WhisperKOOL Platinum Split 4000 Ducted Wine Cellar Cooling System
A fully ducted split system for cellars up to 1,000 cu. ft. — the evaporator stays completely out of sight while a remotely mounted, high-efficiency condenser does the work up to 100 feet away.
Platinum Split 4000 Ducted Key Features & Benefits
Fully Ducted, Concealed Design
The evaporator can be installed up to 25 duct feet from the cellar and ducted in, so no equipment is visible inside your wine room. The result is a clean, quiet space with conditioned air delivered through 8" supply and 10" return ducting.
Advanced 220V High-Efficiency Condenser
Oversized condenser coils maintain strong cooling even in hot, humid mechanical rooms, and the 220V high-efficiency design draws roughly 50% less power than a comparable 110V unit. The system can hold a 55°F cellar with condenser air intake temperatures as high as 120°F.
Whisper-Quiet Operation
Large, slow-rotation fans move plenty of air while keeping the condenser around 45 dBA. Direct thermostat-cable communication eliminates pump-down cycling for smoother, quieter runtime.
Precise Digital Control
An advanced digital display (50-ft cable) works with a liquid-temperature-measuring bottle probe, so the thermostat reads the true temperature of your wine rather than the air — protecting your collection from swings.
Cold Weather Start Kit Included
This unit ships with the Cold Weather Start Kit at no extra charge, allowing reliable operation with the condenser exposed to temperatures as low as -15°F.
Optional 24V Smart Thermostat
Prefer smart-home control? An optional 24V thermostat conversion lets your contractor install a Nest, Ecobee, or Honeywell thermostat. Note: choosing this option removes the standard WhisperKOOL control and bottle probe, and the smart thermostat is sourced separately.

Where It Fits in the Range
The Platinum Split 4000 is rated for cellars up to 1,000 cu. ft. and is available as a visible wall-mounted unit or this fully ducted (concealed) version. For larger spaces, step up to the Platinum Split 8000 (up to 1,750 cu. ft.) or the Platinum Split Twin for the largest cellars. Always 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
Professional installation required: WhisperKOOL split systems must be installed by a qualified HVAC/R technician. Installation by anyone other than a licensed HVAC/R technician will void the warranty.
Pre-Installation Requirements
- Fully insulated cellar with a complete vapor barrier
- Evaporator: dedicated 120V, 15-amp circuit
- Condenser: dedicated 220V, 15-amp circuit (or 110V for the OMEGA option)
- Line set sized per run length (not included)
- 8" supply / 10" return duct runs planned
Placement & Distances
- Evaporator ducted up to 25 duct ft from the cellar
- Condenser up to 100 line ft from the evaporator
- Condenser can sit in a mechanical room, basement, garage, or rooftop
- Provide clear airflow around the condenser
- Route a 1/2" ID drain line from the evaporator
Cellar Design Best Practices
- Maintain consistent insulation and seal all air leaks
- Install a properly weatherstripped cellar door
- Complete the vapor barrier on the warm side of the insulation
- 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
