DNX CNF 750 - Cabinet extinguishing for up to 1,5 m³

DNX Series is a solution for detection and exthinguishing in closed cabinets. With an integrated EN 54-20 Aspirating Smoke Detector within the cabinet a fire is quickly detected and an automated extinguishing starts. To extinguish the fire one DNX Cool Gas Generator is required with this variant. The Cool Gas Generator have solid stored nitrogen which creates 750 l pure nitrogen in case of activation which is suitable for up to 1,5 m³.

As there is not pure nitrogen stored, there is low pressure with the system and now test or maintenance of the Cool Gas Generator is required. Due to the usage of nitrogen and low pressure no defects within the cabinet are expected. The oxygen concentration within the air is reduced to less than 11,5 % and a fire is eliminated.
