BluRoX: Vacuum insulation with perlite

BluRoX – our vacuum perlite technology innovation

Welcome to the future of cooling and freezing. BluRoX, our groundbreaking innovation, combines finely ground volcanic rock, perlite, with vacuum insulation to deliver unmatched energy efficiency in a compact design. Unlike traditional insulation methods, BluRoX's unique combination ensures optimal thermal conductivity, significantly reducing energy consumption, setting a new standard in sustainable refrigeration.

Designed with circularity in mind, BluRoX technology allows for easy repair and material reuse, contributing to a more sustainable and environmentally responsible lifecycle.

Outer shell material

The outer casing is made of galvanized sheet metal, featuring a white lacquered exterior and a coated inner layer. These materials provide a sturdy structure for the appliance, support the white finish, and serve as the contact point for the door seal magnet.

High-barrier foil

The high-barrier foil consists of several plastic layers and an extremely thin, metallic barrier layer. The plastic layers can be bonded to the surrounding components by heat and separated from each other again. The thin metal layer made of aluminium reduces gas ingress and thus reliably secures the vacuum over a long period of time.

Evacuated perlite

Perlite, a finely ground volcanic rock, provides very low thermal conductivity. When combined with a vacuum, the best insulation possible, it makes our BluRoX technology exceptionally energy efficient.

Interior lining

Made from durable PS, the inner container combines function and style. It features technical contours for glass shelves, ceiling light mounts, and side wall connections, ensuring a sleek and efficient design.

Efficiency of vacuum insulation over time

FNb 505i – our first freezer with BluRoX

BluRoX is already available – in the door of our FNb 505i freezer. The groundbreaking vacuum perlite technology offers an unprecedented and extremely efficient cold insulation. Thus, freezers can achieve top values in energy efficiency. In addition, the materials in the door can be sorted and reused at the end of their service life.

Materials

Materials used in refrigerators and freezers come into contact with food and must therefore meet specific criteria. At Liebherr, we ensure compliance with food safety standards.

We are committed to continuously increasing the proportion of recycled materials in the future.

Where do we stand?

Currently, we are unable to procure sufficient quantities of recycled materials for plastics and glass that meet these requirements. In the case of steel, the recycled content could not be reliably demonstrated by our suppliers.

About EcoVadis

We use EcoVadis to quantify our progress in the areas of corporate responsibility and sustainability. Our commitment to a holistic corporate strategy has now been rewarded: The EcoVadis gold medal and our position in the top 3% of all the award-winning companies makes it clear that we are facing up to ecological, social and ethical challenges.
