WhisperKOOL SC PRO 4000 Wine Cellar Cooling Unit Review

Searching for a wine cooler unit that's easy to set up? WhisperKOOL SC PRO 4000 Wine Cooling Unit is the perfect solution for you!

NOTE: WhisperKOOL SC PRO 4000 is a direct replacement for WhisperKOOL SC 4000i and its predecessor, one of the most well-known cellar cooling units, the WhisperKOOL XLT 4200‎. 

The WhisperKOOL SC PRO 4000 Wine Cellar Cooling System features the most advanced technologies and a new housing design. Developed and enhanced based on customer and installer feedback, and includes high-end components at an affordable price. This WhisperKOOL wine cellar cooling unit combines powerful airflow with quiet operation technology, making it the best option for efficiently cooling small wine cellars to medium-sized wine cellars.

SC PRO Series - WhisperKOOL Wine Cellar Cooling Systems are easy-to-install wine cellar cooling units (self-contained) that do not require a professional HVAC-R technician for installation.

The SC PRO series offers additional features that can be added on, such as a UV-C Lighting System which helps eliminate mold and bacterial growth in the cooling system, a Condenser Ducting Kit that allows for the safe and efficient venting of the unit, and an Exterior Grille to protect the exhaust side of the system. These options give you the flexibility to customize the unit to meet your specific needs and preferences

Available in WhisperKOOL SC PRO 2000 for 300 cu.ft. wine cellar, WhisperKOOL SC PRO 3000 for 650 cu.ft. wine cellar, and WhisperKOOL SC PRO 8000 for 1500 cu.ft. wine cellar.

What makes the SC PRO Series different from the SC Series?

WhisperKOOL SC PRO 2000 Wine Cellar Cooling Unit - WhisperKOOL | Wine Coolers Empire - Trusted Dealer

The WhisperKOOL SC PRO 4000 has a new, improved fan system that enhances performance and operates at a much lower noise level. Additionally, it includes a smart refrigerant metering and condensate management system that can evaporate up to 3oz. of water per hour, reducing the need for a drain line as an additional safety measure.

    The digital thermostat found on the front of the device comes with a feature called Advanced System Protection which includes alarms to notify you if certain conditions are not met.
    Digital Controller - WhisperKOOL | Wine Coolers Empire - Trusted Dealer
    WhisperKOOL wine cooling units accurately measure the temperature of wine in the cellar through the use of WhisperKOOL bottle probe or liquid temperature measuring probe. This method of measuring the temperature of a liquid is more precise and provides a more accurate reflection of the temperature of the wines stored in the cellar compared to measuring the temperature of the air in the cellar.
    Bottle Probe - WhisperKOOL | Wine Coolers Empire - Trusted Dealer
    The new SC PRO WhisperKOOL Cooling Units feature a revised fan system that provides powerful and direct airflow. This new fan design allows for even quieter operation and is meant to efficiently distribute conditioned air throughout the wine room.

    A new advanced condensate management system has been added to this WhisperKOOL Wine Cooling System, which can efficiently evaporate up to 3 ounces of condensate per hour of operation. This management system makes the drain line a secondary precautionary measure rather than a necessity.

*NOTE: A wine cellar cooling unit works best in a well-insulated and sealed room with a proper vapor barrier. Every wine cellar is different and has its own cooling needs. It's important to perform heat load calculations before choosing a cooling system for wine cellars.





The BTU/h value range shown here is an estimate and not a guarantee. There may be instances where a cellar design requires a larger unit due to variables not included in the calculation. These variables can be building materials (such as glass, stone, concrete, etc.) that do not provide enough insulation to maintain the ideal wine cellar environment.

We recommend purchasing a unit with a higher capacity to compensate for these unforeseen variables. Choosing an undersized unit may result in premature failure and may not be able to achieve your desired wine cellar temperature.

    SC PRO 4000

    The purchase from Wine Coolers Empire was positive and the unit shipped fairly fast. Previously I had Cellar Cool which did not last very long. I really can not review my new unit as it is only a few weeks old. Ask me to review the unit after a few years.

    Joe Pellicer
    It gets the job done.

    My SC PRO 4000 is quietly performing exactly as expected. My last Whisperkool 4200 lasted 25 years. Pretty damn impressive. If my liver lasts another 25 years I’ll be very, very happy!

    WhisperKOOL SC PRO 4000

    When my 25+ year old wine cooler failed, I replaced it with the WhisperKOOL SC PRO 4000. The package arrived in excellent condition and installation was a breeze. Fit perfectly into the same opening as the old one and all is well.
