Breezaire WKL 4000 Wine Cellar Cooling Unit

The Breezaire WKL 4000 is a self-contained, through-the-wall wine cellar cooling system designed for properly insulated wine cellars up to 1,000 cubic feet. With 4,000 BTU of cooling output, it is designed for medium-to-large residential wine cellars where a self-contained cooling system is preferred over a split system.

The WKL 4000 provides an adjustable temperature range of 48–63°F and features automatic humidity control. Electronic controls and an LED digital display allow the cellar temperature to be monitored and adjusted, while the automatic defrost system helps manage frost accumulation during operation.

Its through-the-wall installation places the cooling unit directly through the cellar wall, with the standard configuration exhausting hot air through the rear of the unit. This configuration eliminates the need for a separate remote condenser and refrigerant-line installation. Optional factory modifications are available for applications requiring alternate exhaust or power-cord routing.

The WKL 4000 measures 19.75" H × 14.25" W × 21.63" D, weighs 81 lbs., and operates on 115V / 60Hz / 7A. Proper cellar insulation, vapor-barrier construction, sealed penetrations, and adequate ventilation in the exhaust area are important for proper operation.

Cooling System Specifications

Key Features

• Up to 1,000 Cu. Ft. Cellar Capacity: Designed for properly insulated and sealed wine cellars up to approximately 1,000 cubic feet.
• 4,000 BTU Cooling Output: Provides the cooling capacity specified for the WKL 4000's intended wine cellar applications.
• Self-Contained Design: Combines the cooling components in a single unit, eliminating the need for a separate remote condenser.
• Through-the-Wall Installation: Installs through the cellar wall and exhausts heat into the adjacent space, providing a self-contained installation configuration.
• 48–63°F Temperature Range: Provides an adjustable operating range for controlling the temperature of the wine cellar.
• Automatic Humidity Control: Automatically manages cellar humidity to support the environmental requirements of wine storage.
• Electronic Controls and LED Display: Allows the cellar temperature to be monitored and adjusted through the electronic control system.
• Automatic Defrost: Automatically manages frost accumulation during normal operation.
• Low-Vibration Design: Vibration-dampening components help reduce vibration transfer during wine storage.
• Optional Bottle Probe: A compatible bottle probe can monitor the temperature inside a wine bottle rather than only measuring the surrounding cellar air.

Installation Requirements

Cellar Size Guidance

Actual cooling requirements depend on factors including insulation quality, vapor-barrier construction, ceiling height, ambient temperature, glass exposure, and door construction. The exhaust area should also provide sufficient space for heat dissipation.

Optional Factory Modifications

Important: Factory modifications are special-order configurations and may add production time. Modified units are non-returnable and cannot be canceled once manufactured.

Optional Bottle Probe

The optional Breezaire Bottle Probe monitors the temperature of the liquid inside a wine bottle rather than only measuring the surrounding air. The bottle probe is compatible with Breezaire WKL, WKE, and WKC series cooling units.

Replacement Compatibility

Warranty

The Breezaire WKL 4000 includes a 1-year labor warranty and 5-year parts warranty according to the manufacturer's listed specifications.
