The SCs are our easiest-to-install self-contained cooling units. The SC Series offers a wide range of cooling capacities at an economical price. The five units in the series can cool cellars between 300 and 2,000 cubic feet (given adequate cellar construction and a properly installed vapor barrier). They do not require an HVAC-R technician to install.


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.

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.

    Replaces our 17 year old WhisperKOOL 3000

    This new model has one improvement over the old one in that it’s thermostat is digital.We haven’t had the new one quite 2 months yet, but it is performing just fine. The old one needed to be sent to a factory repair center about half way through its life. That was frustrating because they had the unit for 6 weeks to repair a leak in the refrigerant lines. We’re keeping our fingers crossed for this new model. Basically, WhisperKOOL is about the only game in town for small wine cellar climate control. We were pleased that the dimensions of the new model were identical to the old one’s, so we did not need to modify our cellar wall opening to have it fit properly.

    I had the XLT model for the last 10 years and it worked well. It had simply worn out and I needed to get a new one. Did not know they changed the model, so was surprised to see the new design. I purchased the SC3000i and it fit perfectly in to the old space. It’s quieter and looks better than the XLT.

    Quiet and Efficient Performance

    I bought this unit to replace a commercial assemblage of components that had failed repeatedly. The wine room is 8X10X4, for roughly 320 cu. ft. The unit works as advertised, cooling the room to less than 55 degrees in the startup but bringing the bottle temperature to 55 degrees exactly. As it stabilized, the room temperature is gradually coming up to the same as bottle temperature (55). I had it professionally installed, and though not necessary, it worked out well for my installation. I recommend spending the extra money for your local refrigeration company to install it. Very pleased with performance, looks and quiet. My neighbors and my wife both appreciate the last element.

    Fit in the hole the last one came out of. Improved flange made it easier than the previous unit to install. Works like a charm.

  5. Stephen Wells

    Easy install. Has worked great so far. It is quieter than the previous model

  6. Amazon Customer

    Much improved from the older version, but fits perfectly in the same opening. Works as advertised.

  7. Amazon Customer

    So far, working perfectly.

    Needs Better Drain

    Great replacement for the XLT except it no longer has a condensation burner, forcing the need to run a hose down the outside of the cellar. It should at least offer an option to drain inside the cellar to allow flexible installation. It’s kicking out about a cup and a half of water a day in a dry climate.

    I designed and built a room for my hobby. I choose a WhisperKool unit to keep it at an appropriate temperature. After two flawless years it developed an operational error. With a call to their support center it was quickly arranged to return and prepare with the only cost for shipping. Thanks to WhisperKool.
