Extover® is suitable for class D fire loads and has been designed and tested for metal and lithium battery fires.

Extinguishing effects

Extover® is multipurpose and can be used bulk, in mobile units or in class D metall fire extinguishers. The granules cause no damage like water or powder and are totally safe. The primary extinguishing effect is based on suffocation and isolation of the source of fire.
