WhisperKOOL SC PRO 4000 Self-Contained

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)

    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.
