The plastic inner liner is made of polystyrene: a fully recyclable, robust, and odourless plastic. Manufactured seamlessly from one piece, it has no hidden dirt traps, and the large, rounded corners can be cleaned quickly and easily. It’s the perfect combination of sustainability and hygiene.
SmartFrost greatly reduces the frost build-up in the interior and on stored products. Defrosting is required less often and when it is necessary, it is made much easier by the smooth, easy-to-clean interior walls. The evaporator is embedded in foam insulation, ensuring high energy efficiency and uniform cooling. Static cooling system.
Rising electricity prices are increasing the demands on the efficiency of refrigerators and freezers. From the compressor to the seal, to the lighting and electronics, Liebherr fully utilises the savings potential of every component. The result is impressive especially in terms of total operating costs.
Sensitive substances cannot be subjected to large deviations from the set storage temperature. These freezers guarantee a temperature fluctuation of no more than ±5 °C, so that the valuable goods you store in them are optimally protected and their quality is preserved. Freezers have ±5 K deviation from setpoint and calibration option.
