Portable Water Mist Firefighting Unit (Gasoline Engine–Driven)

1. Product Overview

The wheeled water mist fire extinguishing unit is a mobile fire suppression device that integrates high extinguishing efficiency, operational flexibility, environmental safety, and system reliability into a single platform.

The unit utilizes high-pressure water mist technology, atomizing water into ultrafine droplets that suppress fire through cooling, oxygen displacement, radiant heat attenuation, and smoke scrubbing, achieving rapid control and extinguishment of early-stage fires.

Because it does not rely on fixed piping networks and is not constrained by architectural layout, this equipment is ideally suited for mobile emergency operations in airports, industrial facilities, petrochemical plants, transportation hubs, warehouses, and energy infrastructures.

2. Key Advantages

Personnel Safety and Operator-Friendly Performance

• Uses water only, producing no toxic chemicals and no harmful by-products.

• The discharge pressure is moderate, and the ultrafine droplets reduce the risk of secondary injury caused by high-velocity streams.

• Provides significant smoke suppression, improving visibility and enhancing firefighter safety.

Environmentally Sustainable

• The extinguishing medium is pure water, with no greenhouse gas emissions.

• Extremely low water consumption: compared with conventional hose streams, water usage is reduced by 70–90%.

Minimal Water Damage

• Ultrafine droplets evaporate rapidly, preventing large-area water accumulation.

• Suitable for water-sensitive environments such as laboratories, communication rooms, museums, archives, and electrical equipment areas.

Rapid, Efficient, and Applicable to Multiple Fire Classes

The wheeled water mist unit demonstrates excellent performance on the following fire classes:

• Class A: Solid combustibles (paper, wood, furniture, textiles)

• Class B: Flammable liquids (fuels, solvents)

• Class C: Energized electrical equipment fires (within safe operating distance)

• Class K / F: Cooking oil and grease fires (rapid cooling and reflash prevention)

The system rapidly forms a water mist curtain during initial fire stages, greatly reducing thermal radiation and preventing fire spread.

Highly Mobile and Rapid Response

• Wheeled chassis design enables single-person or two-person operation, allowing rapid arrival at the fire scene.

• No external power supply is required; the unit is ready for immediate use once brought to the incident location.

• Modular construction allows fast deployment, easy maintenance, and simplified logistics.

3. Operating Principle

The unit delivers water to the nozzle through a high-pressure pump, where it is atomized into ultrafine droplets These droplets form a uniform water mist field within the fire area and suppress the fire through multiple mechanisms:

• Instantaneous Cooling: The droplets absorb large amounts of heat during vaporization, rapidly reducing flame temperature.

• Oxygen Displacement: The expansion of water vapor locally reduces the oxygen concentration, inhibiting the combustion reaction.

• Radiant Heat Attenuation: The mist plume forms a particle barrier that significantly reduces radiant heat, protecting personnel and equipment.

• Smoke Suppression and Air Cleaning: Water mist captures smoke particulates, improves visibility, and aids in safe evacuation and firefighting operations.

This fire suppression process is highly efficient, inherently safe, and produces virtually no secondary damage, making the system an ideal emergency response device for critical facilities.
