DUCTLESS SPLIT · Wine Wall

CS025 Wine Wall Cooling System for Wine Walls up to 1,200 Cubic Feet

The Wine Guardian CS025 wine wall cooling system is a ductless split wine cellar cooling unit that Wine Guardian publishes at 400 to 2,755 BTU for wine walls and glass displays of 100 to 1,200 cubic feet. Wine Guardian rates ductless split cooling capacity at 80°F ambient, and states that the maximum capacity for this system is 2,755 BTU/H.

The CS025 Wine Wall is built for wine walls and glass-front displays: its slim grille mounts completely flush with the ceiling so no bulky equipment is visible, and integral supply and return slot diffusers distribute conditioned air evenly down the wall. The condenser installs separately, in a space with enough air volume or ventilation to carry its heat away, and the paintable aluminum grille blends into the decor of the room. It holds long-term storage conditions of 55°F to 58°F, and the optional serving-temperature package extends the range the system controls to, which Wine Guardian publishes as 42°F to 64°F.

Every system ships with a coated evaporator coil, a Wireless2Base remote interface controller, an aluminum chassis with corrosion-resistant, commercial-grade components, and Wine Guardian fail-safe protection; an optional humidifier reaches 55% to 65% relative humidity. As an authorized Wine Guardian dealer we list the CS025WW with full manufacturer specifications, and it is one of the ductless split wine cooling systems in the Wine Guardian line. Installation requires a qualified contractor, and final sizing should be confirmed with the Wine Guardian sizing calculations and a licensed HVAC professional.

Fit Check

Is the CS025 Right for Your Glass Wine Wall?

The CS025 Wine Wall suits a glass wine wall or open display of 100 to 1,200 cubic feet where the cooling grille has to sit flush in the ceiling and stay visually quiet. Because glass carries far more heat than an insulated wall, a heavily glazed display reaches the top of that band at a smaller volume, and the glazing and vapor barrier have to be settled before the unit is sized. A glass display also brings condensation, UV and noise questions an insulated cellar does not, all of them set out in a breakdown of seven glass cellar problems and the fix for each.

✓ Ideal For

  • Glass wine walls and display cabinets of 100 to 1,200 cubic feet
  • Wine walls needing a slim grille flush with the ceiling and no visible equipment
  • Rooms where the grille should paint to match the surrounding decor
  • Small to mid-sized wine displays with limited space and no route for ductwork

✕ Consider Another Model If

  • The ceiling has to stay completely blank, in which case the CS025 Ceiling Mount hides the evaporator between standard joists
  • The space is larger than 1,200 cubic feet, where the CS050 Wine Wall carries 250 to 2,200 cubic feet
  • There is no location away from the display that can absorb or vent the condenser heat
  • You need built-in humidification rather than an optional freestanding humidifier
Key Features

Wine Guardian CS025 Wine Wall Key Features

The CS025 Wine Wall pairs a flush-mounted fan-coil with a separately located Wine Guardian condenser, so a wine wall gets full cellar-grade climate control without ductwork or visible equipment. The table below translates each feature into what it means for your wine wall.

Feature What it means for your cellar
Ductless split design Separate fan-coil and remote condenser install in different locations with no ductwork at all, fitting wine walls where ducts are impossible.
Slim flush-ceiling design The low-profile grille mounts completely flush with the wine wall ceiling, so no bulky equipment is visible in the display.
Integral slot diffusers Supply and return slot diffusers in the grille distribute conditioned air evenly down the wall.
Paintable aluminum grille The all-aluminum grille paints to match the decor of the wine wall and removes without tools for service.
Perfectly paired condenser The condensing unit is engineered and manufactured by Wine Guardian to work specifically with the fan-coil for reliable matched performance.
Coated evaporator coil Protects the evaporator side against corrosion for durable performance over a long service life.
Wireless2Base remote interface controller Monitors temperature and humidity continuously and corrects conditions before your wine is affected; place it outside the wine space if preferred.
400 to 2,755 BTU capacity band Wine Guardian publishes 400 to 2,755 BTU for this unit, rated at 80°F ambient, which covers wine walls of 100 to 1,200 cubic feet.
Precision control Holds 55°F to 58°F within plus or minus 1°F. The optional serving-temperature package carries a published option range of 42°F to 64°F, and an optional humidifier reaches 55% to 65% relative humidity.
Low-ambient protection Low Ambient Protection guards the system below 40°F. Xtreme low ambient protection is offered as a separate option, and Wine Guardian attaches no condenser inlet air temperature figure to it, so confirm cold-weather limits with Wine Guardian and a licensed HVAC professional.
Field-serviceable, tool-free access The grille and panels remove without tools for in-field service, so the unit does not return to the factory.
Hinged grille for one-person installation Wine Guardian's hinge design lets a single installer set and drop the grille during installation and service.

