9kg Superfine Powder Fire Extinguishing Devices for Supermarket

Pressure storage ultrafine dry powder fire extinguishing device is a kind of efficient and environmentally friendly fire extinguishing equipment, with the following significant benefits:

• Rapid fire extinguishing. Ultra-fine dry powder (particle size usually ≤ 20μm) has a great specific surface area, can quickly adsorb free radicals in the flame, interrupt the combustion chain reaction, and extinguish the fire 4-6 times faster than ordinary dry powder.
• Fully flooded application. It can be suspended in the air for extended periods to achieve total flooding and cover concealed fires.
• Non-toxic and harmless. The main components of this product are harmless to the human body and the environment, and are suitable for use in manned places.
• Không bị ăn mòn. It has very low corrosiveness to electronic equipment, metals, vân vân., reducing secondary damage.
• Wide applicability. It applies to multiple types of fires, can extinguish Class A (chất rắn), class B (chất lỏng), Lớp C (khí ga), lớp E (điện) fires, especially suitable for flammable and explosive places (e.g., oil depots, nhà máy hóa chất, trạm biến áp).
• High stability. The pressure storage structure ensures stable spray pressure and even distribution of the extinguishing agent.
• Intelligent control and linkage. It can be started automatically, bằng tay, and mechanically in case of an emergency. It can be matched with fire detectors to achieve unattended automatic fire extinguishing.
• Installation Flexibility. Kích thước nhỏ, can be wall-mounted, suspended, or embedded installation, can save space.
• Simple maintenance. Only regular pressure checks are required daily, resulting in low maintenance costs.
• Technical certification. This product is CE certified to ensure reliability.

This product can be used for both full flooding and localised applications.

Typical applications of this product are:

• phòng phân phối điện.
• Data centres.
• Lithium battery compartment.
• Ship's engine room.
• Subways and tunnels.
• Chemical plants.
• Trạm biến áp.
• Phòng máy chủ.
• Phòng máy tính.
• Oil depots.
• Heritage Archives.
• Historical Museums.
• Department store.
• Generator houses.
• Cable shafts.
• Warehouses and Storehouses.
• production plants.

This product is designed without a pipe network, saving space, and is suitable for shopping mall or supermarket renovation projects.

When using an ultrafine dry powder fire extinguishing device, the following should be noted to ensure its effectiveness and safety:

1. Biện pháp phòng ngừa khi lắp đặt

• Reasonable arrangement. Angle the extinguishing device when installing it to achieve the best fire extinguishing effect.
• Environmental Adaptation. Avoid installation in high temperatures (>50° C), high humidity, or corrosive environments to prevent device failure.
• Outdoor installation requires a rain cover to prevent water ingress.
• Linkage control. When linking with the fire alarm system, it is necessary to test the reliability of signal transmission to avoid false activation or delay.

2. Precautions for use

• Applicable fire types. This product is suitable for A (chất rắn), B (chất lỏng), C (khí ga), và E (điện) class fires, but does not apply to class D metal fires (such as magnesium, natri, vân vân.).
• Electrical fires require disconnection (use with caution at ≥5kV).
• Personnel security. Spraying generates a large amount of dust, which may affect visibility and breathing, and personnel need to be evacuated quickly.
• Protective measures. Avoid direct inhalation of dry powder and wear a dust mask if necessary.
• Spray aftertreatment. After extinguishing the fire, it is necessary to ventilate and clean up the residual dry powder (especially for precision equipment, circuit boards, vân vân.).
• Check that the equipment is not damaged and that dry powder may have entered mechanical parts (e.g., servers, motors).

3. Maintenance and Inspection

• Regular inspections. Regular annual and monthly inspections, checking pressure gauges, and checking the casing for breakage.
• Replacement & Bảo trì. Dry powder shelf life is usually 5~10 years, and over this period needs to be replaced. When the nozzle is clogged or corroded, clean or replace it in time.

4. Các biện pháp phòng ngừa khác

• Do not disassemble or change the structure of the unit at will (e.g., extend the piping, change the nozzle model).
• Avoid false triggering. Avoid high-temperature work or welding in the protection zone to prevent false activation of the thermal element.

When your fire suppression unit does not activate, check the power supply (electrically controlled), check the fuse pins, or contact an overhaul professional.

When the dry powder in a fire extinguishing device clumps, you need to replace it with new dry powder and check that the storage environment is dry or not.
