The Siemens GI81NAC30A 221L Integrated Built In Freezer with no - Frost technology, Soft - Closing, and Super - Freezing. No more defrosting: the no - Frost technology - With no - Frost, a ventilation system diverts the humidity from the freezer compartment. As a result, the air remains dry. This reliably prevents frost from forming on the inside of the appliance or on your food. Key Features Freeze super large quantities super fast: super - Freezing - To prevent thawing of frozen foods when placing large quantities of new food in the freezer, simply activate the super - Freezing button before going shopping. The appliance will then automatically cool down to a temperature as cold as –30 °C so that newly stored foods do not interrupt the freezing process. Ideal for large frozen food items and much more: the big - Box - An entire leg of lamb, several pizzas, or a tall container full of freshly picked blueberries – for especially large or cumbersome food items you need an extra-large storage space. The big - Box gives you plenty of space to accommodate and stack everything. And when you need an even larger space, all the drawers and shelves can be easily removed from the freezer compartment, quickly putting the entire freezer space at your disposal. Soft - Closing Door - The door closes automatically and softly when it is open at a 20° angle or less. Constant temperature - By intelligent sensor technology. Multiairflow system - Minimises fluctuating temperatures by ensuring optimal and uniform air circulation in the fridge.
