CellarCool CX4400 Wine Cellar Cooling Unit

Is the CellarCool CX4400 Right for Your Wine Cellar?

The CellarCool CX4400 is a self-contained, through-the-wall wine cellar cooling system designed for fully insulated and sealed wine rooms up to 1,000 cubic feet under ideal construction conditions.

It is engineered to maintain a 55°F cellar temperature when:

• The cellar is properly insulated
• A continuous vapor barrier is installed
• The condenser intake air does not exceed 85°F
• A dedicated 115V / 20 amp circuit is provided
• Rear exhaust air can dissipate freely

If any of these conditions are not met, cooling performance will decrease.

Reminder: The CellarCool CX Series Wine Cooling Unit CX4400 requires the area it is releasing or exhausting its hot air doesn't exceed 85°F for your wine cellar to be at 55°F.

Available in CX2200 for 265 cu.ft wine cellar, CX3300 for 650 cu.ft wine cellar, CX4400 for 1000 cu.ft wine cellar, CX8800 for 2000 cu.ft wine cellar

Quick Fit Summary

Cooling Performance

Rated Capacity

• Up to 1,000 cubic feet
• Assumes fully insulated and sealed enclosure with proper vapor barrier

Cooling Output

• BTUh (with 85°F condenser intake air): 2,962 BTUh
• Horsepower: 1.16 HP
• Airflow: 216 CFM

Temperature Delta

The CX4400 can maintain a 55°F cellar temperature when condenser intake air remains at or below 85°F.

If intake air exceeds 85°F:

• Cooling efficiency declines
• Compressor strain increases
• Temperature stability may fluctuate

This unit is not designed for high-ambient mechanical rooms or enclosed exhaust spaces.

Noise Level

This sound output is typical for self-contained through-the-wall systems.

For installations in noise-sensitive areas (living spaces, glass display walls), a split system with a remote condenser may be more appropriate.

Electrical Requirements

• Voltage Rating: 115V
• Dedicated Circuit: 20 amp required
• Running Amps: 9 amps

Failure to provide a dedicated 20 amp circuit may result in:

• Breaker tripping
• Electrical overheating
• Compressor damage
• Warranty issues

Always verify panel capacity before installation.

Installation Requirements

Installation Type

• Through-the-wall

• Supports partial ducting configurations

Condenser Ventilation

Rear exhaust must:

• Discharge into a ventilated space
• Not recycle hot air
• Not be enclosed without ventilation

Improper exhaust ventilation is a common cause of overheating and premature failure.

Drainage

• 3/8” rear condensate line
• Must be routed properly to avoid backflow

Construction Requirements

To achieve rated performance, the cellar must include:

• Minimum R-19 wall insulation (or equivalent)
• Insulated ceiling
• Continuous vapor barrier on warm side
• Airtight, sealed door
• No shared HVAC air exchange

This unit is not intended for open basements or unfinished rooms.

Physical Dimensions & Weight

Confirm wall framing dimensions before cutting.

Refrigerant & Controls

• Refrigerant: R-134a
• Thermostat: Advanced digital display

The digital controller provides stable temperature regulation for wine storage environments.

• Owner's Manuals

Warranty Coverage

• 2-Year Parts & Labor Warranty
• 5-Year Compressor Warranty

Warranty applies when installation meets manufacturer guidelines.

Professional installation is recommended.

Who Should Choose the CX4400?

Choose This Unit If:

• Your cellar is under 1,000 cu. ft.
• Construction includes proper insulation and vapor barrier
• Intake air remains below 85°F
• You have a 20 amp dedicated circuit available
• Rear ventilation space is adequate

Do Not Choose This Unit If:

• The room exceeds rated volume
• The space lacks a vapor barrier
• Exhaust air cannot dissipate freely
• Ambient intake temperatures exceed 85°F
• You require ultra-quiet operation
• The cellar includes large uninsulated glass surfaces

In those cases, a higher-capacity or split system may be required.

Final Decision Summary

The CellarCool CX4400 is a self-contained cooling solution for wine cellars up to 1,000 cubic feet when construction and installation requirements are met.

Before purchasing, confirm:

• Total cubic footage
• Insulation quality
• Vapor barrier integrity
• Dedicated 20 amp circuit availability
• Rear exhaust ventilation space
• Intake air remains under 85°F

If these conditions cannot be met, this unit may not perform as rated.
