Liebherr’s NoFrost appliances provide expert refrigeration technology to ensure long-term freshness. The food is frozen with chilled recirculating air, and any humidity is expelled. As a result, the freezer is always free of ice, and food no longer frosts over. NoFrost convenience makes defrosting a thing of the past. The automatic SuperFrost function makes freezing simple and saves energy. It quickly reduces the temperature to -32 °C and thus creates the cold air required to preserve vital vitamins. The child lock is programmed so as to prevent the appliance being inadvertently switched off.
