The 50-litre Lith-Ex extinguisher - wheeled is a powerful and innovative solution designed to combat the increasing risks associated with lithium-ion battery fires. Featuring an advanced Aqueous Vermiculite Dispersion (AVD) agent, this larger capacity extinguisher provides superior fire suppression capabilities, making it an ideal choice for high-risk industrial environments, battery storage facilities, and manufacturing plants. With full CE marking and MED approval, it meets the highest industry safety and performance standards.
Engineered for tackling larger lithium-ion battery fires, the Firechief 50L Lith-Ex fire trolley extinguisher offers an extended firefighting capacity with a robust and easily manoeuvrable trolley design. This ensures rapid deployment in critical emergencies where quick response is essential. Once discharged, the AVD mist works efficiently to cool the fire source, halt thermal runaway, and prevent further escalation.
Upon application, AVD forms a protective vermiculite barrier around the burning material, encapsulating the fuel source and preventing re-ignition. Its non-toxic and environmentally friendly properties make it a safe and sustainable choice for use in enclosed and sensitive environments. Whether used in warehouses, energy storage facilities, or industrial factories, this extinguisher delivers unparalleled performance and peace of mind in the fight against lithium-ion battery fires.
AVD and Its Effectiveness
Aqueous Vermiculite Dispersion (AVD) is the key component of the Firechief Lith-Ex extinguisher range, providing a highly effective suppression solution for lithium-ion battery fires. This specialised agent consists of vermiculate platelets suspended in water (17% vermiculite, 83% water), giving it a smooth viscous consistency comparable to double cream. It is a mineral mined all over the world, is non-flammable and has excellent thermal insulation properties.
Key benefits of AVD:
Rapid Cooling - The water component immediately reduces the temperature of the burning battery, stopping thermal runaway in its early stages.
Encapsulation - As the water evaporates, vermiculite forms a protective layer over the battery, acting as a thermal oxygen, and electrical barrier that prevents reignition.
Non-Conductive - The vermiculite barrier provides electrical insulation, ensuring safe suppression even in environments with live electrical components.
With nearly twice the effectiveness of water in combating lithium-ion battery fires, AVD offers a reliable and advanced suppression method without the risks associated with conductive or chemically reactive extinguishing agents. The Firechief 50L Lith-Ex extinguisher harnesses this technology to provide exceptional fire protection, safeguarding assets, facilities, and personnel against the dangers of battery fires.
Why Are Lithium-Ion Batteries a Fire Hazard?
Lithium-ion batteries power a wide range of devices, from consumer electronics to industrial-scale energy storage systems. While efficient, these batteries pose a significant fire risk when damaged, overcharged, or exposed to extreme conditions. A compromised battery can undergo thermal runaway, a dangerous self-sustaining reaction that produces excessive heat, flammable gases, and toxic smoke.
Once ignited, lithium-ion battery fires are difficult to extinguish using traditional methods, as they can reignite even after initial suppression. This makes it essential to have specialised lithium-ion battery fire extinguishers, which are designed to stop the chemical reaction effectively and prevent fire propagation.
