This high-quality fire extinguishing granulate is the ideal solution for the safe storage and the clean, efficient extinguishing of Lithium-Polymer (LiPo) and Lithium-Ion batteries. Whether in workshops, RC applications, e-bike service centers, or battery storage areas – with Extover®, you are perfectly equipped to handle critical lithium and metal fires.
How Extover® Works:
The expanded glass granulate is gently poured onto the fire source, encapsulating the burning material and cutting off oxygen supply. At extremely high temperatures, the material melts, spreading over the surface like a glass seal. Upon cooling, it solidifies into a crust, creating an airtight barrier that prevents re-ignition.
Tested Fire Performance:
The extinguishing effectiveness for metal fires has been tested and verified by MPA Dresden using sodium and magnesium fire trials.
Application Areas & Fire Classes:
Extover® is suitable for Class D fires (metal fires) and lithium battery fires (LiPo, Li-Ion). It helps control difficult fire loads such as burning batteries, metals, or reactive materials without causing secondary damage.
Application – In 3 Steps:
- Secure the area: Clear surroundings, maintain safe distance, wear PPE.
- Apply gently: Pour the granulate softly and generously over the fire source.
- Cover completely: Ensure a layer of 10–30 cm above the fire. Allow the area to cool, then dispose of contaminated material properly.
Key Benefits:
- Forms a protective, airtight layer through melting and solidification
- Oxygen displacement for effective suffocation of the fire
- Environmentally friendly, 100% inorganic, inert, non-reactive
- Long-lasting, maintenance-free, non-perishable
- Lightweight and low thermal conductivity
- Excellent liquid absorption, acid and alkali resistant
- Bacteria- and germ-free, sound absorbing
- Easy to integrate into existing safety concepts
Typical Applications:
- Safe storage of LiPo/Li-Ion batteries (e.g., in battery safes, transport boxes)
- Fire suppression in case of thermal runaway or metal fire
- Workshops, RC model building, e-bike/e-scooter service, test & charging stations, shipping preparation
Why Extover® Instead of Water, Sand, or ABC Powder?
- Clean and efficient: No fine dust or contamination of electronics and surroundings
- Sustainable: Inorganic, inert, and non-toxic
- Reliable: Melting/crusting effect prevents re-ignition effectively
Recommended Layer Thickness:
Apply a 10–30 cm layer above the fire source, depending on the size and type of the burning object.
FAQ:
- How long does Extover® last? The granulate is non-aging and non-perishable – ideal for long-term storage.
- Does it cause secondary damage? Extover® extinguishes fires cleanly and avoids contamination typical of powder extinguishers.
- Which fires can it handle? Suitable for Class D (metal) and lithium battery fires (LiPo, Li-Ion).
Safety Information:
Always wear suitable PPE during firefighting, avoid inhaling vapors, and ventilate the area afterward. Dispose of contaminated materials in accordance with local regulations.
