WhisperKOOL Extreme 5000tiR Self-Contained Cooling Unit (w/ Remote)

Self-Contained Through-the-Wall Wine Cellar Cooling Unit (Up to 800 cu.ft.)

The WhisperKOOL Extreme 3500tiR is a self-contained, through-the-wall wine cellar cooling system designed for fully insulated residential wine rooms up to approximately 800 cubic feet.

Engineered for high ambient heat environments, this unit can maintain proper cellar conditions even when condenser intake temperatures reach up to 110°F, making it suitable for warm climates, garages, and exterior wall installations.

The 3500tiR features variable-speed fan technology, a remote digital controller, and a liquid-temperature bottle probe for precise wine storage control.

Quick Decision Guide

✔ Recommended For

• Fully insulated wine cellars up to 800 cu.ft.
• Through-the-wall installations between wall studs
• Homes in hot climates
• Installations requiring remote monitoring
• Cellars with proper vapor barrier and sealed envelope

✘ Not Recommended For

• Wine rooms larger than 900 cu.ft.
• Glass-heavy or poorly insulated cellars
• Commercial wine storage applications
• Open-concept or frequently accessed spaces

If your cellar exceeds 800 cu.ft. or includes large glass panels, consider the Extreme 5000tiR or a custom heat load evaluation.

What Makes the Extreme 3500tiR Different

Designed for High Ambient Conditions

Unlike many standard self-contained units, the Extreme 3500tiR is built to operate in condenser environments up to 110°F. This makes it appropriate for installations where mechanical rooms or outdoor air temperatures run warm.

Variable-Speed Fan Technology

The variable-speed fans improve air circulation and reduce temperature stratification within the cellar. This helps maintain consistent storage conditions throughout the room.

Remote Digital Controller (50-ft. Cable)

The Remote Platinum Series controller allows temperature monitoring and adjustments without entering the cellar. The display can be installed up to 50 feet from the cooling unit.

The controller includes Advanced System Protection, which alerts users if operational parameters fall outside recommended ranges.

Liquid-Temperature Bottle Probe

Instead of relying only on ambient air readings, the included bottle probe measures the liquid temperature of the wine. This provides a more accurate reflection of actual wine storage conditions.

Through-the-Wall Simplicity

The 3500tiR is designed to fit between standard wall studs for straightforward installation. Because it is self-contained, no external refrigeration lines are required.

Installation Requirements

To achieve rated performance, the following conditions must be met:

• Fully insulated cellar (R19 walls / R30 ceiling recommended)
• Proper vapor barrier installed
• 115V, 20-amp dedicated electrical circuit
• Adequate ventilation for condenser exhaust
• 1/2" ID drain line installed (not included)
• Exterior grille recommended for outdoor installations

Failure to properly insulate and seal the cellar may result in:

• Continuous system runtime
• Inability to reach 55°F
• Increased energy consumption
• Premature compressor wear

A professional heat load calculation is strongly recommended before selecting a cooling unit.

Understanding the 55°F Temperature Differential

The Extreme 3500tiR is capable of maintaining a 55°F cellar temperature when the condenser intake air does not exceed 110°F, assuming the room is fully insulated and sealed.

Actual performance may vary based on:

• Glass walls
• Stone or concrete construction
• Ceiling height
• Ambient humidity
• Door frequency

Final Recommendation

The WhisperKOOL Extreme 3500tiR is best suited for homeowners building a properly insulated wine cellar up to 800 cubic feet who need a through-the-wall system capable of operating in warm environments.

If your cellar exceeds 800 cu.ft., contains substantial glass, or lacks a proper vapor barrier, upgrading to a higher-capacity unit or conducting a heat load evaluation is recommended.
