PLEASE NOTE: You will need an Extreme cooling system if the ambient temperature on the condenser side will exceed 85°F.

SKU: U-WKSC4000-115-PRO Categories: ,


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 4000 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 4000 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.

3D Tour (Application Example)



The BTU/h value range 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 Wizard

For more specific calculations, we have a tool which accounts for these variables. Please utilize this tool in order to ensure you are selecting the proper cooling unit for your application. Our tool is called the Cellar Wizard.

Note: The systems do not include a line set.

  1. Emily B

    I bought this unit after having the XLT for many years. I wanted an upgrade that was easy to install and manage in the same aspects the former was, without an outrageous price or hassle. After reaching out to the customer service team and letting them know exactly what I was looking for, they suggested this SC PRO 4000 that was a modernized option to the XLT. I was able to install it myself into my existing cellar and away it went! Let’s see how long this one goes

  2. Robert Mezza

    The new Whisperkool SC 4000 Pro arrived in less than a week and in perfect condition. I can’t believe how much quieter is is than the XLT4200 that it replaced.
