WhisperKOOL Extreme 8000tiR Fully Ducted Wine Cellar Cooling Unit

WhisperKOOL Extreme 8000tiR Fully Ducted Wine Cellar Cooling Unit

The WhisperKOOL Extreme 8000tiR Ducted Cooling Unit is a powerful, self-contained system engineered to provide reliable cooling for wine cellars up to approximately 2,000 cubic feet. Designed for both residential and commercial applications, this unit ensures consistent temperature and humidity levels, helping preserve wine collections under optimal conditions.

Built with advanced cooling technology, the Extreme 8000tiR features variable-speed fans and a smart thermostat system that adapts to the cellar’s cooling demands. Its fully ducted capability allows the unit to be installed up to 25 feet away from the cellar, offering flexibility while maintaining a quiet and visually unobtrusive environment.

This system is designed to perform in extreme environments, capable of maintaining stable cellar temperatures between 55°F and 65°F with proper insulation and sealing. Its liquid-temperature bottle probe provides accurate readings by measuring the actual wine temperature rather than ambient air.

With a KDT Plus remote controller and multiple installation options, the Extreme 8000tiR offers convenience, durability, and efficient performance. It is an ideal solution for collectors seeking a high-capacity cooling unit that combines flexibility, precision, and quiet operation.

Who This System Is For

The Extreme tiR is appropriate if:

• Your cellar is fully insulated (minimum R-19 walls, R-30 ceiling)
• A continuous vapor barrier is installed on the warm side of insulation
• You need the cooling equipment installed remotely (attic, mechanical room, adjacent space)
• Maximum duct run does not exceed 25 equivalent duct feet
• Condenser intake air does not exceed 110°F
• A quiet in-cellar environment is required

Who Should Not Use This System

The Extreme tiR may not be appropriate if:

• The cellar exceeds the rated cubic footage
• Insulation or vapor barrier is incomplete or improperly installed
• Significant glass exposure increases heat load beyond capacity
• Duct runs exceed 25 equivalent feet
• Ambient intake air regularly exceeds 110°F
• The installation space cannot provide adequate airflow

Improper installation is the most common cause of cooling system failure.

What Makes the Extreme tiR Fully Ducted?

Unlike through-the-wall systems, the Extreme tiR allows both evaporator and condenser sides to be ducted, enabling:

• Installation up to 25 equivalent duct feet away
• Reduced mechanical noise inside the cellar
• Flexible exhaust routing
• Cleaner cellar aesthetics

Unit plenums ship unpainted.

Cooling Capacity & Model Sizing

The following capacities assume:

• Proper insulation
• Continuous vapor barrier
• Fully sealed door
• Maximum 110°F condenser intake air

*Capacities are approximate and assume proper insulation and vapor sealing.

If your cellar size is near the upper limit, or includes glass walls, warm climate exposure, or concrete construction, sizing up may be required.

Installation Requirements

Insulation & Vapor Barrier

For rated performance:

• Minimum R-19 wall insulation
• Minimum R-30 ceiling insulation
• Continuous vapor barrier (minimum 6-mil polyethylene)
• All penetrations sealed
• Insulated, gasketed door

Without proper insulation and vapor barrier, condensation and insufficient cooling will occur.

Ducting Requirements

• Maximum 25 equivalent duct feet
• Equivalent length includes elbows and transitions
• 10" return duct
• 8" supply duct (evaporator and condenser)
• Proper airflow must be maintained to prevent static pressure restriction

Exceeding duct limits can reduce cooling capacity and cause short cycling.

Electrical Requirements

• 115V (20 amp dedicated circuit required)
• 230V option (subject to availability)
• Running amps: 9–10 (model dependent)

Control & Monitoring System

The Extreme tiR includes the Remote Platinum Series Controller featuring:

• Advanced System Protection Technology
• Multiple internal monitoring probes
• Quick-Chill mode
• Anti-Frost function
• Liquid-temperature measuring bottle probe
• 50 ft. remote digital display cable

The bottle probe measures actual liquid temperature, reducing rapid cycling caused by ambient air fluctuation.
