CellarCool CX3300 Wine Cellar Cooling Unit

Through-the-Wall Cooling for Properly Constructed Wine Cellars Up to 650 Cu. Ft.

The CellarCool CX3300 is a self-contained, through-the-wall wine cellar cooling system designed for fully insulated, vapor-barrier-sealed wine cellars up to 650 cubic feet.

It delivers 2049 BTUh of cooling capacity (rated with 85°F condenser intake air) and is engineered to maintain stable 55°F storage conditions when installed correctly.

This unit will not compensate for structural deficiencies, insulation gaps, or excessive ambient heat.

Reminder: The CellarCool CX Series Wine Cooling Unit CX3300 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 Suitability Check

This unit is appropriate if:

• Your cellar is 650 cu. ft. or smaller
• Walls and ceiling are fully insulated
• A continuous vapor barrier is installed
• Condenser intake air does not exceed 85°F
• You have a 115V dedicated 20 amp circuit
• Rear exhaust air can be properly ventilated

If any of the above are not true, performance may be reduced.

Who This Unit Is Designed For

The CX3300 is best suited for:

• Medium-sized residential wine rooms
• Retrofits where through-the-wall installation is preferred
• Installations with accessible rear exhaust ventilation
• Environments with stable ambient conditions

Who Should Not Use This Unit

This model is not appropriate when:

• The cellar exceeds 650 cu. ft.
• The room has extensive glass exposure
• Ceiling height significantly increases cubic volume
• Insulation is incomplete or below recommended R-values
• The condenser exhaust area traps heat
• Ultra-quiet operation is required in living spaces

In these cases, a larger unit or split system may be more appropriate.

What “Up to 650 Cu. Ft.” Actually Assumes

The rated capacity assumes:

• Minimum R-13 wall insulation
• Minimum R-19 ceiling insulation
• Continuous vapor barrier
• Sealed door with weather stripping
• Limited glass exposure
• Ambient condenser intake ≤ 85°F

If your cellar includes:

• Floor-to-ceiling glass
• High ceilings
• Excessive lighting heat load
• Frequent door opening
• Poor ventilation

Effective cooling capacity will decrease.

Temperature Performance

The CX3300 can maintain a 55°F cellar temperature when condenser intake air is 85°F or below.

If condenser intake air exceeds 85°F:

• Cooling efficiency decreases
• Compressor strain increases
• Temperature stability may decline

Adequate rear ventilation is critical.

Installation Requirements

The CX3300 is designed for through-the-wall installation with rear exhaust.

Required:

• Framed wall opening
• Proper rear exhaust ventilation
• Dedicated 115V 20A circuit
• 3/8” condensate drainage
• Mechanical space that does not recirculate hot air

Improper installation commonly causes:

• Short cycling
• Excess noise
• Overheating
• Premature compressor failure

Professional installation is strongly recommended.

Noise Expectations

Rated at:

• 63 dBA (evaporator side)
• 64 dBA (condenser side)

This is similar to normal conversation. It is audible and not silent.

For wine rooms adjacent to living spaces, acoustic planning should be considered.

Humidity Support

The CX3300 helps maintain stable humidity only when the cellar is properly sealed.

It does not actively humidify and will not correct:

• Air leakage
• Missing vapor barriers
• Structural humidity loss

What Reduces Performance

The unit will struggle if:

• Insulation is below recommended R-values
• Vapor barrier is incomplete
• Condenser intake exceeds 85°F
• Exhaust air is trapped in enclosed space
• Cellar size exceeds rating

Wine cooling systems preserve controlled environments — they do not fix construction defects.

Maintenance Requirements

To maintain performance:

• Clean intake filters regularly
• Inspect rear ventilation area
• Ensure condensate drain remains clear
• Schedule annual inspection

Neglected maintenance increases compressor wear and reduces lifespan.

Warranty Coverage

• 2 Years Parts & Labor
• 5 Years Compressor Coverage

Warranty requires:

• Proper installation
• Operation within ambient limits
• Dedicated circuit compliance

Final Recommendation

The CellarCool CX3300 is a reliable through-the-wall cooling solution for properly constructed wine cellars up to 650 cubic feet.

Its performance depends on:

• Correct sizing
• Adequate insulation
• Vapor barrier integrity
• Proper ventilation
• Electrical compliance

If you are uncertain whether your cellar meets these conditions, a load calculation should be completed before purchase.
