WhisperKOOL Extreme 3500tiR Through-the-Wall Wine Cellar Cooler
A self-contained, through-the-wall cooler with variable-speed fans for cellars up to 800 cu. ft. — duct-ready if your needs change later.
Extreme 3500tiR Through-the-Wall Key Features & Benefits
Through-the-Wall, Self-Contained
The 3500tiR mounts directly through the cellar wall as a single self-contained unit — no separate condenser to place or field-charge.
Variable-Speed Fan Technology
Variable-speed fans modulate to match demand, lowering noise and improving efficiency versus fixed-speed systems.
Liquid-Temperature Bottle Probe
The digital control reads the true temperature of your wine, not just the air, keeping the cellar at proper aging conditions.
Dual-Refrigerant Ready
Built for R-134a / R-513a, aligning with current lower-GWP refrigerant standards.
Flexible Power
Runs on a standard 115V, 20-amp dedicated circuit (230V subject to availability).

Where It Fits in the Range
The through-the-wall Extreme tiR line covers cellars up to 800 cu. ft. (3500tiR), 1,250 cu. ft. (5000tiR), and 2,000 cu. ft. (8000tiR). A fully ducted version of each is also available. Confirm sizing with a heat-load calculation before ordering.
A Note on Sizing
The cellar-size rating assumes a fully insulated room with a complete vapor barrier. Design factors such as glass walls, stone or concrete, high ambient temperatures, frequent door openings, or in-cellar lighting can increase the cooling load. When in doubt, choose the next capacity up — an undersized unit can run continuously, fail to reach temperature, and is not covered under warranty. We're happy to help you run the numbers.
Installation & Setup
The Extreme tiR through-the-wall is a self-contained unit — one piece, no separate condenser. Plan the wall opening, a dedicated circuit, and exhaust-side ventilation before installation.
Pre-Installation Requirements
- Fully insulated cellar with a complete vapor barrier (min. R-19)
- Dedicated 115V, 20-amp circuit
- Through-the-wall opening sized for the unit
- Adequate ventilation on the condenser/exhaust side
- 1/2" ID drain line routed to a suitable drain
Placement & Airflow
- Mount so the exhaust side has free airflow and can dump heat
- Keep the exhaust space ventilated and unobstructed
- Do not recirculate exhaust air back to the intake
- Allow service clearance around the unit
Cellar Design Best Practices
- Maintain consistent insulation and seal all air leaks
- Complete the vapor barrier on the warm side of the insulation
- Install a properly weatherstripped cellar door
- Plan rack layout for good air circulation
Maintenance
- Keep condenser coils clean and clear of debris
- Check the digital controller and bottle probe periodically
- Inspect the drain line for free flow
- Schedule an annual professional inspection
