This freezer of full-colour crystal glass uses a four-dimensional air-cooling technology and thus solves the problem of ice formation. A waterfall air supply combines the air-cooled, frost-free technology with a 360-degree air supply, freezes evenly with a large volume of air, locks up the cell moisture quickly and assures freezing and preservation at cell level. An antibacterial coating ensures hygienic storage. Blue light in the area of the stable aluminium handles indicates the high cooling power.
