CellarCool Through-The-Wall Wine Cooling Units

CellarCool through-the-wall wine cooling units are designed for sealed residential wine cellars that require a simple, self-contained cooling solution with direct exhaust into an adjacent space. These systems are best suited for small to mid-sized cellars where ducting is not possible and installation efficiency is a priority.

Is a Through-the-Wall Cooling Unit Right for Your Cellar?

Through-the-wall systems are built for controlled environments where the cellar shares a wall with a ventilated room. They provide reliable cooling when used within their design limits and installed in properly constructed spaces.

• Best for cellars typically under 1,000 cu. ft.
• Requires a nearby room to exhaust heat
• Works only in sealed, insulated environments
• Designed for straightforward wall-mounted installation

If your cellar falls outside this range, choose a system based on capacity:

• Cooling units for under 500 cu. ft.
• Cooling units for 500–999 cu. ft.
• Cooling units for 1000–1999 cu. ft.
• Cooling units for 2000+ cu. ft.

Key Installation Requirements

Through-the-wall systems depend on proper construction and environmental conditions. Failure to meet these requirements will result in poor performance or system failure.

• Insulation: Minimum R-13 wall insulation and R-19 ceiling insulation required
• Vapor Barrier: Mandatory to prevent moisture migration and condensation issues
• Ventilation: Exhaust room must dissipate heat continuously
• Ambient Conditions: Exhaust space must stay within manufacturer temperature limits
• Wall Access: Direct penetration through the cellar wall is required

Technical Specifications & Performance

CellarCool through-the-wall systems are engineered for consistent operation within controlled residential environments. Performance depends on proper sizing and installation.

• Cooling capacity designed for small to mid-sized cellars
• Temperature range: typically maintains 55°F–58°F
• Humidity support for proper wine storage conditions
• Self-contained system with integrated evaporator and condenser
• No external condenser or ductwork required
• Low to moderate noise levels depending on installation

How Through-the-Wall Systems Work

These systems are installed directly into the cellar wall. The evaporator pulls warm air from the cellar, cools it, and recirculates it back into the space. The condenser expels heat into the adjacent room, eliminating the need for remote components. Explore the full CellarCool product range to compare configurations.

When NOT to Use a Through-the-Wall Cooling Unit

• Do not use in cellars exceeding the unit’s rated capacity
• Do not install in uninsulated or poorly sealed environments
• Do not exhaust into enclosed or non-ventilated rooms
• Do not use in glass-heavy or high heat-load cellars

If your project falls into these conditions, consider alternative systems:

• Ductless split systems – for higher heat loads and flexible installation
• Ducted split systems – for larger cellars and hidden installations
• Self-contained ducted units – for controlled exhaust placement
