Product Description

The next generation in specialty cooling systems. The SC Series embodies the latest and greatest system design technologies in an all-new housing design. Developed upon feedback directly from customers and installers, the unit incorporates a variety of high end componentry at an affordable price point. The SC Series is a direct replacement for one of the most well known cellar cooling units, the XLT. Just like the series it replaces, the units come in 5 models that effectively cool a 300 to 2000 cu. ft. properly insulated environment. Designed for simple through-the-wall installation, the unit fits between standard wall studs and a single piece mounting bracket eliminates the need for a support shelf. The SC has a 30°F temperature differential. In order to keep your cellar at 55°F, the area the unit exhausts into should not exceed 85°F. This makes interior installation ideal for SC series units.


Standard Features:

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.

    The previous Whisperkool system in this house lasted 20 years with absolutely no maintenance. I was so pleased that the new Whispercool system was the exact same size as the previous product from 20 years ago. I removed the old system and replaced with the new system in about an hour with no modifications to the wall. Working great!!!

  4. Really like the Bottle Probe! 5 Star Review

    I’ve had the SC 4000i cooling system for a few months now and the wine cellar is full. I like how it monitors the liquid temp. The cellar has steadily maintained the temperature at 55 degrees, so I’ve been happy so far.
