WhisperKOOL Ceiling Mount Twin 9000 Ductless Split System 220V High Efficiency

Ceiling-Mounted Dual-Evaporator Cooling for Sealed Wine Cellars Up to 3,000 Cu. Ft.

The WhisperKOOL Ceiling Mount Twin 9000 (220V High Efficiency) is designed for fully insulated and vapor-sealed wine cellars up to approximately 3,000 cubic feet. This ductless split system features dual evaporators for improved air distribution and balanced cooling in larger wine rooms.

It is best suited for residential and light commercial cellars where:

• Wall space must remain available for racking
• A discreet ceiling installation is preferred
• The condenser must be located remotely
• Consistent 55°F storage conditions are required

Professional HVAC-R installation is required.

Is the Twin 9000 the Right Choice for Your Cellar?

Recommended For

• Sealed wine cellars up to ~3,000 cu. ft.
• Projects with proper insulation and vapor barrier
• Ceiling-mounted airflow preference
• Cellars with minimal wall space for mechanical units
• Condenser placement up to 100 line feet away

Not Recommended For

• Unsealed or partially insulated rooms
• High-glass cellars without load calculation
• Passive cooling attempts
• DIY installation
• Condenser locations exceeding safe ambient temperatures

If your cellar contains extensive glass, stone, or non-insulated materials, a professional heat load calculation should be performed before selecting this unit.

Why Choose a Dual-Evaporator Ceiling System?

The Twin 9000 differs from standard ceiling models by using two evaporators. This improves:

• Air circulation across larger spaces
• Temperature balance from front to back
• Cooling consistency in elongated rooms
• Performance in moderately complex layouts

The ductless design eliminates supply and return duct runs while keeping the mechanical components visually unobtrusive.

Cooling Performance Specifications

All performance data assumes a fully insulated cellar with proper vapor barrier.

Cooling Capacity – Twin 9000

What These Ratings Mean

Cooling capacity decreases as condenser intake temperature rises. If the condenser is installed in:

• Direct sun
• Attics
• Garages in hot climates
• Poorly ventilated spaces

System output will decline. Shaded, ventilated condenser placement is strongly recommended.

Temperature Capability

The Twin 9000 is engineered to maintain a 55°F cellar temperature with condenser air intake temperatures up to 120°F, assuming proper installation conditions.

Operating beyond recommended environmental limits may reduce performance and system lifespan.

Noise Levels

• Evaporator: 48 dBA (Medium) / 53 dBA (High)
• Condenser: 43 dBA

This makes it suitable for luxury residential installations where acoustic control is important.

Physical Specifications

• Evaporator Dimensions: 35.75” L x 14.5” W x 12.75” H
• Condenser Dimensions: 31.18” L x 10.75” W x 21.18” H
• Weight: 66 lbs (Evaporator) / 64 lbs (Condenser)

Electrical Requirements

• Evaporator: 120V (15 amp dedicated circuit required)
• Condenser: 220V (15 amp dedicated circuit required)
• Refrigerant: R-134a
• Maximum line set length: 100 ft
• Drain line: 1/2” ID clear plastic tubing (not included)

Improper electrical setup may void warranty.

Installation Requirements

• HVAC-R professional installation required
• Fully sealed vapor barrier required
• Insulation must meet wine cellar standards
• Evaporator mounts flush between ceiling joists
• Condenser must have adequate ventilation

Failure to properly insulate or seal the cellar can result in:

• Continuous operation
• Inability to maintain temperature
• Premature system wear

Controls & Monitoring

Advanced Digital Display

• 50 ft communication cable
• System protection alerts
