The Wine Guardian DP88WC water-cooled ducted unit is a 208-230 V, 60 Hz self-contained cabinet with R-134a refrigerant, an integral water-cooled condenser and a rated capacity of 5,000 to 9,600 BTU/h at 80°F ambient. Where a row below routes you elsewhere, it is because Wine Guardian publishes no figure against the DP88WC code, not because the figure is unimportant.
ModelDP88WC (Pro ducted, water-cooled)
ConfigurationSelf-contained and fully ductable, with an integral factory-configured water-cooled condensing coil and water-regulating valve
SeriesWine Guardian Pro ducted tier
Line frequency60 Hz
Rated cooling capacity5,000 to 9,600 BTU/h. Wine Guardian states that cooling capacity is rated at 80°F ambient, which is an ambient condition and not an entering-water temperature
Recommended space volume850 to 4,500 ft³
Conditioning temperature range (Pro ducted line)52°F to 70°F, from the Wine Guardian Ducted Pro product brochure, which describes the Pro ducted line as ideal for low-temperature air conditioning across that range
Humidity, with optional humidifier55% to 65% RH
Temperature and humidity control toleranceNot published for the Pro ducted line. The Pro ducted specifications sheet carries no tolerance row; see Wine Guardian
Heat rejectionTo a water loop, through an integral water-cooled condensing coil. Wine Guardian states that warm condenser air connections are not required
Applicable water sourcesGeothermal, cooling tower and lake water applications, requiring a year-round source of water
City water supplyWine Guardian’s Pro ducted manual states that it 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 that 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 Pro ducted specifications sheet prints its water-cooled condenser block as two unlabelled columns with no model heading over either, and the block has no third column of any kind; take these three figures from Wine Guardian and have the installing contractor confirm the loop
RefrigerantR-134a
Electrical208-230/1/60, single phase. Wine Guardian’s own DP88WC page prints this as 208-130/1/60, which is a typographical error on that page
Running current draw, coolingNot published against the DP88WC code. The Pro ducted specifications sheet carries its cooling-mode current row only under air-cooled columns; read that sheet and have a licensed electrician size the circuit
Running current draw, heatingNot reproduced here. The sheet prints the same heating-mode pair under the DP88 and the DP200 groups, a repeat that does not transcribe reliably; 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 whose pair inverts on this model; 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 DP88WC code, and the sheet’s electric-heat cell repeats across two model groups; see the Wine Guardian specifications sheet
Electric heat activationWine Guardian’s DP88WC 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 Pro ducted specifications sheet prints byte-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 DP88WC 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 DP88; 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 and ordered on Wine Guardian’s own DP88WC page. The Dimensional Data for 60Hz Models table in the Wine Guardian Pro ducted installation manual labels the same cabinet in the opposite order, as width 41.5 in, depth 22.4 in and height 18.85 in, on the Chassis B row that covers DP50, DP88 and DP200. The Pro ducted specifications sheet is not the source for this row: its physical block carries only two value columns, headed DP25 and DP50, and no DP88 column of any kind
Weight125 lbs, from the Dimensional Data for 60Hz Models table in the Wine Guardian Pro ducted installation manual, whose model-number header reads DP25 then DP50 / DP88 / DP200 and whose weight row reads 80 then 125 / 125 / 206
Condensate drain connection0.50 in inside diameter, gravity drain, with the built-in internal trap the Pro ducted manual describes
Minimum ductwork, evaporator side10 in round, from the Ductwork Diameters table in the Wine Guardian Pro ducted installation manual, whose row is labelled DP50/DP88 and gives 10 in on the evaporator side. The Pro ducted specifications sheet is not the source for this row: its physical block carries only two value columns, headed DP25 and DP50, and no DP88 column of any kind
Ductwork, condenser sideNot applicable. Heat leaves through the water loop rather than a condenser air stream, and Wine Guardian states that warm condenser air connections are not required
