Quick Answer Summary Product Type Ductless split wine cellar cooling system Mounting Style Flush ceiling mount Recommended Cellar Size Up to approximately 1,000 cu. ft. BTU/h 4,000 BTU/h Estimated BTU/h Range 4,000-6,087 BTU/h Evaporator Dimensions 35.75" L x 14.5" W x 12.75" H Condenser Dimensions 16.08" L x 16.23" W x 12.61" H Drain Line 1/4" ID clear plastic tubing, not provided Control KDT Digital Touch Display Warranty Limited 2-year product warranty, parts and labor Product Overview The WhisperKOOL Ceiling Mount 4000 Ductless Split System is built for collectors who want reliable wine cellar cooling without a visible wall-mounted unit. The evaporator mounts flush into the ceiling, draws warm air upward, and circulates cooled air throughout the cellar. Because this is a split system, the condenser is installed remotely from the wine room. This helps reduce mechanical noise inside the cellar and supports a more refined wine room design. Updated design details include bottom-mounted wiring and line-set access, flare fittings that eliminate on-site brazing, e-coated Duramax coils, a redesigned hex mesh grille, and a startup air filter for added system protection. Available configuration: WhisperKOOL Ceiling Mount 4000 220V Condenser. Recommended For Custom residential wine cellars Luxury wine rooms where aesthetics matter Collectors who want discreet ceiling-mounted cooling Properly insulated and sealed cellars up to approximately 1,000 cu. ft. Projects where the condenser can be installed remotely New construction or planned cellar remodels Not Recommended For DIY installations Uninsulated rooms or spaces without a vapor barrier Cellars larger than 1,000 cu. ft. without professional sizing review Temporary wine storage areas Projects without ceiling access for installation and service Applications where a self-contained plug-and-play unit is preferred Free Wine Cellar Design Assistance Wine Coolers Empire can help confirm cellar size, insulation, vapor barrier quality, ceiling access, condenser placement, and system fit before purchase. Request Free Wine Cellar Design Assistance Call +1-888-407-7770 Key Features Flush Ceiling-Mounted Design The evaporator is designed to mount flush with drywall or sheetrock and fit between ceiling joists for a clean integrated appearance. Ductless Split Performance The split design separates the evaporator from the condenser, moving heat and mechanical noise away from the wine cellar. KDT Digital Touch Display The KDT Digital Touch Display can be installed up to 50 feet away from the unit and includes Advanced System Protection alerts. Liquid Temperature Bottle Probe The included bottle probe measures liquid temperature for a more accurate reflection of wine temperature than ambient air alone. Startup Air Filter The startup air filter helps protect the unit from debris during installation, cellar construction, and rack installation. Optional 24V Thermostat Conversion The optional conversion kit allows the system to work with compatible 24V smart thermostats for Wi-Fi control and monitoring. Feature Images Touch Display The KDT Digital Touch Display provides remote system control and monitoring. Bottle Probe The liquid temperature bottle probe helps monitor the temperature of the wine itself. Air Filter The startup air filter helps protect the unit from construction and installation debris. Advantages and Limitations Advantages Limitations Nearly invisible ceiling-mounted installation Requires professional HVAC-R installation Remote condenser helps reduce cellar noise Requires refrigerant line-set routing Strong fit for luxury cellar designs Requires ceiling access and proper framing Liquid temperature monitoring improves wine protection Not suitable for poorly insulated rooms Optional smart thermostat compatibility Smart thermostat support is not provided by WhisperKOOL Installation Requirements Warranty Requirement: This system must be installed by a qualified HVAC-R technician. Improper installation can void the warranty and may cause performance problems. Required Installation Considerations Ceiling framing and joist spacing must support the ceiling-mounted evaporator. The wine cellar must be fully insulated and sealed. A proper vapor barrier is required for stable cellar performance. Refrigerant line-set routing is required between the evaporator and condenser. Electrical wiring must be completed by a qualified professional. Condensate drainage must be planned before installation. Condenser placement must allow proper ventilation and service access. Drain Line Requirement The WhisperKOOL Ceiling Mount 4000 requires a 1/4" ID clear plastic drain line. Drain tubing is not provided. Confirm drain routing before installation so condensate can be managed properly and service access remains available. BTU/h and Sizing Notes The WhisperKOOL Ceiling Mount 4000 has an estimated cooling range of 4,000-6,087 BTU/h. This value is an estimate and not a guarantee for every 1,000 cubic foot wine cellar. Actual cooling requirements depend on cellar construction, insulation, vapor barrier quality, glass exposure, ambient temperature, door type, and other design variables. Cellars with glass, stone, concrete, poor insulation, or high ambient heat may require a larger system. Choosing an undersized unit can result in excessive runtime, unstable temperature, and premature equipment failure. Request a sizing review before purchase if the cellar has high-load materials or unusual ambient conditions. Learn more about proper cellar insulation: Best Wine Cellar Insulation.
