Mobile Foam Trolley

The Mobile Foam Trolley features an FRP main body, aluminum alloy injector, and SS304/stainless steel nozzles with 2×20m hoses. Ideal for Class B fires in tank cofferdams and vehicle incidents, it uses water-pressure-driven 3%-6% foam mixing, offers IP67/IP69K protection, and operates at 0.7-1.4MPa.

Specifications

1. Main body material: FRP;
2. Injector: Aluminum alloy;
3. Foam nozzle: SS304 stainless steel, aluminum alloy;
4. Fire hose: 20 meters × 2 rolls;
5. Connectors: STORZ, NH, John Morris, GOST, Machino, etc.
6. Surface treatment: spray painting.

Application:

1. Fight Class B liquid fires (fuel, solvents, etc.), especially suitable for tank cofferdam leakage, small hazardous chemical accidents and vehicle fires.
2. As a supplement to fixed fire protection systems or temporary emergency equipment, covering the blind spots of fixed devices.

Working principle:

1. Mixing: The water pump draws water from the water source (fire hydrant/water tank), and sucks the foam stock liquid through the proportion mixer according to the preset ratio (such as 3%/6%) to form a mixed liquid.
2. Foaming: The mixed liquid is transported to the foam gun/cannon through a hose, mixed with air and expanded to form fire extinguishing foam.
3. Covering fire extinguishing: Foam covers the surface of the burning liquid, extinguishing the fire by isolating oxygen, cooling and suppressing steam.

Features:

1. High corrosion resistance: GFRP material resists chemical and salt spray corrosion, and has a longer life than traditional metal shells.
2. Strong mobility: The cart-type design realizes "pull and use" and has a very fast response speed.
3. Environmental adaptability: The protection level reaches IP67/IP69K, is resistant to vibration and shock, and is suitable for a temperature range of -40°C to 85°C.
4. Easy to operate: No external power supply is required, it relies on water pressure drive, and fire extinguishing can be completed by manual control.
