Lösungen/Water-based extinguishing systems

The first sprinkler systems emerged in the mid-19th century in the American textile industry to prevent fires caused by highly flammable cotton. An open pipe network that was manually filled with water in the event of a fire provided effective protection for the first time.
Over time, sprinkler systems were further developed and deployed across many sectors. The term ‘sprinkler’ still refers to the unit consisting of a nozzle, a closure, and a heat-sensitive triggering element.
Since its founding, ACCURO has been deeply involved in sprinkler technology, having planned and installed numerous systems while combining expertise, commitment, and flexibility. Today, the company designs and builds systems in accordance with all common standards such as VdS, TRVB, FM, and NFPA.

Deluge water spray systems are the ideal choice when rapid fire spread is expected within buildings or specific rooms. Unlike sprinkler systems, which activate only directly above the fire source, water spray and deluge systems distribute extinguishing water across the entire area. This allows larger technical installations to be effectively cooled and reliably protected from damage.
Another advantage: in addition to extinguishing the fire, water spray systems also contribute to smoke scrubbing during an incident. This improves visibility, reduces smoke-related hazards, and significantly enhances personnel safety.
Technically, water spray systems are based on the same principles as sprinkler systems. They consist of fixed pipework, nozzles, valve stations, release mechanisms, and a reliable water supply. The crucial difference, however, is that the nozzles in water spray systems are not closed but remain permanently open. As soon as the system is activated, water is discharged simultaneously from all nozzles, covering the entire protection area with a dense water curtain. This ensures that the affected area is fully wetted and efficiently cooled within the shortest possible time.
In the event of a fire, individual system sections can be activated automatically—electrically, pneumatically, or hydraulically—or triggered manually.

High-pressure water mist systems are among the most advanced technologies in preventive fire protection. Unlike conventional sprinkler systems, they operate with ultra-fine water droplets measuring only around 50 micrometres in diameter. At pressures between 35 and 140 bar, the water is transported through stainless-steel piping to specially designed nozzles, where it is evenly distributed throughout the protected area to form a fine, suspended mist.
This water mist rapidly cools both the fire source and the hot combustion gases. At the same time, it effectively binds smoke particles, improving visibility and reducing the concentration of hazardous substances in the air. The quick reduction in temperature enables fire services and emergency crews to enter the affected area much earlier and with greater safety — a decisive advantage in an emergency.
The required operating pressure is generated either by high-performance high-pressure pumps or, alternatively, by pressurised gas cylinders. Thanks to the optimal droplet size, the water mist penetrates deep into the fire source, prevents further spread of the flames, and significantly lowers the ambient temperature within a very short time.
 

Low-pressure water mist systems represent an innovative advancement of traditional sprinkler technology. They reduce the amount of extinguishing water required by up to 85% compared with conventional sprinkler systems — while operating at a maximum pressure of only 16 bar.
Thanks to their specially engineered nozzles, the extinguishing water is applied with exceptional efficiency and precision. This significantly reduces water damage to sensitive and high-value assets. Low-pressure water mist systems are also an excellent solution for buildings with limited water supply, restricted space for pipework, or for retrofitting in older and existing structures.
