WhisperKOOL Ceiling Mount 4000 220V High Efficiency Ductless Split Wine Cellar Cooling System

WhisperKOOL Ceiling Mount 4000 220V High Efficiency Ductless Split Wine Cellar Cooling System

The WhisperKOOL Ceiling Mount 4000 220V High Efficiency Ductless Split System is engineered to deliver effective and dependable cooling for wine cellars up to approximately 1,000 cubic feet when properly insulated and sealed with a vapor barrier. Featuring a ceiling‑mounted evaporator and a remote condenser, this ductless split design keeps the cellar environment quiet and unobtrusive while providing consistent cooling performance. 

This high‑efficiency 220V system boosts energy performance and reduces operating noise compared with standard voltage models, making it an excellent choice for residential or light commercial wine rooms where comfort and discretion matter. The evaporator is mounted flush in the ceiling to optimize usable wall space for racking and storage. 

Temperature control is precise and user‑friendly with the included KDT digital touch display, which can be mounted up to 50 feet away for convenient monitoring and adjustment. An optional liquid‑temperature bottle probe is available to measure the actual wine temperature for improved cellar accuracy. 

Installation is designed to be flexible for custom cellar layouts, with remote condenser placement up to 100 feet away and professional HVAC‑R installation recommended to ensure optimal performance. The WhisperKOOL Ceiling Mount 4000 combines efficient operation with quiet performance to help protect and preserve wine collections. 

It is best suited for homeowners who want:

• A flush ceiling-mounted evaporator
• A remote condenser (split system configuration)
• Quiet operation inside the cellar
• Clean wall space without through-wall equipment

Proper insulation, vapor barrier installation, and a heat load calculation are required to ensure performance.

NOTE: A qualified HVAC-R technician is required for the installation of your WhisperKOOL Ceiling Mount 4000 220V. Failure to adhere to this requirement will void the warranty.

Who This System Is Designed For

The Ceiling Mount 4000 is appropriate when:

• The cellar does not exceed 1,000 cubic feet
• Walls are insulated (recommended minimum R-19)
• Ceiling is insulated (recommended minimum R-30)
• A continuous vapor barrier is installed
• The condenser intake air does not exceed 120°F
• A dedicated 220V circuit is available
• Installation is performed by a qualified HVAC-R technician

When installed correctly, this system can maintain a 55°F cellar temperature for long-term wine storage.

When This System May Not Be the Right Choice

You may require a larger or different cooling system if:

• The cellar exceeds 1,000 cubic feet
• The space includes large glass walls or doors
• Insulation is insufficient or inconsistent
• A vapor barrier is missing
• The environment is commercial or high traffic
• The condenser space regularly exceeds 120°F
• Heat load calculations indicate higher BTU demand

In these cases, the Ceiling Mount 8000 or Twin models may be more appropriate.

Cooling Performance & Capacity

• Cooling output varies depending on condenser intake temperature and fan speed.

At 60°F Condenser Air Intake

• Medium: 4,871 / 5,430 BTU/h (Sensible/Total)
• High: 5,324 / 6,087 BTU/h

At 75°F Condenser Air Intake

• Medium: 4,752 / 5,291 BTU/h
• High: 5,198 / 5,914 BTU/h

At 85°F Condenser Air Intake

• Medium: 4,631 / 5,147 BTU/h
• High: 4,945 / 5,351 BTU/h

Performance decreases as condenser air temperature rises. Maintaining a controlled mechanical room environment improves system efficiency and longevity.

Installation Overview

Split System Configuration

• Evaporator installs flush between ceiling joists inside the cellar
• Condenser installs remotely (up to 100 line feet away)
• Reduces mechanical noise inside the cellar
• Preserves wall space and aesthetics

Drain Line

• 1/2" ID clear plastic tubing (not included)

Professional Installation Required

• A qualified HVAC-R technician must perform installation. Failure to use professional installation voids the warranty.

Temperature Control & Monitoring

Bottle Probe Technology

The liquid-temperature bottle probe measures actual wine temperature instead of ambient air temperature.

This provides:

• Improved temperature stability
• Reduced short cycling
• More accurate long-term aging conditions

Advanced Digital Display

• Digital touch control
• 50 ft. communication cable
• System protection alarms
• Real-time monitoring

Optional 24V Thermostat Conversion Kit

An optional 24V conversion kit allows connection to a customer-supplied thermostat.

Important considerations:

• The standard WhisperKOOL control and bottle probe are removed when using 24V mode.
• WhisperKOOL does not provide smart thermostats.
• Technical support does not cover third-party thermostat issues.

This option is intended for users integrating cellar cooling into home automation systems.

Ceiling Mount 4000 vs 8000 – Which Should You Choose?

If your cellar approaches 1,000 cubic feet or includes glass or elevated ambient temperatures, sizing up may prevent performance issues.

Professional Sizing Recommended

Every wine cellar has unique construction variables. Before selecting a cooling system, a heat load calculation should be performed to confirm capacity requirements.

If you are unsure whether the Ceiling Mount 4000 is appropriate for your space, professional consultation is recommended prior to purchase.
