Wine cellars require highly reliable climate-control units to mimic natural cave-like conditions, ensuring stable temperature and humidity for the preservation and ageing of wine. For larger spaces or situations where noise and heat need to be separated from the living area, split-system machines like the Fondis Winemaster SP40 and SP80 Dupro are the perfect solution.
Produced in France by the renowned company Fondis, these machines are trusted worldwide for their precision, performance, and long lifespans. The SP40/80 Dupro models
in particular are highly valued because they provide professional grade climate control while allowing the compressor and condenser to be installed away from the cellar, keeping the storage environment quiet and unobtrusive.
SP40 vs SP80 Dupro: Which Model Is Right for Your Wine Cellar?
Choosing between the Fondis Winemaster SP40 and SP80 Dupro depends primarily on your cellar size and cooling demands. The SP40 is typically ideal for medium-sized wine cellars (around 20–40 m³), making it perfect for private collectors or compact commercial spaces. The SP80, on the other hand, is designed for larger wine rooms (up to approximately 80 m³), often found in restaurants, wine bars, or serious collector installations.
Both models offer precise temperature control (14°C–18°C), stable humidity regulation, and split-system quiet operation. However, the SP80 provides greater cooling capacity and airflow, making it better suited for cellars with higher heat loads, glass walls, or frequent access. Consulting a wine cellar specialist ensures the correct sizing based on insulation, room design, and bottle capacity, preventing underperformance or unnecessary energy use.
Why Choose a Split-System Wine Cellar Cooling Unit Over a Self-Contained System?
- Ultra-Quiet Operation– The compressor and condenser are installed away from the cellar, eliminating internal noise and vibration that could disturb your wine or living space.
- Reduced Vibration– Minimal mechanical vibration helps protect wine from long-term molecular disturbance during ageing.
- Better Heat Management– Heat is expelled externally through the outdoor condenser, preventing warm air buildup around the cellar.
- Improved Energy Efficiency– By separating components, the system operates more efficiently, especially in larger installations.
- Ideal for Medium to Large Cellars– Perfect for custom wine rooms, restaurants, and commercial spaces requiring consistent climate control.
- Greater Installation Flexibility– Indoor and outdoor units can be positioned strategically to suit design and structural needs.
- Long-Term Reliability– Split systems like the SP40/80 Dupro offer professional-grade performance and durability for serious collectors.
Here are seven reasons why the Fondis Winemaster SP40/80 Dupro is such a popular choice:
1. Professional Temperature Control in All Seasons
The SP40/80 Dupro maintains the perfect cellar climate year round, keeping wine at an ideal range between 14°C to 18°C. Equipped with advanced electronic regulation, the system constantly monitors conditions and adjusts cooling output automatically. Whether summer heat or winter cold, your wine is always stored under optimal conditions.
2. Humidity Regulation
Like all Fondis units, the SP40/80 Dupro doesn’t just manage temperature – it also stabilises humidity. Maintaining a range of 50%–80% humidity prevents corks from drying
out and wine from oxidising, while also avoiding excessive dampness that could damage labels or wooden racks.
3. Split-System Design = Quiet Operation
One of the biggest advantages of the Dupro range is its split-system design. The compressor and condenser can be located outside the cellar or even outside the building,
meaning no intrusive noise or vibration inside your wine space. This creates a true sanctuary where your collection ages naturally, unaffected by the hum of machinery.
4. Energy Efficiency
The SP40/80 Dupro models are engineered for efficiency, consuming minimal electricity while running continuously. They are designed with eco conscious operation in mind,
offering long term energy savings without compromising cellar performance.
5. Flexible Installation Options
The Fondis Winemaster SP40/80 Dupro is perfect for larger cellars, from 20 m³ to 80 m³. Its split-system design lets the indoor evaporator be placed discreetly above or beside the cellar, up to 6 meters away with ducting, while the outdoor condenser can be positioned up to 20 meters away.
This flexibility makes it ideal for custom wine rooms in homes, restaurants, or commercial spaces, ensuring quiet, efficient climate control without compromising cellar layout or aesthetics.
6. Filtration and Reliability
The condenser unit incorporates a protective filtration system, ensuring dust and particles do not interfere with it. This extends the machine’s durability and keeps performance at a consistently high level.
7. Built to Last
Made in the Alsace region of France, these machines use premium European components sourced from France, Germany, and Italy. With a typical lifespan of 10+ years and many
units running reliably far beyond that, the SP40/80 Dupro is a long term investment in the preservation of your wine collection.
Final Notes
The Fondis Winemaster SP40/80 Dupro is widely regarded as one of the best split system cooling solutions for medium to large wine cellars. Its quiet operation, flexible installation, precise climate control, and long service life make it ideal for both private collectors and professional venues such as wine bars, restaurants, or boutique wineries.
