The Kalorik 16 Bottle Eco-Friendly Wine Refrigerator stores wine at optimal temperature and humidity, keeping it safe and ready to enjoy. Digital controls with an LCD display make it easy to set the temperature. The unit can be set from 52 to 64 degrees (F). The insulated cavity provides 3 shelves with a wooden panel to cradle and display your bottles of wine. The unit also comes with a state-of-the-art thermoelectric cooling system which avoids vibrations caused by compressor cooling systems. Such vibrations disturb the sediments in wine, disrupting the aging process. Without vibration, stored wine can age naturally. Even more, the unit's environmentally friendly thermoelectric cooling system uses no damaging Freon which can harm the planet; offers energy efficiency, only using about as much energy as a 75-watt light bulb; and delivers ultra-quiet operation with minimal noise generated from the only moving part - the ventilating fan. Other thoughtful details include soft interior LED lighting with an ON/OFF switch, automatic defrost, a Celsius and Fahrenheit switch, a stainless steel door frame, an adjustable leveling foot, and double-paned tempered glass. Stop ruining your good wines through incorrect storage!
