It adopts a brand-new cooling technology: cooling via film chip instead of a compressor, making it completely different from traditional cooling systems. It will start working immediately when it is turned on, because of its adoption of CO₂ and H₂O as its refrigerant inside the heat-exchange tube. It is stable and causes no vibration when working as it does not have a compressor. It is always keeping cool, no temperature fluctuation, different from wine cellars with compressors. And its glass door, with UMI, blocks light to minimize the effect of sunlight to wine, while it becomes transparent when users approach, due to a human sensor.
