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

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

The WhisperKOOL Ceiling Mount Twin 9000 220V High Efficiency Ductless Split System is a premium cooling solution designed for properly insulated and vapor‑sealed wine cellars up to approximately 3,000 cubic feet. Its dual evaporator design mounts flush with the ceiling, keeping the cooling mechanism out of sight while efficiently drawing warm air from the ceiling and distributing cooled air evenly throughout the space to help maintain ideal wine storage conditions.

This 220V high‑efficiency split system offers improved energy performance and quieter operation compared to standard voltage models, making it a great choice for residential and light commercial wine rooms where noise reduction and performance matter. Its flexibility allows the condenser to be positioned remotely up to 100 feet away from the evaporators, minimizing noise and maximizing usable cellar space.

Designed with professional installation in mind, the system includes upgraded features such as easy‑access bottom wiring, line set access, and flare fittings to simplify setup and service. The KDT digital touch display and liquid bottle temperature probe deliver precise temperature monitoring and control, ensuring your wine collection is stored accurately and consistently.

Whether you’re building a bespoke residential wine room or outfitting a commercial display, the WhisperKOOL Ceiling Mount Twin 9000 delivers dependable performance with discreet installation and advanced control capabilities.

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
• Environmental monitoring

Liquid Bottle Probe

• Measures liquid temperature rather than ambient air for more accurate wine preservation.

Optional 24V Thermostat Conversion Kit

• Compatible with customer-supplied smart thermostats
• Enables Wi-Fi monitoring and alerts

WhisperKOOL does not provide or support third-party thermostat troubleshooting.
