Fire sprinkler systems

Sprinkler systems are still the most widespread and effective water-based fire suppression systems today.
They are active protection systems that guarantee the supply of large amounts of water to fight and extinguish a fire in its initial phase or to control and contain flames so they can be extinguished with other systems.

Beneficial and safe technology

It's effective

Water has always been the most used resource for fire suppression. An easily accessible extinguishing agent capable of extinguishing and effectively controlling any type of fire.

The water-based firefighting systems designed and manufactured by Mozzanica are a reliable, thoroughly tested and guaranteed technology for fire suppression

It's fast

Fire sprinkler systems are designed to be able to intervene extremely quickly on the fire, automatically acting on the affected area to control the damage caused and reduce the risks to people and property.

It's inexpensive

Water is a low-cost and readily available natural resource and is not harmful to humans or the environment.

It can be stored within water reserves suitably sized to be immediately available in the event of a fire.

It's modular

Water systems are designed to adapt to the structural needs of the environment to be protected, even in geographical areas subject to a high seismic risk.

Types of sprinkler systems

Wet sprinkler systems

This type of system has pressurized water constantly present in the pipes and is ready to immediately and automatically discharge the water when heat causes the sprinkler heads to open directly above the area affected by the fire.

This solution is used when intervention speed is a priority and the operating ambient temperatures are above 4°C/39°F.

Main features

  • Operating temperatures above 4°C/39°F
  • High reliability


  • Closed garages
  • Shopping centers
  • High-density warehouses
  • Hospitals

Dry sprinkler systems

Dry systems have pipes filled with pressurized air or nitrogen that keep a dry alarm valve closed that holds back the water. If the sprinkler nozzles are opened, the air contained in the pipes is released, allowing the valve to open and the pipes to fill up with water.

This type of system is mainly used in low-temperature environments but has the disadvantage of having longer intervention times.

Main features

  • Pipes filled with compressed air or nitrogen


  • Very cold or very hot environments

Preaction sprinkler systems

Preaction systems are dry sprinkler systems combined with separate fire detection systems, such as smoke or heat detectors. They are a type of double-approval system; in order to be activated, they require both breaking the heat-sensitive element and activation by the detection system, with the advantage of preventing accidental discharges.

Main features

  • Reduced accidental discharges


  • Environments with particular critical issues and risks

Deluge sprinkler systems

Deluge systems do not have heat-sensitive elements and have a constantly open network of empty distribution pipes that is managed by valves that are activated by a smoke or heat detection system.

When the system is activated, all the nozzles open and start operating at the same time.

Main features

  • Fast interventions
  • High effectiveness
  • Large amount of water


  • Storage of explosive/flammable gases
  • Storage of combustible/flammable liquids
  • Hydrocarbon extraction and processing plants
  • Energy production plants, gas turbines and transformers
  • Marine applications in hangars, flight decks, machine rooms

ESFR sprinkler systems

These are systems that have special nozzles with extremely short response times (less than 30 seconds) to act promptly on a fire.

Main features

  • Immediate suppression
  • Fast interventions


  • High-density warehouses

CMSA sprinkler systems

This type of system ensures the delivery of a large amount of water quickly to fight fires in high-risk areas, such as storage facilities for flammable materials, tires, and waste.

Main features

Large amount of water


  • Industrial applications and Oil & Gas
