WhisperKOOL SC Pro 4000: Advanced Wine Cellar Cooling System
Professional-grade cooling unit designed for mid-sized wine cellars up to 1,000 cubic feet with advanced condensate management and whisper-quiet operation technology.
SC Pro 4000 Key Features & Benefits
Advanced Blower Technology
The SC Pro 4000 utilizes a revamped centrifugal blower system that delivers significant direct, robust airflow while operating at exceptionally quiet levels. This blower revolution ensures even distribution of conditioned air throughout your wine cellar, maintaining consistent temperatures across all storage areas.
Smart Condensate Management
Advanced condensate evaporator effectively processes up to 3 ounces of condensate per hour, rendering the traditional drain line as an additional safeguard rather than a definite requirement. This innovative system prevents moisture buildup and simplifies installation requirements.
Digital Temperature Control
Features an advanced digital controller with liquid temperature measuring bottle probe that provides accurate reflection of your wine's actual temperature. This precise monitoring system ensures optimal cellar environment and prevents temperature fluctuations that could damage your collection.
Advanced System Protection
Built-in advanced system protection with intelligent alarms alerts you when certain parameters aren't met, preventing premature failure and protecting your valuable wine investment. The system continuously monitors performance to ensure optimal operation.
Flexible Power Options
Power can be supplied from either the front or rear of the unit, providing installation flexibility. The unit plugs into your standard 115V electrical outlet, eliminating the need for specialized electrical work in most installations.
Coated Evaporator Coil
Enhanced evaporator coil coating provides superior protection against corrosion and extends system lifespan, ensuring reliable performance in various environmental conditions while maintaining efficient heat transfer.
The SC Pro 4000 combines advanced cooling technology with user-friendly operation for the ultimate wine preservation solution.

Heat Load Calculation Requirements
Proper heat load calculations are essential before selecting any cooling unit. The SC Pro 4000's 1,000 cubic foot capacity assumes a fully insulated cellar with proper vapor barrier. Variables that may require a larger unit include:
- Building Materials: Glass walls, stone, concrete with insufficient insulation
- Ambient Temperature: Locations with high ambient temperatures
- Cellar Usage: Frequent door openings or high traffic areas
- Lighting: Heat-generating lighting systems within the cellar
Installation Requirements & Considerations
Pre-Installation Requirements
- Fully insulated cellar with R-19 minimum insulation
- Complete vapor barrier on warm side of insulation
- Dedicated 20-amp electrical circuit (115V)
- Through-the-wall opening: 18" W × 15" H minimum
- Adequate ventilation on condenser side
Installation Process
- Mark and cut through-the-wall opening
- Install single-piece mounting bracket
- Position unit and secure to bracket
- Connect electrical power (front or rear option)
- Install drain line if desired (optional)
- Test operation and temperature settings
Cellar Design Best Practices
- Maintain consistent insulation thickness
- Seal all air leaks with appropriate materials
- Install door with proper weatherstripping
- Consider thermal mass for temperature stability
- Plan for adequate wine rack ventilation
Maintenance Schedule
- Monthly: Check digital controller readings
- Quarterly: Clean condenser coils
- Semi-annually: Inspect drain line and bottle probe
- Annually: Professional system inspection
- As needed: Replace air filters if applicable
Common Installation Mistakes to Avoid
- Inadequate Insulation: Using less than R-19 insulation or incomplete vapor barrier
- Poor Ventilation: Blocking condenser airflow or installing in confined spaces
- Electrical Issues: Using inadequate circuit amperage or improper grounding
- Improper Sizing: Not accounting for glass walls, ambient temperature, or usage patterns
- Drainage Problems: Improper drain line routing when condensate management isn't sufficient
Professional Installation vs. DIY
While the SC Pro 4000 is designed for straightforward installation, consider professional installation if:
- Electrical work requires permits in your area
- Structural modifications are needed for wall penetration
- Cellar insulation or vapor barrier needs improvement
- Complex ducting arrangements are required
- Local codes require licensed contractor installation

Questions, answered
WhisperKOOL self-contained FAQ
Straight answers from the team that sizes, installs and services wine cellar cooling every day.
Can I install a self-contained WhisperKOOL myself?
Yes. Self-contained through-the-wall units like the SC PRO mount between the studs of an existing wall and plug in, so they do not need a licensed HVAC/R technician. You do need a dedicated circuit and a drain line, and the room on the exhaust side has to stay ventilated.
What size unit does my cellar need?
Start with the cellar's volume (length × width × height in feet), then adjust for insulation, glass, stone and how hot the room behind the unit gets. WhisperKOOL's ratings assume a fully insulated cellar with a vapor barrier at 55°F. If your cellar is near the top of a unit's range, or has glass or stone, go one size up. Our free heat-load calculation removes the guesswork.
Where does the hot air go?
Out the back of the unit, into the room on the other side of the wall. That room should stay under 85°F and have enough space and airflow to take the heat. If it gets hotter, consider the Extreme series or a split system.
Is it loud?
The compressor and fans sit in the wall, so a self-contained unit makes some noise inside the cellar. The SC PRO's newer fan design runs quieter than older models. If you want near-silence in the cellar, look at ducted or split systems.
I'm replacing an older WhisperKOOL. Will it fit?
Many SC PRO units fit openings left by older SC and XLT models, but not every one is a direct swap. Send us your old model number and we will confirm the fit before you order.
Do I need to connect a drain line?
Yes, always. The unit produces condensate while it cools, and the drain line must be connected to protect your cellar and keep the warranty valid.
What warranty comes with it?
WhisperKOOL self-contained units carry a limited 2-year warranty plus a 5-year compressor warranty from the date of purchase. As an authorized dealer, we help you register the unit and file any claim.
