WhisperKOOL Ceiling Mount 4000 Ductless Split Wine Cellar Cooling System

WhisperKOOL Ceiling Mount 4000 Ductless Split Wine Cellar Cooling System

The WhisperKOOL Ceiling Mount 4000 Ductless Split System is a discreet, high‑performance cooling solution specifically designed for wine cellars up to approximately 1,000 cubic feet when the space is properly insulated and sealed with a vapor barrier. Its ductless split configuration separates the ceiling‑mounted evaporator and remote condenser, keeping noise and heat out of the cellar while delivering stable and efficient cooling throughout the space.

This system operates by drawing warm air that naturally rises to the ceiling, cooling it efficiently, and redistributing conditioned air throughout the cellar. The virtually invisible ceiling‑mounted design maximizes usable wall space for wine racking and contributes to a clean, polished cellar aesthetic.

Temperature control is precise and flexible with the included KDT digital touch display, which can be mounted up to 50 feet away, alongside a liquid‑temperature bottle probe that measures wine temperature directly for enhanced accuracy. An integrated air filter helps protect the unit from debris during start‑up or rack installation.

Professional HVAC‑R installation is required to maintain the warranty and ensure optimal performance. With quiet operation, flexible installation, and reliable cooling capacity, the WhisperKOOL Ceiling Mount 4000 is ideal for residential collectors and custom cellar projects.

Is This the Right Cooling System for Your Wine Cellar?

The WhisperKOOL Ceiling Mount Split System is designed for homeowners and contractors who want minimal visual impact with professional-grade cooling performance.

It is best for:

• Modern glass wine walls
• Cellars with limited wall space
• New builds or remodels with ceiling cavity access
• Fully insulated, sealed wine rooms

It is not ideal for:

• Uninsulated basements
• Rooms without a vapor barrier
• DIY installation
• Cellars exceeding 2,000 cubic feet

If your cellar is properly constructed and within capacity range, this system delivers discreet, stable 55°F storage even in warm climates.

4000 vs 8000 — Which Model Do You Need?

*Assumes fully insulated enclosure with proper vapor barrier.

If your cellar includes:

• Large glass panels
• Stone or concrete surfaces
• High ambient exposure
• Poor door sealing

You may require upsizing beyond cubic footage guidelines.

When in doubt, confirm via cooling load evaluation.

How the Ceiling Mount Split System Works

This is a ductless split cooling system:

• The evaporator installs inside the cellar ceiling.
• The condenser installs remotely (garage, attic, utility room, or outdoors with housing).
• Refrigerant lines connect both units (up to 100 line feet).
• No ductwork required.

Because the compressor sits outside the cellar, interior noise is reduced compared to through-the-wall systems.

Performance Capabilities

• Maintains 55°F cellar temperature
• Designed to operate with condenser air intake temperatures up to 110°F
• Suitable for warm-climate installations (with proper ventilation)

CFM: 321
Refrigerant: R-134a

Wine cooling systems are engineered for temperature stability, not rapid cooling like comfort HVAC.

Installation Requirements

Professional HVAC-R installation is required.
Failure to use a licensed technician voids the warranty.

Minimum cellar requirements:

• Full insulation
• Continuous vapor barrier
• Airtight door seal
• Dedicated 115V circuits
• Proper drainage planning

Improper room preparation is the most common cause of system failure.

Technical Specifications

Cooling & Electrical

Dimensions

• Evaporator: 35.75” L x 12.75” H x 14.5” W
• Condenser: 16.08” L x 16.23” W x 12.61” H

Confirm framing depth and service clearance before installation.

Weight

Drainage

¼” ID clear plastic tubing (not included).
Drain slope must be properly pitched to prevent backup.

Line Set Distance

Maximum distance between evaporator and condenser: 100 line feet

Longer runs may affect performance and require professional confirmation.

Thermostat & Monitoring

Includes:

• Advanced digital touch display (50 ft. cable)
• Liquid-temperature bottle probe (50 ft. cable)

The bottle probe measures wine liquid temperature rather than air, improving stability and reducing short cycling.

Best For

• Contemporary residential wine cellars
• Glass wine walls
• Remodels with ceiling access
• Projects prioritizing low visual impact

Not Recommended For

• DIY installers
• Rooms lacking vapor barrier
• Commercial cellars requiring redundancy
• Cellars above 2,000 cu. ft.

Common Installation Mistakes to Avoid

• Skipping vapor barrier
• Installing condenser in unventilated space
• Undersizing for high-glass rooms
• Improper drain slope
• Sharing circuits with other appliances

Wine cooling systems require environmental preparation as much as mechanical installation.

Warranty

Two-Year Limited Warranty (Parts & Labor)
Valid only when installed by licensed HVAC-R technician.

Professional Recommendation

Before purchasing, confirm:

1. Cubic footage
2. Insulation R-value
3. Vapor barrier presence
4. Condenser placement location
5. Electrical availability

Cooling system mis-sizing leads to condensation issues, excessive runtime, and shortened lifespan.
