🧭 Why Ductless Cooling Is Changing the Game
By Jim Hopper, Wine Cooling Expert
When building a wine cellar, choosing the right cooling system is everything. Many collectors start with self-contained units — but more and more are turning to ductless split systems for quieter, more flexible, and vibration-free climate control.
Breezaire’s WKSL series is a standout in this category, offering precise control without the noise and constraints of traditional setups.

🧊 What Are Ductless Wine Cellar Cooling Units?
A ductless wine cellar cooling system (also called a split system) separates the cooling components into two parts:
- The evaporator sits inside or near the cellar.
- The condenser is located in a different room or outdoors.
This means no bulky through-wall units, less noise inside your cellar, and zero mechanical vibration where your wine lives.
Breezaire’s WKSL Series is designed specifically for wine collectors who want aging-focused precision and quiet operation in homes or custom cellars.

✅ Is This the Right Choice for Your Cellar?
Ask yourself the following:
- Do you want quiet performance for a home or near-living-space cellar?
- Are you aging wine long-term (not just storing short-term)?
- Does your space allow for an outdoor compressor or mechanical room?
- Do you want more control over airflow and unit placement?
- Are aesthetics and non-invasive installation important?
If yes, the Breezaire WKSL series is likely the perfect fit.
