Wine Guardian DS025 Duct Split Wine Cellar Cooling Unit

Wine Guardian DS025 Ducted Split Wine Cellar Cooling System

Sentinel Series Cooling System for Small Wine Cellars

The Wine Guardian DS025 is a ducted split wine cellar cooling system designed for small residential and light-commercial wine cellars between approximately 250 and 2,000 cubic feet. The system separates the evaporator (fan-coil) and condensing unit, allowing refrigeration components to be installed outside the cellar while maintaining quiet, stable cooling inside the wine storage environment.

This split design minimizes noise and vibration in the cellar while giving installers flexibility to place the condensing unit in a mechanical room, basement, attic, or outdoor location depending on the project requirements.

The DS025 maintains the stable temperature and humidity conditions required for proper wine aging and long-term wine storage.

For larger wine cellars, Wine Guardian also offers the DS050, DS088, and DS200 ducted split systems, which provide increased cooling capacity for larger installations.

For expanded performance and larger installations, explore the DS050 Ducted Split System, DS088 Ducted Split System, or DS200 Ducted Split System — all engineered to meet the cooling needs of mid- to large-size wine storage environments with added flexibility and power.

Quick Product Facts

Why Choose the Wine Guardian DS025

Quiet Wine Cellar Operation

Because the compressor and condenser are installed outside the cellar, the DS025 keeps the wine room quiet and vibration-free, preserving the peaceful environment expected in a wine storage space.

Flexible Installation Options

The split system allows the condenser and evaporator to be installed in separate locations. Installers can place the condenser in:

• mechanical rooms
• basements
• utility spaces
• attics
• outdoor locations (depending on climate)

This flexibility makes the DS025 suitable for projects where a self-contained system cannot exhaust heat properly.

Stable Climate Control for Wine Preservation

Wine requires consistent storage conditions. The DS025 maintains cellar temperatures within the ideal wine storage range of approximately 55°F while helping maintain humidity levels that protect corks and labels when the cellar is properly constructed.

Designed for Custom Wine Cellars

Wine Guardian systems are specifically engineered for wine cellar environments and are commonly installed in:

• residential wine cellars
• restaurant wine rooms
• tasting rooms
• hospitality wine storage areas

Split System Design

Unlike self-contained wine cooling systems, the DS025 uses two separate components.

Evaporator (Fan-Coil)

Installed near the wine cellar and connected via ductwork, the evaporator distributes conditioned air evenly throughout the cellar.

Condensing Unit

Installed remotely, the condenser removes heat from the refrigeration system and exhausts it outside the cellar environment.

This configuration allows:

• quieter cellar operation
• greater installation flexibility
• improved airflow distribution

Cooling Performance

Cooling capacity varies depending on the temperature of the air surrounding the condensing unit.

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

Actual cellar capacity will depend on factors such as:

• insulation quality
• glass doors or walls
• ambient temperature
• frequency of door openings
• duct design

Optional Accessories

The DS025 can be configured with optional components depending on cellar requirements.

Integrated Humidifier

Adds humidity control to help maintain proper relative humidity levels for cork protection and wine preservation.

All Wine Temperatures Bundle

Allows operation at lower temperatures for serving conditions or specialized wine storage needs.

Extreme Climate Protection Kit

Enhances system performance when the condenser is installed in environments with unusually high or low ambient temperatures.

Remote Sensors

Additional sensors allow monitoring temperature conditions in multiple areas of the wine cellar.
