory authority.
The installation of water mist systems is subject to specific technical standards that define performance requirements, design criteria, and verification procedures, which vary depending on the country and the type of application.
It is therefore essential to ensure that the system complies with current regulations to guarantee maximum safety.
Industrial sector
The evolution of water mist technology in saturating environments and its ability to penetrate enclosed spaces (such as electrical panels) has matched the performance and characteristics of gas-based extinguishing systems. However, water is a natural, inexhaustible and low-cost extinguishing agent, making it suitable for specific industrial applications.

Marine sector
Water mist systems are the ideal solution for marine applications, where technical environments often have limited, confined spaces and special working conditions.
The possibility of having compact pump units, smaller tanks, and piping systems tailored to the various risks present on board allows for the control of fires across different risk classes, but most importantly, it minimizes damage after discharge.
