Breezaire WKL 3000 Wine Cellar Cooling Unit

Is the Breezaire WKL 3000 the right unit for a 500–650 cubic foot sealed wine cellar?

If your cellar is properly insulated, vapor-sealed, and requires a self-contained through-the-wall cooling system, the WKL 3000 is designed specifically for that application.

If your room exceeds 650 cu ft or includes significant glass exposure, this unit may be undersized.

Quick Summary

The Breezaire WKL 3000 is a 3,000 BTU through-the-wall wine cellar cooling unit rated for sealed wine rooms up to 650 cubic feet. It operates on 115V (5 amps) and exhausts warm air from the rear of the unit. It features electronic temperature controls, LED display, automatic humidity management, and automatic defrost.

Proper insulation and ventilation are required for rated performance.

Also available in: WKL 1060 (up to 140 cu ft), WKL 2200 (up to 265 cu ft), WKL 4000 (up to 1000 cu ft), WKL 6000 (up to 1500 cu ft), WKL 8000 (up to 2000 cu ft).

Who This Model Is For

The WKL 3000 is appropriate for:

• Sealed residential wine cellars between 500–650 cu ft
• Collectors storing approximately 250–700 bottles
• Rooms with R-19 wall insulation and R-30 ceiling insulation
• Installations where rear exhaust space is available
• Homeowners preferring a self-contained unit (no split condenser)

Who Should Not Use This Model

The WKL 3000 is not recommended for:

• Open basements or unfinished rooms
• Cellars larger than 650 cu ft
• Rooms with extensive glass without load calculations
• Poorly insulated or unsealed spaces
• Commercial wine storage applications
• Installations without proper exhaust ventilation

Using this unit outside rated conditions will reduce cooling performance and may void warranty coverage.

Cooling Performance & Real-World Capacity

The WKL 3000 delivers 3,000 BTUs of cooling power and is rated for up to 650 cubic feet under the following conditions:

• R-19 insulated walls
• R-30 insulated ceiling
• Vapor barrier installed
• Airtight insulated door
• Ambient exhaust area within acceptable limits
• Minimal glass exposure

Performance Decreases When:

• Insulation is below recommended levels
• The cellar includes large glass panels
• Exhaust space becomes excessively hot
• Door openings are frequent
• The room exceeds rated cubic footage

If your cellar is near 650 cu ft, upsizing to the next model may provide better long-term stability.

Installation Requirements

The Breezaire WKL 3000 is a through-the-wall system designed to mount into a framed wall opening.

Installation Checklist

• Dedicated 115V, 60Hz electrical supply
• 5-amp circuit capacity
• Proper framing and wall support
• Rear exhaust clearance
• Ventilated exhaust space
• Fully insulated and vapor-sealed cellar
• Unit weight: 76 lbs (structural support required)

Professional installation is recommended to ensure proper ventilation and compliance with manufacturer guidelines.

Noise Profile

Because the compressor is integrated within the unit:

• Produces moderate operational noise
• Suitable for dedicated cellar rooms
• Louder than split systems
• Not recommended for shared bedroom walls

If near-silent performance is required, a split system may be more appropriate.
