Premium Ceiling-Mounted Ductless Split Wine Cellar Cooling System
WhisperKOOL Ceiling Mount Twin 9000 Ductless Split System
Ceiling-mounted ductless split wine cellar cooling for fully insulated and properly sealed wine cellars up to approximately 3,000 cubic feet. Its twin evaporator design keeps the cooling unit out of sight while preserving valuable wall and floor space inside the cellar.
Designed for wine cellars up to approximately 3,000 cu. ft.
Ceiling-mounted evaporator keeps the cooling system visually discreet
Ductless split design eliminates the need for duct runs
Available with standard controls or optional 24V thermostat conversion
Professional HVAC-R installation required
Important Installation Notice: A qualified HVAC-R technician is required to install the WhisperKOOL Ceiling Mount Twin 9000. Failure to follow this requirement may void the warranty.
Product Overview
The WhisperKOOL Ceiling Mount Twin 9000 Ductless Split System is built for larger wine cellars where cooling performance, cellar aesthetics, and space efficiency are all priorities. Instead of placing a visible cooling unit on the wall or floor, the evaporator is mounted in the ceiling so the wine cellar remains clean, open, and focused on the wine collection.
This WhisperKOOL wine cooling system draws warmer air from the ceiling area, cools it, and distributes conditioned air throughout the wine room. Because it is a ductless split system, it does not require ductwork, making it a strong choice for custom wine cellars where duct runs are not practical or where a more discreet mechanical layout is preferred.
The redesigned Ceiling Mount platform improves installer accessibility by placing bottle probe wiring, electrical connections, and line set access at the bottom of the unit. It also includes flare fittings that do not require brazing, e-coated Duramax evaporator coils, a hex mesh grille, and an added air filter to help protect the unit during startup and installation.

Free Wine Cellar Design Assistance
Wine Coolers Empire can help review cellar size, ceiling access, insulation, vapor barrier quality, glass exposure, condenser placement, and installation requirements before purchase.
The evaporator is designed to mount flush into the ceiling, keeping the cooling system visually discreet while preserving wall space for wine racks, displays, and cellar finishes.
Dual Evaporator Cooling
The Twin 9000 uses dual evaporators to support larger wine cellar capacities where a single smaller ceiling-mounted system may not be sufficient.
Ductless Split Configuration
The ductless split design places the condenser away from the cellar and does not require duct runs, helping simplify design planning where ductwork is not ideal.
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 alarms to alert users when certain operating parameters are not met.
Liquid Bottle Probe
The bottle probe measures liquid temperature, giving a more accurate reflection of wine temperature than ambient cellar air readings alone.
Protective Air Filter
The added air filter helps protect the cooling unit from debris that may be present during startup, installation, or wine rack construction.
E-Coated Duramax Evaporator Coils
E-coated Duramax evaporator coils are designed to support long-term cooling performance and durability in wine cellar environments.
