For wine cellars up to 1,000 cu. ft. Fully ducted split system design Remote condenser placement up to 100 ft. Very quiet wine room operation KDT Digital Touch Display Professional HVAC-R installation required Installation Notice: A qualified HVAC-R technician is required for installation of the WhisperKOOL Platinum Split 4000 Ducted System. Failure to follow this requirement may void the manufacturer warranty. Quick Answer Summary Product Type Fully ducted split wine cellar cooling system Recommended Cellar Size Up to approximately 1,000 cu. ft. when properly insulated and sealed BTU/h Range 3,210-4,096 BTU/h estimated range Installation Professional HVAC-R installation required Cooling Configuration Split evaporator and condensing unit with ducted airflow Remote Condenser Placement Up to 100 ft. away Controller KDT Digital Touch Display Temperature Monitoring Liquid-measuring bottle probe Warranty Limited 2-year parts and labor warranty Expert Overview The WhisperKOOL Platinum Split 4000 is built for wine collectors, luxury homeowners, designers, and builders who need reliable wine cellar cooling without placing bulky equipment inside the finished cellar space. Because the evaporator and condensing unit are separated, the louder condenser can be installed remotely while ducting delivers conditioned air to the cellar. This makes the Platinum Split 4000 a strong choice for glass wine walls, contemporary wine rooms, custom residential cellars, and projects where quiet operation and clean visual design are priorities. This unit is best used in a properly insulated and sealed wine cellar with a correct vapor barrier. Glass, concrete, stone, poor insulation, high ambient temperatures, and frequent door openings may increase cooling load and require a larger system. Recommended For Luxury residential wine cellars Glass wine wall installations Serious wine collectors Quiet living spaces near wine rooms Interior designers who need hidden equipment Custom builders planning premium cellar installations Projects with a suitable remote condenser location Not Recommended For Small wine cabinets DIY installation projects Temporary wine storage rooms Uninsulated rooms or unfinished spaces Projects without access to an HVAC-R technician Installations where condenser placement is not possible Free Wine Cellar Design Assistance Need help confirming system sizing? Wine Coolers Empire can review cellar size, insulation, vapor barrier quality, glass exposure, ducting, condenser placement, and cooling capacity before purchase. Call +1-888-407-7770 Email Cooling Specialists Request Expert Help Why Choose the WhisperKOOL Platinum Split 4000? Fully Ducted Design The ducted configuration helps keep equipment hidden from view, preserving the finished appearance of a luxury cellar. Quiet Split Configuration The condenser can be placed away from the cellar to reduce operating noise in the wine room. Remote Condenser Flexibility The condensing unit may be placed up to 100 ft. away, giving installers more flexibility during design and construction. Bottle Probe Monitoring The bottle probe measures liquid temperature for a more accurate reflection of actual wine storage conditions. KDT Digital Touch Display The KDT display can be installed up to 50 ft. away and includes system alerts for operating protection. Optional Upgrade Paths Compatible upgrade options include UV-C light technology, protective condenser housing, coil coating, and 24V thermostat conversion. Advantages and Limitations Advantages Why It Matters Hidden ducted installation Supports clean wine cellar aesthetics and modern design requirements. Quiet operation Helps reduce equipment noise inside the finished cellar. Remote condenser placement Allows more flexible mechanical planning in custom homes. Liquid temperature monitoring Provides more accurate wine temperature readings than air-only monitoring. Optional accessories Allows added protection and performance upgrades based on project conditions. Limitations What to Consider Professional installation required This is not a plug-and-play unit and must be installed by a qualified HVAC-R technician. More complex installation Requires refrigeration lines, ducting, condensate management, electrical work, and commissioning. Proper cellar construction required Poor insulation, heavy glass, or missing vapor barrier can increase cooling demand. Condenser location must be planned The project needs a suitable remote condenser location with proper service access. Installation Requirements The WhisperKOOL Platinum Split 4000 requires professional HVAC-R installation. The system involves refrigerant line connections, ductwork, electrical connections, condensate drainage, and startup commissioning. Required Installation Items Qualified HVAC-R technician required Refrigeration line installation required Proper duct sizing and routing required Condensate drainage planning required Electrical connection required Remote condenser placement required Cellar Construction Needs Proper insulation and vapor barrier strongly recommended Sealed wine cellar envelope required for stable performance Glass-heavy rooms should receive a cooling load review Stone, concrete, and exterior walls may increase heat load Frequent door openings may require additional capacity Key Product Images and Feature Details KDT Digital Touch Display The KDT Digital Touch Display can be installed up to 50 ft. away from the unit and includes Advanced System Protection with alarms when operating parameters are not met. Bottle Probe The included bottle probe measures liquid temperature, giving a more accurate reflection of wine temperature than ambient air measurement alone. Ducting Options The fully ducted configuration allows the system to be placed out of sight while reducing noise inside the cellar.

Glass, stone, concrete, poor insulation, inadequate vapor barrier, high ambient temperature, and frequent door openings can increase cooling demand. Cellar Sizing Guidance The Platinum Split 4000 is generally suitable for wine cellars up to approximately 1,000 cubic feet when the room is properly constructed for wine storage. Cubic footage alone does not determine the correct cooling system. Cooling load may increase when a cellar includes glass walls, stone surfaces, concrete, poor insulation, high surrounding temperatures, frequent door openings, or lighting that adds heat. Choosing an undersized unit may result in poor temperature control, excessive system runtime, premature equipment failure, and difficulty maintaining the desired wine cellar temperature.
