WhisperKOOL SC PRO 3000 Wine Cellar Cooling Unit

Through-the-Wall Wine Cellar Cooling Unit for Rooms up to 650 Cu. Ft.

The WhisperKOOL SC PRO 3000 is a self-contained, through-the-wall wine cellar cooling system designed for properly insulated and sealed wine rooms up to 650 cubic feet.

It is intended for interior installations where the condenser intake air temperature does not exceed 85°F.

When installed in a correctly constructed wine cellar with proper vapor barrier and heat load calculation, the SC PRO 3000 can maintain a stable 55°F storage environment for long-term wine preservation.

Available in WhisperKOOL SC PRO 2000 for 300 cu.ft. wine cellar, WhisperKOOL SC PRO 4000 for 1000 cu.ft. wine cellar, and WhisperKOOL SC PRO 8000 for 1500 cu.ft wine cellar.

Quick Decision Summary

The SC PRO 3000 is appropriate if:

• Your cellar is ≤ 650 cubic feet
• The room is fully insulated
• A vapor barrier is installed
• Condenser intake air remains ≤ 85°F
• You want a non-split, self-contained system

It is not appropriate if:

• Intake air exceeds 85°F
• The room lacks insulation or vapor barrier
• The space exceeds 650 cu. ft. after heat load calculation
• You need long duct runs or remote condenser placement

How the SC PRO 3000 Works

Centrifugal Blower System

Advanced blower fans replace traditional axial fans to produce stronger, more uniform airflow. This reduces temperature stratification and improves consistency across the cellar.

TXV (Thermostatic Expansion Valve)

The system uses a smart metering TXV valve to regulate refrigerant flow dynamically. This improves efficiency and stabilizes cooling performance under varying load conditions.

Liquid-Temperature Bottle Probe

Unlike systems that measure only air temperature, the SC PRO 3000 measures the temperature of the wine itself. This allows for more accurate long-term storage control.

Integrated Condensate Evaporator

The unit can evaporate up to approximately 3 ounces of condensate per hour under standard conditions. A drain line is still recommended in humid climates as a secondary precaution.

Digital Controller with System Protection

The front-facing digital interface includes operational alerts to notify users if temperature or performance deviates from normal parameters.

Coated Evaporator Coil

The protective coil coating enhances corrosion resistance and supports long-term reliability.

Installation Requirements (Critical for Performance)

To achieve rated performance:

• Room must be fully insulated
• A proper vapor barrier must be installed
• A dedicated 115V / 20-amp circuit is required
• Condenser intake temperature must remain at or below 85°F
• Heat load calculation should be completed before purchase

Failure to meet these conditions may result in reduced cooling capacity or short cycling.

Installation Type: Through-the-wall (partially ducted optional)

For exterior installations or high ambient temperatures, consider WhisperKOOL Extreme Series systems.
