Extreme ti 8000 – Through-the-Wall Wine Cellar Cooling System

The WhisperKOOL Extreme ti 8000 is a powerful, high-performance wine cellar cooling system designed for through-the-wall installation in small to mid-sized wine cellars. This self-contained unit provides advanced climate control to maintain optimal temperature and humidity for long-term wine storage.

Unlike the tiR version, the Extreme ti 8000 cooling unit features a front-facing digital controller and display, requiring you to enter the cellar to monitor and adjust climate settings. This design offers a user-friendly interface and straightforward temperature and humidity management.

For exterior installations, it is strongly recommended to pair the unit with an exterior housing or grille to protect against weather conditions such as rain, snow, and extreme heat or cold. This protective housing enhances system durability and ensures consistent, efficient operation outdoors. For interior wall installations, the Condenser Ducting Plenum Kit allows hot exhaust air to be redirected, offering greater flexibility and maintaining proper airflow within the cellar space.

Engineered for quiet operation, long-term reliability, and efficient cooling performance, the WhisperKOOL Extreme ti 8000 is the ideal solution for serious wine collectors and cellar builders. With its combination of robust airflow, durable construction, and simple installation, it delivers dependable cooling without compromising your cellar’s acoustics or design.
