DUCTLESS SPLIT · Wine Wall
CS050 Wine Wall Wine Cellar Cooling Unit
The CS050 Wine Wall is a Wine Wall ductless split cooling system, rated at 4,300 BTU/h and built to hold a wine room at 55°F to 58°F. It requires no ductwork.
The CS050 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, and the paintable black grille blends into the decor of the space.
Every system ships with a coated evaporator coil, a Wireless2Base remote interface controller, aluminum chassis with corrosion-resistant, commercial-grade components, and Wine Guardian fail-safe protection. With the optional serving-temperature control the system can cool as low as 45°F, and an optional humidifier reaches 55% to 65% relative humidity. As an authorized Wine Guardian dealer, we list the CS050WW with full manufacturer specifications; installation requires a qualified contractor and final sizing should be confirmed with the Wine Guardian cooling calculator.

Is the CS050 Wine Wall Right for Your Cellar?
✓ Ideal For
- Wine walls and glass-front displays needing a slim grille flush with the ceiling
- Spaces where equipment must stay completely hidden and the grille paints to match decor
- Small to mid-sized wine displays with limited space and no ductwork
✕ Consider Another Model If
- You need the unit recessed into a ceiling between joists (use the Ceiling-Mounted model)
- You need more capacity than the Wine Wall line provides (move to a ducted split)
Key Features
| 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 cellars 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 black grille | The powder-coated grille paints to match the decor of the wine wall. |
| 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. |
| Precision control (±1°F / ±10% RH) | Holds 55°F to 58°F, with optional serving-temperature control down to 45°F and an optional humidifier for 55% to 65% relative humidity. |
| Low-ambient protection | Standard low-ambient protection keeps the system running in cold conditions; optional Xtreme low-ambient protects down to negative temperatures. |
| 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. |
Built-in protection: remote air sensing checks conditions continuously and adjusts before temperature or humidity drift can affect the collection.
How Quiet Is It
Why a Ductless Split Keeps the Cellar Quiet
Wine Guardian does not publish a single decibel rating for ductless split systems. The quiet comes from the split architecture: the noisy condenser installs separately, even outdoors, while only the fan-coil sits flush in the wine-wall ceiling, so no compressor runs inside the wine room.
- The condenser installs away from the cellar, removing its noise from the space.
- The fan-coil is a low-noise air handler with no compressor inside.
- No ductwork means no duct-borne mechanical noise to manage.

Frequently Asked Questions
CS050 Wine Wall Ductless Split FAQs
How much cooling capacity does the CS050 Wine Wall provide?
The CS050 Wine Wall is rated at 4,300 BTU/h. Net capacity changes with ambient temperature; the full table is in the specifications above. Because cellar sizing depends on insulation, glass, and use, confirm final sizing with the Wine Guardian cooling calculator and a qualified contractor.
What is a ductless split system?
A ductless split separates the evaporator (fan-coil) and the condenser into two units connected by refrigerant lines, with no ductwork at all. It is ideal for small cellars, displays, and wine walls where ducts cannot be run and space is limited.
Where does the CS050 Wine Wall install?
The CS050 Wine Wall mounts flush with the wine wall ceiling. Its slim grille sits level with the surface so no equipment is visible, and integral slot diffusers send conditioned air down the wall.
Does the CS050 Wine Wall need a licensed contractor to install?
Yes. A ductless split connects refrigerant lines between the fan-coil and condenser, so it must be installed by a licensed HVAC contractor. This also keeps the manufacturer warranty valid.
Is the CS050 Wine Wall covered by a warranty?
Yes. Wine Guardian provides a standard warranty of 2 years parts, 1 year labor (standard), with a Platinum option that Platinum option extends parts and labor to 2 years plus a 3-year extension on the compressor and coils. Warranty service is handled through the manufacturer.
