Sentinel Series Cooling for Medium Wine Cellars
The Wine Guardian DS050 is a ducted split wine cellar cooling system designed for wine cellars between 650 and 3,000 cubic feet. The system separates the evaporator (inside the cellar) and condenser (outside the cellar) so that the compressor and heat-producing components remain outside the wine room.
This design allows the DS050 to deliver quiet operation, flexible installation, and stable wine storage conditions while keeping the mechanical equipment hidden from view.
The DS050 is commonly used in:
custom residential wine cellars
restaurant wine storage rooms
tasting rooms
hospitality wine displays
medium commercial wine storage environments
For smaller cellars, the DS025 Split System offers a compact, efficient solution. For expanded capacity and high-performance cooling, explore the DS088 or DS200 ducted split systems — both ideal for larger installations.

Who This Cooling System Is For
The Wine Guardian DS050 is best suited for wine cellars that:
✔ range between 650 and 3,000 cubic feet ✔ require quiet operation near living or entertaining spaces ✔ use ducted air distribution ✔ are part of a custom cellar design project
Consider a smaller system if:
✘ the cellar is under 500 cubic feet ✘ ductwork cannot be installed ✘ a simple plug-in cooling unit is preferred
Key Features and Benefits
Split-System Design for Quiet Cooling
The DS050 separates the evaporator and condenser into two components. The condenser is installed outside the wine cellar—usually in a mechanical room, garage, or exterior location—while the evaporator distributes conditioned air into the cellar.
This configuration keeps the compressor noise outside the wine room, creating a quiet storage environment.
Flexible Ducted Installation
Air is supplied and returned through ductwork, allowing the cooling equipment to remain hidden from view while distributing cool air evenly throughout the cellar.
This design is especially useful in custom-built wine cellars or designer wine displays.
Precision Temperature Control
Wine Guardian systems maintain stable storage temperatures around 55°F, the industry-recommended temperature for aging wine.
The DS050’s digital controls maintain temperatures with ±1°F accuracy.
Wireless2Base™ Digital Controller
The included controller allows users to monitor and adjust cellar conditions from inside the wine room.
This system provides accurate monitoring of:
temperature
humidity
system operation
Durable Commercial Construction
The DS050 uses reinforced composite panels and an aluminum chassis designed to withstand the humid conditions common in wine cellars.
The multi-panel design also allows technicians easier service access if maintenance is required.
What’s Included
Each Wine Guardian DS050 system includes the primary components required for installation.
Standard package includes:
DS050 evaporator unit
DS050 condensing unit
Wireless2Base™ digital controller
supply and return duct collars
installation and user manuals
The digital controller installs inside the wine cellar to monitor storage conditions.
Optional Accessories
Several accessories are available to customize the system for different cellar environments.
All Wine Temperatures Bundle
Allows cooling temperatures as low as 45°F for specialty wine storage.
Integrated Humidifier
Maintains proper humidity levels to protect cork integrity.
Extreme Climate Protection Kit
Allows reliable system operation in hot or cold installation environments.
Remote Sensors and Controllers
Allows monitoring of temperature and humidity in multiple cellar zones.
Duct Kits and Grilles
Provide finished airflow solutions for custom wine cellar designs.

The DS050 must be installed by a qualified HVAC technician because it uses refrigeration lines to connect the evaporator and condenser units.
Professional installation ensures:
correct refrigerant charging
proper duct airflow
reliable system operation
The condenser is typically installed in a mechanical room, garage, or exterior location where heat can dissipate safely.

📚 Frequently Asked Questions (FAQs)
Yes. The DS050 is a split-system refrigeration unit that requires installation by a licensed HVAC technician. The installer connects the evaporator and condenser using refrigerant lines and configures the airflow through ducting.
The condenser is installed outside the wine cellar in a garage, mechanical room, utility space, or exterior location where heat can dissipate safely.
Yes. Because the compressor and condenser are installed outside the cellar, the DS050 operates much more quietly inside the wine room than most self-contained cooling units.
Yes. When equipped with the optional integrated humidifier, the DS050 can maintain cellar humidity between 55% and 65% relative humidity, which helps protect corks and maintain wine quality.
The DS050 is designed for wine cellars ranging from approximately 650 to 3,000 cubic feet, depending on insulation quality, cellar construction, and ambient conditions.
Most wine collections should be stored around 55°F (13°C) with humidity between 55% and 65% relative humidity. The DS050 is designed to maintain these conditions with high accuracy."]
