WhisperKOOL Platinum Split 4000 Ducted Wine Cellar Cooling System

Is the WhisperKOOL Platinum Split 4000 the Right Cooling System for Your Wine Cellar?

The WhisperKOOL Platinum Split 4000 is a professional-grade ducted split wine cellar cooling system rated for cellars up to approximately 1,000 cubic feet when properly insulated and vapor sealed. With 3120 BTU/h cooling capacity and remote condenser placement, it provides quiet, flexible cooling for permanent residential wine cellars.

Note: Updated Replacement: Copeland 115V to WhisperKool Ducted Platinum Split 4000 OMEGA 110V Wine Cooling System and 220V High Efficiency WhisperKOOL Platinum Split 4000 Ducted Cooling System 

Other Sizes: WhisperKOOL Platinum Split 8000 for 1750 cu.ft wine cellar and WhisperKOOL Platinum Split Twin for 3000 cu.ft. wine cellar.

Is the Platinum Split 4000 Right for Your Cellar?

This system is appropriate if:

• Your cellar is ≤ 1,000 cubic feet
• Walls are insulated to minimum R-19
• Ceiling is insulated to minimum R-30
• A continuous 6-mil vapor barrier is installed
• The door is sealed and insulated
• You have space for remote condenser placement
• You can use a licensed HVAC installer

This system is not appropriate if:

• The room is unfinished or uninsulated
• The vapor barrier is missing
• The cellar exceeds 1,000 cubic feet
• You want a plug-and-play DIY system
• Proper drainage cannot be installed

Improper installation or inadequate insulation will cause continuous runtime and may shorten compressor life.

Cooling Capacity & Performance

Rated Cellar Size

Approximately 1,000 cubic feet

Cooling Capacity

3120 BTU/h
(Tested with 85°F air entering condenser coil)

Temperature Performance

Designed to maintain 55°F cellar temperature
Supports condenser air intake temperatures up to 110°F

Actual performance depends entirely on heat load, insulation quality, glass exposure, and ambient conditions. A professional heat load calculation is recommended before purchase.

How the Split System Works

The system separates cooling into two components:

Model 4000 Evaporator (Fan Coil Unit)

• Installed inside or near the cellar
• Circulates cooled air through ducting
• Includes 50-ft digital thermostat cable
• Includes 50-ft liquid temperature bottle probe

The bottle probe measures wine temperature rather than just air temperature for more accurate control.

4000 Air-Cooled Condensing Unit

• Installed remotely (garage, mechanical room, or approved exterior location)
• Removes heat from the system
• Keeps cellar noise minimal

Because the compressor is not located inside the cellar, the system operates significantly quieter than most self-contained units.

Installation Requirements

This is not a self-contained unit. HVAC installation is mandatory.

Electrical Requirements

• 115V
• 15-amp dedicated circuit (evaporator and condenser)

Line Set Requirements

• Liquid line: 1/4"
• Suction line:
  • 1/2" for runs under 50 ft.
  • 5/8" for runs over 50 ft.

Maximum Distance Limits

• Condenser: up to 100 line feet from evaporator
• Evaporator: up to 25 duct feet from cellar

Exceeding manufacturer distance limits reduces efficiency and may void warranty.

Ducting Specifications

• 8" supply duct
• 10" return duct
• Duct plenum configuration required

Incorrect duct sizing increases static pressure and reduces cooling performance.

Drain Requirements

• 1/2" ID clear plastic tubing (not included)
• Proper slope required
• Drain line must not trap water

Improper drainage can cause moisture buildup and system damage.

When to Choose This System

Choose the Platinum Split 4000 if:

• You want minimal noise inside the cellar
• You have a mechanical room or remote condenser location
• You are building a permanent insulated cellar
• You need ducted airflow flexibility
• Your cellar heat load fits within 3120 BTU/h

When to Consider a Larger System

You may need a higher-capacity model if:

• The cellar exceeds 1,000 cubic feet
• You have significant glass exposure
• The room shares exterior walls
• Ambient temperatures are extreme
• Insulation levels are below recommended minimums

Undersizing can lead to continuous runtime and premature compressor wear.

Important Sizing Notice

Each wine cellar is unique. Glass, lighting, exterior exposure, and door construction all affect heat load.

A professional heat load calculation should always be performed before selecting a cooling unit.

Final Decision Summary

The WhisperKOOL Platinum Split 4000 is a professional-grade, ducted split cooling system engineered for insulated wine cellars up to 1,000 cubic feet. It delivers quiet performance, remote condenser flexibility, and stable 55°F storage when properly installed and sized.

If you are unsure about sizing, insulation compliance, or installation requirements, consult a cooling specialist before purchase.
