WhisperKOOL Quantum Twin SS18000 Wine Cellar Cooling System
A dual-evaporator, high-capacity ducted split system for very large cellars — two Quantum evaporators paired with remotely mounted, high-efficiency condensers for balanced, redundant cooling.
Quantum Twin SS18000 Key Features & Benefits
Dual-System Design for Very Large Cellars
The Quantum Twin SS18000 pairs two Quantum evaporators (18,000-class combined capacity) to condition very large cellars with even temperature distribution — ideal for expansive rooms, tall ceilings, or multi-zone layouts.
Advanced 220V High-Efficiency Condensers
The 220V high-efficiency condensers hold a 55°F cellar even in demanding mechanical rooms, with an engineered ambient operating range of -20°F to 120°F.
Fully Ducted, Concealed Design
Each evaporator installs up to 25 duct feet from the cellar and is ducted in through 14" supply and return ducts, so no equipment is visible in your wine room.
Built-In Redundancy
With two independent systems, your cellar keeps cooling even if one unit needs service — valuable protection for a large, valuable collection.
Precise Digital Control
Advanced digital displays (50-ft cables) work with liquid-temperature-measuring bottle probes, so the thermostats read the true temperature of your wine rather than the air.
Technical Specifications
| Specification | Details |
|---|---|
| Max Cellar Size | Sized for very large or multi-zone cellars — WhisperKOOL rates this system by BTU rather than a fixed cu. ft. figure, so confirm sizing with a heat-load calculation before ordering |
| Cooling Capacity | Approx. 13,806 BTU/h sensible / 16,243 BTU/h total at 85°F condenser air intake (220V H.E.); up to 18,250 BTU/h total at 60°F |
| Ambient Operating Range | Engineered to perform in ambient temperatures from -20°F to 120°F (220V H.E. condensers) |
| Refrigerant | R-134a / R-513a |
| Evaporators | Two units, 29.5"L x 30.9"W x 19.8"H each · 590–710 CFM each · 120V, 15-amp circuits · 9.2 running amps each · 96 lbs each |
| Condensers – 220V Advanced H.E. | 31.18"L x 10.75"W x 23.25"H · 210–230V, 15-amp dedicated circuits · 2.0 HP · FLA 7.56 · 116 lbs (per unit) |
| Line Set (not included) | Liquid line 3/8" OD; suction line 5/8" OD under 50 ft, 3/4" OD over 50 ft |
| Duct Size | 14" supply & 14" return per evaporator (up to 25 ft each) |
| Drain Line | 3/4" female to base (CPVC/PVC) |
| Installation Distances | Each evaporator up to 25 duct ft from the cellar; each condenser up to 100 line ft from its evaporator |
| Thermostat | Advanced digital displays (50-ft cables) with liquid-temperature-measuring bottle probes |
| Sound Level | Condensers approx. 48 dBA (220V H.E.) |
| Condenser | 220V Advanced H.E. (specs above) |
Where It Fits in the Range
The Quantum Twin SS18000 combines two Quantum evaporators for very large cellars. For the highest capacity, the Quantum Twin SS24000 pairs two 12000-class systems. Single-evaporator options include the Quantum SS9000 and SS12000. Because every large cellar is unique, always confirm sizing with a heat-load calculation before ordering.
A Note on Sizing
The cellar-size rating assumes a fully insulated room with a complete vapor barrier. Design factors such as glass walls, stone or concrete, high ambient temperatures, frequent door openings, or in-cellar lighting can increase the cooling load. When in doubt, choose the next capacity up — an undersized unit can run continuously, fail to reach temperature, and is not covered under warranty. We're happy to help you run the numbers.
Installation & Setup
Professional installation required: WhisperKOOL split systems must be installed by a qualified, licensed HVAC/R technician. Installation by anyone else will void the warranty.
Pre-Installation Requirements
- Fully insulated cellar with a complete vapor barrier
- Evaporators: dedicated 120V, 15-amp circuits
- Condensers: dedicated 220V, 15-amp circuits
- 14" supply / 14" return duct runs planned for each evaporator (up to 25 ft each)
- Line sets sized per run length (not included)
Placement & Distances
- Each evaporator ducted up to 25 duct ft from the cellar
- Each condenser up to 100 line ft from its evaporator
- Condensers can sit in a mechanical room, basement, garage, or rooftop
- Provide clear airflow around each condenser
- Route 3/4" drain lines from the evaporator bases
Cellar Design Best Practices
- Maintain consistent insulation and seal all air leaks
- Install a properly weatherstripped cellar door
- Complete the vapor barrier on the warm side of the insulation
- Plan duct routing for even coverage of a very large room
Maintenance
- Keep condenser coils clean and clear of debris
- Check the digital controllers and bottle probes periodically
- Inspect the drain lines for free flow
- Schedule an annual professional inspection
