Wine Guardian DP50 Pro Ducted Wine Cellar Cooling Unit

Professional Climate Control for Medium-Sized Wine Cellars

The Wine Guardian DP50 Pro is a self-contained ducted wine cellar cooling system designed to maintain precise temperature and humidity conditions in wine cellars between 650 and 3,000 cubic feet. Delivering up to 6,920 BTU of cooling capacity, the DP50 Pro provides quiet, evenly distributed airflow while allowing the mechanical equipment to be installed outside the wine cellar space.

As part of the Wine Guardian Sentinel Series, the DP50 Pro is engineered for reliability, serviceability, and integration with modern home automation systems. Its fully ducted design allows conditioned air to be delivered discreetly through insulated ductwork, keeping the cooling equipment hidden while maintaining ideal wine storage conditions.

The system is commonly used in residential wine rooms, restaurant wine storage areas, and hospitality cellars where consistent climate control and quiet operation are essential for protecting valuable wine collections.

For smaller projects requiring the same level of precision, the DP25 Pro offers similar features at a reduced capacity. For larger cellars, consider the DP88 Pro or DP200 Pro, both engineered to deliver maximum control and airflow for expansive spaces.

Quick System Overview

Why Choose a Ducted Wine Cellar Cooling System

Unlike through-the-wall units that install directly in the cellar wall, ducted cooling systems deliver conditioned air through insulated ductwork from a remote location. This approach allows the cooling equipment to be installed in a mechanical room, basement, attic, or nearby utility space, keeping the wine cellar quiet and visually clean.

Advantages of ducted wine cellar cooling systems include:

• Quiet cellar environment
• Hidden installation
• Even air distribution
• Flexible installation locations
• Improved aesthetic for custom wine cellars

These benefits make ducted systems especially popular for luxury residential wine rooms and hospitality installations.

Ideal Applications for the DP50 Pro

The Wine Guardian DP50 Pro is designed for installations that require discreet climate control and reliable cooling performance.

Best suited for

• Residential wine cellars
• Restaurant wine rooms
• Hospitality wine storage
• Custom luxury wine cellars
• Homes with remote mechanical spaces

Recommended cellar size

650 – 3,000 cubic feet

If your cellar is smaller than this range, the DP25 Pro may be a better option. Larger wine rooms may require the DP88 Pro or DP200 Pro.

Key Features and Benefits

Self-Contained Ducted Cooling Design

The DP50 Pro integrates the compressor, condenser, and evaporator within a single system, simplifying installation compared with split cooling systems. Conditioned air is delivered through ductwork to maintain consistent cellar conditions.

Quiet Operation

Because the system is installed outside the cellar space, the wine room remains quiet and free from mechanical noise or vibration, making it ideal for residential and hospitality environments.

Precision Temperature Control

Wine Guardian systems are designed to maintain optimal wine storage conditions:

• Temperature range: 52°F – 70°F
• Stable humidity conditions to protect corks
• Consistent airflow to prevent temperature stratification

Maintaining stable cellar conditions allows wine to age properly and maintain its quality over time.

Durable Construction

The DP50 Pro is built using high-quality materials designed for long-term reliability:

• Aluminum structural chassis
• UL-rated composite panels
• Powder-coated metal exterior
• High-efficiency insulation to reduce condensation and energy loss

Smart Control Integration

The system uses 24-volt control architecture, allowing compatibility with:

• home automation systems
• building management systems (BMS)
• remote monitoring solutions

This allows property owners and installers to easily monitor cellar temperature and system performance.

Service-Friendly Design

Wine Guardian systems are designed with maintenance access in mind. The DP50 Pro includes:

• service ports
• removable access panels
• diagnostic ports

These features simplify servicing and long-term system maintenance.

Optional Accessories and Upgrades

The DP50 Pro can be configured with several optional accessories depending on the installation requirements.

Available options include:

• Electric heat kit
• Integrated humidifier
• Freestanding humidifier
• Water-cooled condenser configuration
• Wireless2Base™ remote monitoring
• Duct kits and adapters
• Extended warranty options

These accessories allow installers to customize the system for different cellar environments and climate conditions.

What’s Included

Each Wine Guardian DP50 Pro system includes:

• Wine Guardian DP50 Pro cooling unit
• Interchangeable duct collar set
• Installation and operation manual
• Factory-installed electronic controls

Additional installation components such as ductwork, grilles, thermostats, and humidifiers are selected based on the cellar design.

Installation Considerations

Proper cellar construction is essential for cooling performance.

Recommended cellar construction typically includes:

• Adequate insulation (commonly R-19 walls and R-30 ceilings)
• Airtight doors and sealed penetrations
• Properly sized ductwork

Professional installation by a qualified HVAC contractor or wine cellar specialist is strongly recommended.
