In addition to the usual premium line of refrigerators, Liebherr has the most charged Premium Plus series. It defines flagship units with top-end equipment and assembly according to the highest canons of the vaunted German quality. All refrigerators of the family are available in multi-chamber layouts with the arrangement of chambers one above the other, side-by-side behind different doors (Side-by-Side), with freezers at the bottom and swing doors to the refrigerator (French-Door).

The facades of the Premium Plus series units are made of alloy steel with a SmartSteel coating. The interior of the refrigerators is illuminated by LED lighting (including this applies to freezers). The cooling circuits of the family models are separate, and the number of compressors for Side-by-Side and French-Door layouts is two (Duo Cooling).

The French-Door layout is a new word in the design of refrigerators. In this format, some of the top models of the Liebherr Premium Plus class are produced.

Vario Space is implemented in the "interior" of refrigerators for the convenience of loading oversized dishes and products. Another mandatory attribute of the Premium Plus class is improved freshness zones. Fast and high-quality freezing is also at the forefront. Access to the refrigerator settings is opened by tapping on the touch panel or from a paired smartphone via a mobile application. Finally, it would be useful to mention the high energy efficiency of the series equipment. However, the refrigerators of the improved premium class are also worth it.
