WhisperKOOL manufactures specialized wine cellar cooling systems designed to meet a wide range of installation needs—from simple residential builds to fully customized luxury cellars. The product lineup is organized into four primary product families, each engineered for specific applications, performance requirements, and installation environments.
Understanding these categories makes it easier to select the ideal solution for your cellar’s size, layout, and design goals.
Wine is highly sensitive to temperature fluctuations. Cooling systems are designed to counteract the heat entering the cellar and maintain stable storage conditions. This incoming heat—known as the heat load—is measured in BTUs per hour (BTU/h) and determines the capacity your cooling unit must deliver.
A properly sized system ensures:

Self-contained systems combine the evaporator and condenser into a single housing, making them one of the most straightforward cooling solutions available.
SC Series
Slimline Series
Non-ducted Extreme ti / tiR units
These units are typically mounted through a wall, with the evaporator inside the cellar and the condenser exhausting into an adjacent space such as a utility room.
Simple installation that does not require a licensed HVAC technician
Compact, all-in-one design
Reliable cooling performance for properly built cellars
Proper construction is essential for performance:
Minimum insulation of R-13 (R-19 recommended for interior walls; R-30 for ceilings/exterior walls)
Fully sealed vapor barrier to prevent moisture transfer
Adequate ventilation clearance—about three feet minimum (five feet ideal) to dissipate exhaust heat
Best For: Straightforward installations, retrofits, and projects needing fast deployment.
The Fully-Ducted Self-Contained category includes ducted versions of Extreme tiR units and Phantom systems.
Unlike standard self-contained units, these systems are installed in a remote location—such as an attic—with cooled air delivered into the cellar through ducting.
Keeps equipment out of the cellar to maximize storage space
Offers flexible placement options for cleaner design integration
Typically operates more quietly than in-cellar systems
Recommended duct runs within ~25 feet (up to 50 feet maximum).
Best For: Homeowners or designers who want hidden mechanical equipment without moving to a split system.
Ductless split systems separate the evaporator and condenser into two components connected by a line set.
Ceiling Mount Series
Platinum Mini Split
Platinum Split and Twin configurations
Evaporator installs inside the cellar for powerful, direct cooling
Condensing unit can be placed remotely (attic, outdoors, mechanical room) to reduce noise
Ideal when there’s no suitable space to vent a self-contained unit.
Because of their technical complexity, split systems must be installed by a qualified HVAC professional.
Best For: High-performance cooling with quieter operation and flexible condenser placement.
Fully ducted split systems—including ducted Platinum Split models and the Quantum Series—allow both the evaporator and condenser to be located outside the cellar.
Conditioned air is delivered through ducting rather than from a visible in-cellar unit
Both system components can be installed remotely for a completely hidden design
Line sets can extend up to 100 feet, allowing exceptional installation flexibility.
Preserves wall space for racking and aesthetics
Minimizes equipment visibility and noise
Enables highly customized cellar layouts
Best For: Luxury builds, large custom cellars, and projects prioritizing invisibility and architectural freedom.
Selecting the right cooling system depends on three primary considerations:
Simplest: Self-contained
Moderate: Fully ducted self-contained
Advanced: Split systems (HVAC installation required)
Want visible, direct cooling → Self-contained
Want equipment hidden → Ducted or split systems
Smaller residential cellars → Self-contained
Larger or high-end installations → Split or ducted split systems
Each product family is engineered to match a specific cellar design strategy and application requirement.
A: Self-contained units house all components together, while split systems separate them for quieter operation and more flexible installation.
A: Self-contained systems are generally easier to install, but split systems require professional HVAC installation due to their complexity.
A: Ducted systems allow equipment to be installed remotely, preserving cellar space, reducing noise, and creating a clean, design-focused aesthetic.
A: Insulation, vapor barriers, and ventilation are essential to ensure cooling units operate efficiently and protect the wine collection.
