25 Litre Lith-Ex Extinguisher - Wheeled

As these batteries become more prevalent in energy storage, manufacturing, and transportation, so does the danger of thermal runaway - a chain reaction that can lead to intense fires that are difficult to control. 

To combat this risk, the Lith-Ex extinguisher utilises Aqueous Vermiculite Dispersion (AVD), an innovative extinguishing agent that cools the fire, encapsulates the burning material, and prevents reignition. This rapid suppression method is crucial for high-risk areas where battery-related fires can escalate quickly.

Fully CE-marked and MED approved, this extinguisher is an essential safety measure for factories, energy storage facilities, and battery charging stations. Its portable trolley design allows for fast, easy deployment, ensuring that fire hazards are managed swiftly and effectively. 

What Makes Lithium-Ion Batteries a Fire Hazard?

Lithium-ion batteries are found in everything from consumer electronics to large-scale energy storage systems, but their high energy density also makes them a fire risk. When damaged, overcharged, or exposed to extreme conditions, they can experience thermal runaway - a dangerous chain reaction that generates intense heat, flammable gases, and toxic smoke. These fires spread rapidly, are difficult to extinguish, and can reignite if not properly contained. Lithium-ion battery fire extinguishers are a solution to combatting these fires as conventional extinguishers are often ineffective. 

How Does AVD Extinguish Lithium-Ion Battery Fires?

Aqueous Vermiculite Dispersion (AVD) is a next-generation extinguishing agent, designed specifically for lithium-ion battery fires. It consists of a water-based suspension (17% vermiculite, 83% water) with a viscous consistency, allowing it to adhere to surfaces and form an effective fire barrier. 

• Cooling effect - The water component instantly reduces heat, stopping thermal runaway
• Encapsulation and Fire Containment - As the water evaporates, vermiculite forms a protective film, cutting off oxygen and heat transfer to prevent re-ignition.
• Non-Conductive and Safe - Unlike traditional extinguishing agents, AVD is electrically insulating, making it safe for fires involving live battery systems.

By providing fast cooling, fire containment, and electrical insulation, AVD ensures efficient, long-lasting suppression of lithium-ion battery fires - delivering nearly twice the effectiveness of water-based extinguishers.
