The unique difference between the CellarCool systems and traditional air conditioner is the maintenance of well-conditioned humidity. Traditional air conditioning units are designed to cool quickly: as a result, humidity is removed below acceptable levels which can lead to dried out corks and oxidized wine. CellarCool achieves the optimal results by cooling the air slowly, cycling down the temperature while maintaining humidity between 50% and 70% in properly prepared wine cellars. CellarCool offers a collection of quiet, commercial grade wine cooling systems that provide exceptional features, warranty, and service.

If you are new to wine cooling, or just want to learn more about the system you have,
CellarCool recommends reviewing these topics.

  1. Consult a wine cellar professional
    Every wine cellar has a unique set of challenges that need to be identified during construction. A cellar professional will help you to address all of the variables that are associated with creating the most efficient cellar environment.
  2. Cooling units make noise
    Our units are designed to be as efficient as possible, but all cooling units generate noise from the compressor and airflow through the fans. You need to consider the location of the cellar and the cooling unit exhaust, particularly when installing a self-contained unit. If noise in these areas is not acceptable, consider a split or ducted system.
  3. Cooling units run the majority of the time
    The amount of time that any cooling system will operate is dependent on the cellar design, the size of the unit, and the ventilation environment. Because your cellar is comparable to a walk-in refrigerator, the unit will operate as needed 24 hours a day, 7 days a week, 365 days a year. Your unit will run 50% to 70% of the time on average in order to maintain the correct temperature.
  4. Cooling units generate a large amount of heat
    As the unit cools the cellar by absorbing heat from the air, the condenser must reject the heat created during operation. It is critically important that the heat be dissipated effectively from the unit in order to maximize performance. Failure to provide proper ventilation will compromise the wine cellar environment and shorten the lifespan of the cooling unit.
  5. Temperature differential
    This critical specification for a cooling unit plays a major role in its ability to cool your cellar to the desired 55°F for wine storage. The temperature differential is the difference a unit can cool from the area it is exhausting into. For example, a unit with a 30°F temperature differential will only be able to cool a cellar down to 60°F if the exhaust environment is 90°F.
  6. Insulation affects cooling unit performance
    The more insulation you have, the more efficient your cellar will be. Without insulation, your cooling unit will work harder to maintain the proper temperature. This results in a shorter lifespan for the unit. Note: concrete walls are not appropriate for a wine cellar, as they absorb cooling. Your cellar requires framed walls with insulation.
  7. Install a vapor barrier
    Just as you need insulation to help regulate cellar temperature, you must install a vapor barrier to help your cooling unit maintain the proper humidity. Lack of a vapor barrier will result in improper humidity and will compromise the wine storage environment. Consult your local regulations and building ordinances for proper vapor barrier installation.
  8. Redundant cooling systems for high value collections
    If cooling failure occurs for any reason, a redundant system will keep your cellar environment from being compromised. Redundancy can be a second cooling unit, or the home A/C system can be used. A backup generator is a good idea in case of power failure. You should have some kind of contingency plan in place in case of electrical or mechanical failure in the cellar.
  9. Temperature
    The wine cellar temperature should stay a constant 55 degrees. The cool temperature helps slow down the aging process of the wine.
  10. The advantage of air sensing temperature probes
    Air sensing temperature probes are placed near the air return of the evaporator coil. The probe is attached to the thermostat and provides a measurement of the hottest air in the room. The cooling system can regain normal temperature levels more swiftly with an air sensing probe than with a liquid probe due to air registering temperature change at a faster rate than liquid.
  11. Vibration
    Vibrations may increase the chemical breakdown in your wines. Make sure to store your wine far away from vibration.
  12. Humidity
    Humidity should stay between 50 - 70%. Lower humidity may dry out corks. Higher humidity could damage labels and promote the growth of mold. In addition, it is good to keep bottles on their sides to prevent the bottle corks from drying out.
  13. Light
    Long periods of sunlight and florescent lights can have a harmful affect on wine. Do not keep wine cellar lights on for extensive amounts of time.
