The 25-litre Lith-Ex extinguisher - wheeled is a cutting-edge fire safety solution, designed to tackle the growing threat of lithium-ion battery fires. Featuring the revolutionary Aqueous Vermiculite Dispersion (AVD) agent, it delivers fast effective suppression, making it an indispensable tool for industrial environments, battery storage areas, and facilities using lithium-ion batteries.


Designed for large lithium-ion battery fires, the Lith-Ex extinguisher provides powerful and precise performance in high-risk environments. Fully CE marked and MED approved, this extinguisher is built to the highest safety standards. Its mobile trolley design allows for quick and easy deployment, ensuring responders can act immediately.


The AVD mist not only cools the fire source but also halts thermal runaway, stopping it before it spreads. The solution creates a vermiculite shield, encapsulating the burning material and blocking oxygen, heat, and electrical conductivity. This prevents reignition and fire propagation, offering long-lasting suppression. AVD is non-toxic, environmentally safe, and highly effective in confined spaces, making it ideal for battering charging stations and storage facilities. 


What Makes Lithium-Ion Batteries a Fire Hazard?

Lithium-ion batteries power everything from smartphones to industrial energy storage systems, offering efficiency and reliability. However, under stress, damage, or fault conditions, these batteries can become dangerously unstable. When failure occurs, it can lead to thermal runaway - a self-sustaining chemical reaction that generates intense heat, flammable gases and toxic smoke. These fires spread rapidly and can reignite even after initial suppression, making them particularly challenging to extinguish, which is why a specific lithium-ion battery fire extinguisher is essential.


How Does AVD Extinguish Lithium-Ion Battery Fires?

The Firechief Lith-Ex fire trolley extinguisher features Aqueous Vermiculite Dispersion (AVD), a next-generation extinguishing agent specifically formulated for lithium-ion battery fires. AVD is a stable suspension of vermiculite platelets in water (17% vermiculite / 83% water) with a viscosity similar to double cream (3000 cPs).


Key benefits of AVD include:

  • Cooling Power - The water component instantly reduces heat, stopping thermal runaway before it spreads.
  • Encapsulation - As the water evaporates, vermiculite forms a protective barrier around the fire source, blocking oxygen, heat, and electrical conductivity to prevent re-ignition. 
  • Non-Conductive Safety - The vermiculite coating acts as an electrical insulator, making it safe for fires involving live electrical equipment.

Thanks to its unique suppression method, AVD is nearly twice as effective as water, ensuring faster, safer, and more reliable fire suppression for lithium-ion battery incidents.
