Wine Guardian Fully Ducted Self-Contained – D025 1/4-Ton Water Cooled (Sentinel Series)


This unit is a water-cooled version of the standard Wine Guardian D025 wine cellar cooling unit. The Water-Cooled D025WC unit requires a year-round water source.  The D025WC unit comes as the base model (standard cooling unit only) or you can select to the AWT bundle below. *Patent Pending

SKU: 99H0254-20 Category:
The water-cooled D025WC is the smallest Wine Guardian packaged ducted system that includes a factory-configured integral water-cooled condensing coil and water-regulating valve. This wine cellar cooling system is ideal for geothermal, cooling tower and lake water applications. The unit does not require warm condenser air connections, making it an excellent solution when warm-condenser-air venting is not possible. These units provide up to 3,300 BTU/H of capacity.

Additionally, the D025 wine cellar cooling unit comes with many options and accessories. The All Wine Temperatures bundle contains both a factory-mounted heater to protect your cellar from low room temperatures and extended controls to adjust your wine room or wine display to serving temperatures.

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.
