The WhisperKOOL is a user-friendly environmental stabilization system perfect for entry-level wine storage. It is affordably priced and easy to install. The unit should be installed within 18 inches of the top of the room in order to achieve maximum cooling. An unobstructed airflow and adequate ventilation will be required to dissipate the heat generated by the unit.

“How To Build Your Own Wine Cellar” devotes an entire chapter to wine cellar cooling to help you choose the best cooling system for your cellar.
