Nitrogen Fire-Fighting Units
Grasys manufactures nitrogen units to provide fire and explosion safety at various facilities. The operating principle of a nitrogen fire-fighting unit is to create an inert atmosphere with a high nitrogen content, which makes combustion impossible.
Capacity
up to 5,000 m3/h
Gas purity
up to 99.9%
Warm-up period
up to 10 minutes
Operating temperature
–50 to +40 °C
Applications of Nitrogen Fire-Fighting Units
The nitrogen fire-fighting unit is designed to extinguish fires caused by the ignition of various combustible substances that cannot burn without air access, such as oil, oil products or gas condensate, in confined spaces and premises, and to prevent fire and explosion hazards in oil and gas production facilities.

Operating Principle of a Nitrogen Fire-Fighting Unit
The operating principle is based on the inert properties of the generated air mixture with a nitrogen content of 95–99%. Such level of nitrogen in the air makes combustion impossible. The gaseous nitrogen generated by the membrane gas separation unit of the nitrogen fire extinguishing unit is pressurised into a receiver whose capacity is calculated on the basis of the volume of the rooms and reservoirs to be protected by the unit.
Product Design Options
Fixed Design
Free equipment placement, on-skid or on-platform design.
Packaged Modular (Transportable)
Modular container or sea container design. Operation in various climatic zones.
Truck-Mounted
Designed on a trailer, skids, as well as in a self-propelled version based on the KamAZ and URAL chassis.
Prefabricated Building
Modular frame building using light steel thin-walled structures and sandwich panels.
General Description
In the event of a fire, nitrogen is automatically injected into the space in which the ignition has taken place. This ensures that fires are extinguished quickly and reliably, without damage to equipment or personnel. The nitrogen fire-fighting unit can also be used to purge the process volumes, with the nitrogen generated being automatically replenished.
Nitrogen fire-fighting units have a number of objective advantages due to their ease of installation and maintenance and high cost effectiveness.
Applications of Grasys Nitrogen Fire-Fighting Units
- Creating an inert atmosphere in process tanks in the oil and gas industry
- Creating an inert atmosphere in storage facilities for flammable substances in various industries
- Creating an inert atmosphere to prevent explosions in coal mines
- Fire extinguishing in museums, galleries, exhibition halls, archives, bank vaults
