WhisperKOOL Platinum Split 4000 Ducted Cooling System 220V High Efficiency

Is the WhisperKOOL Platinum Split 4000 (220V) the right cooling system for my 1,000 cubic foot wine cellar?

The WhisperKOOL Platinum Split 4000 (220V High Efficiency) is a ducted split-system wine cellar cooling unit designed for properly insulated cellars up to 1,000 cubic feet.

It separates the evaporator (inside or ducted to the cellar) from the condenser (installed remotely), significantly reducing noise inside the wine space while preserving design flexibility.

Professional HVAC-R installation is required.

Available in WhisperKOOL Platinum Split 4000 110V Condenser & Platinum Split 4000 220V Condenser for 1000 cu.ft.

Other Sizes: WhisperKOOL Platinum Split 8000 220V H.E. for 1750 cu.ft wine cellar and WhisperKOOL Platinum Split Twin 220V H.E. for 3000 cu.ft. wine cellar.

Best For

This system is appropriate if:

• Your cellar measures 800–1,000 cu. ft.
• Walls and ceiling meet recommended insulation values (R-19 walls minimum)
• A continuous vapor barrier is installed
• You want equipment hidden from view
• The condenser can be installed up to 100 line feet away
• You have access to a licensed HVAC technician
• Ambient condenser temperatures may reach up to 120°F

Common use cases:

• Glass wine walls
• Modern residential cellars
• Luxury dining room displays
• Small commercial wine rooms

Not Ideal For

This system may underperform or be inappropriate if:

• The cellar exceeds 1,000 cu. ft.
• The space lacks a vapor barrier
• Insulation is insufficient
• The room is open to other living areas
• There is no ability to run a dedicated 220V circuit
• Excessive glass exposure exists without heat load review

A professional heat load calculation is strongly recommended before purchase.

How the System Works

The Platinum Split 4000 is a ducted split system:

• The evaporator installs inside or ducted to the wine cellar.
• The condensing unit installs remotely (garage, mechanical room, exterior, etc.).

Because the compressor is located outside the cellar, internal noise and vibration are minimized.

The ducted design allows the evaporator to remain concealed for architectural wine displays.
