Breezaire WKSL 4000 Wine Cellar Cooling Unit
The Breezaire WKSL 4000 Wine Cellar Cooling Unit is a premium split-unit cellar cooler engineered to maintain ideal conditions for wine storage in cellars up to 1,000 cubic feet. With its robust cooling capacity, automatic humidity regulation, and vibration-free, ultra-quiet operation, the WKSL 4000 ensures your collection ages gracefully in a stable and protective environment. Whether for a home cellar or a commercial wine room, it delivers consistent temperature and humidity control, safeguarding the integrity of your wines over time.
This system uses a two-module setup — an evaporator (fan/coil) inside the cellar and a condenser placed remotely — connected via copper tubing and low-voltage wiring. The split-system design provides installation flexibility, allowing the condenser to be placed up to 50 feet away, reducing noise and heat intrusion into the cellar space. The included digital control system gives you precise control over cooling and airflow, making it ideal for serious collectors who want reliable, professional-grade conditions.
Built for durability and ease of maintenance, the WKSL 4000 features a sturdy metal cabinet that blends discreetly with cellar interiors and can be mounted flush to the wall. Its automatic humidity control helps prevent cork and label deterioration, while dampened mounts minimize vibration to preserve sediment integrity. The system’s comprehensive quality and craftsmanship are backed by Breezaire’s warranty coverage — giving collectors peace of mind that their investment in storage climate is protected.
For anyone building or upgrading a wine cellar and looking for a long-lasting, high-performance cooling solution, the Breezaire WKSL 4000 strikes a balance between professional-grade climate control and discreet, cellar-friendly operation.
