The unique difference between the WhisperKOOL systems and traditional air conditioners is the maintenance of well conditioned humidity. Traditional air conditioning units are designed to cool quickly: as a result, humidity is removed below acceptable levels which can lead to dried out corks and oxidized wine. WhisperKOOL achieves the optimal results by cooling the air slowly, cycling down the temperature while maintaining humidity between 50% and 70% in a properly prepared wine cellar.
