Wine Guardian SP50 Pro Ducted Split Wine Cellar Cooling System
Sentinel Series Cooling Unit for 650–3,000 Cu. Ft. Wine Cellars
The Wine Guardian SP50 Pro is a ducted split wine cellar cooling system designed for wine rooms between approximately 650 and 3,000 cubic feet. The system separates the evaporator and condenser, allowing the compressor to be installed outside the cellar for quiet, vibration-free cooling.
Part of the Wine Guardian Sentinel Pro Series, the SP50 Pro provides stable wine storage temperatures between 52°F and 70°F (11°C–21°C) with optional humidity control to protect cork integrity and preserve wine quality. The fully ducted design keeps mechanical equipment hidden, making the system ideal for luxury residential wine cellars, restaurants, tasting rooms, and commercial wine storage environments.
With durable composite construction, service-friendly access panels, and 24-volt control compatibility for smart home and building automation systems, the SP50 Pro delivers reliable climate control for long-term wine preservation.
The SP50 Pro is a mid-capacity ducted split wine cooling system ideal for residential and commercial cellars requiring quiet, efficient climate control with a remotely located condenser. For smaller spaces, the SP25 Pro offers the same reliability in a compact form. For larger or more demanding installations, consider the SP88 Pro or SP200 Pro for extended capacity and performance.
Key Features
Quiet Split-System Operation
The SP50 Pro uses a split system design consisting of an evaporator inside the cellar and a remotely located condensing unit. By moving the compressor outside the wine room, the system reduces noise and vibration inside the cellar.
Fully Ducted Installation
Air is delivered through insulated ductwork, allowing the cooling equipment to remain hidden from view while maintaining even temperature distribution throughout the cellar.
Precise Wine Storage Temperature Control
The system maintains stable temperatures between 52°F and 70°F, the ideal range for both short-term storage and long-term wine aging.
Optional Humidity Control
Wine cellars typically require 55–65% relative humidity to prevent corks from drying out. The SP50 Pro supports integrated or freestanding humidifiers to maintain optimal humidity levels.
Smart Control Integration
The cooling system supports 24-volt thermostat controls, making it compatible with many home automation and building management systems.
Durable Construction
Wine Guardian systems are engineered with:
- Aluminum chassis construction
- UL-rated composite panels
- Powder-coated corrosion-resistant components
- Coated evaporator and condenser coils
This durable construction ensures long-term reliability in wine cellar environments.
Service-Friendly Design
Maintenance and installation are simplified through:
- Accessible service panels
- Refrigerant service ports
- Sight glass for inspection
- Removable condensate drip pad
Ideal Applications
The Wine Guardian SP50 Pro is commonly used for:
- Residential wine cellars
- Luxury glass wine walls
- Restaurant wine storage rooms
- Wine tasting rooms
- Private wine collections
- Commercial wine storage facilities
Because it is a fully ducted system, it is especially useful when equipment must remain hidden for architectural or aesthetic reasons.

📚 Frequently Asked Questions (FAQs)
The Wine Guardian SP50 Pro is designed for wine cellars between approximately 650 and 3,000 cubic feet. The exact capacity depends on insulation quality, glass surfaces, and heat load conditions.
Yes. The SP50 Pro is a fully ducted cooling system. It distributes cooled air through supply and return ducts rather than blowing directly into the cellar.
Yes. The condensing unit can often be installed outdoors or in a mechanical room, depending on the installation design and manufacturer recommendations.
Yes. Wine Guardian systems require installation by a qualified HVAC-R technician. Improper installation may reduce performance and void the manufacturer warranty.
The system primarily controls temperature but can support optional humidification systems to maintain cellar humidity between 55–65% RH, which helps preserve cork integrity.
Yes, but glass wine walls typically require careful heat load calculations and insulation design. In some cases, a larger cooling unit may be necessary depending on the amount of glass and ambient conditions."]
