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.
