Ductless Split Wine Cellar Cooling System for Cellars up to 3,500 Cu. Ft.
The WhisperKOOL Ceiling Mount Twin 12000 (220V High-Efficiency) is a ductless split wine cellar cooling system engineered for large residential and light commercial wine cellars up to approximately 3,500 cubic feet.*
Designed to mount flush between ceiling joists, the dual-evaporator configuration provides strong, even airflow while keeping the cooling equipment discreetly integrated into the cellar ceiling. The remote condenser relocates heat and noise outside the wine room, creating a stable, quiet environment ideal for long-term wine storage.
This model is best suited for collectors seeking high-capacity performance without visible wall-mounted equipment or ductwork.
Projects requiring dual evaporator airflow distribution
May Not Be Suitable If:
The cellar exceeds 3,500 cubic feet
The space includes large glass walls or uninsulated surfaces
Vapor barrier or insulation is incomplete
The cellar is located in extreme ambient heat without additional load calculation
*Performance ratings assume a fully insulated, sealed cellar with proper vapor barrier. A professional heat load calculation is strongly recommended prior to equipment selection.

When to Choose the Twin 12000 Instead of the Twin 9000
Choose the Twin 12000 if:
Your cellar exceeds 3,000 cubic feet
You have glass doors or partial glass walls
You live in high-heat climates (AZ, NV, TX, FL)
You want additional cooling margin to reduce compressor strain
For smaller cellars under 3,000 cu. ft., the Twin 9000 may be sufficient.
Optional 24V Thermostat Conversion Kit
The 24V conversion kit allows integration with third-party smart thermostats.
Potential capabilities include:
Wi-Fi temperature control
Energy monitoring
Alarm notifications
Remote condition viewing
Note: WhisperKOOL does not supply smart thermostats. Selecting the 24V option replaces the standard controller and bottle probe. Manufacturer support does not extend to third-party thermostat issues.
