Need Help Confirming the Right Cooling System?
Wine Coolers Empire provides complimentary wine cellar cooling guidance and product-focused wine cellar design planning before purchase.
The WhisperKOOL Platinum Split 4000 is a ductless split wine cellar cooling system built for medium-sized custom cellars where equipment placement, quiet operation, and reliable temperature control matter. In a split system, the evaporator and condensing unit are separated. The evaporator is installed near or inside the wine cellar, while the condensing unit can be placed remotely outdoors, in an attic, utility room, or mechanical space.
This configuration helps reduce noise and heat near the wine room while giving homeowners, designers, and builders more flexibility than a self-contained unit. For projects where the cooling equipment should be fully hidden, consider a ducted split alternative from the WhisperKOOL Platinum Split System collection.
Design Note: A ductless split system includes a visible evaporator grille. If the project requires fully concealed supply and return air, a ducted split wine cellar cooling system may be a better fit.
Why Choose the WhisperKOOL Platinum Split 4000?
Remote Condenser Placement
The condenser can be installed up to 100 line feet away from the evaporator, helping reduce operational noise and heat near the wine cellar.
Ideal for Glass Wine Walls
The ductless split format works well for contemporary display cellars and glass wine walls where flexible equipment placement is needed.
Liquid Temperature Monitoring
The bottle probe measures liquid temperature, giving a more accurate reflection of the wine’s storage condition than ambient air alone.
Advanced Digital Control
The KDT digital touch display can be installed up to 50 feet away from the unit for convenient monitoring and control.
Optional Smart Thermostat Compatibility
With the optional 24V thermostat conversion kit, the system can support compatible third-party smart thermostat control.
Professional-Grade Wine Storage
Designed to maintain cellar conditions appropriate for wine storage when the room is correctly insulated, sealed, and sized.
Buyer Fit by Project Type

Advantages and Limitations
Advantages
Limitations
Remote condenser placement helps reduce noise and heat near the wine room.
Requires professional HVAC-R installation.
Suitable for medium-sized cellars up to approximately 1,000 cu. ft.
Not appropriate for oversized or poorly insulated cellars without further sizing review.
Works well for modern glass wine walls and custom residential projects.
Glass, stone, concrete, sunlight exposure, and poor insulation can increase heat load.
Includes KDT digital display and liquid-temperature-measuring bottle probe.
Visible evaporator grille remains inside or near the wine cellar.
Smart thermostat is not supplied by WhisperKOOL and is not supported by WhisperKOOL customer service.
Installation Requirements
The Platinum Split 4000 is not a plug-and-play wine cellar cooler. It is a split refrigeration system that requires professional installation, refrigerant line set planning, drainage, and electrical coordination.
Installer Requirement
Qualified HVAC-R technician required
Evaporator Location
Installed in or near the wine cellar
Condensing Unit Location
Can be installed outdoors, in an attic, utility room, or mechanical space
Maximum Line Distance
Up to 100 line feet from evaporator to condenser
Drain Line
½" ID clear plastic tubing required; not provided
Line Set
Liquid line 1/4"; suction line 1/2" under 50 ft.; suction line 5/8" over 50 ft.
Do not size by cubic footage alone. Glass walls, poor insulation, sunlight exposure, exterior walls, high ambient temperatures, stone, concrete, and air leaks can increase heat load. Contact Wine Coolers Empire before purchase if your cellar includes these conditions.
Key Features
KDT Digital Touch Display
The KDT Digital Touch Display can be installed up to 50 feet away from the unit. It includes Advanced System Protection with alerts designed to notify users when operating parameters are not being met.
Liquid Temperature Bottle Probe
The bottle probe measures liquid temperature inside the cellar. This helps the system respond to wine storage conditions more directly than ambient air temperature readings alone.

WhisperKOOL Platinum Split Series Customer Review
Ray and Kim from Roseville, California selected a WhisperKOOL Platinum Split System for their modern wine cellar and shared their experience.
Choose the WhisperKOOL Platinum Split 4000 Ductless Cooling System if your project requires a professional-grade cooling solution for a medium-sized, properly insulated wine cellar and you want the condenser placed away from the wine room. It is especially appropriate for glass wine walls, luxury residential wine rooms, and custom projects where quiet performance and precise wine temperature monitoring are important.
Do not choose this unit based on cubic footage alone. If your cellar includes glass, stone, exterior walls, high ceilings, poor insulation, direct sun exposure, or unusual ambient heat, request a sizing review before purchase. In those cases, the correct solution may be a larger Platinum Split model or a ducted split configuration.
