The Wine Guardian DP50 is a self-contained, air-cooled Pro-series ducted wine cellar cooling unit that delivers 6,320 BTU/h at 80°F condenser inlet air, measured with the cellar held at 57°F and 55% relative humidity, and holds the wine room anywhere in the 52°F to 70°F storage range Wine Guardian publishes for the Ducted Pro line.
Wine Guardian publishes the DP50 at 2,700 to 6,320 BTU/h and sizes it for residential and commercial wine cellars of roughly 650 to 3,000 cubic feet. Volume alone does not size a cellar, though: glass area, the R-values and insulation materials the walls carry, door traffic and the temperature of the space the unit exhausts into all change the load, so run your own cellar dimensions and R-values through the wine cellar cooling calculator before you settle on a model.
Because the unit installs outside the wine room and connects through insulated ductwork, the cellar stays quiet and uncluttered, with every inch of space free for storage. The Pro platform adds high- and low-pressure switches, a refrigerant sight glass, 24-volt electronics and operation in cold ambient conditions that the standard ducted line does not carry. A feature-by-feature account of the Pro tier against the standard Sentinel ducted units covers where that package is worth specifying. As an authorized Wine Guardian dealer, we publish the DP50 with full manufacturer specifications so you can compare and size it correctly, and you can request a price quote with your cellar dimensions if you want a configuration checked before ordering.

The DP50 is the right unit for a wine cellar of roughly 650 to 3,000 cubic feet that has somewhere outside the room to hold a single chassis and exhaust its heat, with insulated supply and return ducts running into the cellar. Below that range the capacity is more than the room needs; above it, the DP88 is the correct starting point.
The DP50's defining features are its single-chassis self-contained design, the Pro platform's high- and low-pressure switches and refrigerant sight glass, and precision control to ±1°F and ±10% RH through the Wireless2Base remote interface controller.
| Feature | What it means for your cellar |
|---|---|
| Self-contained ducted design | All components (evaporator, fans, compressor, condenser, controls) sit in one unit outside the cellar, so the wine room stays quiet and clutter-free. |
| Air-cooled heat rejection cooling | Vents heat to a separate space outside the cellar, keeping the wine room cool, quiet, and undisturbed. |
| Pro high- and low-pressure switches | Shut the system down before a refrigerant pressure problem damages the compressor if the system is undercharged, overcharged or leaking. |
| Refrigerant sight glass | Shows the refrigerant volume at a glance, so a technician can diagnose a charge problem without gauges on the first visit. |
| Cold-ambient operation | Wine Guardian rates the ducted Pro units for operation below 40°F ambient, so an unheated garage or basement is a workable location. |
| 24-volt electronics | The Pro control platform runs on 24-volt electronics, which is what allows the system to tie into Wi-Fi and smart-home integration. |
| Coated evaporator coil | Protects the evaporator side against corrosion for durable, reliable performance over long service life. |
| Wireless2Base remote interface controller | Monitors temperature and humidity continuously and corrects conditions before your wine is affected; place the controller in a kitchen, den, or elsewhere. |
| Precision control (±1°F / ±10% RH) | Holds the setpoint to within ±1°F anywhere in the 52°F to 70°F storage range Wine Guardian publishes for the Ducted Pro line, with an optional humidifier for 55% to 65% relative humidity. |
| Aluminum chassis with UL-rated composite panels | UL-rated composite panels are roughly five times stronger than before and resist dents and scratches during shipping and installation. |
| Field-serviceable, multi-panel access | Panels, duct collars, and grille remove with a couple of screwdriver turns, so service happens on-site without returning the unit to the factory. |
| No refrigerant line work on site | The sealed refrigerant circuit stays inside the single chassis, so installation is ductwork, a drain connection and power rather than field-brazed copper. |
| Optional bundles and humidification | All Wine Temperatures, Extreme Climate Protection, and Ultimate bundles add heating, low/high ambient protection, and serving-temperature control as your space requires. |
Built-in protection: the system continuously checks conditions through remote air sensing and adjusts before temperature or humidity drift can affect the collection.
Wine Guardian publishes no decibel rating for its ducted units, and the honest reason is that placement, not the unit, decides what you hear: the DP50 installs outside the wine room and connects through insulated ductwork, so the compressor and fans are never in the space you occupy. What reaches the cellar is air movement through a duct, not machinery.
How much of that advantage you actually get comes down to the layout, which is why planning duct runs and unit placement is worth settling before the equipment is ordered. Wine Guardian recommends a maximum cumulative length of 25 feet for the supply and return ducts combined, including bends. Anyone comparing quoted decibel figures between brands should treat an unqualified number with caution unless the measurement distance is stated with it.
The Wine Guardian DP50 specifications below are the manufacturer's published figures for the 60 Hz unit, including the full net-cooling ladder by condenser inlet air temperature, measured with the cellar held at 57°F and 55% relative humidity. Capacity falls as the air entering the condenser gets warmer, so read the row that matches the space the unit will exhaust into rather than a single headline number.
On the electrical rows: the minimum circuit ampacity and electric-heat figures printed for the Pro models are inconsistent across the model columns of the current Ducted Pro specifications sheet, so this page does not publish them. Take those two values from the manufacturer's sheet and have a licensed electrician confirm the branch circuit for your installation.
Accessory availability and pricing are confirmed on each live product page. An integrated or freestanding Wine Guardian humidifier can be added to reach 55% to 65% relative humidity.
The DP50 is the middle of the Pro ducted line: choose it for cellars of 650 to 3,000 cubic feet, step down to the DP25 for smaller rooms, and step up to the DP88 for cellars of up to 4,500 cubic feet. The three units differ on cellar volume, capacity, compressor size and the electrical supply they need, not on the quality of the cooling.
| Decision factor | DP25 Pro ducted | DP50 Pro ducted | DP88 Pro ducted |
|---|---|---|---|
| Recommended cellar volume | 250–2,000 ft³ | 650–3,000 ft³ | 850–4,500 ft³ |
| Cooling capacity at 80°F condenser inlet air | 3,760 BTU/h | 6,320 BTU/h | 9,420 BTU/h |
| Nominal compressor | 0.33 HP | 0.50 HP | 1.0 HP |
| Electrical supply | 115 V, single phase, 60 Hz | 115 V, single phase, 60 Hz | 208 V or 230 V, single phase, 60 Hz |
Best for / not ideal for: choose the DP50 if the cellar is between about 650 and 3,000 cubic feet and a standard 115 V circuit is what you have to work with. Choose the DP25 for smaller rooms of 250 to 2,000 cubic feet if you would otherwise be oversizing. Choose the DP88 for cellars up to 4,500 cubic feet, accepting that it needs a 208 V or 230 V supply rather than 115 V. The DP50 is part of the Wine Guardian Pro series of ducted, water-cooled and split cooling systems; if you are shopping by room size instead of by installation type, compare it against the other cooling units for cellars of 2,200 to 4,500 cubic feet.
