Special water mist nozzles are the heart of every FOGTEC system. They are optimised for specific applications and have undergone extensive testing with independent testing houses such as Factory Mutual, to ensure their reliability.

FOGTEC water mist nozzles are subjected to a 100 % quality test. Each individual micro-nozzle, within the main nozzle body, is furnished with an individual filter.

Open type nozzles are installed in dry pipe deluge systems. All nozzles of a group will be activated at the same time after the FOGTEC system has received a signal from a separate detection system.

The piping to automatic nozzles is normally water filled (wet) except in the case of freezing possibility, where piping may be pressurised by air (pre-action) from the section valve. The nozzle is equipped with a glass bulb which breaks when head is detected.

The modular nozzle design concept allows the use of both standard application nozzles and special applications nozzles for false floors, ceiling voids, zones with particularly high temperatures, areas exposed to the wind, etc.
