Liebherr 24" standing Bottom zer Refrigerator comes with 12.7 cu. ft. Total Capacity for all your refrigeration needs. Additionally, it has DuoCooling, a dual refrigeration system that maintains optimal settings in the zer and refrigerator to increase food shelf life and flavor retention. The refrigeration system's parts, including fans, evaporators, compressors, and valves, are correctly matched and designed to work together to provide SuperSilent's incredibly silent operation. Additionally, while your refrigerator is in HolidayMode, it turns off the fan and SuperCool and raises the temperature to +15 °C. This avoids offensive odors while also saving electricity. Naturally, the zer section is turned on.
