Wine Guardian D050WC Ducted Water Cooled Wine Cooling Unit

Wine Guardian D050WC Water-Cooled Ducted Wine Cellar Cooling System – Sentinel Series

The Wine Guardian D050WC is a water-cooled ducted wine cellar cooling system designed for wine rooms up to approximately 3,000 cubic feet. Instead of exhausting hot air like traditional air-cooled systems, the D050WC removes heat through a closed-loop water source, making it ideal for installations where condenser ventilation is not possible.

This design allows the unit to be installed in condos, basements, urban homes, restaurants, and commercial buildings where venting condenser air is difficult or restricted.

Because the system is fully ducted, the cooling unit can be installed remotely from the wine cellar, reducing noise and preserving the visual design of the wine room.

For smaller wine rooms, the D025WC Water-Cooled Cooling System provides a compact, high-performance option. For greater coverage and larger cellar environments, consider the D088WC or the robust D200WC Water-Cooled System.

Quick Overview

When to Use the D050WC Cooling System

Water-cooled wine cooling systems are typically used when air-cooled systems cannot vent condenser heat.

The D050WC is commonly installed in:

• High-rise condominiums
• Urban residential homes
• Basement wine cellars
• Commercial wine displays
• Buildings with chilled water loops
• Geothermal or lake-water cooling systems

Because heat is rejected through water instead of air ventilation, the system can operate in enclosed mechanical spaces without overheating.

When a Water-Cooled System May Not Be Ideal

The D050WC may not be the best choice if:

• A closed-loop water source is unavailable
• Plumbing installation is difficult or costly
• Water usage costs are high
• An air-cooled system can be easily vented

In those cases, a ducted air-cooled wine cellar cooling system may be simpler to install.

How the D050WC Water-Cooled Cooling System Works

The D050WC uses a water-cooled condenser to remove heat from the refrigeration system.

Instead of exhausting hot air through ductwork, the condenser transfers heat into a circulating water loop.

Common water sources include:

• Geothermal cooling systems
• Cooling towers
• Building chilled-water loops
• Lake-water cooling systems

This method allows the cooling system to operate quietly and efficiently without external ventilation.

Key Features and Benefits

Water-Cooled Heat Rejection

Transfers heat to a water loop instead of exhausting hot air, enabling installation in enclosed buildings or high-rise environments.

Fully Ducted Installation

Allows the cooling unit to be located outside the cellar to reduce noise and preserve cellar aesthetics.

Wireless2Base™ Digital Controller

Provides digital temperature control and supports up to three remote sensors for monitoring cellar conditions.

Precision Climate Control

Maintains stable storage conditions with ±1°F temperature accuracy.

Durable Cabinet Construction

Aluminum chassis and UL-rated composite panels reduce vibration and resist corrosion.

Flexible Installation Options

Multiple ducting configurations support custom cellar layouts and mechanical room installations.

Field-Serviceable Design

The unit can be serviced on site without returning it to the factory.

Performance Specifications

Cooling capacity varies depending on condenser inlet temperature.

Note: Cooling capacity ratings assume cellar conditions of 57°F and 55% relative humidity at rated airflow.

Installation Considerations

Proper installation is critical for optimal performance.

Key requirements include:

• A closed-loop water supply
• Proper cellar insulation and vapor barrier
• Correct duct sizing and airflow design
• Installation by a qualified HVAC or wine cellar specialist

Before selecting a cooling unit, a heat load calculation should always be performed to determine the correct system capacity for the wine cellar.
