Wine Guardian D050 Ducted Wine Cellar Cooling System
Sentinel Series Wine Cellar Cooling Unit
The Wine Guardian D050 Sentinel Series is a self-contained ducted wine cellar cooling system designed for wine cellars between 650 and 3,000 cubic feet. With cooling capacity up to 6,320 BTU/h, the system maintains stable wine storage conditions while keeping the mechanical equipment outside the wine room.
Unlike conventional air conditioners, the D050 is engineered specifically for wine storage environments. It maintains the stable 55°F cellar temperature and balanced humidity levels required for proper wine aging while minimizing temperature fluctuations that can damage wine.
Because the system is fully ducted, the cooling unit is installed remotely—typically in a mechanical room, attic, or equipment space—and connected to the cellar through insulated ductwork. This allows the wine room itself to remain quiet and visually clean without visible mechanical equipment.
The D050 is part of Wine Guardian’s Sentinel Series, designed for precise climate control, durable construction, and accessible servicing by HVAC technicians.
The Wine Guardian D050 is typically recommended for:

Recommended cellar volume
650 – 3,000 cubic feet
Maximum cooling capacity
6,320 BTU/h
System type
Self-contained ducted cooling system
Typical applications
Residential and commercial wine cellars
Actual cooling requirements depend on factors such as:
insulation quality
vapor barrier installation
glass walls or doors
lighting heat load
ambient room temperature
A professional heat load calculation is recommended before selecting a cooling system.
Key Features and Benefits
Fully Ducted Installation
The D050 is a ducted wine cellar cooling system, meaning conditioned air is delivered through insulated ductwork. This allows the equipment to be installed outside the cellar, reducing noise and preserving the cellar’s design.
Stable Wine Storage Environment
Wine ages best in a stable environment. The D050 is engineered to maintain:
Temperature: typically 55°F
Humidity: approximately 55–65% relative humidity
These conditions help prevent cork drying, oxidation, and premature aging.
Wireless2Base™ Digital Controller
The system includes Wine Guardian’s Wireless2Base™ digital controller, allowing easy adjustment and monitoring of temperature and humidity. Optional remote sensors can be added for large or complex wine rooms.
Quiet Operation
Because the cooling unit is installed outside the wine cellar and connected via ductwork, noise inside the cellar is minimized.
Durable Construction
The D050 uses an aluminum chassis with UL-rated composite panels designed to resist corrosion and maintain performance in wine cellar environments.
Optional Electric Heat
An optional electric heating module helps maintain stable cellar temperatures in cold climates or unconditioned installation spaces.
Serviceable Design
Sentinel Series units are designed so technicians can access service components easily, simplifying maintenance and reducing long-term operating costs.
What’s Included
The standard Wine Guardian D050 package includes:
Wine Guardian D050 ducted cooling unit
Wireless2Base™ digital controller
Supply and return duct collars
