Breezaire WKL Wine Cellar Cooling Units

Breezaire WKL Series units are considered among the best for maintaining stable wine cellar environments. They are designed for quiet operation, consistent temperature control, and long-term durability. The WKL 4000, for example, is a popular choice for mid-sized cellars due to its reliability and ease of installation.

Yes—if you want to maintain proper wine storage conditions year-round. A cooling unit keeps the temperature between 55–58°F and humidity at ideal levels, preventing wine from aging too quickly or spoiling.

Most experts recommend setting it to 55°F (13°C), which is the optimal temperature for aging and preserving wine.

The lowest-cost option is to build your cellar in a naturally cool and insulated space, such as a basement, which reduces the need for mechanical cooling. However, for precise control—especially in warmer climates—a small, energy-efficient self-contained unit like a Breezaire WKCE model is often the most cost-effective long-term.

ensuring adequate ventilation can extend its lifespan.

No. A standard refrigerator runs around 35–40°F, while a wine cooler maintains 45–65°F depending on the type of wine stored.

Use high R-value insulation (R-19 for walls and R-30 for ceilings), install a vapor barrier to prevent moisture issues, choose a quality cooling unit such as Breezaire, and minimize light and heat sources inside the space.

Yes—for wine storage purposes. Wine coolers maintain a stable, slightly warmer temperature with proper humidity, while refrigerators are too cold and dry for long-term preservation.

Set your cooling unit to 55°F for red wines. White wines can be stored slightly cooler, but 55°F is an excellent universal setting.

Yes. Temperatures below 45°F can slow the aging process excessively and even risk freezing in extreme cases. Constant low temperatures may also affect cork integrity over time.