Built-in protection: remote air sensing checks conditions continuously and adjusts before temperature or humidity drift can affect the collection.

How Quiet Is It

How Quiet Is the CS025 Wine Wall Cooling System?

Wine Guardian does not publish a decibel rating for the CS025 Wine Wall, so no dB figure is claimed here. What can be stated is the architecture: the compressor sits in the remote condenser, away from the wine wall, and only a low-noise fan-coil remains in the ceiling of the display.

Why a Ductless Split Keeps the Wine Wall Quiet

The quiet comes from the split architecture rather than from sound insulation: the noisy condenser installs separately, even outdoors, while the fan-coil sits flush in the wine-wall ceiling, so no compressor runs inside the wine space.

  • The condenser installs away from the display, removing its noise from the room.
  • The fan-coil is a low-noise air handler with no compressor inside.
  • No ductwork means no duct-borne mechanical noise to manage.
  • Because Wine Guardian publishes no dB rating for this model, ask a licensed HVAC professional to assess the condenser location if the room is noise-sensitive.

Not ideal for: a room whose ceiling must stay completely blank, where the CS025 Ceiling Mount hides the evaporator between standard joists at the same 100 to 1,200 cubic feet, or a space above 1,200 cubic feet, where the CS050 Wine Wall covers 250 to 2,200 cubic feet.

Frequently Asked Questions

CS025 Wine Wall Questions

Does the CS025 Wine Wall control humidity on its own?
The CS025 Wine Wall holds temperature and monitors humidity through the Wireless2Base remote interface controller, but reaching 55% to 65% relative humidity requires the optional Wine Guardian humidifier. Control accuracy is plus or minus 1°F and plus or minus 5% relative humidity.
Will a glass wine wall get condensation once the CS025 Wine Wall is running?
Condensation on a wine wall is a glazing and vapor barrier question rather than a cooling unit question. Holding the space at 55°F to 58°F widens the temperature difference across the glass, so insulated glazing and a continuous vapor barrier are what keep the surface dry. Confirm the glazing and vapor barrier with your glass supplier and a licensed HVAC professional before the unit is sized.
Where does the CS025 Wine Wall condenser go and where does its heat end up?
The condenser is a separate unit that installs away from the wine wall and rejects its heat into whatever space it sits in. That space needs enough air volume or ventilation to carry the heat away, which is why the condenser location is settled before the fan-coil position is fixed. Confirm the condenser location and its heat rejection with a licensed HVAC professional.
Can a glass-fronted wine wall hold cellar conditions?
A glass-fronted wine wall can be held at 55°F to 58°F, but glass carries far more heat than an insulated wall, so the glazed area drives the heat load and the unit has to be sized for it. Wine Guardian publishes 100 to 1,200 cubic feet for the CS025 Wine Wall at 400 to 2,755 BTU, and a heavily glazed wall reaches the top of that band at a smaller volume. Confirm final sizing with a licensed HVAC professional.
What happens if the CS025 Wine Wall is oversized for the space?
An oversized unit satisfies its setpoint quickly and short-cycles, which pulls humidity down and adds wear to the compressor. Wine Guardian notes that many variables affect proper unit sizing, including type of construction, insulation values, amount of glass, and residential versus commercial use, so sizing should be done with the Wine Guardian sizing calculations and a licensed HVAC professional.
How much cooling capacity does the CS025 Wine Wall have?
Wine Guardian publishes a capacity of 400 to 2,755 BTU for the CS025 Wine Wall and states that the maximum capacity for this system is 2,755 BTU/H. Wine Guardian rates ductless split cooling capacity at 80°F ambient.
What size wine wall does the CS025 cool in cubic feet?
Wine Guardian publishes a volume of 100 to 1,200 cubic feet for the CS025 Wine Wall. That is a published range rather than a guarantee for a specific room, so confirm final sizing with the Wine Guardian sizing calculations and a licensed HVAC professional.
Does the CS025 Wine Wall need a licensed contractor to install?
Yes. A ductless split connects refrigerant lines between the fan-coil and the condenser, so it must be installed by a licensed HVAC contractor. Professional installation also keeps the Wine Guardian warranty valid.
Is the CS025 Wine Wall covered by a warranty?
Yes. Wine Guardian provides a standard warranty of 25 months parts and 13 months labor, and a Platinum option that extends parts and labor to 25 months with a 36-month parts-only extension on the compressor, evaporator coil and condenser coil, 61 months in total. Warranty and service run through Wine Guardian.
