Product Description

Inert gas nitrogen fire extinguishing system

Inert Gas IG100 Fire Suppression System Cylinder Volume 80L 140L Enclosed Flooding




IG-100 uses Nitrogen for a clean, safe and 100% ecological extinguishing. This gas is widely used in variety of extinguishing systems due to its excellent pressurization conditions.


In this case it complies with equal smothering efficiency by reducing the oxygen concentration to extinguish the fire, while leaving a percentage of oxygen suitable for occupied areas. Because of this feature, people can be protected where there is the possibility if they are in the enclosure area at the time of the fire, ensuring their safe evacuation both in terms of the level of oxygen in the room, and the absence of chemicals in the discharge. In addition, its physical and dispersion properties help maintain visibility during the evacuation.

We always pack it with polyfoam first and then put it into a wooden case. Sometimes, in order to meet with customers or the safety requirement, we will make a pallet for the goods.

  • Compared with the traditional 15MPa system, the number of fire extinguishing agent cylinders can be saved by 25%-50%.
  • The building area between cylinders is effectively reduced, and the overall occupation and utilization rate of the building are improved.
  • Constant 6MPa low pressure release can reduce the cost of pipeline and pipe fittings.
  • The constant release pressure of 6MPa provides more lasting and effective pressure, and the transmission distance can reach 200 meters.
  • The release of the whole system with low pressure can only have a less impact on personnel on sites, equipment and building structure and it is more safety.
  • The external constant pressure reliever can only bear the pressure when the system is spraying, which is convenient for dis-assembly and maintenance and effectively reduces the failure rate of the system.
  • After spraying, the system does not need to replace any parts, simple dis-assembly and secondary filling, the system can be quickly put into operation.
  • The opening area of the pressure-relief device is reduced. the input cost of the pressure-relief device is directly reduced, and the safety buckle is installed and arranged more simply.
  • Nitrogen fire extinguishing system(IG-100) can be widely used to make rapid response to fire, protect staffs on sites, sudden fire, important places sensitive to chemical reaction and effectively protect the safety of personnel and property.
