The DS025 split wine cellar air conditioner with ductable fan-coil is ideal for small residential and commercial applications. The DS025 has an application range dependent upon use and room construction. Always use the wine cellar cooling calculator to correctly size a unit for your application. Contractor installation is required. Max capacity of 3,400 BTU/H (1.055 Kilowatt).

[The DS025 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 WGS40 wine cellar cooling unit. Verify your country’s line frequency.]

Option Bundles:

All Wine Temperatures Bundle: For extended wine-cellar temperature ranges (on the evaporator section).

The All Wine Temperatures bundle is an optional bundle for the DS025. It is perfect for small or mid-sized wine rooms and multiple cabinet applications in which serving temperature cooling is preferred. It also contains integral electric heater coil and controls to protect your wine cellar from low temperature conditions. *Patent Pending

Extreme Climate Protection Bundle: Unit protection in extreme climate conditions (on the condenser section).

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.
