Stop thermal
runaway
The UK-engineered extinguisher built for lithium-ion battery fires. Aqueous Vermiculite Dispersion cools each cell and coats it in a mineral barrier, stopping the chain reaction and re-ignition.
Engineered in the UK for
lithium-ion battery fires.
AVD Fire pioneered Aqueous Vermiculite Dispersion, a patented, water-based agent that tackles battery fires at a cellular level. From 500ml aerosols to 50L trolley units, every extinguisher is designed, developed and manufactured in Britain.
Lith-Ex by AVD
The lithium battery extinguisher.
Discharge creates a fine vermiculite mist that cools the fire and coats every cell in a protective mineral barrier, stopping heat spread and re-ignition. Safe on live electrical equipment, non-toxic and REACH compliant.
Interrupts thermal runaway.
Cools the fire
A fine mist drops the temperature of burning cells fast.
Coats each cell
A mineral vermiculite barrier seals cells from heat.
Stops re-ignition
Breaks the thermal-runaway chain reaction for good.
Non-toxic
Naturally occurring vermiculite. PFAS-free, REACH compliant.
