Product Overview
The CellarCool CX3300 Wine Cellar Cooling Unit is built for homeowners and wine collectors who need dependable cooling for a medium-sized wine cellar. When installed in a properly constructed wine cellar, the CX3300 can support approximately 650 cubic feet of conditioned wine storage space.
This through-the-wall wine cellar cooling system combines efficient cooling performance with user-friendly operation. Its advanced digital controller, dynamic airflow design, heavy-duty coils, and built-in system protection features help create stable storage conditions for aging and preserving wine collections.
The CX3300 is designed to install between standard wall studs without requiring support shelves. This makes it a practical option for many residential wine cellar projects where simple installation, compact equipment placement, and reliable cellar cooling are priorities.
Important: Heat load calculations should always be performed before selecting a wine cellar cooling unit. Cellar size, insulation quality, vapor barrier installation, glass exposure, door sealing, ambient temperature, and usage patterns can all affect cooling performance.
Key Features
Through-the-Wall Installation
The CX3300 installs directly through the wine cellar wall, making it a practical option for residential projects that do not require a remote condenser or full split-system configuration.
Dynamic Airflow Design
Engineered airflow helps distribute conditioned air throughout the cellar to support consistent wine storage temperatures and reduce hot or cold spots.
Advanced Digital Controller
The user-friendly digital display allows cellar temperature monitoring and adjustment for maintaining proper wine storage conditions.
Heavy-Duty Coils
Durable cooling components support reliable long-term performance when the unit is installed in a properly constructed wine cellar environment.
System Safety Management
Built-in SSM and anti-frost protection help protect system performance and reduce operational risks during normal use.
Multiple Mounting Options
Flexible mounting design allows the unit to adapt to different cellar layouts and wall configurations.
Vibration-Free Operation
Designed to minimize vibration transfer, helping protect wine during long-term storage and aging.
Made in the USA
Manufactured in the United States using quality components and engineering standards trusted by wine collectors.
Installation Requirements
Proper wine cellar construction is essential to achieving the rated performance of the CellarCool CX3300. This unit is intended for through-the-wall installation in a fully insulated, sealed, and vapor-protected wine room.
Wine Cellar Requirements
- Fully insulated cellar enclosure
- Proper vapor barrier installation
- Sealed doors and wall penetrations
- Appropriate cellar construction for wine storage
- Proper condensate drainage
Electrical and Exhaust Requirements
- 115V power supply
- 20 amp dedicated circuit required
- 3/8" condensate drain line, rear location only
- Condenser intake/exhaust area should not exceed 85°F
- Through-the-wall or partially ducted installation only
No licensed HVACR technician is typically required for standard through-the-wall installation, but electrical work and cellar preparation should follow local code requirements.
Performance Considerations
The CX3300 is rated for approximately 650 cubic feet only when the wine cellar is properly built for wine storage. Poor insulation, missing vapor barrier, warm adjacent spaces, glass doors, high traffic, or air leakage can reduce real-world cooling performance.
To maintain a 55°F cellar temperature, the area where the unit releases or exhausts hot air should not exceed 85°F. If the exhaust space is warmer than 85°F, a different cooling solution may be required.
Actual performance depends on insulation quality, cellar location, door construction, glass exposure, ceiling height, ambient temperature, and total heat load.

Wine Coolers Empire Expert Recommendation
We recommend the CellarCool CX3300 for residential wine collectors building or upgrading a properly insulated wine cellar up to approximately 650 cubic feet. It is especially useful when a straightforward through-the-wall cooling solution is preferred over a split system or remote condenser setup.
For collectors who anticipate future cellar expansion, have higher ambient temperatures, or are unsure about insulation and vapor barrier performance, a larger CX Series model or an alternative wine cellar cooling system may be more appropriate.
