Liebherr ICNb 5123 Plus 70/30 Integrated Fridge Freezer
The Liebherr ICNb 5123 integrated fridge freezer is a fully integrated, frost-free appliance designed for a 178cm kitchen housing unit. Its practical 70/30 split provides 253 litres of total storage, comprising a 183-litre fridge and a 70-litre freezer.
With a B energy rating and an exceptionally low 29 dB noise level, the Liebherr ICNb5123 is ideal for open-plan kitchens and households looking for efficient, unobtrusive food storage.
Why choose the Liebherr ICNb5123 Plus integrated fridge freezer?
Choose the ICNb 5123 Plus if you want an integrated fridge freezer that keeps everyday food fresher with less upkeep. EasyFresh, NoFrost and DuoCooling work together to protect produce, prevent freezer ice and reduce odour transfer. Its 253L capacity suits smaller to medium households, while touch controls, SoftSystem closing and smart-home readiness via an optional SmartDeviceBox add useful convenience.
EasyFresh Storage for Fruit and Vegetables
The EasyFresh Safe provides suitable storage conditions for unpackaged fruit and vegetables. Its airtight closure allows humidity to rise naturally, helping food stay fresh for longer.
Integrated drawer runners and a pull-out stop make the EasyFresh compartment easy to open and close. The rails also help the drawer close securely, keeping chilled food stored under suitable conditions.
NoFrost Freezer Convenience
NoFrost technology protects the freezer compartment from unwanted ice and frost build-up. This removes the need for time-consuming manual defrosting while helping the freezer operate efficiently.
The 70-litre freezer also features VarioSpace. Individual freezer drawers can be removed to create extra-high storage space for larger or unusually shaped frozen items.
DuoCooling and PowerCooling
DuoCooling uses two completely separate refrigeration circuits, preventing air from being exchanged between the fridge and freezer compartments. This helps reduce odour transfer and prevents food from drying out.
The PowerCooling system uses a powerful yet quiet fan to distribute cold air efficiently throughout the refrigeration compartment, helping maintain an even temperature.
Ultra-Quiet B Rated Performance
With Liebherr’s UltraSilent design, this quiet integrated fridge freezer operates at just 29 dB. Its low-noise performance makes it especially suitable for open-plan living spaces.
The appliance carries a B energy rating and includes an EnergySaver mode. When activated, EnergySaver increases the standard temperature by two degrees, reducing power use while keeping food suitably fresh.
Touch Display and Intelligent Functions
The clear touch display provides easy, intuitive control. Functions and temperature settings are clearly arranged and can be selected with a gentle tap.
SuperCool temporarily boosts cooling performance after fresh groceries have been added, helping them reach the temperature of the existing fridge contents. The function switches off automatically when it is no longer required.
SuperFrost increases freezer cooling capacity when unfrozen food is added, helping maintain a constant temperature. It can be switched off manually or will deactivate automatically after 65 hours.
CleaningMode switches off refrigeration while leaving the interior lighting on, making it easier to see while cleaning the appliance.
HolidayMode switches off the fan and SuperCool function while regulating the fridge temperature to +15°C. This helps save electricity and prevent unpleasant odours while the freezer compartment remains switched on.
Display Lock and Safety Alarms
The display lock helps prevent temperature settings and functions from being changed unintentionally. It can be deactivated whenever required.
A configurable door alarm uses a flashing light and warning tone if the door remains open for too long. The alert can be set to activate after one, two or three minutes.
The temperature alarm provides both an audible and visual warning if the freezer reaches a critical temperature. The display also indicates how far the temperature has risen, and the alarm can be switched off manually.
SabbathMode switches off the lighting, displays and sounds generated by actions, including alarms. It deactivates automatically after 80 hours.
SoftSystem Fixed-Hinge Installation
The Liebherr ICNb 5123 Plus is designed for fixed-hinge integrated installation and features a customer-reversible door. The SoftSystem mechanism allows the fridge door to close softly, securely and quietly, helping keep bottles in the door shelves stable.
The required installation aperture measures 177.2 to 178.8cm high, 56 to 57cm wide and 55cm deep.
Flexible Interior Storage
The fridge provides enough space to slide in a baking tray, allowing items such as a prepared pizza or home-baked fruit pie to be stored easily. The tray can be inserted and removed when the door is open at 90°.
Height-adjustable glass shelves can be repositioned quickly to accommodate larger containers, even when food remains stored on the shelves.
The VarioSafe provides an organised space for smaller items such as yoghurt pots, jam jars and tubes. Its two-stage height adjustment allows it to be positioned where it is most convenient.
The compact FlexCube has differently sized openings for storing items such as small tubes, open cream cups and quail eggs. It fits in Liebherr bottle and can racks, and several FlexCubes can be placed inside the fridge. The FlexCube is also dishwasher safe.
A removable three-bottle shelf securely holds three bottles and can be positioned on any glass shelf. It can be removed whenever the space is needed for other food.
Clear LED Interior Lighting
LED ceiling lighting illuminates the refrigerator from above for a clear view of the contents. The LEDs are positioned in front of the glass shelves, helping keep the interior well lit even when the fridge is full.
FreshAir Odour Reduction
The FreshAir activated charcoal filter is positioned directly in the airflow within the fan housing. It helps neutralise unwanted food odours, while the display provides a reminder when the filter needs to be changed.
SmartDeviceBox Connectivity
A compatible SmartDeviceBox can be retrofitted separately, allowing the Liebherr fridge freezer to connect to the internet and access compatible connected features.
With the required app connection, BottleTimer activates SuperFrost to chill a bottle quickly and sends a reminder when it has reached the required temperature.
Practical Accessories
The supplied egg tray stores up to 10 chicken eggs and can be positioned either in the inside door or on a glass shelf.
The freezer’s ice cube tray produces up to 21 ice cubes. The size of each cube can be adjusted by changing the amount of water used.
The replaceable door seal can be removed and fitted again in a few simple steps, helping keep this area of the appliance clean and hygienic.
Selected removable features, including the butter dish, FlexSystem and ice cube tray, can be cleaned in the dishwasher for added convenience.
