Share this product


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.

BTU/h Rating


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.

  1. Albert C

    This unit looks great in my cellar. I was not a fan of the bronze on my XLT. Slid this through the same hole and had it running in minutes. Sounds great and cools even better

  2. Gene Closson

    I bought an SC unit in 2014. For the past 5 years, one of the biggest thorns in my side has been checking the bucket that the excess water drains in to. I upgraded to the SC Pro in hopes of not having to do this anymore. We’ll see…

    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.

  4. 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
