Nitrogen fire fighting units

The fire fighting plant is designed for extinguishing fires resulting from inflammation of various type combustible substances which cannot burn without access of air, for example, oil, oil products or gas condensate, within confined space and indoor areas, as well as for prevention of fire and explosion hazardous situations at oil and gas producing facilities.

The principle of nitrogen fire fighting plant operation is based on the inert properties of the produced air mixture with 95–99% nitrogen concentration. At this nitrogen concentration in the air, the burning process is rendered impossible. The gaseous nitrogen produced by the nitrogen plant gas separation unit is supplied under pressure into the receiver. The receiver volume is calculated on the basis of the volume of premises and tanks which fire safety is to be maintained by the plant.

Advantages of GRASYS nitrogen fire fighting plants

  • No damage is caused to equipment during fire extinguishing
  • Efficiency of fire extinguishing is not affected by fire hazard location
  • Maintenance of safe atmospheric composition
  • Full automation due to the use of the intelligent control system GRASYS Intelligent Control-8
  • Simple maintenance
  • Enhanced fail-safety
  • No refill required
  • Environmental friendliness
  • Low operating costs
  • Perfect design of membrane modules as compared with the existing market options
  • Reliable up-to-date compressor, making of the world leading producer
  • Operation within a broad temperature range

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.
