The D025 is a ducted wine cellar cooling unit for small residential and commercial wine cellars. The D025 unit is a self-contained, fully ductable cooling unit and as is a step up from the TTW018. If the cellar is sized for the TTW018 and contains a lot of glass, moving to the D025 is recommended. Contractor installation is recommended. The maximum capacity is 3,300 BTU/h (0.97 Kilowatts). Additionally, the D025 wine cellar cooling unit comes with many options and accessories.  The Low Ambient and High Ambient options protect your wine collection from low (below 40°F) and elevated (100°-120°F) ambient temperatures, respectively. The Electric Heat option is a factory-mounted heater which is also available to protect your cellar from low ambient temperatures.  Moniteur Du Vin is a wine cellar tracking system, which monitors your wine cellar and immediately notifies you of any deviations to your pre-set safe ranges. 

Versatile and self-contained, Wine Guardian ducted wine cooling systems offer maximum flexibility in design and installation. They also provide cooling for any sized area, whether you are storing in a residential, restaurant, or commercial wine cellar. With ducted wine conditioning systems, a grille on the inside wall is connected by insulated flexible ductwork to a self-contained unit outside the wine cellar that contains the evaporator, fans, compressor, condenser, and controls. This system can be placed in an indoor location outside the cellar resulting in a quiet cellar with no obtrusive equipment taking up valuable racking space. Ducted wine room systems are ideal for larger private or commercial wine cellars. Available in water-cooled configurations.  Made in USA.

BTU/h Rating


The BTU/h value shown here is a theoretical number. There are often circumstances under which a cellar design may require a larger unit due to variables not accounted for in the formula. For example, these variables could be building materials (such as glass, stone, concrete, etc.) which 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 these unaccounted-for variables. An undersized unit can lead to premature failure and will most likely prevent the cellar from reaching your desired temperature. 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.
