What Makes Our Silent Wine Refrigerators “Silent”?

Why do we call our popular line of wine refrigerators Silent Wine16 Bottle Silent Refrigerators?
Because of thermoelectric technology. Since our units are built with a thermoelectric cooling system instead of a typical compressor, the result is what we like to refer to as “pin-drop quiet performance.” Rather than having a loud compressor, thermoelectric semiconductors reduce noise and vibration, two powerful enemies of wine. Noise and vibration interfere with the biochemical process of wine maturation and are often fatal to the best wines.

What is thermoelectricity?
Scientifically speaking, thermoelectricity is a phenomena in which an electric potential creates a temperature difference. Our thermoelectric wine refrigerators consist of a semiconductor and heat sink. Once the electricity is passed through the semiconductor, there is movement between the molecules of the materials used for the semiconductor. This will begin to create the cold and hot temperatures necessary to keep wine at proper storage temperatures. One side of the semiconductor will be hot and the other side will be cold. Fans are used to move the cold air through the unit and push out hot air out through the vents in the back.

Bonus! Thermoelectric Wine Refrigerators are energy-efficient and eco-friendly.
Thermoelectric wine refrigerators are more energy-efficient than your average refrigerator simply because there are no moving parts, and the smaller cooling capacity requires less energy to cool. They are also environmentally friendly, as no CFC-, HCFC-, or HFC-type refrigerants are involved in the cooling process. And when your unit finishes its lifecycle and needs to be disposed of, it has no toxic chemicals that may harm the water, air, or ground.


Where should you place a Silent Wine Refrigerator?
Since thermoelectric cooling is very quiet, it is ideal for kitchens, living areas, and offices. While thermoelectric cooling offers many benefits, the cooling performance of thermoelectric units tends to strongly correlate to the environment in which the units are located. That being said the external ambient temperature (or, the temperature of the room the unit resides in) should not have extreme fluctuations. The unit’s overall performance is generally linked to the outside temperature. In light of the above, it is helpful to note that thermoelectric wine refrigerators are designed for use in a “room temperature” environment.

  1. I own one of the Silent Wine Refrigerators. I keep it in my den which has a temperature range of about 68-72 degrees. Equally as important I have space off of the back, top, and sides of the unit to ensure the unit vents properly. The unit has been holding tight at 55 degrees and as quiet as advertised!

  2. My unit will only maintain 54 degrees! Nothing else. it is worthless for reds. I keep it in the gqarage, unplugged, since Habitat will not accept it.

  3. Hi Bruce– I’m sorry to hear you are disappointed with your unit but 54 is actually a perfect temperature to store wine at, including reds. It sounds like your unit is in good condition. Please take it out of your garage and put it to some good use!

    We just purchased the 12 bottle capacity cooler…….we placed 12 room temperature bottles of wine in the unit….and set the temperature to 55 degrees… long will it take to reach the desired temperature, it was 73 degrees after we placed all the bottles in.

  5. Hi George, thanks for your comment. It should take a day to reach the desired temperature. It can change based on the # of bottles in your unit, but since you only have 12 bottles, that is all it should take. Has the unit chilled accordingly now?

    Yes it has, thanks!

  7. I’m very much in favor of using this type of cooling – another word for devices that use this thermoelectric principle is the “Peltier Cooler”. The drawback is that it’s a highly inefficient way of cooling, basically the other side of the Peltier device will be extremely hot, not unlike the condenser coils on a classical fridge. But like this article is emphasizing, there is absolutely no noise.

  8. I have two coolers and they really are silent. The 12 bottle unit I’ve had for 2 years in a small space next to the china cabinet. Last year I needed a larger one and I found a 28 bottle unit here in south Florida at the local department store. That one was a little harder to hide but it still looks ok in the corner of the dining room. Temperature in the house stays between 77 and 79 degrees constantly. I have no problems so far keeping both units at 55, and they both are very quiet.

  9. I’ve had the 12 bottle silent refrigerator for just about a year now. it has worked pretty well so far except that when the room gets warm as it tends to do in the summer it seems that the unit has some trouble staying at the set temp. is this normal?

  10. i have the 12 bottle silent fridge thats not silent anymore. its 3 years old and i traced the noise to the left fan. any way to oil, or remove and clean ? any ideas or thoughts will help.
