| Line Frequency | 60 Hz |
| Installation Style | Flush ceiling-mounted evaporator with remote outdoor condenser |
The Wine Guardian CS025 Wine Wall Cooling System is engineered for wine wall applications where traditional visible cooling equipment would disrupt the design. The ceiling-mounted evaporator installs flush into the wine wall ceiling, while the condenser is installed remotely to help reduce heat and mechanical noise near the wine display.
This system is part of Wine Guardian’s specialized wine cellar cooling systems lineup and is designed to maintain stable storage conditions for wine collections that require controlled temperature and humidity.
For larger wine wall installations or projects requiring additional cooling capacity, compare this model with the Wine Guardian CS050 Wine Wall Cooling System.

Wine walls and glass wine displays create different cooling challenges than traditional walk-in wine cellars. They often have tighter installation spaces, more visible design surfaces, and higher aesthetic expectations. The CS025 addresses those challenges with a concealed ceiling-mounted evaporator, integrated supply and return airflow, and a remote condenser layout.
The ceiling grille sits flush with the wine wall ceiling to reduce visible equipment inside the display.
The evaporator and condenser are separated, eliminating the need for ductwork in compact wine wall installations.
The remote condenser helps move heat and mechanical noise away from the wine wall environment.
Maintains wine storage conditions between 55°F and 58°F, with the ability to cool down to 45°F for serving applications.
The low-profile grille installs flush into the ceiling for a clean, concealed appearance.
The grille is powder-coated black and can be painted to better match the surrounding design.
The dual-function grille supports controlled airflow within the wine wall enclosure.
The system supports remote monitoring and control of temperature and humidity.
Supports up to three remote air sensors and an additional controller for multi-point climate awareness.
The grille can be removed without tools to simplify service access and routine maintenance.
The lightweight corrosion-resistant chassis includes coated coils for long-term performance.
Designed specifically for wine storage instead of general room air conditioning.
Do not size or install the CS025 based on room dimensions alone. Glass exposure, insulation quality, ceiling cavity space, condenser location, electrical requirements, and ambient conditions all affect performance. Oversized, under-insulated, or poorly sealed wine walls can prevent the system from maintaining stable wine storage conditions.
The CS025 is a ductless split cooling system and should be installed by qualified professionals familiar with refrigeration, electrical work, condensate handling, and wine storage environments.
For additional planning support, review the Wine Cellar Resources page.

Helps maintain 55–65% relative humidity for cork integrity.
Supports condenser operation in extreme hot or cold installation conditions.
Supports multi-point monitoring for more precise wine wall climate management.
Provides longer-term protection for qualifying system purchases.
Designed to support stable wine storage temperature and humidity control.
Accessory selection should be confirmed against the installation environment and project requirements.

Wine storage environments typically require stable temperature and humidity rather than rapid room cooling. The CS025 is designed to help maintain wine storage temperatures commonly used for long-term preservation, with humidity management options available for projects where cork integrity is a concern.

The Wine Guardian CS025 is best suited for wine wall projects where concealed cooling, quiet operation, and visual integration are top priorities. Choose this model when the wine display falls within the proper capacity range and the project can accommodate a ceiling-mounted evaporator with a remote condenser.
For projects approaching the upper end of the recommended capacity range, compare the CS025 against the Wine Guardian CS050 Wine Wall Cooling System before finalizing the system.
Wine wall cooling performance depends on sizing, glass exposure, insulation, condenser placement, and installation conditions. Confirm your project details before ordering.
