Through-the-Wall Cooling System for Wine Cellars up to 800 cu. ft.
Standalone Overview
The WhisperKOOL Extreme 3500tiR is a self-contained, through-the-wall wine cellar cooling unit designed for fully insulated and sealed residential wine rooms up to 800 cubic feet. It can maintain a stable 55°F cellar temperature in environments where condenser intake temperatures reach up to 110°F, provided proper ventilation and insulation standards are met. This model includes a remote-mounted digital controller with bottle probe for precise liquid temperature monitoring.
Mechanical spaces exceeding 110°F intake temperature
Rooms without a proper vapor barrier
If your cellar exceeds 800 cu. ft., consider the Extreme 5000tiR.
Core Performance Features
Through-the-Wall Installation
The 3500tiR is engineered to fit between standard wall studs, allowing direct installation with minimal structural modification when framing is appropriate.
Variable-Speed Fan System
The 3-speed fan configuration improves air circulation and temperature stability under varying heat loads. This reduces short cycling and supports long-term system durability.
High-Temperature Tolerance
The unit is capable of maintaining a 55°F cellar temperature when condenser intake air reaches up to 110°F. This makes it suitable for installations in garages, mechanical rooms, and hot climate regions—provided adequate ventilation is available.
Remote Platinum Series Digital Controller
50-ft. communication cable
External mounting capability
Advanced System Protection alerts
Bottle probe compatibility
Precise digital temperature adjustment
Remote placement allows temperature monitoring without entering the cellar, reducing environmental disruption.
Liquid-Temperature Measuring Bottle Probe
Unlike ambient air sensors, the bottle probe measures actual liquid temperature. This produces more stable and accurate wine storage conditions.
Condenser-Side Ducting Capability
The condenser side can be ducted to redirect hot exhaust air when installation conditions require it.
Ducting components are sold separately. Maximum duct length and airflow resistance must comply with manufacturer specifications to prevent reduced performance.

Manuals for WhisperKOOL Extreme 3500tiR Self-Contained:
At 85°F condenser intake temperature, the 3500tiR delivers approximately 3175 BTU/h of cooling capacity.
This output is appropriate for a sealed 800 cu. ft. cellar with:
Standard insulation levels
Minimal glass surfaces
Limited door cycling
Controlled ambient conditions
Cellars with significant glass, stone, or high ceilings may require a higher-capacity unit.
Installation Requirements (Critical for Performance)
Proper installation is essential for system reliability.
Minimum recommendations:
R-19 wall insulation
R-30 ceiling insulation
Vapor barrier on warm side of insulation
Dedicated 20-amp electrical circuit
Adequate condenser ventilation space
Gravity drain slope or condensate pump
Failure to meet insulation and ventilation standards may prevent the system from reaching target temperature.
Exterior Wall Installation Guidance
When installing through an exterior wall:
An exterior grille is strongly recommended to protect against weather exposure.
Intake temperature must not exceed 110°F.
Proper flashing and moisture protection must be implemented.
Optional 24V Thermostat Conversion
The 3500tiR supports a 24V thermostat conversion kit for integration with third-party smart thermostats.
Important:
WhisperKOOL does not provide smart thermostats.
The factory digital controller and bottle probe are removed when converting.
Manufacturer support does not extend to third-party thermostat troubleshooting.
When to Consider a Larger Model
Upgrade to the Extreme 5000tiR if:
Cellar exceeds 800 cu. ft.
Significant glass exposure exists
High ceiling height increases volume
Ambient heat load is elevated
Heat load calculations are recommended prior to final unit selection.

Final Summary
The WhisperKOOL Extreme 3500tiR is engineered for sealed, insulated residential wine cellars up to 800 cubic feet requiring reliable 55°F storage—even in warmer installation environments.
With variable-speed airflow, high-temperature tolerance, remote digital control, and condenser-side ducting flexibility, it is designed for installations where environmental control and reliability are critical.
For larger or glass-heavy cellars, consider stepping up to the Extreme 5000tiR.
I have used this cooling system for over a year - it is great!

I use this product every day to keep my wine bottles chilled at the right temperature. I like the digital thermostat as well as the digital humidity gauge. It's pretty quiet and easy to maintain. The automatic timer is very convenient, too.

Excellent customer service
I have to admit that I was a little concerned about buying a wine cooler online but this company is amazing. With their great prices they also offer top notch service. They went above and beyond what I was expecting. I had a question and they got right back to me.

Best Buy
I have been a wine enthusiast for as long as I can remember. The only problem I always faced is that every time I drink wine, it lost its taste after two days. It's because of my lack of knowledge about wine cellars. It was last year when I visited a friend's house and he had an amazing collection of wines. He told me that he stores the wine in the cellar that is temperature-controlled by Whisperkool 3500tir . I was really surprised to know so I purchase my own 3500tir wine cooling unit in Wine Cellar Authority. Their reps are friendly. Thumbs up!

Quality wine cooling unit
I've been using this unit for about 2 months now, I can't believe how easy it is to use, and how quiet it runs. The remote control makes it much easier than fiddling around with the front panel. I can't believe I waited this long to get myself a wine cooler.
