Through-the-Wall Wine Cellar Cooling System for Cellars Up to 1000 Cu. Ft.
The Breezaire WKL 4000 is a self-contained, through-the-wall wine cellar cooling unit designed for properly insulated wine cellars up to 1000 cubic feet.
It delivers 4000 BTUs of cooling power, operates on 115V (7 amps), and vents warm air through the rear into an adjacent space.
This model is ideal for residential wine rooms that require stable 50–59°F storage without installing a split system.
Also available in Breezaire WKL 1060 for up to 140 cu. ft., Breezaire WKL 2200 for up to 265 cu. ft., Breezaire WKL 3000 for up to 650 cu. ft., Breezaire WKL 6000 for up to 1500 cu. ft., Breezaire WKL 8000 for up to 2000 cu. ft.
30-Second Decision Summary

Installation Type: Through-the-wall (rear exhaust)
Electrical: 115V / 60 Hz / 7A
Noise Level: Comparable to a household refrigerator

Not For: Open rooms, garages, glass-heavy uninsulated spaces
If your cellar meets insulation and ventilation requirements, this unit provides reliable long-term wine preservation.
Cooling Performance & Wine Protection
The WKL 4000 is engineered specifically for wine storage, not comfort cooling.
It maintains:
- Stable cellar temperatures between 50°F–59°F
- Consistent cycling to reduce temperature swings
- Automatic humidity support through evaporator design
- Low vibration operation for proper aging conditions
When installed in a properly constructed cellar, it supports long-term aging at approximately 55°F.
Real-World Sizing Guidance
| Cellar Size | Performance Expectation |
|---|---|
| 500 cu. ft. | Strong performance margin |
| 750–850 cu. ft. | Ideal operating range |
| 900–1000 cu. ft. | Upper capacity limit (must be well insulated) |
Performance may decrease if:
- Insulation is inadequate
- Vapor barrier is missing
- Door seals leak air
- Exhaust room is excessively hot

📚 Frequently Asked Questions (FAQs)
Noise levels are comparable to a household refrigerator. If near-silent operation is required, a split system is a better choice.
If the cellar exceeds 1000 cu. ft., especially with glass walls or poor insulation, the unit may struggle to maintain stable temperatures. In those cases, a higher-capacity model is recommended.
Yes, provided the rear exhaust vents into a ventilated room that can dissipate heat. It must not vent into a sealed cavity or confined space.
It operates at 115V and draws 7 amps. A dedicated circuit is recommended to prevent overload and breaker trips, especially if other appliances share the line.
Yes. The evaporator design automatically supports proper humidity levels in a sealed cellar. Separate humidification is typically not required in properly constructed wine rooms."]
