Unmatched Performance for the Most Demanding Wine Cellars
The WhisperKOOL Extreme Series is engineered for one purpose: to deliver uncompromising cooling performance in the most challenging environments. Whether you're building a wine cellar in a garage, basement, or hot climate region, Extreme units offer rugged durability, flexible installation options, and consistent temperature control up to 55°F above ambient temperature.
If your wine collection is an investment, the WhisperKOOL Extreme Series is your insurance policy.
What Makes the WhisperKOOL Extreme Series Different?

- Available in 3500ti, 5000ti, and 8000ti models
- Operates in extreme heat or cold—up to 110°F ambient
- Through-the-wall or fully ducted installation
- Quiet condenser technology
- Advanced digital controller with humidity display
