Product Description

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.


NewBTUh Rating:
There are circumstances in which a cellar design may require a larger unit due to existing restrictions. Building materials such as glass, stone, concrete, etc. 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 design limitations. * Please utilize our Cellar Wizard in order to ensure you are selecting the proper cooling unit for your application. Undersized cooling units can lead to premature failure and/or prevent the system from reaching the desired set temperature. As a result, they are not covered under warranty.

  1. Great Value ~ Feature Rich 5 Star Review

    Posted by on Nov 10th 2010

    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.
