Using lava stones in cooling and freezing facilitates a quantum leap in energy efficiency

Liebherr-Hausgeräte GmbH is revolutionising technology in its fridges and freezers. Liebherr is the only manufacturer in the world to use a vacuum in conjunction with finely ground lava stone, the raw material perlite, to insulate its appliances. The first vacuum perlite models, named BluRoX, will be on the market as early as January 2023. For the very first time, it is possible to produce freezers with the energy efficiency class “A” and “B” in accordance with EU legislation thanks to the innovative technology.
