General information
In case of fire outbreak, nitrogen is automatically supplied into the volume affected by fire. This ensures quick and reliable fire extinguishing without causing any harm to equipment or personnel. The design of the nitrogen fire fighting plant also provides for utilizing the nitrogen produced for purging process volumes, with automatic replenishing of nitrogen reserves.
Nitrogen fire fighting has a number of objective advantages associated with its simple installation, easy maintenance and high economic effectiveness.
