Unrivaled. Efficient. Affordable.

The SC PRO Series is a self-contained, through-the-wall wine cellar cooling system engineered for properly sealed and insulated small to mid-sized wine cellars. It is purpose-built to maintain a stable 55°F wine storage environment when condenser intake air temperatures do not exceed 85°F.

Yes, but glass significantly increases heat load. In glass-heavy designs: Cellar size ratings are reduced Higher-capacity models are often required Insulation and door sealing become critical. Heat load calculations should always be performed before selection.

Yes. The SC PRO Series is a direct replacement for legacy XLT units, fitting similar wall openings while delivering quieter operation and improved efficiency.

No. The SC PRO installs through the wall and is designed to be installed without an HVAC-R technician, provided all installation guidelines are followed, including ventilation, electrical requirements, and drainage.

Yes. The SC PRO is commonly installed indoors and operates efficiently when the indoor exhaust area remains properly ventilated.

The SC PRO is designed to maintain a 55°F cellar temperature when condenser intake air does not exceed 85°F. Operation above this limit will reduce performance and may shorten system life.

The SC PRO uses a centrifugal blower system designed to deliver strong airflow with reduced noise, making it suitable for living spaces.

The SC PRO uses a liquid-temperature bottle probe to measure wine temperature directly, providing more stable and accurate control than air-only sensing.

No. The SC PRO uses an on-unit digital controller with bottle probe and does not support remote thermostats or smart home integration. Control logic is built into the unit to protect wine storage conditions.

No, exterior-wall installations are not recommended. Exposure to high ambient temperatures, weather, or poor airflow can reduce performance and shorten system life

Only if ambient temperatures remain below 85°F year-round. Garages that exceed this temperature will compromise performance and may void warranty coverage.

No. The SC PRO must remain fully exposed on the cellar side to maintain proper airflow across the evaporator face. Recessing or enclosing the unit restricts airflow and can cause icing, short cycling, and system shutdown.

Yes. A drain line is required as a backup, even though the system includes internal condensate evaporation.

Yes. When properly sized and installed, the SC PRO maintains stable conditions ideal for long-term wine storage and aging.
