SmartFrost technology reduces ice build-up compared to traditional static freezers, making defrosting less frequent and easier to manage. The VarioSpace system adds flexibility by allowing drawers to be removed, accommodating larger frozen items when needed. Touch controls provide effortless operation, while the integrated control panel lock prevents accidental adjustments. A temperature range from -15°C to -28°C ensures optimal freezing conditions, and the four-star freezer rating guarantees food remains preserved for extended periods.
For added convenience, the freezer includes an open-door alert with both visual and audible warnings, helping to prevent energy waste and food spoilage. A temperature warning system also provides notifications in case of fluctuations, ensuring contents remain at the correct storage temperature. In the event of a power failure, the unit offers a storage time of up to 17.5 hours, keeping food safely frozen until power is restored. The built-in power failure alarm further enhances peace of mind by alerting users to potential issues.
Operating at just 34 dB, the SUFD3603 is exceptionally quiet, making it ideal for open-plan spaces or households that prioritise low-noise appliances. It has an annual energy consumption of 140 kWh, with an energy efficiency rating of D. While it is not frost-free, its efficient design and SmartFrost technology help minimise maintenance. The freezer does not require plumbing and comes with an ice cube tray for added convenience.
Designed for durability and ease of use, the SUFD3603 features integrated rails for smooth drawer movement and a replaceable door seal to extend its lifespan. It also includes a Sabbath mode, catering to specific user needs. The fixed hinge ensures stability, while the lack of an interior light maintains energy efficiency. Though it is not suitable for outbuildings or garages, it performs optimally in indoor environments with a minimum room temperature of 10°C.
A well-balanced combination of practicality and innovation, the Liebherr SUFD3603 provides reliable freezing performance with thoughtful features to enhance everyday use. With a sturdy build, flexible storage options, and advanced safety alerts, it is an excellent choice for those seeking a high-quality, built-under freezer that delivers efficiency and convenience in a compact design.
