Extreme Series


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.
