Wine Guardian D088 Ducted Wine Cellar Cooling Unit

Wine Guardian D088 Ducted Wine Cellar Cooling Unit

The Wine Guardian D088 Ducted Wine Cellar Cooling Unit is a premium, self‑contained climate control system engineered to maintain optimal temperature and humidity conditions for medium to large residential and commercial wine cellars. Part of Wine Guardian’s Sentinel Series, this ducted system houses the compressor, evaporator, fans, condenser, and controls in one unit that is installed outside the cellar, delivering conditioned air through insulated ductwork to keep the wine room consistently cool and quiet. Its broad cooling capacity (approximately 5,000–9,600 BTU/H) makes it suitable for cellars with significant storage demands.

Designed for flexible installation, the D088’s ducted configuration preserves valuable cellar space and keeps mechanical components out of sight and sound, enhancing both the aesthetic and the serene atmosphere of your wine room. The system includes a remote interface controller that monitors cellar temperature and humidity and allows you to make adjustments from inside or outside the wine cellar, supporting precise environmental management.

Built with robust materials and advanced insulation, the D088 ensures efficient performance even in demanding conditions. Its rugged construction—such as an aluminum chassis and UL‑rated panels—provides long‑lasting durability, while high static‑pressure fans and well‑insulated duct collars help reduce energy loss and maintain consistent airflow throughout the cellar.

Whether used in a residential wine room, restaurant, or commercial storage space, the Wine Guardian D088 Ducted Wine Cellar Cooling Unit delivers dependable climate control with quiet operation, flexible installation, and precise performance to help protect and preserve your wine collection.

Sentinel Series Ducted Cooling Systems

Protect your wine investment. Wine Guardian’s Sentinel Series units are the strongest and most energy efficient wine cellar cooling systems on the market. They provide optimal temperature and humidity control for both commercial and residential cellars with a design that allows for easy installation and service. Ducted systems are self-contained units that contain the evaporator, fans, compressor, condenser, and controls. This means that installation is entirely indoors. These units can be placed outside the cellar, so the system can cool the space while remaining unseen and unheard.

The Sentinel Series ducted cooling systems have a broad range of capacities at wine cellar conditions (55-58°F/12-14°C). An optional humidifier can be installed with the ability to achieve 55-65% relative humidity.

Versatile and self-contained. Wine Guardian ducted wine cellar cooling systems have been engineered for maximum flexibility in design and installation. Advanced wine cellar cooling technology creates optimal environmental conditions for any sized wine collection in any sized space — whether that is a residential, a restaurant, or commercial wine cellar.

With ducted wine cellar conditioning systems, a grille on the inside cellar wall is connected by insulated flexible ductwork to the self-contained unit outside the wine cellar. These complete systems house the evaporator, fans, compressor, condenser, and controls in just a single unit.

OUT OF SIGHT, OUT OF MIND
Relish in the quietness of your wine room with no obtrusive equipment taking up valuable wine racking space. Ducted wine cellar cooling systems are designed to be installed in a space outside the wine cellar, keeping your wine cool and your cellar quiet, beautiful, and efficient.

INSTALLATION WITHOUT THE HASSLE
We’ve made ducted wine cellar cooling units easy for contractors to install. Just connect the ductwork, make the drain connection, and plug it in. That’s it. No cutting copper and no licensed contractor needed on site.

Need to install the system against a wall or ceiling? No problem. Multiple duct configurations can be made without having to remove the fan motor or any other internal component.

A SILENT GUARDIAN
Like knights of the olden days, Wine Guardian watches over your wine room’s conditions 24/7. Equipped with air sensing technology, Wine Guardian’s modern remote interface controller constantly monitors the temperature and humidity of your cellar. If conditions leave the optimal range, the system will take action and steer the cellar back to ideal temperatures – before your wine collection is affected. 

FULL CONTROL IN ANY ROOM
The ducted system’s remote interface controller allows you to control temperature and measure humidity. With Wine Guardian-designed Wireless2Base™ technology, the controller can be placed inside the cellar, a kitchen, den or wherever is most convenient for you. An additional controller and remote sensors can be remotely connected for accurate measurements when the controller is placed outside the cellar. 

IT'S NOT JUST THE TEMPERATURE. IT'S THE HUMIDITY.
Crucial yet almost always overlooked, proper cellar humidification ensures you can enjoy 100% of the flavors of your wine. Mold, loss of liquid, and dried out corks are just some of the ways improper humidity can degrade wine quality. Wine Guardian humidifiers attach directly to your ducted system and introduce humidity back into your cellar. 

SERVICEABILITY SIMPLIFIED
With easy access quarter-turn fasteners, we’ve made self-contained wine cellar cooling units simple for servicepersons to get into the ducted unit, make repairs, and move onto the next job. And unlike our competitors, all Wine Guardian units are fully serviceable in field without needing to be returned to factory.
