WhisperKOOL Platinum Split 4000 Ductless Cooling System 220V High-Efficiency

For Fully Sealed Wine Cellars Up to 1,000 Cu. Ft. Requiring Remote Condenser Placement

The WhisperKOOL Platinum Split 4000 220V High-Efficiency Ductless Cooling System is designed for fully insulated and vapor-barrier-sealed wine cellars up to 1,000 cubic feet that require quiet operation and flexible condenser installation up to 100 line feet away.

This model is best suited for:

• Modern glass wine walls (properly insulated)
• Interior wine rooms
• Projects requiring outdoor or attic condenser placement
• Installations where interior noise must be minimized
• Cellars with 220V electrical availability

If your cellar exceeds 1,000 cu. ft. or has heavy glass exposure without insulation, a larger model or engineered load calculation is required.

Available in WhisperKOOL Platinum Split 4000 Ductless Cooling System 110V & Platinum Split 4000 Ductless Cooling System 220V for 1000 cu.ft.

Other Sizes: WhisperKOOL Platinum Mini Split 220V H.E. for 500 cu.ft. wine cellar, WhisperKOOL Platinum Split 8000 220V H.E. for 1750 cu.ft wine cellar, and WhisperKOOL Platinum Split Twin for 3000 cu.ft. 220V H.E. wine cellar.

Who This System Is For

Choose the Platinum Split 4000 220V if:

• Your cellar is fully insulated and sealed
• A proper 6-mil vapor barrier (minimum) is installed
• The cellar volume does not exceed 1,000 cubic feet
• You want the condenser installed remotely (garage, attic, exterior)
• You need quieter operation than self-contained units provide
• You have access to a 220V dedicated circuit for the condenser

When This System Is NOT Appropriate

This unit should NOT be selected if:

• The cellar lacks a vapor barrier
• Insulation does not meet recommended R-values (R-19 walls / R-30 ceiling minimum typical guideline)
• The space exceeds 1,000 cu. ft. without a heat load calculation
• The condenser will operate in ambient air exceeding 120°F
• Installation will not be performed by a licensed HVAC-R technician

Improper installation or environmental conditions can result in condensation issues, insufficient cooling, or voided warranty coverage.

How the Platinum Split 4000 Works

This is a ductless split system, meaning:

• The evaporator unit is installed inside or near the cellar.
• The condenser unit is installed remotely (up to 100 line feet away).
• Refrigerant lines connect both components.
• Heat is removed from the cellar and rejected at the condenser location.

Because the condenser is separated from the cellar, interior noise and heat buildup are significantly reduced.

Cooling Performance

Performance values assume a fully insulated and sealed cellar with proper vapor barrier installation.

BTU Output Based on Condenser Air Intake Temperature

Why this matters: As condenser intake temperature increases, cooling capacity decreases. Condensers installed in hot attics or enclosed garages must have proper ventilation.

Optional Accessories

UV-C Light Technology

Enhances air quality and system cleanliness.
(Not available on Mini models.)

Exterior Protective Housing

Galvanized steel housing protects condenser from weather exposure.

Condenser Coil Coating

Recommended for coastal environments to prevent salt air corrosion.

Installation Requirements

• Licensed HVAC-R technician required
• Dedicated electrical circuits for evaporator and condenser
• Proper vapor barrier installation
• Fully insulated walls and ceiling
• Adequate condenser ventilation
• Heat load calculation strongly recommended before purchase

Each wine cellar has unique thermal conditions. Oversizing or undersizing a system can affect humidity control and system longevity.

Comparison Within the Platinum Split Series

If your cellar exceeds 1,000 cu. ft., consider the Platinum Split 8000 or Twin 9000 models.
