BTUh 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 consult with one of our professionals to ensure you are selecting the proper cooling unit for your application. We are able to give you a proper BTU estimate, based on your construction parameters. 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.

Cellar Wizard

For more specific calculations, we have a tool which accounts for these variables. Please utilize this tool in order to ensure you are selecting the proper cooling unit for your application. Our tool is called the Cellar Wizard.
