The internal cylinder dry powder fire extinguisher utilizes a separate, internal high-pressure gas cylinder to generate driving pressure at the moment of activation. Its unique atmospheric pressure storage method offers significant advantages, including increased reliability, longer lifespan, and easier maintenance, making it a top choice for industrial, transportation, and automated firefighting systems, where performance requirements are critical.

Advantages of 6KG Inside Gas Cartridge Dry Powder

High Reliability
This is its greatest advantage. Because the main tank is normally unpressurized, it avoids leaks caused by corrosion, weld fatigue, or seal deterioration that can occur due to long-term pressure. Even after years of storage, as long as the internal cylinder is intact, it will provide sufficient power upon activation.
Stable Performance
The pressure in the internal cylinder is sealed and constant, eliminating the risk of failure due to an inaccurate pressure gauge or slow leaks, as with conventional stored-pressure fire extinguishers. It ensures sufficient and stable power every time it is discharged.


Easy Maintenance
Because the main tank is unpressurized, periodic hydrostatic tests (e.g., every five years) only require testing of the internal cylinder, making operation simpler and safer.
Applicable to special scenarios
Especially suitable as the on-site startup part of the automatic fire extinguishing system, or installed in vehicles, ships and other environments with vibration and requiring long-term reliable backup.

Type of 6KG Inside Gas Cartridge Dry Powder
Manual Activation: A manual activation button is required. The extinguisher usually has a clearly visible push-button or push-button.
Automatic activation: The activation mechanism is connected to a temperature-sensing element (such as a glass bulb). When the ambient temperature in the protected area rises sharply and reaches a predetermined value (such as 68°C or 93°C), the glass bulb ruptures, releasing the activation mechanism and triggering the internal gas cylinder valve.
Electrical activation: The activation mechanism is a squib or solenoid valve. When the automatic fire alarm system confirms a fire, it sends a starting current to the fire extinguisher. The force generated by the squib's explosion pushes open the gas cylinder valve, or the solenoid valve activates, releasing the propellant gas.
Combined activation (manual + automatic): This type combines two or more activation methods, most commonly "manual + automatic" or "manual + electric." This provides greater reliability. For example, even if the automatic function fails, manual activation is still possible.
Applications of 6KG Inside Gas Cartridge Dry Powder
Automatic fire extinguishing systems
Many dry powder automatic fire extinguishing systems utilize a built-in gas cylinder design, automatically triggered by an electrical signal or temperature sensor.
Transportation
Automatic fire extinguishing systems in the engine compartments of buses, construction vehicles, and ships.
Industrial sites
Oil fields, power plants, chemical equipment, and other critical fire protection areas requiring extremely high reliability.
Critical facilities
Localized fire extinguishing systems in computer rooms and archives (although gas is more commonly used, dry powder is also an option).
Components of 6KG Inside Gas Cartridge Dry Powder

Fire extinguisher body
The main container for the dry powder, normally unpressurized.

Internal high-pressure gas cylinder
The core component, a small steel cylinder filled with high-pressure propellant gas (CO₂ or N₂).

Actuation mechanism
Can be manual (a button that needs to be pressed) or automatic (activated by a temperature-sensitive glass bulb or electric squib).

Spray gun and nozzle
The outlet for the dry powder spray.
Operating Principle
•Standby Mode: The internal gas cylinder valve is tightly closed, and the main tank is pressure-free.
•Triggering Mode
Manual Mode: The operator firmly presses the start button, causing a mechanical mechanism to puncture or open the seal of the internal gas cylinder.
Automatic Mode: When the ambient temperature reaches the temperature sensor's trigger value (e.g., 68°C), the glass bulb ruptures, triggering the mechanism to open the gas cylinder.
•Gas Release: High-pressure gas rapidly ejects from the internal gas cylinder, filling the main tank and instantly building up significant pressure.
•Fire Extinguishing Agent Injection: High-pressure gas compresses the dry powder, causing it to be ejected at high speed from the spray gun through a siphon tube toward the fire source.
Daily Inspections
Check whether the fire extinguisher is placed in its designated location and has not been moved or used for other purposes. Check for obstructions or debris that might interfere with access or automatic activation.
Check whether the ambient temperature at the installation location is within the normal range (avoid extremely high or low temperatures).
Nameplate: Check for clarity and integrity, and whether the information marked (such as agent type, filling volume, and operating temperature) is clear.
•Safety Device:
Manual Model: Check the safety pin and seal for integrity and any difficulty in insertion or removal.
Automatic Model: Focus on inspecting the temperature-sensing glass bulb for cracks, grease, or paint. This is crucial for automatic function!
Visible Components: Check the nozzle and gun for blockage, cracks, aging, or corrosion.
Pressure Indicator (Dial): If equipped with a pressure gauge, the needle must be in the green zone (or the designed pressure range). This is the only window for monitoring the internal gas cylinder pressure. If the needle is in the red zone, the internal gas cylinder pressure is insufficient and must be reported immediately.
Overall appearance: Check the fire extinguisher tank for signs of severe rust, deformation, bumps, dents or leakage.
