The Wine Guardian DP50WC is a 115 V, 60 Hz self-contained ducted unit with R-134a refrigerant, a water-cooled condenser and a rated capacity of 2,700 to 6,320 BTU/h. Wine Guardian rates cooling capacity at 80°F ambient. Where a row below routes you elsewhere, it is because Wine Guardian publishes no figure against the DP50WC code, not because the figure is unimportant.
ModelDP50WC (Pro ducted, water-cooled)
ConfigurationSelf-contained, fully ductable, with a factory-configured integral water-cooled condensing coil and water-regulating valve
SeriesWine Guardian Pro ducted tier
Line frequency60 Hz
Rated cooling capacity2,700 to 6,320 BTU/h. Wine Guardian states cooling capacity is rated at 80°F ambient
Maximum capacity6,320 BTU/h. Wine Guardian’s own DP50WC page also prints 6,570 BTU/h in its description paragraph, in a sentence that names the DP50; the Additional Information table figure is what is published here
Recommended space volume650 to 3,000 ft³
Conditioning temperature range (Pro ducted line)52°F to 70°F
Humidity, with optional humidifier55% to 65% RH
Humidity and temperature control toleranceNot published for the Pro ducted line. See the Wine Guardian specifications sheet
Heat rejectionTo a water loop, through a factory-configured water-cooled condensing coil
Warm condenser air connectionsNot required. Wine Guardian’s DP50WC page states that warm condenser air connections are not required, which makes the water-cooled option a solution where warm condenser air venting is not possible
Applicable water sourcesGeothermal, cooling tower and lake water applications, requiring a year-round source of water
Geothermal pump controlTie-in points on the main control board, per Wine Guardian’s water-cooled ducted line page
City water supplyWine Guardian does not recommend using a water-cooled system on a city water supply
Entering water temperature, safe operating range45°F to 85°F
Above 85°F entering waterWine Guardian warns you risk tripping the high-pressure switch
Water connectionsCopper straight tube, cooling water inlet and outlet
Water regulating valveIntegral, factory configured
Water flow rate, pressure drop and connection sizeNot reproduced here. The Wine Guardian Pro ducted specifications sheet prints its water-cooled condenser block with no model headings over the columns and the code DP50WC appears nowhere in it; take these three figures from Wine Guardian and have the installing contractor confirm the loop
RefrigerantR-134a
Electrical115/1/60, single voltage
Running current draw, coolingNot published against the DP50WC code. The Pro ducted specifications sheet carries a cooling-mode current row only under its air-cooled DP25 and DP50 columns; read that sheet and have a licensed electrician size the circuit
Running current draw, heatingNot reproduced here. See the Wine Guardian specifications sheet and a licensed electrician
Minimum circuit ampacity and maximum overcurrent protectionNot reproduced here. The sheet prints these in a combined heat / no heat cell that does not transcribe reliably; read the Wine Guardian specifications sheet and have a licensed electrician size the circuit
Electric heatAvailable as a factory option. Wattage not published against the DP50WC code; see the Wine Guardian specifications sheet
Electric heat activationWine Guardian’s DP50WC page states that the heater option protects wine cellars from dangerously low temperatures, with adjustable activation from 2°F to 6°F below your setpoint
Evaporator and condenser fan motor sizeNot reproduced here. The Wine Guardian Pro ducted specifications sheet prints identical figures on both rows; take them from Wine Guardian
Nominal compressorNot reproduced here. The sheet carries this row only under its air-cooled performance blocks, with no DP50WC column
Capacity at varying condenser inlet air temperaturesNot applicable. The performance ladder on the Pro ducted specifications sheet is measured against condenser inlet air and belongs to the air-cooled DP50; a water-cooled condenser has no inlet air
Dimensions (L x W x H)41.5 in x 22.5 in x 19 in, as printed on Wine Guardian’s DP50WC page. The Pro ducted specifications sheet labels the same cabinet in the opposite order, as width 41.5 in, depth 22.4 in and height 18.85 in
Weight125 lbs
Condensate drain connection0.50 in. Wine Guardian’s Pro ducted manual gives the drain as half-inch copper tubing
Minimum ductwork size10 in. From the Pro ducted specifications sheet column carrying this cabinet’s 41.5 in length and 125 lb weight; the sheet carries no DP50WC column of its own
Low ambient protectionStandard
ControlsEnhanced refrigeration controls, 24-volt electronics, compatible with modern smart thermostats
Sound ratingWine Guardian publishes no decibel rating for its ducted units
Agency approvalApproved by ETL according to UL 1995 and CSA safety standards
InstallationWine Guardian requires installation and maintenance by qualified personnel familiar with local codes and regulations
Warranty25 months parts, 13 months labor
