WhisperKOOL Slimline 2500 Wine Cellar Cooling Unit


Slimline 2500 self contained wine cellar cooling unit by WhisperKOOL


The Slimline series is great for smaller wine cellar spaces and ideal for over the door installation. This unit will solve your wine cellar refrigeration and allow you to maintain maximum bottle count in smaller spaces by utilizing normally unused space. 
  • CELLARS UP TO 350 Cu. Ft. (with proper insulation and vapor barrier)

The Slimline is WhisperKOOL’s quietest interior venting self contained unit available. Developed to mount in a living area and designed to fit into the often unused space between the cellar door and ceiling, giving the collector maximum storage capacity.

The system is equipped with WhisperKOOL’s Platinum Series controller utilizing Advanced System Protection Technology. This features a series of strategically placed monitoring probes, which insure efficient performance and long cooling unit life.

With efficiency in mind, the Slimline uses less power than most traditional units while having the ability to cool cellars up to 350 cubic feet.

BTUh Rating:
There are circumstances in which a cellar design may require a larger unit due to some existing design restrictions.

There are several factors such as glass, stone, concrete, etc. which will seem adequate but do not offer the insulation capacity required to maintain the optimum environment.

We recommend purchasing a unit with a larger capacity to compensate for the design limitations. Please utilizing our Cellar Wizard in order to ensure you are selecting the proper cooling unit for your application.

Under sized cooling units can lead to pre-mature failure and/or prevent the system from reaching the desired set temperature. As a result they are not covered under warranty.

Great unit for our first wine cellar

Many thanks to Wine Coolers Plus customer support discussing the options and helping us select the right unit for our project. This was our first wine cellar and in a small space under our stairs, this over the door unit ended up being perfect for the space and keeping our cellar at the perfect temp and humidity. Luckily our location was an easy conversion inside the home, the unit is quiet and we don't even notice the white noise at this point.
