Dry Powder Wheeled Fire Extinguisher

Dry powder wheeled fire extinguisher is an efficient and mobile fire fighting device.

Dry powder trolley fire extinguisher can quickly put out initial fires and prevent the fire from spreading, ensuring safety and efficiency.

The multi-purpose dry chemical extinguishers are crafted from HP245 material.

The normal used specification is: 25kg dry powder trolley fire extinguisher and 50kg dry powder wheeled fire extinguisher.

Dry powder trolley fire extinguisher is suitable for extinguishing different types of fires.
If the extinguishing agent filled in the dry powder trolley is 40% ABC (EN615), then it is suitable for extinguishing Class A, Class B, and Class C fires.

1.Class A Fire: Fires involving solid materials such as wood, paper, cloth, and plastic.
2.Class B Fire: Fires involving flammable liquids such as oil, grease, and coal.
3.Class C Fire: Fires involving flammable gases such as natural gas and liquefied gas.

● The features of the EN-615 dry powder extinguishing agent:
1.The EN-615 dry powder extinguishing agent uses ammonium dihydrogen phosphate and ammonium sulfate as its basic extinguishing material.
2.The fire extinguishing agent is characterized by fast extinguishing speed, high efficiency, good insulation properties, and long storage life.
3.Due to its excellent insulating properties, dry powder extinguishers can be used to extinguish fires on electrical equipment.

Dry powder trolley extinguishers are commonly used in places like oil depots, warehouses, refineries, transformer rooms, and petrochemical enterprises.

The fire suppression mechanism of dry powder wheeled extinguishers relies on a combination of suffocation, cooling, and interruption of the combustion chain reaction, enabling swift and effective fire control.

1.Suffocation effect:
When used, the dry powder extinguishing agent rapidly forms a powdered covering layer that coats the surface of the combustible material, isolating the flame from the air and thus achieving the effect of suffocating the fire.

2.Cooling effect:
The inorganic salts and other components in the dry powder extinguishing agent decompose and absorb heat under the high temperature of the flame, reducing the temperature of the flame.
Furthermore, the powdered material itself exerts a cooling effect on the flame, causing the temperature of the combustible material to drop below the ignition point, thereby extinguishing the flame.

3.Suppression of combustion chain reaction:
The chemical components such as inorganic salts in the dry powder extinguishing agent can chemically inhibit and co-catalyze the free radicals or reactive groups in the combustible material, interrupting the chain reaction of combustion and preventing the continued propagation and expansion of the flame.
 

1.Please store the fire extinguisher in a dry and ventilated area, avoiding moisture or direct sunlight.
2.Regular inspection and maintenance are essential to maintain the extinguisher in optimal working condition.
3.The pressure gauge should be checked regularly.
If the pointer falls from the green zone and enters the red zone, the fire extinguisher should be sent to a professional institution for inspection and repair.
4.Please follow proper operational procedures and safety regulations to ensure effectiveness and safety when using the wheeled dry powder fire extinguisher.
