SKU: U-WKSL-LS-115-6- Categories: ,


We are happy to announce the first unit in our new luxury series (LS). The new Self Contained Slimline LS has evolved into a unit that can cool at two capacities at the flip of a switch. We have added smart condenser ECM fan technology for efficient heat dispersion, centrifugal blowers, which are significantly quieter and can also be set at a medium or low speed, larger coils for greater system capacity, and an improved condensate management system. The controller has been moved to the condenser side of the unit for easier access.


We offer a UV-C Lighting System upgrade to protect your unit from mold and an interchangeable decorative grille to customize the look of your luxury system.


The Self Contained Slimline LS is one of our quietest and most compact self-contained cooling units. Slimline units were designed to be mounted in a living area and can be placed in the often-unused space between the cellar door and ceiling.The Slimline fits snugly above your cellar door, out of the way, providing efficient cooling and a low sight profile.

3D Tour (Application Example)


1704 – 2413

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.

    We converted a pantry into a cellar and used the Slimline 2500 over the glass door we installed. I was initially on the fence since I was concerned about noise and heat venting into the space (a butlers pantry between our kitchen and dining room) but it worked out great! As others have said, the noise of the unit is similar to a running dishwasher when it cycles on. My cellar is well insulated and we keep our home on the cooler side, so most of the year it doesn’t have to run for long periods. As for the heat – this has not been a problem at all. My only note – sometimes it will make an odd hissing noise – but its just every so often. The one note – this thing is heavy – you will need two strong individuals to hoist it over a door (especially in a confined cellar like mine). It’s been many months installed and I am 100% happy with this purchase – if your on the fence like I was – take the plunge and start cooling that wine!

    We changed a closet/under stair area in our vacation home into a wine cellar. This small unit fit perfectly and works great.

    Works great for my cellar

    I have owned a WhisperKOOL 7000 split system for the past three years. My wine collection is about 1500 bottles. The cellar has maintained a consistant 55 degrees all the time. I imagine the cooling unit could cool a much larger cellar than mine considering that it runs less than 50% of the time. Noise is not a factor as the evaporator unit in my cellar is very quiet, the condenser is outside in the side yard. The only thing i would change is the installation location. I should have mounted the evaporator above the doorway so it would not be seen. other than that, i am very satisfied with this product.

    WhisperKool’s Slimline 2500 unit is the heart of my very first wine cellar and it has been a great success. At approx. 500 bottles, the unit has masterfully controlled both temperature and humidity, effortlessly. We recently experienced some very unseasonably warm weather in our area, and the unit handled it very well. The sound produced by the unit is amazingly quiet, and has quickly faded into our memory as would white-noise or the hum of a high-end dishwasher. The volume is almost undetectable from the next room and definitely cannot be heard from the upstairs bedrooms. I have also been very pleased with the unit’s ability to control the temperature of the cellar from liquid vs. air temp. This has really helped the unit manage overall cellar temp accurately without a challenge from opening & closing of the cellar door. The features are beyond my original expectations, and I highly recommend the Slimline unit to fellow wine enthusiasts. You will not be disappointed.

    Over door wine cellar cooler

    I really like this wine cellar cooler. It is located over the entrance door. That locatation is the best. #1 the cooler is out of the way dose not take away from your wine storage. #2 The cooling effect is great. When you open the door to enter your cellar and get a wine bottle. #3 After closing the door. The cooling is started where the cool air has left the cellar. Works great and super quiet.
