The D050 wine cellar cooling system is a self-contained, ducted wine cellar cooling system for medium-sized residential and commercial applications. The wine cellar cooling calculator can help determine if the D050 will be suitable for your wine cellar. The D050 wine cooler is also suggested for smaller cellars containing large amounts of glass. Contractor installation is recommended. The maximum capacity is 6,320 BTU/h (1.85 Kilowatts). The D050 system is available in a water-cooled configuration.

[The D050 is a 60Hz system, which is standard in the majority of North and South America; if you need a comparable 50Hz system (used in most of Europe, Asia, Africa, & Australia) see the WG75 wine cellar cooling unit. Verify your country’s line frequency].

Options and accessories for D050 cooling systems are shown below. The Electric Heat option is a factory-mounted heater which protects your cellar from cold ambient temperatures. Duct collars give owners the option of adding additional ducting to and from their Wine Guardian unit.

The ducted split wine cellar cooling system has several different options available.  The available electric heater is a factory-mounted option that will protect your wine cellar from cold ambient temperatures. A standalone humidifier is a necessary addition if the wine cellar consistently sees low relative humidity (RH) levels. Lastly, Wine Guardian’s remote monitoring and sensing system allows the user to place up to three (3) remote sensors in the wine cellar to monitor average cellar conditions at different locations in the cellar (near the ceiling, near the floor, etc). This information is continuously relayed to the cooling unit and to the remote interface controller.
