System Design

Efficient and effective​​

The highly-efficient AQUASYS firefighting system is ideal for a range of applications. The system consists of a high-pressure water supply unit combined with section and alarm valves, flow monitors, pressure switches, warning devices and AQUASYS high-pressure mist nozzles. A distinction can be made between a closed system and an open system in the system design:

Closed system

This system, which is mainly used in buildings, is characterised by its autonomous activation in case of fire. The entire pipeline system is filled with water and is set under a stand-by pressure, with the exception of the nozzles sealed with thermal tripping elements. An installed stand-by pump (IP) permanently maintains this pressure. Thermal tripping elements burst when they exceed defined temperatures and immediately release the high-pressure water mist (HPWM). The resulting pressure drop (alert via pressure switch [PS]) automatically starts the main pumps, which ensure that the HPWM system operates at full capacity. 

Open system

This system, which is preferred in industrial applications, is characterised by open nozzles, dry pipelines and the activation of predefined extinguishing sectors. The pipeline system is filled with water up to the section valves (DVS). When a warning is triggered by the detection system, the associated sector valve is activated and releases the water flow to all the nozzles in this sector. The resulting pressure drop (alert via pressure switch [PS]) automatically starts the main pumps, which ensure efficient firefighting across the entire section.
