WhisperKOOL Platinum Mini Split Ductless Cooling System 220V High Efficiency

What This Cooling System Is Designed For

The WhisperKOOL Platinum Mini Split 220V High Efficiency is a ductless split wine cellar cooling system designed for properly constructed residential wine cellars up to 500 cubic feet.

It is best suited for:

• Small custom wine rooms
• Fully insulated cellars with a vapor barrier
• Residential installations
• Projects requiring quiet operation
• Applications where remote condenser placement is preferred

This system is engineered to maintain stable 55°F storage conditions when installed in a correctly built enclosure.

Other Sizes: WhisperKOOL Platinum Split 4000 220V H.E. for 1000 cu.ft. wine cellar, 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.

When This Unit Is Not Appropriate

This system may not be suitable if:

• The cellar exceeds 500 cubic feet
• The room includes large glass walls without a heat load calculation
• Insulation or vapor barrier is missing or improperly installed
• The project is commercial or high-traffic
• The condenser location lacks proper ventilation

If your cellar includes stone, concrete, exterior walls, or significant glass exposure, a professional heat load calculation should be performed before selecting this unit.

Undersizing a cooling system can result in continuous runtime, inability to maintain temperature, and premature compressor failure.

How a Ductless Split Wine Cellar Cooling System Works

The Platinum Mini Split consists of two primary components:

• Evaporator (installed inside or near the cellar)
• Condenser (installed remotely — outdoors, attic, or mechanical space)

The components connect via refrigerant line set.

Separating the condenser from the evaporator reduces noise and heat inside the cellar while allowing flexible installation.

Because this is a ductless system, a visible grille will remain inside the cellar. If a concealed installation is required, a ducted split system may be more appropriate.

Cooling Capacity & Performance

• Recommended Cellar Size: Up to 500 cubic feet*
• BTU/h (60°F condenser air intake): 2101 – 2492 BTU/h
• Operating Range: Designed to maintain 55°F cellar temperature with up to 120°F condenser air intake temperature
• Noise Level: Approximately 42–46 dBA

*Capacity assumes a fully insulated, sealed enclosure with properly installed vapor barrier. Cooling capacity decreases as condenser air intake temperature increases.

Understanding Sensible vs Total BTU

• Total BTU includes both temperature reduction and humidity removal.
• Sensible BTU measures temperature reduction only.

In humid climates, total BTU capacity is critical for maintaining proper wine storage conditions.

High-Efficiency 220V Condenser

The 220V high-efficiency configuration:

• Uses significantly less energy than lower-voltage alternatives
• Performs in extreme outdoor temperatures (-20°F to 120°F condenser intake)
• Supports long-term operational stability

Proper condenser ventilation is required to achieve rated performance.

Installation Requirements

Professional HVAC-R installation is required.
Failure to use a qualified installer will void the manufacturer warranty.

Electrical Requirements

• 220V dedicated circuit required
• 15-amp breaker
• Dedicated line (no shared load)

Line Set & Placement

• Condenser may be installed up to 100 line feet from evaporator
• Refrigerant charge adjustments required for extended line lengths
• Proper clearance and ventilation required at condenser

Drain Line

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

Construction Requirements

• Fully insulated enclosure
• Properly installed vapor barrier
• Airtight construction
• No uncontrolled air infiltration

Improper construction significantly reduces cooling performance.

Control & Monitoring Features

KDT Digital Touch Display

• Install up to 50 ft away
• System protection alerts
• Real-time monitoring

Liquid Temperature Bottle Probe

• Measures liquid temperature instead of ambient air
• Improves storage accuracy
• Reduces short cycling

Optional 24V Thermostat Conversion Kit

Allows integration with third-party smart thermostats.

Important:

• Smart thermostat not included
• Bottle probe and standard controller removed if conversion selected
• WhisperKOOL does not provide support for third-party thermostats

Final Recommendation

The WhisperKOOL Platinum Mini Split 220V High Efficiency is ideal for properly constructed small residential wine cellars where quiet operation, energy efficiency, and flexible condenser placement are priorities.

If there is uncertainty regarding insulation quality, climate exposure, or glass content, a professional heat load calculation should be completed before purchase.
