Water extinction systems


Automatic sprinkler systems

How they work
Sprinkler systems are automatic fire extinction installations. They detect, warn of and control fires, and some types even extinguish fires that have already started before they spread and get out of control. The principle PEFIPRESA S.A. sprinklers work on is as simple as it is safe.

The sprinkler is installed according to a certain distribution in the areas to be protected. If a fire causes the temperature around the sprinkler to increase, exceeding its calibrated value, the sprinkler opens and the water is discharged in the area of the fire only. At the same time, the alarm system warns that the sprinkler has been activated.
When the fire has been extinguished, the open sprinklers are replaced by new ones and the system is ready to work again.


Types of special systems and accessories
To respond to the large number of applications, PEFIPRESA S.A. has developed several systems with special sprinklers and accessories, always with a view to providing optimum, made-to-measure fire protection, adapted to each particular building.





Fields of application
Warehouses, industries, production plants, storage areas, warehouses with self-supporting shelves, hotels, trade fairs, shopping centres, hypermarkets, supermarkets, office buildings, hospitals, food industries, cinema industries, photography, painting, detergents, plastics, paper and wood processing industries, galvanising work, waste treatment, data processing centres, extremely valuable archives and banks, among others.



Water spray systems


How they work
A water spray system basically works like a sprinkler system, except that it has open spray nozzles, and in case of fire it discharge large amounts of water all over the protected area. It is used for protecting either whole buildings or just parts of the buildings, and for localised protection of objects that are highly sensitive to heat or easily flammable and where there is a risk of fire spreading rapidly.



Fields of application
Nuclear power stations, thermal power stations, waste incineration warehouses, siloes, production plants, aircraft hangars, theatre stages, power transformer stations, cable tunnels, ferry boats, tunnels, gas and petroleum tanks, liquid fuel transfer stations, etc.






Foam extinction systems


How they work
Foam extinction systems are fixed systems. They are used for fires affecting solid and liquid materials, and, with certain restrictions, for those affecting gaseous materials. To generate the foam, the water flows through different units where it is suitably mixed with the substance that generates the foam, i.e. the foam-forming agent. The combination of water and concentrated foam is then almost always mixed with air.



Fields of application
Production and repair plants, storage plants in tanks, refineries, airports, laboratories, chemical warehouses, fixed roof tanks, floating roof tanks, spill pans, loading bays, hangars, LPG tanks, LPG spheres, etc.






Gas extinction systems


How they work
These extinction systems use inert natural gases to extinguish the fires. They are basically used where fires that have already started need to be extinguished quickly, and where it is essential to prevent subsequent damage caused by the effects of the extinction agents or residues.
In gas systems, the discharge is automatically triggered by detection of the fire, although it may also be activated manually. When the alarm is set off and the programmed delay has elapsed, the gas is discharged in the area of the fire. Any fans or air conditioning equipment will switch off at the same time, and the ventilation gates and doors will close to prevent air from entering or the extinction gas from escaping and losing its capacity.
Gas systems are particularly suitable for areas containing liquid fuels or other materials with a similar performance in the presence of fire, and for areas containing very valuable equipment or objects that could be damaged if other extinction agents were used.

Types of systems
To respond to the large number of applications, PEFIPRESA S.A. has developed several gas systems, always with a view to providing optimum, made-to-measure fire protection, adapted to each particular building. PEFIPRESA S.A. has developed the following gas extinction systems:

• High pressure CO2 "Favorit System"
• Low pressure CO2

Argon inert gas "Argotec System": the use of halons for fire extinction was prohibited under the Montreal protocol. PEFIPRESA S.A. has therefore developed an extinction system to fill this gap. Our system is called Argotec. It consists of 100% Argon and has NFPA-2001 IG-O1 denomination. Argon is supplied in cylinders with a 80/67 litre capacity at 200-300 bar. It therefore complies with the NFPA-2001 IG-O1 specifications and CEPREVEN Technical Standards. Its applications include generator rooms, main low voltage switchboards, computer rooms, etc.

Fields of application
Paint manufacturing and processing, hazardous materials warehouses, powder paint bath cabins, hydraulic systems, filters, printing presses, plastic foams, data processing centre installations, archives, underground cabling, control panels, turbines, transformers, metal processing, machine tools, textile machinery, art warehouses, etc.
