Breezaire Wine Cellar Cooling Units
Breezaire has been building wine cellar cooling systems in the United States since 1985. Self contained through the wall units that mount in a wall and plug into a standard outlet, and split systems that let the noisy half sit up to fifty feet away. Breezaire designs these units to remove only excess moisture, aiming...

Breezaire WKL vs WKSL: choosing your cooling system.
Breezaire makes two kinds of wine cellar cooling. WKL units are self-contained and mount through a wall. WKSL systems are split: a fan coil inside the cellar and a condensing unit placed elsewhere. Both are designed to hold a selectable temperature of about 48 to 63Β°F in a properly built cellar.
| Topic | WKL through the wall | WKSL split system |
|---|---|---|
| How it works | One self-contained unit set into an opening in the cellar wall. The cold side faces the cellar and the warm side exhausts into the space next to it. | Two modules: a fan coil mounted inside the cellar and a condensing unit placed elsewhere, connected by two copper lines and low voltage wiring. |
| Equipment placement | The warm side needs at least 3 ft of unobstructed airflow into a well ventilated space. Breezaire lists unventilated laundry rooms, closets, bathrooms, garages, crawl spaces, attics and humid basements as unsuitable for the exhaust. | Fan coil within 6 in of the ceiling with 3 ft of open airflow in front. Condensing unit on a solid base with 1 ft clear on all sides and 3 ft for exhaust, raised above possible flooding and shaded. Up to 50 ft per line, less 10 ft for each hard 90Β° bend. |
| Installation requirements | Ships charged with refrigerant. Mount upright in the wall opening, attach the warm side exhaust grille and plug into a GFCI outlet on its own circuit. A pull-down drain tube is there for occasional excess condensate. | Ships as components, not a working system. Breezaire recommends a licensed refrigeration technician to connect, pressure test, evacuate and charge it on site. The fan coil needs a condensate drain line, and wiring follows the manual and local code. |
| What you buy | One complete unit with the Sentry III+ digital control. | Fan coil with the Sentry III+ control, condensing unit, sight glass and filter dryer. Confirm the copper line set, insulation and drain parts with your installer. |
| Models we carry | WKL 1060 to WKL 8000, for cellars up to 140 to 2,000 cu ft. | WKSL 2200 (up to 265 cu ft) and WKSL 4000 (up to 1,000 cu ft). |
Humidity
Breezaire designs both lines to remove only excess moisture, aiming for 50 to 75% relative humidity in a properly sealed cellar with a vapor barrier. The units do not add moisture, and Breezaire notes that in very dry conditions that range may not be reached without adding moisture. Actual room humidity depends on how the cellar is built, so it is not guaranteed.
Sizing
The cubic foot ratings assume a properly insulated cellar without glass doors or windows, and Breezaire states that the buyer must determine whether a unit suits a specific room. Read the WKL installation instructions or the WKSL installation instructions before you build.
