Wine Guardian SP25 Pro Ducted Split Wine Cellar Cooling System
Sentinel Series Cooling for Small to Mid-Sized Wine Cellars
The Wine Guardian SP25 Pro Ducted Split Wine Cellar Cooling System is designed for wine cellars between approximately 250 and 2,000 cubic feet that require quiet, hidden cooling and flexible installation.
Unlike self-contained wine cellar cooling units, the SP25 Pro uses a split-system configuration that separates the evaporator (fan coil) and condensing unit. This allows the condenser to be installed remotely—often outside the home or in a mechanical room—while cooled air is delivered into the cellar through insulated ductwork.
This configuration significantly reduces noise inside the cellar, improves airflow flexibility, and allows cooling equipment to remain hidden, which is especially important in custom wine rooms and luxury residential cellars.
The SP25 Pro is part of the Wine Guardian Sentinel Series, engineered for reliable wine preservation, precise climate control, and long-term storage stability.
For larger applications, explore other models in the Split Pro Series — including the SP50 Pro for mid-size rooms, the SP88 Pro for broader coverage, or the SP200 Pro for maximum capacity and advanced cooling performance.
What the SP25 Pro Is Designed For
The SP25 Pro is best suited for installations where quiet performance, hidden equipment, and flexible installation are priorities.
Typical applications include:
Custom residential wine cellars
Luxury wine rooms integrated into home designs
Restaurant and hospitality wine storage
Small commercial wine storage rooms
Boutique wine retail displays
Because the system is fully ducted, no cooling equipment is visible inside the cellar, preserving the visual design of finished wine rooms.
How a Ducted Split Wine Cooling System Works
The SP25 Pro operates using a two-component split refrigeration system.
Evaporator (Fan Coil)
The evaporator is installed outside the wine cellar and distributes cooled air into the room through ductwork. It removes heat from the cellar air while circulating conditioned air back into the space.
Condensing Unit
The condensing unit is installed remotely, often outdoors or in a mechanical room. It releases heat removed from the cellar and completes the refrigeration cycle.
Separating these components allows the system to operate quietly inside the cellar while maintaining efficient cooling performance.
Ideal Wine Cellar Size and Applications
The SP25 Pro is designed for small to mid-sized wine cellars with proper insulation and vapor barrier

Actual cooling requirements depend on:
Insulation quality
Glass surfaces
Ambient temperature around the cellar
Ceiling height
Frequency of door openings
A professional cellar heat load calculation is recommended for precise sizing.
Key Features
Split System Design
Separates the evaporator and condensing unit to allow remote condenser installation, reducing noise and improving installation flexibility.
Fully Ducted Cooling
Allows cooling equipment to remain hidden while distributing conditioned air evenly throughout the cellar.
Precision Temperature Control
Maintains wine storage temperatures between 52°F and 70°F (11°C–21°C) for proper wine aging and preservation.
Smart Control Integration
Sentinel Series systems use 24-volt control architecture, enabling compatibility with smart thermostats and building management systems.
Triple-Insulated Cabinet Construction
Reduces vibration, improves energy efficiency, and helps prevent condensation within the system housing.
Modular Service Panels
Removable panels allow technicians easy access to components for maintenance and servicing.
Durable UL-Rated Composite Housing
Corrosion-resistant construction designed for long-term reliability in cellar environments.
Optional Accessories
The SP25 Pro can be customized with several optional accessories to improve climate control and installation flexibility.
Electric Heat Option: Protects wine cellars in environments where surrounding room temperatures may drop below cellar setpoints.
Extreme Climate Protection Bundle: Protects outdoor condensing units in harsh climate conditions.
Integrated or Freestanding Humidifiers: Helps maintain 55–65% relative humidity, protecting cork integrity and preventing oxidation.
Wireless Monitoring Sensors: Allow remote monitoring of cellar conditions.
Ducting Kits and Grilles Designed to optimize airflow and simplify installation.
Extended Warranty Options: Additional coverage for long-term equipment protection.
Installation Considerations
The SP25 Pro is a ducted split system, which requires professional installation and proper cellar construction.
Typical installation requirements include:
Fully insulated cellar envelope
Vapor barrier construction
Supply and return ductwork
Condensate drainage
Dedicated electrical circuit
Refrigeration line connection between evaporator and condenser
Professional HVAC installation is recommended to ensure proper performance and longevity.
Climate Stability and Wine Preservation
Long-term wine storage requires stable temperature and humidity conditions.
The SP25 Pro helps maintain a controlled environment that protects wine from:
Temperature fluctuations
Cork drying
Oxidation
Label damage
Optional humidification systems can maintain cellar humidity between 55% and 65% relative humidity, the range recommended for proper cork preservation.

📚 Frequently Asked Questions (FAQs)
The SP25 Pro is designed for wine cellars between 250 and 2,000 cubic feet, depending on insulation quality, glass surfaces, and ambient room temperatures.
Yes. The SP25 Pro is a fully ducted split cooling system and requires supply and return ductwork to circulate conditioned air into the wine cellar.
Yes. The condensing unit can typically be installed outdoors or in a mechanical room, provided the installation follows manufacturer guidelines and climate considerations.
The cooling system indirectly stabilizes humidity levels. For precise humidity control, optional humidifiers can be added to maintain 55–65% relative humidity.
Yes. Because the SP25 Pro is a split refrigeration system with ductwork and refrigerant lines, professional HVAC installation is recommended.
Most wine collections are stored between 55°F and 58°F, which helps slow aging while protecting wine from temperature fluctuations.
Because the condenser is installed remotely and the evaporator is ducted, the SP25 Pro operates very quietly inside the wine cellar, making it suitable for finished wine rooms and living spaces."]
