🔧 What Is a Ductless Split Wine Cooling System?
Unlike self-contained or ducted systems, a ductless split setup places the evaporator inside your cellar and the compressor (condenser) outside, reducing noise and vibration dramatically. A refrigerant line connects the two.

- 🧱 Preserve Design Aesthetics – Ideal for glass walls or wood racks
- 📏 Control Larger Spaces – Up to 1000 cu. ft. capacity
