WhisperKOOL Extreme 5000tiR Fully-Ducted Wine Cellar Cooling System

Is the WhisperKOOL Extreme 5000tiR Right for Your Wine Cellar?

The WhisperKOOL Extreme 5000tiR is a fully-ducted, self-contained wine cellar cooling system designed for properly insulated residential or light commercial wine cellars up to 1,250 cubic feet.

It is ideal when you want:

• Cooling equipment hidden outside the cellar
• Quiet operation inside the room
• Ducted installation up to 25 feet away
• Reliable performance in warmer climates (up to 110°F condenser intake air)

This unit maintains a 55°F cellar temperature when installed within manufacturer specifications.

Other sizes: WhisperKOOL Extreme 3500 tiR Ducted for 800 cu.ft. wine cellar & WhisperKOOL Extreme 8000 tiR Ducted for 2000 cu.ft wine cellar.

Use This Model If:

• Your cellar is 800–1,250 cu. ft.
• Walls are insulated to minimum R19 (R30 ceiling recommended)
• A proper vapor barrier is installed
• Duct runs are 25 feet or less
• You have a dedicated 115V, 20-amp circuit
• Ambient condenser intake air does not exceed 110°F

Choose a Larger Model (8000tiR) If:

• Cellar exceeds 1,250 cu. ft.
• Multiple glass walls increase heat load
• You are in a hot climate with frequent 95°F+ outdoor temperatures
• Door opening frequency is high (commercial application)
• Heat load calculation exceeds 3,794 BTU

Cellar size alone does not determine the correct unit. Heat load must consider insulation, glass, lighting, and ambient conditions.

Key Performance Highlights

Fully-Ducted Installation

Designed for hidden installation outside the cellar. Ducting allows flexible placement up to 25 feet away from the room.

Extreme Temperature Capability

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

Quiet Interior Operation

Cooling components are removed from the cellar, reducing noise and vibration inside the wine storage space.

Advanced Digital Controller

Includes:

• 50-ft. display cable
• Bottle probe (liquid temperature monitoring)
• Optional 24V thermostat compatibility

Bottle Probe Technology

Measures the temperature of the wine liquid, not just ambient air, for more accurate cellar stability.

Installation Requirements

Proper installation is critical for performance and warranty protection.

Minimum Requirements:

• Fully insulated room
• Continuous vapor barrier (6-mil minimum recommended)
• Dedicated 20-amp circuit (115V standard; 230V subject to availability)
• Duct size: 10" return / 8" supply
• Maximum 25 duct feet
• Drain line required (1/2" ID tubing; not included)

Exceeding duct length or installing in uninsulated spaces may reduce performance and void warranty.

Professional installation is strongly recommended.

Technical Specifications

*Cellar must be fully insulated and sealed.
