System: Low pressure water mist system

Low pressure water mist system

Product description

The low-pressure water mist system (NDWN) is an environmentally friendly alternative to many conventional extinguishing methods and is used in many different areas. Due to the lower consumption of water and electricity, it works very efficiently. The water mist generated by pressure and special nozzles fights fires particularly well and quickly due to its high cooling capacity and the effect of oxygen displacement.

The compact design means that the low-pressure water mist system can also be installed in areas with little space, such as test stands or transformer stations. Low operating and maintenance costs enable low-cost operation.

On customer request, this system can be designed in combination with an early fire detection system to form a system solution.
