High-pressure IG100 Gas Fire Suppression System Piping Accessories for Automatic

IG100 uses 100% pressurized nitrogen — which makes up 78% of the atmosphere — as the extinguishing agent. Its ozone depletion potential (ODP) and global warming potential (GWP) are both zero, and its atmospheric retention time is zero, with no adverse effects on the environment. The system fully integrates the design concept of the modern fire-extinguishing system, giving the product both environmental protection and efficient fire-fighting performance.

IG100 characteristics: protects the ecological environment, is safe and hygienic, does not interfere with vision, leaves no stains from the extinguishing agent, and delivers a durable fire-fighting effect. Nitrogen can be separated from the air and produced from a wide range of sources at low cost.

Combined with the extinguishing device and electronic accessories, the whole system can be actuated automatically. It monitors the situation of the protected region through detectors and can then start the extinguishing device through a solenoid actuator automatically, achieving full automation. This avoids the risk of a fire going unnoticed when no one is present, and it also saves the cost of employing personnel to supervise the protected area.

Management of multiple zones is also under the safe control of the whole system. One system can protect multiple zones through distributing valves, allowing the system to alternate between different protected zones. Agent is discharged only into the zone where the fire occurs, making fire suppression highly efficient in a short time. Note that a small room should be reserved as storage space for the whole system.

Structure: The IG541 mixed gas fire extinguishing cylinder group consists of the fire extinguishing agent and storage containers, container valves, safety relief devices, pressure gauges, and related components.

2.3 Purpose

The container valve is installed on the fire extinguishing agent storage cylinder to seal the extinguishing agent inside. During a fire, the valve is typically opened by actuating gas to release the extinguishing agent for fire suppression.

2.4 Usage and Maintenance Instructions

• 2.4.1 The container valve features two operating modes: gas activation and manual mechanical operation. Gas activation involves the activation gas driving the piston rod within the actuator cylinder to puncture the working diaphragm of the container valve, thereby opening the valve. Manual mechanical operation requires manual operation of the container valve handle for valve opening; this mode is employed in emergency situations.
• 2.4.2 The container valve is equipped with a safety diaphragm (with an explosion pressure of 23 MPa) to prevent excessive pressure inside the fire extinguishing agent cylinder by releasing pressure, thereby ensuring cylinder safety. Under normal conditions, the safety diaphragm remains inactive; it may only rupture under abnormal circumstances such as excessively high filling pressure or elevated ambient temperature. If the safety diaphragm ruptures and the cylinder pressure is released, the diaphragm must be replaced immediately, a seal integrity test conducted, and the cylinder refilled with fire extinguishing agent. When replacing the diaphragm, only diaphragms provided by our company that are identical in model and specifications to the original one and have passed testing must be used; arbitrary substitution is prohibited.
• 2.4.3 During the filling of fire extinguishing agent, the filling port (as shown in the figure above) should be connected to the gas source; simply loosen the securing screw to proceed with filling. After completion, the securing screw must be tightened before removing the filling connector. Fire extinguishing agent filling shall be performed by qualified professionals.
• 2.4.4 After the container valve is operated, it must be manually reset and inspected for any abnormalities before resuming use.

3.1 Purpose

The gas actuator is mounted on the container to activate its valve. During a fire, the controller issues a fire suppression command, activating the gas cylinder bank corresponding to the selection valve. This bank releases the activation gas, which opens the respective selection valve. The activation gas then flows through a gas check valve into the actuator pipeline, driving the internal blade to puncture the working diaphragm in the container valve, thereby opening the valve. The valve subsequently releases the fire extinguishing agent to suppress the fire.

During manual activation, remove the safety pin, press the manual handle to puncture the working diaphragm in the container valve, open the valve, and release the fire extinguishing agent to extinguish the fire.

Model, structural diagram and main performance parameters:

Structure: Consists of an air cylinder and an electromagnetic starting valve.

Working Principle: The gas cylinder is a steel pressure vessel filled with high-pressure nitrogen. In the event of a fire alarm, the fire alarm controller outputs a DC-24V current, which activates the electromagnet to open the starting valve, releasing the nitrogen from the cylinder. The released nitrogen then flows through the drive pipeline, opening the container valve. During emergencies, the manual button safety pin can also be removed, allowing immediate activation of the starting valve upon button press.

Structure: The manual/electromagnetic valve consists of the main valve body, connection seat, electromagnet, actuator rod, spring, manual button, and manual safety pin.

Working Principle: The manual/electromagnetic valve is installed on the start-up bottle assembly or container valve. When a fire alarm occurs in the protected area, the fire alarm controller outputs a DC 24V current, activating the electromagnet to push the actuator rod and open the container valve or start-up valve. In emergencies, the manual safety pin can be immediately removed, and the button pressed to open the container or start-up valve.
