FOGTEC - Open and Automatic Water Mist Nozzles

The heart of every FOGTEC system are special water mist nozzles. Due to a modular nozzle concept, nozzles can be provided covering standard applications or which can also be used in raised floors, suspended ceilings, areas with particularly high temperatures or that are exposed to wind conditions. Their reliability has been intensively tested such as at Factory Mutual. Water is atomised in special nozzle inserts placed in a nozzle body, allowing to vary the spray pattern (spay angle), flow rate and droplet distribution. When the activation is triggered by a fire alarm system A dry system (deluge system) with open nozzles is used where the pipe system is empty. Besides open nozzles, automatic nozzles are used that are activated like in a conventional sprinkler via a glass bulb. When activated via glass bulb nozzles, the pipe system is already pressurised prior to triggering by water or compressed air (wet, pre-action or dry pipe system)
