Key Features
Key Features of the Wine Guardian SP88 Pro
Ducted Split-System Design
The SP88 Pro separates the evaporator and condenser so the condensing unit can be installed remotely from the wine cellar.
This provides greater installation flexibility than a self-contained ducted system and helps move compressor heat and noise farther away from the conditioned wine room.
High-Capacity Cooling
The supplied performance table lists total cooling capacity up to 10,700 BTU/h at a 60°F condenser inlet temperature.
Precise Wine Storage Temperature Control
The supplied content identifies a temperature operating range of 52°F–70°F.
Humidity Management Compatibility
Optional integrated or freestanding humidification can support relative humidity around 55%–65%.
24-Volt Smart Control Integration
The SP88 Pro includes 24-volt control electronics that support integration with:
- Smart thermostats
- Building management systems
- Home automation systems
Modular Composite Cabinet Construction
The evaporator cabinet uses an aluminum chassis with UL-rated plastic panels.
Triple-Insulated Cabinet Design
The supplied content identifies multi-layer cabinet insulation intended to reduce heat transfer and help limit condensation within the equipment cabinet.
Service-Friendly Access
Removable access panels are designed to help qualified technicians inspect and service internal components.
Quiet Cellar Operation
Because the condenser is installed remotely and conditioned air is distributed through ductwork, the SP88 Pro is designed to reduce mechanical noise inside the wine cellar.
Buyer Fit
Who Is the Wine Guardian SP88 Pro Best For?
Large Residential Wine Cellars
The supplied product content positions the SP88 Pro for residential wine cellars within approximately 850–4,500 cubic feet when the calculated load fits its capacity.
Restaurants and Wine Bars
Commercial hospitality applications can benefit from remote condenser placement and ducted conditioned-air delivery.
Luxury Wine Display Rooms
Custom display spaces can use the SP88 Pro where the cooling equipment should remain discreet and the main condenser needs to be located away from the wine room.
Glass Wine Walls
Larger glass-heavy installations can use the SP88 Pro where the calculated cooling demand remains within the system's available capacity.
Projects Requiring Quiet Equipment Installation
The split configuration helps reduce compressor noise near the wine cellar.
Custom Ducted Cellar Designs
The SP88 Pro is well suited to projects where supply and return ductwork can be incorporated into the cellar design.
When the SP88 Pro Is Not the Right Choice
- Do not select the SP88 Pro for small wine cabinets or very small closets where a simpler system is more appropriate.
- Do not use it where suitable duct routing cannot be provided.
- Do not proceed without professional HVAC support.
- Do not use it for temporary wine-storage installations.
- Do not select it solely from cubic footage without calculating the heat load.
- Consider the SP25 Pro or SP50 Pro for smaller applications.
- Consider the SP200 Pro for more demanding high-capacity applications.

Choose From the Calculated Cooling Load
Cellar volume is only a starting point. Glass area, insulation, vapor-barrier quality, lighting, ambient conditions, duct losses, and condenser conditions can materially affect the required model.
System Operation
How the SP88 Pro Ducted Split System Works
1. Warm Cellar Air Returns Through Ductwork
Warm air from the wine cellar is routed through the return-air duct to the evaporator.
2. The Evaporator Removes Heat
The evaporator coil absorbs heat from the cellar air.
3. Conditioned Air Returns to the Wine Cellar
The evaporator fan circulates cooled air back through the supply-air duct system.
4. Refrigerant Transfers Heat to the Remote Condenser
The split refrigeration circuit carries the absorbed heat away from the evaporator.
5. The Remote Condensing Unit Rejects Heat
The condenser releases heat at its remote installation location, helping keep compressor heat and mechanical noise away from the wine room.
Why Split Configuration Matters
Separating the evaporator and condensing unit allows the heat-rejection equipment to be placed farther away from the cellar than with a self-contained system.

Airflow Performance Warning
Avoid restrictive duct layouts, poorly sized ductwork, excessive bends, and blocked grilles that could reduce airflow through the evaporator.
Installation
Installation Requirements and Planning Considerations
Professional HVAC Installation Is Required
The supplied product content specifically states that wine-cellar cooling systems require professional HVAC installation.
Provide Proper Insulation
The wine cellar should be properly insulated before the cooling system is commissioned.
Install a Sealed Vapor Barrier
A sealed vapor barrier is identified as an important requirement for controlling moisture and heat infiltration.
Complete a Heat-Load Calculation
A project-specific heat-load calculation should be completed before final system selection.
Provide Adequate Duct Routing
The cellar design must provide sufficient space for supply and return ductwork.
Plan the Remote Condenser Location
The supplied content identifies mechanical rooms, attic spaces, and exterior locations as possible condenser-placement options.
Provide Condensate Drainage
The evaporator includes a 0.5-inch condensate drain connection.
Installation Warning
Improper insulation, vapor-barrier construction, airflow, condenser placement, or system installation can significantly reduce cooling performance.
