WhisperKOOL Ceiling Mount Twin 9000 Ductless Split Wine Cellar Cooling System The WhisperKOOL Ceiling Mount Twin 9000 is a ductless split wine cellar cooling system designed for wine cellars up to approximately 3,000 cubic feet. The system uses dual evaporator units installed flush within the cellar ceiling and a remote condenser located outside the cellar to maintain stable wine storage temperatures around 55°F, the ideal temperature for long-term wine preservation. Because the cooling equipment is mounted in the ceiling and the condenser can be installed remotely, the system keeps the wine cellar quiet, efficient, and visually clean while maintaining precise temperature control. The Ceiling Mount Twin 9000 is particularly well suited for custom residential wine cellars, luxury wine rooms, and commercial wine displays where both cooling performance and cellar aesthetics are important.

Who This Cooling System Is Best For The WhisperKOOL Ceiling Mount Twin 9000 is ideal for: Wine cellars up to 3,000 cubic feet Custom wine rooms where cooling equipment must remain hidden Luxury residential wine cellars Commercial wine storage or wine display rooms Installations where quiet operation is important Projects where through-wall cooling units are not suitable Key Features Dual Evaporator Design for Larger Cellars The Ceiling Mount Twin 9000 uses two evaporator units, increasing cooling capacity and ensuring consistent temperature control in larger wine storage environments. This dual-unit configuration improves air circulation and allows the system to maintain stable cellar conditions more efficiently. Flush Ceiling Installation Each evaporator installs flush between ceiling joists, allowing the cooling system to remain virtually invisible inside the wine cellar. This design preserves the visual appeal of the wine collection and custom cellar design. KDT Digital Touch Display The KDT digital touch controller allows easy monitoring and adjustment of cellar conditions. Features include: Remote display installation up to 50 feet away System monitoring and alert notifications Simple digital temperature control Liquid Temperature Bottle Probe Unlike systems that measure only air temperature, the bottle probe measures liquid temperature, which provides a more accurate representation of the wine's actual storage temperature. This helps prevent temperature fluctuations that can affect wine quality. Air Filtration System An integrated air filter protects the cooling unit from dust and debris, particularly during installation or rack construction, helping extend the system's operational life. Installer-Friendly Design The redesigned unit improves installation access by placing electrical connections, bottle probe wiring, and refrigeration line connections at the bottom of the unit. The system also includes flare fittings, eliminating the need for brazing and simplifying installation. How the WhisperKOOL Ceiling Mount Twin 9000 Works The system operates using a split refrigeration system consisting of evaporators inside the wine cellar and a condenser located outside the cellar. Evaporator Units Two evaporators are installed flush in the ceiling of the wine cellar. These units draw warm air from the cellar, cool it through the refrigeration system, and circulate cooled air evenly throughout the room. Condenser Unit The condenser is installed outside the wine cellar, typically in a mechanical room, garage, or exterior location. The condenser removes heat from the refrigeration system and can be positioned up to 100 line feet away from the evaporators. This split configuration keeps the wine cellar quiet and temperature-stable while minimizing visible equipment. Installation Requirements Important:The WhisperKOOL Ceiling Mount systems must be installed by a qualified HVAC-R technician. Failure to have the system installed by a qualified professional will void the manufacturer's warranty. Professional installation ensures: Proper refrigeration line installation Correct electrical connections Accurate heat load calculations Reliable system performance Because every wine cellar is unique, professional installers should evaluate insulation, vapor barriers, glass walls, and other environmental factors before selecting a cooling system.

Important Cellar Capacity Note Cellar capacity estimates assume the wine cellar is fully insulated and sealed with a proper vapor barrier. Cellars with glass walls, stone construction, or insufficient insulation may require a larger cooling system. Professional heat load calculations should always be performed before selecting a cooling unit.
