Product Overview
The WhisperKOOL Extreme 3500tiR Fully Ducted Wine Cellar Cooling System is designed for collectors, builders, designers, and homeowners who want dependable cellar climate control without visible cooling equipment inside the wine room. Its fully ducted configuration allows the unit to be installed remotely while delivering conditioned air into the cellar through ductwork.
This makes the Extreme 3500tiR especially useful for luxury wine cellars, custom residential wine rooms, and designer-led projects where appearance, quiet operation, and long-term wine preservation matter. The system includes an advanced digital controller, liquid-temperature-measuring bottle probe, variable-speed fan capability, and duct plenums for flexible installation.
The Extreme 3500tiR is rated for wine cellars up to approximately 800 cubic feet when the room is properly insulated, sealed, and constructed with a correct vapor barrier. Because every wine cellar has unique cooling requirements, Wine Coolers Empire recommends confirming the heat load before selecting any cooling unit.

BTU/h & Sizing Notes
The WhisperKOOL Extreme 3500tiR is rated at 2688 BTU/h. This value is an estimate and should not be treated as a universal guarantee for every cellar. Wine cellar cooling demand can change based on insulation quality, vapor barrier construction, glass exposure, stone or concrete surfaces, ceiling height, ambient temperature, and door usage.
Choosing an undersized cooling unit may prevent the cellar from reaching the desired storage temperature and may increase system wear. For guidance on wine cellar construction, review our wine cellar insulation guide and ideal wine cellar temperature guide.

Please note: WhisperKOOL does not provide smart thermostats. If the 24V thermostat conversion kit is selected, the system will not be built with the standard WhisperKOOL control or liquid-measuring bottle probe. A compatible 24V smart thermostat must be purchased separately.
Optional Accessories
Condenser Coil Coating
Condenser coil coating is a protective option designed to help protect the condenser coil from salt air and corrosive environments. It is especially useful for coastal homes, beach properties, and humid environments where salt exposure may shorten equipment lifespan.
Wine Coolers Empire recommends the WhisperKOOL Extreme 3500tiR for collectors building dedicated wine cellars up to approximately 800 cubic feet where quiet operation, hidden equipment placement, and refined cellar aesthetics are priorities.
This model is especially well suited for luxury residential wine rooms, custom builder projects, and designer-led installations where a visible through-the-wall unit would interrupt the look of the space.
Consider stepping up to the WhisperKOOL Extreme 5000tiR if your cellar includes extensive glass, high ceilings, stone or concrete construction, elevated ambient temperatures, frequent door openings, or a cooling load that exceeds the 3500tiR rating.

You can fully duct both the evaporator and the condenser. The recommended duct run is up to 25 feet for either supply or return.
It includes a 3‑speed fan switch, allowing you to adjust the fan speed and balance noise versus performance.
Temperature is managed via a remote digital controller with a long cable, and the system uses a liquid‑temperature bottle probe to measure wine temperature accurately.
The unit runs on 115 V and requires a dedicated 20‑amp circuit for safe operation.
It uses a 3/8‑inch ID clear plastic tubing drain line to remove moisture generated during operation."]
