One of the standout features of the KG39NAIAU is its Total NoFrost technology, which prevents ice build-up in both the fridge and freezer compartments, eliminating the need for manual defrosting. The appliance also features twin evaporators, allowing independent temperature control for each compartment, which helps maintain optimal conditions and prevents odour transfer between the fridge and freezer. Temperature ranges from 2°C to 8°C in the fridge and -16°C to -24°C in the freezer, with precise electronic controls displayed via dual LED chains.
The HyperFresh drawer is designed to keep fruit and vegetables fresher for longer by maintaining ideal humidity levels. Additional convenience comes from features like the SuperFreezing function, which rapidly freezes newly added items to preserve taste and texture, and the MultiAirFlow system, which evenly distributes air to keep food chilled consistently.
With an energy efficiency rating of A and an annual energy consumption of just 112 kWh, the KG39NAIAU helps reduce running costs and environmental impact. It operates at a very quiet 29 dB, making it suitable for open-plan living spaces. The appliance also includes a visual and audible door open alert, ensuring that the door is never accidentally left ajar.
Designed with practicality in mind, the fridge freezer includes height-adjustable shelves, a bottle rack, an egg tray, and interior LED lighting with a soft-start feature. The stainless steel doors have an anti-fingerprint coating for easy maintenance, and the vertical door handles provide a clean, modern look. The door is right-hand hinged but reversible, allowing flexible placement in your kitchen. Adjustable feet help ensure stability on uneven surfaces, and the flame-retardant back adds peace of mind.
Built to perform in room temperatures ranging from 10°C to 43°C (climate class SN-T), this appliance is not suitable for garages or outbuildings. However, its built-in safety features, including a power failure safe storage period in the freezer and a temperature warning system, add to its reliability.
The Siemens KG39NAIAU is a premium choice for anyone seeking a frost-free, energy-efficient, and quietly powerful fridge freezer, combining German engineering with thoughtful design and everyday convenience.
