WHEN SAFETY IS TAKEN SERIOUSLY
Low pressure water mist is the automatic fire suppression system of the future.
Prevent Systems researches, develops and distributes our own patented low pressure water mist technology.
We are a market leader with more than 25 years of experience within the field.
PRODUCTS
Automatic low pressure watermist fire suppression systems from Prevent Systems are designed for the fire protection of lives, buildings and/or specific equipment. The systems have been tested and documented for Residential and Domestic applications, as well as of Ordinary Hazard classes OH-1, OH-2 and OH-3. Please see respective datasheets for details and limitations.
The typical water mist system consists normally of these three main components:
- Watermist nozzles, which produces and distributes the watermist that suppresses a fire in an activated area.
- A pump-set to increase the water pressure from the town mains or water tank.
- Pipes & fittings to distribute the water to the nozzles.
NOZZLES
Nozzles from Prevent Systems are available both as ceiling and wall models. The nozzles are approved for Residential and Ordinary Hazard applications OH-1, OH-2 and OH-3. Please see the respective datasheet for details and limitations.
PIPING SYSTEMS
Water mist solutions from Prevent Systems are installed with corrosion-free piping systems, including Stainless steel pressfittings, RedPipe PP-R, CPVC and PrevPex, a customised water leakage proof and replaceable pipe-in-pipe system.
PUMP-SETS
Our pump-sets are developed in partnership with Grundfos, and are manufactured and delivered according to current standards.

WATERMIST
GENERAL INFORMATION ON WATERMIST
Watermist is defined as water droplets less than 1mm in diameter.
How does it work?
Water from the mains or a tank, flows through distribution pipework and is “atomized” to many very fine droplets, as it passes through a water mist nozzle. Many tiny water droplets create a greater total surface area per liter of water.
The smaller droplets absorb the heat from the fire, and lowers the temperature quickly. The fine droplets in and around the fire «boils» over from water to steam, or water vapor, which is an inert gas. This conversion to water vapor, dramatically increases the volume of water, up by almost 1700 times. The water vapor displaces the oxygen near the fire, and suffocates it.
The droplets that are not converted to water vapor, will wet the surrounding area and prevent the fire from spreading.
Effectively, the fire is attacked from all sides of the Fire Triangle – Heat, Fuel and Oxygen.
BENEFITS OF LOW PRESSURE WATER MIST
Exploiting water more efficiently has its’ obvious benefits;
- The systems demand less water, smaller water intake or tank
- Smaller dimensions on pipes and fittings
- Easier and faster installation and replacement
- Discrete and space-saving design in corrosion-free materials
- Low maintenance costs due to high quality corrosion free components
- Effective fire suppression solution that attacks all three sides of the fire-triangle simultaneously
- Non-toxic fire extinguishing with reduced water consumption
- Minimal interruption of the daily operation in case of fire
Easy and fast installation - Discrete and space-saving design
Since our systems require less water, the water intake or tank can be smaller, and all pipes and fittings are smaller. This results in easier and space-saving installations, a greater architectural advantage, which is important to builders, architects, contractors and owners.
Documented and certified
Prevent Systems water mist systems are fire tested in full scale fires at accredited fire laboratories according to international standards, with full documentation for applications to be protected. Our water mist nozzles were the first to be certified by LPCB and listed on RedookLive.com
Respects the environment
Low pressure water mist technology use small components, which require less amount of material to manufacture, and more eco-friendly to transport and store. All components are of high corrosion free quality, designed to last the life of the building without considerable need for replacement and maintenance.

ABOUT US
OUR HISTORY
INNOVATION SINCE 1987
The history about our innovative solutions goes back to 1987. Back then our current Head of Technology started developing water mist nozzles for fire suppression.
The systems were originally developed for the maritime sector and are found on board cruise liners, ferries and yachts all over the world. When founding Prevent Systems AS in 2007, the focus was shifted to the land-based market.
Our innovative solutions have made us a market-leader within research, development and distribution of automatic fire suppression systems with low pressure water mist.
Prevent Systems was the first company to meet the test requirements for the Nordic residential water mist standard, INSTA 900-3, and the British water mist standards for residential and domestic, BS 8458, and for low hazard occupancies, BS 8489. We were also the first company to obtain LPCB certification for water mist nozzles, listed on RedBookLive.com.
More than 25 years of research and development experience enables us to deliver innovative patented fire protection technology to the fast growing residential market, as well as for light- and ordinary hazard applications. This includes apartment buildings, care institutions, hospitals, hotels, office buildings, schools parking garages and cultural heritage buildings.
