WhisperKOOL Extreme 3500tiR Fully Ducted Wine Cellar Cooling Unit

WhisperKOOL Extreme 3500tiR Fully Ducted Wine Cellar Cooling Unit

The WhisperKOOL Extreme 3500tiR Ducted Cooling Unit is a high-performance, fully ducted system designed for wine collectors who require powerful and discreet cooling. Built to operate efficiently in extreme conditions, this system delivers reliable temperature control while keeping all equipment hidden from view, making it ideal for maintaining both cellar performance and aesthetics.

Engineered with variable-speed fan technology, the unit ensures optimal airflow and stable cooling conditions for wine preservation. Its fully ducted design allows installation up to 25 ducted feet away from the cellar, offering flexibility in placement while maintaining a quiet environment inside the wine room.

The system includes a KDT Plus remote controller and thermostat, enabling users to monitor and adjust cellar conditions from up to 50 feet away. With advanced system protection and precision temperature control, it provides peace of mind for long-term wine storage.

Designed for durability and efficiency, the Extreme 3500tiR maintains ideal cellar conditions even in high ambient temperatures. Its robust construction and quiet operation make it a dependable solution for residential and commercial wine cellars requiring consistent performance.

Who This System Is Designed For

The 3500tiR is appropriate for:

✔ Properly insulated wine cellars up to 800 cu. ft.
✔ Projects requiring quiet cellar operation
✔ Installations where the unit must be hidden
✔ Mechanical room, garage, or attic placement (within temperature limits)
✔ Warm-climate installations where intake air may approach 110°F

Capacity assumes correct insulation, vapor barrier installation, and completed heat load calculation.

When This System Is Not Recommended

This unit may not be appropriate if:

✘ The cellar exceeds 800 cubic feet
✘ The space contains significant glass or high heat-load materials without engineering review
✘ No vapor barrier is installed
✘ Duct runs exceed 25 equivalent feet
✘ Condenser intake air regularly exceeds 110°F
✘ A dedicated 115V, 20-amp circuit cannot be provided

Improper sizing or installation may result in short cycling, inability to maintain temperature, or premature compressor failure.

Why Choose a Fully Ducted System?

Fully ducted systems allow both the evaporator and condenser to be remotely located. This provides:

• Reduced noise inside the wine cellar
• Greater installation flexibility
• Improved aesthetic control within the cellar
• Controlled exhaust air routing

The 3500tiR can be installed up to 25 equivalent ducted feet away from the cellar when properly engineered.

Key Performance Features

Remote Platinum Series Controller

Includes:

• Advanced digital display (50-ft. cable)
• Liquid-temperature bottle probe (50-ft. cable)
• Quick-chill mode
• Anti-frost protection
• Advanced System Protection Technology with monitoring probes

The bottle probe measures actual liquid temperature rather than ambient air, improving stability and reducing compressor cycling.

Designed for High Ambient Conditions

The system can maintain 55°F cellar temperature with condenser intake air up to 110°F.
Exceeding this limit may reduce performance and shorten compressor lifespan.

Thermostat Options

Available with:

• Standard WhisperKOOL controller
• Optional 24V thermostat configuration

Note: If selecting 24V configuration, a compatible third-party thermostat must be supplied and configured by the installer.

Technical Specifications

*Capacity assumes fully insulated, vapor-sealed enclosure.

Installation Requirements

Proper installation is critical to performance and warranty protection.

Before selecting this model, confirm:

1. A heat load calculation has been performed.
2. The cellar has continuous insulation and vapor barrier.
3. Duct runs do not exceed 25 equivalent feet.
4. Condenser intake air remains within specified limits.
5. A dedicated 115V, 20-amp circuit is available.
6. Drain routing is properly planned.

Failure to meet these conditions may prevent the system from maintaining temperature.

Capacity & Sizing Guidance

The 800 cu. ft. rating is based on:

• Fully insulated enclosure
• Proper vapor barrier
• Minimal glass exposure
• Controlled surrounding environment

Cellars with:

• Glass walls or doors
• Stone or concrete construction
• High ceilings
• Warm mechanical rooms

may require a larger capacity model such as the 5000tiR.

Undersizing is the most common cause of cooling system failure.

Warranty

The WhisperKOOL Extreme 3500tiR includes:

• Two-Year Limited Warranty (Parts and Labor)
• Five-Year Limited Warranty (Compressor)

Warranty coverage assumes proper installation and operating conditions.

Fully Ducted Self-Contained

The WhisperKOOL Extreme 3500tiR is a fully ducted cooling system designed for properly insulated wine cellars up to 800 cubic feet requiring quiet operation and remote installation flexibility.

Correct sizing, duct design, and vapor sealing are essential for long-term performance.
