For wine collectors looking for high-performance cooling without the complexity of ductwork, a ductless split wine cooling system is an ideal solution. These systems offer excellent temperature and humidity control, low noise levels, and a clean, modern aesthetic—making them perfect for small to medium-sized wine rooms.
At Wine Cooling Pro, we provide ductless split systems from the industry’s top brands, offering the perfect balance of power, flexibility, and ease of use for both residential and commercial wine cellars.
What is a Ductless Split System?
A ductless split system consists of two main components:
- The evaporator unit, installed directly inside the wine cellar, mounted on a wall or
ceiling. - The condenser unit, located in a remote space—usually outdoors or in an oversized
mechanical room.
The two components are connected by refrigerant and electrical lines, not ducts. This allows
for easier installation than ducted systems while still achieving quiet, efficient cooling.
Key Benefits
No Ductwork Required
Simplifies installation, especially in spaces where ducting is not feasible or would impact the
design.
Low Noise and Vibration
The condenser is placed remotely, significantly reducing sound and mechanical vibration in the
cellar.
Clean, Compact Design
The indoor evaporator unit is sleek and modern, with many models offering unobtrusive, slim
profiles.
Precision Climate Control
Maintains optimal wine storage conditions—typically 55°F (13°C) and 50–70% humidity with
added humidifier—with advanced digital thermostats and built-in sensors.
Flexible Installation Options
Ideal for residential or light commercial cellars where outdoor access is available but duct routing is limited.
How it Works
- The indoor evaporator unit draws in warm cellar air.
- It cools and bolsters humidity in the air using an internal coil system.
- Conditioned air is recirculated into the cellar, while the heat is transported via refrigerant
lines. - The remote condenser releases the heat outside or into a vented, oversized
mechanical space.
Because there are no ducts, this system is faster to install and requires fewer architectural modifications—yet it provides powerful performance.
Installation Considerations
Ductless split systems are easier to install than ducted options but still require proper planning and a licensed HVAC technician.
Key considerations include:
- Line Set Distance: Most systems allow up to 50–100 feet between evaporator and condenser.
- Drainage: A condensate drain line must be installed for moisture removal.
- Power Supply: Units typically require a dedicated circuit with sufficient voltage.
- Wall Strength: The evaporator must be mounted securely, often on a load-bearing wall.
- Ventilation: The condenser needs proper airflow to release heat efficiently.
We offer technical support before and during installation to ensure your system performs at its
best.
Best Use Cases
A ductless split system is ideal for:
- Small to mid-sized wine rooms (250 to 2,000 cubic feet)
- Renovated or retrofitted spaces without room for ductwork
- Wine cellars inside apartments, condos, or townhomes
- Clients who value ease of installation and quiet operation
- Cellars with limited mechanical space nearby
If you’re building a modern wine room and need quiet, efficient cooling with minimal structural changes, this is the perfect option.
