WhisperKOOL Extreme 5000ti Self-Contained Cooling Unit

Is the WhisperKOOL Extreme ti the Right Cooling System for Your Wine Cellar?

The WhisperKOOL Extreme ti Series is a self-contained, through-the-wall cooling system designed for properly insulated residential and light commercial wine cellars.

This system is appropriate if:

• Your cellar is fully insulated and sealed with a continuous vapor barrier
• You prefer a self-contained unit (no remote condenser)
• The condenser intake temperature will not exceed 110°F
• You can provide a dedicated electrical circuit
• Your cellar size falls within the rated capacity

This system may not be appropriate if:

• The cellar contains significant glass walls or doors
• Insulation is below recommended levels
• Exhaust air temperature exceeds 110°F
• Ultra-quiet remote condenser placement is required
• The cellar exceeds 2,000 cubic feet

A professional heat load calculation is strongly recommended before final model selection.

Available Models & Rated Capacity

*Capacity assumes a fully insulated cellar constructed with proper vapor barrier and minimal glass exposure.

Cellar size alone does not determine performance. Construction materials and ambient conditions significantly affect cooling demand.

How the Extreme ti System Works

The Extreme ti is a self-contained cooling unit. Both the evaporator (cellar side) and condenser (exhaust side) are housed in a single chassis that installs through the wall.

• Cool air is delivered into the cellar from the front.
• Warm air is exhausted from the rear.
• A bottle probe measures liquid temperature rather than air temperature.

Because the condenser remains attached to the unit, no remote installation or refrigeration line set is required.

However, proper cellar construction is critical. Without correct insulation and vapor barrier, no cooling unit will perform to rated capacity.

Key Features Explained

Through-the-Wall Installation

Designed to fit between standard wall studs. Suitable for interior or exterior wall mounting. Exterior installations require proper weather protection and grille coverage.

Variable-Speed Fans

Adjustable fan speeds allow better temperature stabilization and improved air circulation throughout the cellar.

High Ambient Operation

Engineered to maintain 55°F cellar temperature with condenser intake air up to 110°F.

If intake air exceeds 110°F:

• Cooling capacity decreases
• Runtime increases
• Compressor wear may accelerate

Advanced Digital Controller

Front-mounted digital display allows temperature monitoring and adjustment from inside the cellar.

Liquid-Temperature Bottle Probe

Measures the actual liquid temperature of stored wine, reducing short cycling and improving storage consistency.

Ducting Capability

The condensing side can be ducted if airflow requirements are maintained. Improper duct design can reduce cooling efficiency and void performance expectations.

Temperature Differential

Capable of maintaining a 55°F cellar temperature when intake air does not exceed 110°F and construction standards are met.

Installation Requirements

To perform as rated, the cellar should include:

• Minimum R-19 wall insulation
• Recommended R-30 ceiling insulation
• Continuous vapor barrier (warm side of insulation)
• Airtight door assembly
• Dedicated electrical circuit
• Proper drain routing
• Adequate condenser exhaust airflow

Failure to meet these conditions may result in inability to maintain temperature and increased compressor runtime.

Performance Limits & Sizing Guidance

Cellar performance depends on more than cubic footage.

Heat load increases significantly with:

• Glass walls or doors
• Stone or concrete construction
• High ambient temperatures
• Frequent door openings
• Inadequate vapor barrier

Selecting an undersized unit may result in:

• Inability to maintain 55°F
• Excessive compressor runtime
• Increased humidity fluctuation
• Reduced equipment lifespan

Oversizing may cause:

• Short cycling
• Inconsistent humidity control

Professional heat load verification is recommended before selecting a model.
