WhisperKOOL SC PRO 4000 Self-Contained


This unit will solve your wine cellar cooling needs if you have a medium sized cellar with proper construction (insulation, vapor barrier). If you need a unit that's easy to install and straight forward operation, you are in the right place.  

  • CELLARS UP TO 1000 Cu. Ft.(when properly insulated and vapor barrier installed)
The SC PRO Series embodies the latest and greatest system design technologies in an all-new housing design. Developed upon feedback directly from customers and installers, the unit incorporates a variety of high-end components at an affordable price point. By combining powerful airflow with quiet operation technology, the SC PRO is unrivaled when it comes to efficiently cooling small to mid-sized wine cellars. 

What separates the original SC Series from the SC PRO Series? The SC PRO comes complete with a new, blower fan system that optimizes performance while operating at a significantly lower noise level. It also reintroduces a condensate management system, which effectively evaporates up to 3oz. of water an hour. This management system renders the drain line as an additional safeguard rather than a definite need. 

The SC PRO Series will be a direct replacement for the SC Series, and its predecessor, one of the most well-known cellar cooling units, the XLT.

    The BTU/h value shown here is a theoretical number. There are often circumstances under which a cellar design may require a larger unit due to variables not accounted for in the formula. For example, these variables could be building materials (such as glass, stone, concrete, etc.) which do not offer the insulation capacity required to maintain the optimal cellar environment. We recommend purchasing a unit with a larger capacity to compensate for these unaccounted-for variables. An undersized unit can lead to premature failure and will most likely prevent the cellar from reaching your desired temperature.

      Cellar Size: Approx. 1000 cu. ft. when cellar is fully insulated and sealed with proper vapor barrier (each wine cellar is unique and has specific cooling requirements; heat load calculations should always be performed prior to selecting a cooling unit)

    Upgraded and happy

    I replaced my cooling unit after about 8 years, this new model fit right in the old slot and works great and very subtle hum when running. When the delivery truck arrived the unit was upside down on the truck, I was a bit worried about this, I let it sit 24 hours in the upright position before turning it on. I would have gone 5 stars if the delivery had not been concerning.

    So far so good, quiet and we are pleased

    Just got the new model, it was a bit of a challenge installing by myself but would have been no problem if I had a helper. The unit is very quiet and keeping my collection cold. Wine Cooler Plus was very helpful recommending the size of unit needed for our space.

    Great value for the money

    Our first wine cellar, easy to install, we even added the ducting kit ourselves with no major meltdowns.

    Happy aging wine in the cellar

    We Spent a bit of ime researching before deciding to make this purchase. Packaging was excellent, unit is very quiet and works as expected.

    Happy all around

    Wine Cooler Plus team helped us with the unit sizing, we already new based on friends recommendation we wanted to the Whispercool brand. Delivered ontime but we were missing setup manual, easily remedied by downloding from the wedsite.
