Our water-spray extinguishing systems for space and equipment protection.

If conditions are such that extremely rapid spreading of a fire can be expected, then Minimax water-spray extinguishing systems can provide maximum safety. Water-spray extinguishing systems operate with open extinguisher nozzles which, in the event of fire, distribute the extinguishing water over the entire protected area, the quantity of extinguishant needed being minimal. Spray extinguishing increases the surface area of the extinguishing water, entrains the heat of combustion and therefore cools the combustible substance. In addition to this cooling effect there is a smothering effect because the steam produced impedes the oxygen supply to the base of the fire.


Water-spray extinguishing systems are designed for space or equipment protection. In the case of space protection the extinguishing water is distributed evenly across the whole area of the fire hazard. The extinguishing nozzles are therefore arranged evenly spaced at ceiling level. In the case of equipment protection systems, defined objects particularly subject to fire hazard are provided with water spray for protection or for preventive cooling. The extinguishing nozzles are therefore arranged to be specifically aimed at the object. For tall objects they may also be installed at several levels.

In the event of a fire, the smoke/gas-entraining, cooling and radiant heat-reflecting effect of a water-spray extinguishing system also provides excellent protection for personnel.

The water flow is triggered by hydraulic, pneumatic or electrical devices arranged in the protected area or in the vicinity of the object and which activate the remotely-operated valve station in the event of a fire. Distribution of the extinguishing water is determined by the number, size and spray-characteristics of the nozzles and arranged to suit the objects and areas to be protected.
