What Is a Fully Ducted Self-Contained System?
A fully ducted self-contained wine cellar cooling system contains both the evaporator and condenser in one factory-sealed unit, typically located outside the wine room — in an attic, mechanical space, or nearby closet. It connects to the cellar via supply and return air ducts, creating a seamless flow of temperature- and humidity-controlled air.
Unlike split system wine cooling units, no refrigerant lines are needed — simplifying installation. And unlike through-the-wall wine cooling systems, these units are completely hidden.
Systems like the Wine Guardian D050 and CellarPro 4200VSi offer quiet, reliable, and aesthetically clean solutions for virtually any space.
Fully Ducted vs. Split vs. Through-the-Wall Cooling Units

|---|---|---|---|
| Installation | Moderate (ducts, drain) | High (refrigerant lines) | Easy (plug-and-play) |
| Noise Level | Ultra-quiet in cellar | Quiet (evaporator inside) | Louder inside cellar |
| Visibility | None (fully hidden) | Minimal (grille only) | Fully visible unit |
| Maintenance | Moderate | Higher (requires HVAC tech) | Low |
| Best For | Luxury/residential/commercial | Custom high-end cellars | Budget builds, small rooms |
