Water Systems
Water-based fire protection systems
Sprinklers, deluge systems, water sprays and traditional hydrants for environments where water is indicated as an extinguishing agent.
‘Eco-tradition’ fire protection systems and equipment
Sprinkler, deluge, hydrant systems
Water has traditionally been the natural resource of choice for extinguishing fires. Continuous technological evolution has produced increasingly complex and high-performance fire-fighting solutions over the years that continue to use it as an extinguishing agent.
Widely used in fixed or mobile systems, water continues to be a highly reliable and absolutely the most environmentally friendly fire-fighting solution.
The water-based fire-fighting technologies we develop:
- Sprinkler systems
- Deluge systems
- Fire hydrant systems
How it works
Sprinkler systems
Among the water fire-fighting systems, the most used for their reliability are sprinklers, automatic and localized extinguishing systems.
The main advantage of sprinklers is that they offer global coverage, ensuring localized intervention, in order to extinguish the fire at the initial stage or to limit it to prevent its propagation. These systems are characterised by a water supply, a control station and a network of piping that brings water to nozzles equipped with a temperature-sensitive sealing device, located in specific positions, in order to detect the presence of a fire.
Sprinklers can be wet, dry or hybrid.
The criteria according to which a sprinkler system is designed are always based on the type of use of the areas to be protected, the fire load and the level of combustibility (ability to quickly develop an intense and extensive fire) of the materials present.
Each system we offer is designed and built in reference to NFPA and UNI regulations.
Deluge systems
Technically similar to sprinklers, deluge systems are characterized by a control station, whose implementation is started by the detection systems (heat, flame, smoke, flammable gas) installed in the same area where the protection is planned.
Unlike what happens with sprinklers, however, the deluge valve, once opened, feeds the entire network, created by branches and nozzles (normally open type), dispensing the extinguishing agent simultaneously from all the nozzles and therefore over the entire protected area, regardless of where the fire started. Furthermore, it is possible to obtain higher performances when the water is added with chemical agents, since by reducing its surface tension, its penetration and diffusion properties increase.
Fire hydrant systems
The fire hydrant system consists of:
- a water supply
- a network of fixed pipes
- one or more delivery connections for a fire engine, in order to be able to introduce water into the network during emergencies
- hydrants and/or hose reels
- shut-off valves, particularly useful for the maintenance purpose of sectioning the system without putting it out of service.
Each hydrant, whether it is an above-ground, underground or wall-mounted column, is equipped with at least one flexible pipe and a dedicated delivery nozzle. The hydrants are appropriately located on the basis of a specific fire risk assessment, in order to supply water in adequate quantities to fight the largest fire (maximum incidental condition).

How does a sprinkler system work and what variants are available?
Sprinkler systems are automatic fire suppression systems that provide overall coverage and intervene promptly in the
initial stage of a fire to prevent it from spreading. They consist of a water supply, a control station, and a piping network
that carries water to discharge devices equipped with a heat-sensitive activation element. They can be configured in
three variants: wet, dry, or hybrid.
What criteria are used when designing a sprinkler system?
Each system is custom-designed according to the specific needs of the area to be protected. The main criteria
considered are the intended use of the areas, the fire load, and the combustibility of the materials present - in other
words, their ability to develop an intense and extensive fire rapidly. Each system is designed and built with reference to
NFPA and UNI standards.
What is the main difference between a sprinkler system and a deluge system?
Unlike sprinklers, which operate locally through heat-sensitive devices, deluge systems use discharge devices that are
normally open. The control station is activated by external detection systems - heat, flame, smoke, or flammable gas
detectors - and, once the valve opens, water is discharged simultaneously from all nozzles across the entire protected
area. For higher performance, water can also be mixed with chemical agents to increase penetration and diffusion.
What components make up a hydrant system and how is it distributed?
A hydrant system consists of a water supply, a fixed piping network, hydrants and/or hose reels - each equipped with a
flexible hose and discharge nozzle - shut-off valves for maintenance, and pump inlet connections for fire department
pumpers. Hydrant point distribution is based on a specific risk assessment, ensuring an adequate quantity of water to
fight the maximum foreseeable incident.
