The Wine Guardian 99H0173-20 is an integrated humidifier for wine cellar use that bolts to the side of a Sentinel Series D025, DP25, DS025 or SP25 cooling system, draws 24 Volt from that system and adds 0.42 to 1.0 lb/hr of moisture into the airstream rather than into the room.
A cooling unit is not a humidifier. Wine Guardian states that a cooling unit alone cannot add moisture or humidity to cellar air, so a controller that reads out relative humidity reports the condition without correcting it. This humidifier is the part that corrects it, and it is worth buying only if the cellar actually measures dry.
Because the moisture is introduced at the cooling system, Wine Guardian gives the integrated humidifiers a suggested maximum of 60 percent relative humidity and recommends a standalone humidifier inside the wine cellar for targets above that. As an authorized Wine Guardian dealer we sell it with Wine Guardian's own documentation and warranty; compatibility, plumbing and the electrical connection should be confirmed with a licensed HVAC professional or qualified contractor.
Wine Guardian considers 50 to 70 percent relative humidity adequate for a cellar, with 60 percent ideal. Under that range corks dry and wine oxidizes; over it labels and mold become the problem.
See where a Wine Guardian humidifier sits relative to the cooling system before you decide whether your cellar needs one at all.
Measure before you buy. Wine Guardian considers relative humidity between 50 and 70 percent adequate with 60 percent ideal, and many cellars, particularly below grade and in humid climates, already hold 50 to 70 percent without any help. Adding a humidifier to a cellar already inside that band buys a water line, a drain line and a maintenance interval for no gain. The readings and the conditions that decide it are set out in a guide to when a cellar needs a humidifier and when it does not.
What a cooling unit can and cannot do sets the test. Wine Guardian states that a cooling unit alone cannot add moisture or humidity to cellar air, so a D025, DP25, DS025 or SP25 that displays relative humidity is telling you the reading, not changing it. Log the cellar through the driest, coldest weeks of the year, when indoor air is at its driest, and buy a humidifier only if the low readings fall under 50 percent. Dry winter air, a tightly sealed vapour barrier, a fully finished room with no exposed masonry and an arid region are the conditions that usually push a cellar under the range.
Room size is decided on the cooling side, not here: Wine Guardian publishes no cellar-volume rating for its humidifiers. The four systems this humidifier mounts to are Wine Guardian Sentinel Series systems, split between the ducted configuration and the ducted split configuration, and all four sit in the band of cooling units for cellars of 1,200 to 2,200 cubic feet. A licensed HVAC professional should confirm the pairing for your room.
| Feature | What it means for your cellar |
|---|---|
| Mounts to either side | Wine Guardian states these humidification systems mount directly to either side of its self-contained ducted cooling systems or ductable split cooling units, so the installer can work with whichever side the room allows. |
| Quarter-turn fasteners | Wine Guardian describes quarter-turn fasteners that let the humidifier be removed from or attached to a Sentinel Series system in two clicks, which is what makes drip-pad service practical on a unit in an adjacent room. |
| 24 Volt from the system | Wine Guardian states the integrated humidifier is powered directly from the Wine Guardian unit with no separate power source required, so no receptacle is needed at the cooling system. |
| Moisture into the airstream | Wine Guardian describes integrated humidifiers as adding moisture to the air at the cooling unit instead of directly in the cellar, which keeps equipment and water connections out of the wine space. |
| Evaporative drip pad | Water saturates a drip pad and clean moisture evaporates into the airstream. The cover is removable and the pad is cleanable in the field. |
| Insulated against sweating | Wine Guardian describes an insulated design built from commercial-grade, lightweight materials to help prevent sweating even in humid environments. |
| Controlled from the cellar | Wine Guardian's humidifier datasheet lists a cellar-mounted remote interface controller as the control for its humidifiers, so the setpoint is read where the wine is, not where the equipment is. |
A wetted evaporative pad sits in the humidifier housing on the side of the cooling system, and the system's own airflow carries the moisture into the supply air on its way to the cellar. Wine Guardian describes this as adding moisture to the air at the wine cellar conditioning unit instead of directly in the wine cellar.
That placement is the whole trade-off. Nothing is visible inside the cellar, nothing takes rack space and no water line runs into the wine space. In exchange, the humidity the room can reach is limited: Wine Guardian gives the integrated humidifiers a suggested maximum of 60 percent RH, and recommends a standalone humidifier located inside the wine cellar to go above it. Which target to aim for, and what equipment reaches each band, is covered in a guide to cellar humidity ranges, equipment and running costs.
The practical constraints are at the equipment, not the cellar. The cooling system needs enough clearance on one side to carry the humidifier, and Wine Guardian requires the mounting location to leave access for the water supply line, the drain line, the power cord and service.

Choose the 99H0173-20 when the Sentinel Series system in the room is a D025, DP25, DS025 or SP25. Choose the 99H0173-30 when it is a D050, D088, D200 or one of the matching DP, DS and SP models; the two are rated the same and differ in the system they mount to. Choose a freestanding humidifier when the cellar is on a through-the-wall or ductless split unit, when there is no Wine Guardian unit at all, or when the target sits above 60 percent RH. Confirm the match with a licensed HVAC professional or qualified contractor.
