Extover®

Extover is an innovative fire protection and extinguishing granulate made from 100 percent recycled glass, engineered specifically for safe handling of lithium ion and lithium polymer batteries. The mineral granulate absorbs energy from a battery fire, reduces flames, dissipates heat and helps to minimize flying sparks. This makes storage, transport and use of lithium batteries significantly safer.

SmoliTec Allgäu supplies Extover in various packaging formats, from compact Extover cushions for safety boxes and enclosures to larger Extover buckets for workshops, industrial environments and logistics. Combined with suitable safety boxes or fire protection systems, Extover becomes a powerful component in a complete safety concept for RC applications, e bike batteries, energy storage systems, workshops, labs and professional users.
