Fan-Coil Options
Condenser Options

Options:

*Heater

Protects wine cellars from dangerously low temperatures. Adjustable activation from 2 - 6°F (-17 - -14°C) below your setpoint.

**Extreme Climate Protection Bundle

For Self-Contained Ducted systems: Contains an integral compressor crankcase heater and controls to protect the system against low temperatures (required when inlet air to the condenser coil is below 40°F/5°C). The bundle also contains an integral high capacity condenser fan and coil for operation at elevated ambient temperatures. This bundle should be considered when inlet air to the condenser coil is above 100°F/38°C (condenser air inlet cannot exceed 120°F/49°C).

For Ducted Split systems: Unit protection in extreme climate conditions (on the condenser section only). It is required for continuous operation in climates that fall below 20°F. Enables the system to operate in temperatures as low as -20°F.

Wine Guardian Sentinel Series

Wine Guardian SP88 Pro Ducted Split Wine Cellar Cooling System

The Wine Guardian SP88 Pro is a professional-grade ducted split wine cellar cooling system designed for large residential wine cellars, luxury wine rooms, hospitality venues, restaurants, and specialty storage applications requiring quiet operation, remote equipment placement, and precise climate control.

As part of the Wine Guardian Sentinel Series, the SP88 Pro separates the fan coil and condensing unit so conditioned air can be delivered through ductwork while heat-producing mechanical equipment remains outside the wine storage environment.

Important: Do not size this system by cubic footage alone. Insulation, vapor barrier quality, glass exposure, ambient temperature, ceiling height, duct design, and total heat load all affect cooling performance.

Overview of the Wine Guardian SP88 Pro

The Wine Guardian SP88 Pro is built for large wine cellar projects that need professional-grade cooling performance, flexible installation, and reduced in-cellar noise. Unlike general air conditioning equipment, this wine cellar cooling system is designed around the temperature and humidity requirements of long-term wine preservation.

The ducted split design allows the fan coil and condensing unit to be installed separately. This helps keep operating noise and heat rejection away from the wine storage area while allowing conditioned air to be delivered through ductwork.

Will the SP88 Pro Fit Your Wine Cellar?

The SP88 Pro is rated for wine cellars from approximately 850 to 4,500 cubic feet. Actual system performance depends on cellar construction, insulation quality, vapor barrier installation, door sealing, ceiling height, glass exposure, duct configuration, ambient temperature, and internal heat sources.

For large wine rooms, restaurant cellars, and commercial storage applications, a professional heat-load calculation should be completed before selecting the SP88 Pro. A cellar with heavy glass exposure, poor insulation, or high surrounding temperatures may require more cooling capacity than cubic footage alone suggests.

Important Sizing Note: An undersized cooling system can run continuously, fail to maintain target temperature, and shorten equipment life. Always verify cellar load requirements before ordering.

Key Features and Benefits

Ducted Split Configuration

The fan coil and condensing unit install separately, allowing the system to deliver conditioned air through ductwork while keeping mechanical noise and heat away from the wine cellar.

Precision Wine Storage

The SP88 Pro supports a 52°F–70°F operating range for wine storage environments that require stable climate control.

Optional Humidity

Optional integrated or freestanding humidifiers can help support proper relative humidity levels.

Smart Controls

24V electronics support building management systems, home automation integration, and compatible modern smart thermostats.

Modular Build

UL-rated composite panels, aluminum chassis construction, and corrosion-resistant materials support long-term durability and service access.

Triple-Insulated Cabinet

Triple-insulated construction helps reduce heat transfer and minimize condensation in demanding wine cellar environments.

Installation Requirements

The SP88 Pro is a professional ducted split cooling system and should be installed by qualified HVAC or refrigeration professionals familiar with wine cellar cooling applications.

  • Separate fan coil and condensing unit installation locations are required.
  • Professional refrigeration line installation is recommended.
  • Proper cellar insulation and vapor barrier construction are required.
  • Duct pathways must be planned before installation.
  • The condenser location must provide ventilation and service access.
  • Dedicated electrical service must match system requirements.
  • System sizing should be verified before purchase.

Optional Accessories

What’s Included

  • Wine Guardian SP88 Pro fan coil unit
  • Matched condensing unit
  • Interchangeable duct collars and panels

Operating in Demanding Temperature Conditions

The Wine Guardian SP88 Pro is designed for demanding wine cellar environments where stable temperature control is required. Its advanced condenser and ducted split configuration help support consistent performance when installation conditions require remote heat rejection and quiet in-cellar operation.

Extreme ambient conditions still affect system sizing and performance. Hot, cold, glass-heavy, or poorly insulated spaces should be evaluated carefully before selecting this unit.

Wine Guardian Dealer Expert Recommendation

The SP88 Pro is a strong choice for large wine cellar projects where quiet operation, remote equipment placement, and ducted installation flexibility are priorities. It is best suited for properly insulated wine cellars with verified cooling load requirements and enough space for professional split-system installation.

Choose the SP88 Pro when the cellar is too large for smaller split models but does not require the maximum capacity of the SP200 Pro.
