The ICBNH 5173 fully integrated fridge-freezer featuring Bio - Fresh with Hydro - Breeze and internal Ice - Maker (plumbed) provides an elegant solution for a perfect, seamless kitchen, thanks to Liebherr’s door on door technology. With Liebherr’s No - Frost technology, 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. No - Frost convenience makes defrosting a thing of the past. With Duo - Cooling providing two completely separate cooling circuits, there is no air exchange between the refrigerator and freezer compartment. This prevents odour transfer and stops the stored food from drying out.
