WhisperKOOL Slimline LS Cooling Unit Review

We are proud to introduce our new and improved Slimline LS with smart ECM condenser fans. Utilizing the best available technology, we have created this new design with enhanced features which offer powerful performance, quiet operation and longevity to protect your investment in fine wine! 

NOTE: WhisperKOOL Slimline LS is a direct replacement for WhisperKOOL Slimline 2500 and WhisperKOOL Slimline 3300.

We are excited to announce the newest and first model from the Luxury Series of WhisperKOOL Wine Cellar Cooling Units, the WhisperKOOL Slimline LS Cooling Unit.

The WhisperKOOL Slimline LS is a through-the-wall cellar wine cooling unit (self-contained), specifically designed to fit into the often unused space between the cellar door and the ceiling. This allows the unit to fit snugly above the cellar door, providing efficient cooling without taking up much space and having a low visual profile. WhisperKOOL Slimline LS Wine Cooler Unit can accommodate approximately 300 cu.ft. (low fan speed) and 650 cu.ft. (medium fan speed) cellar size. It’s one of the quietest wine cellar cooling units we have!

This wine room cooling unit can cool at two capacities with the flip of a switch, and features advanced technologies such as a smart condenser ECM fan for efficient heat dissipation, centrifugal blowers for a significantly quieter operation, and adjustable medium or low speed, larger coils for larger system capacity, and an improved condensate management system. To make maintenance and adjustments even more convenient, the controller has been relocated to the condenser side of the unit.

We provide an upgrade option of UV-C Lighting System to protect your WhisperKOOL Wine Cooling Systems from bacteria and mold growth. We also offer an interchangeable decorative grille that can be used to personalize the appearance of your luxury system.

*NOTE: WhisperKOOL wine cooling units work best in a well-insulated and sealed room with a proper vapor barrier. Every wine cellar is different and has its own cooling needs. It's important to perform heat load calculations before choosing a cooling system for wine cellars.


1704 - 2413

The BTU/h value range shown here is an estimate and not a guarantee. There may be instances where a cellar design requires a larger unit due to variables not included in the calculation. These variables can be building materials (such as glass, stone, concrete, etc.) that do not provide enough insulation to maintain the ideal wine cellar environment.

We recommend purchasing a unit with a higher capacity to compensate for these unforeseen variables. Choosing an undersized unit may result in premature failure and may not be able to achieve your desired wine cellar temperature.


WhisperKOOL Accessories (Optional)

You may add WhisperKOOL replacement parts and accessories to enhance the performance and longevity of your wine cooling systems. These add-ons include items that upgrade and protect the system. Check out the other WhisperKOOL Parts & Accessories.

UV-C Light Technology

Adding UV-C Light Technology to WhisperKOOL wine cellar coolers enhances the overall indoor air quality inside the wine cellar and improves the system's performance. The UV-C light bulb inside the cooling system will protect it from mold and bacterial growth, extending the lifespan of the unit.

Great Store!

We purchase a wine cellar in other store. We put the cooling unit in our wine cellar room. However, it didn't perform as well as we wanted to so we decided to look for an alternative. We discovered this store and placed a cooling unit. It works really well for us!

Satisfied with my Slimline LS Cooling Unit

I am very happy with my purchase. I would recommend Whisperkool to everyone who is looking to keep their wine cellar at a certain temperature.

Iris P.
Durable Unit!

I am very happy we bought this Whisperkool Wine Cooling Unit. We are even considering buying another one for our restaurant. Thanks again Wine Coolers Empire.


Great unit


My husband installed it last week. It was hard to carry it and we still needed help installing it. Good thing the delivery guy was very nice. He helped us carrying it inside and to position it inside our wine cellar. I know he wasn't supposed to help us but he did. We really appreciate it.

Shari D. Royse

Very easy to install. The instructions are straight forward. Lisa was very kind and knowledgeable. She also answered all my queries very patiently
