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.
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:
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.
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.
Our pump-sets are developed in partnership with Grundfos, and are manufactured and delivered according to current standards.
Like having your own personal firefighter. Our water mist systems are highly efficient and developed in partnership with fire advisors and British Fire & Rescue Service.

The water mist solutions offer safety and security for its’ residents.
The solutions are for instance found in 500 apartments at The Bread Factory (Brødfabrikken) in Oslo, Norway.
Brødfabrikken, Løren in Oslo, Norway, will accommodate approx. 500 new apartments and office premises. The project is developed by Stor-Oslo Eiendom AS.
Nybyen Økern in Oslo is a new residential property with about 400 apartments. The apartments will be within walking distance to the new Økern Centre with shopping, movie theatres and an aqua park.
Extinguishing with water mist makes the following clean- up faster and ensures minimal interruption of daily operations.
Health and rehab centers
Solutions from Prevent Systems are discrete and merge nicely with architecture and interior.
For instance, the solutions are found in the Crowne Plaza Hotel in London.
Low pressure water mist ensures efficient fire protection of schools, kindergartens and other institutions. The solutions are for instance found in a school called Møllergata Skole in Oslo, Norway.
Offices, shops and other commercial premises are fire protected with low pressure water mist.
The solutions are found in several office buildings, e.g. Tykkemyr in Moss, Norway.
Retail and offices
Water mist solutions are easy to install and ensure safe protection.
For instance, the solutions are found in Windsor Castle in the United Kingdom.
Museums and community centers
Windsor Castle is the world’s largest inhabited castle. The castle has been home to 39 English monarchs and contains a large number of irreplaceable objects of art.
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.
Exploiting water more efficiently has its’ obvious benefits;
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.
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
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.
IWMA Member RISE have carried out fire tests with Residential Sprinklers and Water Mist
Prevent Systems AS – intro in English
Low Pressure Watermist in Residential House Demonstration
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.
