Wine collectors agree that the ideal temperature for maturing fine wines is 55F-60F and that the humidity should be carefully balanced between 50%-70%.

WhisperKOOL achieves these optimum conditions by cooling the cellar slowly. As the temperature in the cellar begins to drop, the relative humidity will rise, creating the ideal environment for aging wine. WhisperKOOL incorporates an efficient environmental stabilization system in compact, easy-to-install, self-contained units or more advanced split systems. Cooling units and systems are built in a variety of sizes for wine cellars, ranging from 300 to 2,000 cubic feet (properly insulated and sealed environments).

The unique difference between the WhisperKOOL system and traditional air-conditioning units is the maintenance of well-conditioned humidity. Traditional air-conditioning units are designed to cool air quickly; as a result, humidity is removed, leaving air dehydrated.
