Through the Wall Cooling Units For Large Cellars

The best wine cellar cooling unit is one that maintains stable temperature and humidity without excess noise or vibration. Breezaire units are a trusted choice because they are designed exclusively for wine preservation. Their WKSL split systems offer quiet operation with flexible installation, while the WKCE series provides simple through-the-wall solutions for smaller cellars.

Yes. Without a cooling unit, even underground cellars can experience temperature and humidity fluctuations that damage corks and wine quality. Breezaire cooling systems ensure your cellar stays within the ideal 55°F range with natural humidity retention.

For small to medium-sized spaces, a through-the-wall self-contained system like Breezaire’s WKCE Series is often the most cost-effective. These units install easily into an interior wall, don’t require ductwork, and provide reliable cooling at a lower upfront cost compared to split or ducted systems.

With proper ventilation, installation, and care, Breezaire cooling units typically last 8–12 years, and often longer. Regular maintenance, like cleaning filters and ensuring good airflow, extends the life expectancy.

Breezaire units require proper ventilation on the condenser side to release warm air. For self-contained models, this means installing them where exhaust air can circulate freely in an adjacent room kept below 85°F. Poor ventilation can shorten the unit’s lifespan.
