WhisperKOOL Quantum Twin 24000 Ducted Split System 220V High Efficiency

Ducted Split Cooling System for Wine Cellars Up to 7,500 Cubic Feet

The WhisperKOOL Quantum Twin 24000 is a commercial-grade, fully ducted split wine cellar cooling system engineered for large residential estates, hospitality environments, and commercial wine storage rooms up to 7,500 cubic feet when properly insulated and vapor sealed.

With a 3 HP compressor and high-efficiency 220V condenser, this system delivers up to 25,317 BTU/h (total capacity at 85°F condenser intake) while maintaining a stable 55°F cellar temperature in demanding installations.

This system is designed for projects that require high airflow, remote equipment placement, and discreet ducted operation.

• System Type: Fully ducted split system
• Max Cellar Size: 7,500 cu. ft. (proper insulation required)
• Voltage: 120V evaporator / 220V condenser
• Compressor: 3 HP
• Cooling Capacity (85°F intake): 21,519 BTU (Sensible) / 25,317 BTU (Total)
• Installation: Licensed HVAC-R technician required
• Line Set Included: No

Heat load calculations are strongly recommended before selecting this system.

Who This System Is Designed For

The Quantum Twin 24000 is appropriate when:

• Your cellar exceeds 5,500 cubic feet
• You have significant glass exposure
• You need ducted, hidden mechanical equipment
• The condenser must be installed remotely (up to 100 ft)
• The project is commercial or hospitality-grade
• The installation environment reaches up to 120°F condenser intake temperatures

This unit is commonly used in:

• Large luxury residences
• Restaurants and hospitality wine rooms
• Commercial wine storage facilities
• Estate-scale wine vaults

When This System Is NOT Appropriate

This system may not be suitable if:

• Your cellar is under 4,000 cu. ft.
• Insulation is below recommended R-values (R-19 walls / R-30 ceiling minimum typical)
• No properly installed vapor barrier is present
• You cannot supply a 220V dedicated circuit
• You need a self-contained or through-wall solution

An oversized unit in a small cellar can short cycle. An undersized unit in a large cellar will run continuously and may fail prematurely.

Cooling Performance by Ambient Temperature

Cooling capacity varies depending on condenser air intake temperature.

What this means:
As ambient temperatures increase, total output slightly decreases. Proper ventilation of the condenser location is critical for peak efficiency.

The system is capable of maintaining a 55°F cellar temperature with condenser air intake temperatures up to 120°F when installed correctly.

Fully Ducted Operation for Quiet Cellars

The Quantum Twin series is fully ducted, keeping mechanical noise and heat outside the cellar.

Duct Requirements:

• 14” Supply
• 14” Return
• Up to 35 ft per duct run

Line Set Distance:

• Condenser may be installed up to 100 ft from evaporator

Noise Levels:

• Evaporator: 58 dBA
• Condenser: 58 dBA

Ducted systems are preferred in luxury builds where equipment visibility and vibration must be minimized.

Electrical Requirements (Planning Critical)

Evaporator: 120V — 15-amp dedicated circuit required

Condenser: 220V — 25-amp dedicated circuit required

Electrical planning must be completed prior to installation. Always verify breaker sizing and wiring capacity.

Installation Requirements

• Liquid Line: 3/8”
• Suction Line: 5/8” (under 50 ft) or 3/4” (over 50 ft)
• Drain Line: 3/4” Female to base (CPVC/PVC)
• Line set not included
• Professional HVAC-R installation required

Failure to use a licensed technician will void warranty coverage.

24000 vs 18000 — When to Upgrade

Choose the 24000 if:

• Your cellar exceeds 5,500 cu. ft.
• You have higher glass exposure
• You are in a hot climate
• You want extra performance margin

Advanced Controls & Monitoring

The system includes:

• KDT digital touch display (50 ft cable)
• Liquid-temperature measuring bottle probe (50 ft cable)

The bottle probe measures actual wine temperature instead of ambient air, improving long-term aging consistency.
