The 25-litre Lith-Ex extinguisher - wheeled is a revolutionary firefighting tool designed to tackle the growing hazard of lithium-ion battery fires. Powered by a revolutionary Aqueous Vermiculite Dispersion (AVD) extinguishing agent, it provides rapid and effective suppression, making it an essential choice for industrial environments, energy storage facilities, and any location where lithium-ion batteries are in use. Fully CE marked and MED approved this extinguisher meets the highest safety and performance standards.

Designed for use on larger lithium-ion battery fires, the Lith-Ex extinguisher offers powerful, targeted performance in high-risk environments. Its portable design makes it easy to manoeuvre, ensuring fast deployment in emergencies. Once applied, the AVD mist works quickly to cool the fire source, reducing heat and stopping the threat of thermal runaway.

By forming a protective vermiculite barrier, the extinguisher encapsulates the fuel source, preventing reignition and further fire propagation. AVD is also non-toxic and environmentally friendly, making it a safe and sustainable choice. Its effectiveness in confined spaces makes it particularly well suited for battery storage and charging areas, ensuring that fires are controlled before they can escalate.

Whether protecting factories, energy storage sites, or industrial facilities, the Firechief 25L Lith-Ex fire trolley extinguisher offers peace of mind and powerful fire suppression when it matters most. 


Why are Lithium-Ion Batteries a Fire Risk?

Lithium-ion batteries, found in everything from mobile devices to industrial energy storage systems, are compact and efficient energy sources. However, under stress - such as damage, overcharging, or manufacturing defects - they can become volatile. A fault can lead to thermal runaway, a chemical chain reaction that generates extreme heat, flammable gases, and toxic smoke, often resulting in fast-spreading fires. Once ignited, these fires are notoriously difficult to extinguish and can reignite if not properly managed. This type of complex fire requires a specific type of lithium-ion battery fire extinguisher.


What is AVD and How Does it Work?

The Firechief Lith-Ex extinguisher uses Aqueous Vermiculite Dispersion (AVD), a cutting-edge agent specifically formulated to extinguish lithium-ion battery fires. AVD is a stable suspension of vermiculite platelets in water (17% Vermiculite / 83% water) and has a viscosity of 3000 cPs - feels a bit like double cream. There are several benefits to AVD:

  • Cooling - The water content immediately reduces heat, stopping thermal runaway in its tracks.

  • Encapsulation - As the water evaporates, vermiculite forms a protective film over the fuel source. This layer acts as a thermal, oxygen, and electrical barrier, preventing reignition and the spread of fire. 

  • Non-conductive - The vermiculite film is electrically insulating, ensuring the safe suppression of fires involving live electrical components. 

This combination of features makes AVD nearly twice as effective as water in extinguishing lithium-ion battery fires, without the risks associated with conductive or reactive extinguishing agents.
