WhisperKOOL Slimline 2500 Wine Cellar Cooling Unit Review

WhisperKOOL Slimline 2500 Wine Cellar Cooling Unit is Discontinued. Replaced by WhisperKOOL Slimline LS Cooling Unit.

PLEASE NOTE: We will be phasing out the 9000 and 12000 110V condensers on 10/01/2023 or sooner. We will continue to support controllers through the two-year warranty period. All other replacement part requests will be directed to Copeland.

The WhisperKOOL Slimline 2500 Wine Cellar Cooling Unit is one of the quietest and most compact through-the-wall wine cellar cooling units (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.

The system has a WhisperKOOL Platinum Series controller with Advanced System Protection Technology. This ensures effective performance and a long cooling unit lifespan through several carefully placed monitoring probes. The Slimline is energy-efficient and can cool wine cellars up to 350 cubic feet while using less power than traditional units.

The most economical and easiest to install are through-the-wall wine cellar cooling units(self-contained). They are designed to mount between the studs of an existing wall and do not need to be installed by a licensed HVACR technician. Cool air is blown into the cellar from one end of the system, while the other end exhausts heat into an adjacent room.

*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.





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.
