The refrigerator and freezer sections have separate cooling circuits which ensure an optimum climate in both. In addition, there is no air exchange between the two areas. This prevents food in the fridge section from drying out, and odors from fish, onions, or cheese, for example, are not transferred to food in the freezer section. In addition to the DuplexCool functionality, DuplexCool Pro provides maximum cooling with two separate compressors – one for each cooling circuit. DuplexCool Pro is therefore the professional solution as it provides the safest storage conditions for your food in bottom-mount units.
