WhisperKOOL Extreme 3500tiR Fully Ducted Wine Cellar Cooling System
What It Is (Quick Overview)
The WhisperKOOL Extreme 3500tiR is a fully ducted, self-contained wine cellar cooling system designed for cellars up to 800 cubic feet. It allows installation up to 25 ducted feet away from the wine room and maintains a 55°F cellar temperature with condenser intake air up to 110°F when properly installed.
✔ 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
✘ 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.

Proper installation is critical to performance and warranty protection.
Before selecting this model, confirm:
A heat load calculation has been performed.
The cellar has continuous insulation and vapor barrier.
Duct runs do not exceed 25 equivalent feet.
Condenser intake air remains within specified limits.
A dedicated 115V, 20-amp circuit is available.
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.
