Sprinkler extinguishing system

Whether offices, museums or sales premises: Sprinkler systems extinguish specifically with water due to thermal triggering.

Sprinkler system - advice, installation & maintenance

Sprinkler systems belong to the classic and most common stationary fire extinguishing systems. They are automatically activated following a simple and safe operating principle: a network of pressurized pipes and sprinklers runs through all parts of the building to be protected. In case of fire, the sprinkler system extinguishes selectively with water. The sprinkler is closed by a coloured, liquid-filled glass tube which, depending on the individual specification, triggers at a temperature between 57 °C and 340 °C. The triggering temperature of the sprinkler system is set approximately 30 °C above the maximum expected room temperature. Only those sprinklers are triggered where a temperature difference is detected. The affected glass tubes burst, and the sprinklers release the pressurized extinguishing water. This water flows through the sprinklers, hits the spray plate and is distributed over the entire area. At the same time, water flow triggers alarm devices.

Sprinkler systems are frequently used in public buildings and facilities, retail outlets, office buildings, high-rise buildings, underground car parks, logistics areas, high-bay warehouses, industrial plants, museums, congress, and conference centres and other event locations.

The sprinkler system is available from CWS in three versions:

  1. Wet systems: These are under permanent water pressure, which enables an immediate extinguishing effect. They should only be installed where there is no danger of frost.
  2. Dry systems: The pressure in the pipeline network is constantly maintained by compressed air or nitrogen according to the manufacturer's specifications. Dry plants are used in areas at risk of frost.
  3. Pilot controlled dry systems: This sprinkler system only triggers when the fire alarm system is also triggered. This prevents the direct release of extinguishing water in the event of accidental damage to a sprinkler. The pilot-controlled drying systems are therefore suitable for particularly sensitive areas.

All variants of the sprinkler systems can be equipped with different types of sprinklers, such as umbrella sprinklers, sidewall sprinklers, or ESFR sprinklers (Early Suppression Fast Response).

We recommend using the CWS Fire Safety all-round carefree package for all sprinkler systems: CWS Fire Safety analyses the local conditions for you, plans and installs the sprinkler system professionally. We will gladly hand over the system to you as a “turnkey” solution and take care of regular maintenance.
