NoFrostThe NoFrost system from Liebherr provides rapid fan-assisted frost-free freezing for the safe longterm storage of food. The NoFrost technology creates a much larger storage capacity and keeps the freezer constantly frost-free. DuoCoolingAccurate and independent temperature control of the refrigerator compartment and freezer compartment of combined fridge-freezers is achieved through DuoCooling with two completely separate cooling circuits. And there is no air exchange between the refrigerator and freezer compartment. This prevents odour transfer and stops the stored food from drying out. PowerCooling SystemThe high-performance PowerCooling system rapidly cools down freshly stored food and creates an even cooling temperature throughout the interior. A door contact switch turns the fan off when the door is opened.This saves valuable energy. Bottle RackThe bottle rack is a solution for storing beverages which is both practical and pleasing to the eye. Here bottles can be stored within a compact space. SuperCoolThe automatic SuperCool function lowers the refrigerator temperature down to as far as +2 °C for as long as 12 hours - ideal for rapidly cooling freshly stored food. Door AlarmThe audible door alarm alerts the user if the door has been open for longer than 60 seconds for safe protection of the food. Child lockThe child lock is programmed so as to prevent the appliance being inadvertently switched off.A symbol in the MagicEye indicates when the child lock is switched on. FrostSafeWith the FrostSafe the extra-high and removable drawers are closed all round. This means that the cold cannot dissipate so quickly when the appliance is opened. The transparent front of the compartments guarantees an optimum overview of the frozen items. VarioSpaceFreezer drawers and toughened glass shelves can be removed. VarioSpace – the practical storage solution for larger items. Transparent Vegetable BinsTransparent vegetable bins provide plenty of space for the organised storage of fruit and vegetables. In addition they are easy to clean. Reversible Door HingesThe appliances are factory fitted with door hinges on the right. The reversible door hinges permit optimum use of the appliance wherever it is located. SmartDeviceLiebherr appliances labelled with a "SmartDevice" logo can be networked to the SmartDeviceBox which allows the appliance to access further services and be controlled remotely from a computer or mobile device. The SmartDeviceBox is available as an accessory. However appliances with the letter i in their model name (for example Kbi 4350) already have the SmartDeviceBox integrated as standard. Key Features .
