100% Pressurized Nitrogen Inert Gas Fire Suppression System with 30MPa Working Pressure for Enclosed Flooding

The IG-100 Inert Gas Nitrogen Fire Suppression System delivers clean, safe, and 100% ecological fire extinguishing. Utilizing nitrogen as the extinguishing agent, it is widely adopted across a variety of applications thanks to its excellent pressurization characteristics and reliable performance.

The system extinguishes fire by reducing the oxygen concentration in the protected enclosure to a level that suppresses combustion, while maintaining a residual oxygen level suitable for occupied areas. This allows personnel present at the time of a fire to be protected and to evacuate safely — both in terms of breathable oxygen levels and the complete absence of chemical residue during discharge. In addition, the physical and dispersion properties of nitrogen help maintain visibility throughout the evacuation process.

The system is highly recommended for Class A, B, and C fires. It operates by total flooding of the room, achieving discharge in 10 seconds or less under the safety conditions described above. This makes it possible to precisely adapt the quantity of extinguishing agent required to the storage space available for the cylinders.

Every system is optimized for worst-case conditions, and all components are certified to ensure the strictest performance standards. These components are essential for the storage, detection, release, and timely discharge of the extinguishing agent.

The complete system comprises the following components:

• Storage cylinder group and storage cylinder group frame
• Nitrogen driving device and nitrogen driving device frame
• Cylinder valve, liquid flow check valve, and air flow check valve
• Electromagnetic starter
• Gas conveying pipeline, collecting pipe, and pipe
• Choice valve, three links, reducer tee, and reducing elbow
• Flange, safety valve, and pressure transmitter
• Nozzle and chemicals
• Fire detector and fire controller
• Sound and light alarm, alarm bell, and gas light
• Emergency start / stop button

The following are typical hazards protected by IG-100 nitrogen systems:

• Computer rooms
• Subfloors
• Tape storage
• Telecommunications and switchgear rooms
• Vaults
• Process equipment
• All normally occupied or unoccupied areas where electronic equipment is either very sensitive or irreplaceable

• Compared with traditional 15 MPa systems, the number of fire extinguishing agent cylinders can be reduced by 25%–50%.
• The building area required between cylinders is effectively reduced, improving the overall occupation and utilization rate of the building.
• Constant 6 MPa low-pressure release reduces the cost of pipelines and pipe fittings.
• The constant release pressure of 6 MPa provides more lasting and effective pressure, with a transmission distance of up to 200 meters.
• Low-pressure release across the whole system has less impact on on-site personnel, equipment, and building structure, making it safer.
• The external constant-pressure reliever only bears pressure while the system is spraying, making disassembly and maintenance convenient and effectively reducing the system failure rate.
• After spraying, no parts need to be replaced — simple disassembly and secondary filling allow the system to be quickly put back into operation.
• The opening area of the pressure-relief device is reduced, directly lowering the input cost of the pressure-relief device, while the safety buckle is installed and arranged more simply.
• The IG-100 nitrogen fire extinguishing system can be widely used for rapid response to fire, protecting on-site staff, handling sudden fires, safeguarding important places sensitive to chemical reactions, and effectively protecting the safety of personnel and property.
