The Breezair WKSL 4000 is the advanced system of choice for standard applications ranging from under 100 to 2000 cubic feet. Breezair WKSL 4000 are compact, self-contained units. Their performance speaks for itself. This series is equipped with the BREEZAIRE’s affordable Sentry III control system. This system offers more features that others offer in their higher-grade models.

Units are shipped from the factory fully charged and ready for use when mounted in a wall and connected to 115 AC volt source.


  • Large, easy to read, cool green LED display
  • Accurate, easy to adjust temperature set points with continuous display of cabinet temperature.
  • Power outage protection.
  • Blocked airflow protection, which shuts down unit and protects wine in case of high temperatures caused by condenser blockage or fan failure.
  • Controls temperature by enclosure (cellar) air sensors or optional bottle probe.


By the nature of their operation, wine cabinet cooler will maintain a stable humidity level, lower than the relative ambient humidity. In situations where the ambient humidity is high, the cooling unit will lower the humidity to desirable storage levels.

In situations where the ambient relative humidity is very low, the desired enclosure relative humidity may not be achieved without adding moisture. To add moisture to the enclosure only use slow, natural evaporation from a small porous water container. Do not use a humidifier.


This Breezair WKSL 4000 is made to cool 25 degrees less than the ambient temperature of the venting side of the unit. In some cases, improper placement or installation may cause the unit’s performance to be degraded. The condensing unit must have a constant supply of fresh air, less than 85 degrees F.

If the condensing unit is located in a confined area with poor ventilation, the unit will not be able to reject the heat it is removing from the enclosure and a malfunctioning unit will be suspected, even though the unit is mechanically sound. Call us to discuss your installation concerns.


The ideal temperature for storing and aging wine is between 50° and 60° Fahrenheit. Each BREEZAIRE system includes an adjustable thermostat that makes it possible for the user to precisely control the conditions in the wine cellar.

When initially bringing the temperature down to the desired level and in maintaining the target temperature, the system produces a gentle stream of cool air – never a blast of cold air that could subject the wine to abrupt temperature changes.


Humidity must be present in the wine cellar to prevent cork and label deterioration. The gentle cooling action of the BREEZAIRE system maintains the relative humidity in the 50% to 75% range, eliminating excess moisture but never allowing the air to become dry enough to create an undesirable condition. (Additional moisture may be required in extreme dry climates.)


All Breezair WKSL 4000 systems are engineered to be vibration free, hand assembled, and tested to ensure that they meet the most exacting standards. The elimination of vibration levels that may be undetectable to the owner results in wines that have greater clarity and brilliance.


Breezair WKSL 4000 systems perform their task quietly and unobtrusively to preserve the atmosphere of isolation from the outside world that makes a visit to a wine cellar an unique experience.


An attractive metal cabinet that blends in with the d1/2©cor of your cellar area and can be flush mounted to any wall.


BREEZAIRE’s most popular systems are completely self-contained modules that are simply mounted in a wall and connected to a standard 115V AC source. No plumbing, complicated wiring or special procedures including the on-site installation of refrigerant are required.


All BREEZAIRE systems are designed to deliver superior performance. Constructed using only the highest quality components, and hand assembly by skilled craftsmen in BREEZAIRE’s U.S. production facilities.


Owners enjoy the security of warranty coverage that reflects BREEZAIRE’s high standards.
