PREXA N-SMART
PNEUMATIC NITROGEN PRESS N-SMART
The PREXA N-SMART is one of the most innovative oenological presses on the market and is distinguished by its state-of-the-art technology. This oenological equipment is ideal for anyone looking for a nitrogen pressing method to improve the quality of the must extracted.
The SMART system, designed by Puleo S.p.A., introduces a new perspective on pressing with inert gas. It utilises the pressurised nitrogen in the tank, supplied by external systems, to ensure continuous draining of the must. Winemakers who adopt it achieve a better yield and higher quality of the final product. This system is more effective than any other type of pressing.
An important advantage is the slight pressure generated inside the closed tank of the pneumatic press. This pressure allows the must to be extracted quickly and sent immediately to the storage tanks. Thus, the durantion of the stay of the must inside the press is reduced. This preserves the freshness of the wine product and increases the efficiency of the winemaking process.
Technical features
The PREXA N SMART is a hybrid pneumatic press that can be used in two modes:
- SMART mode: provides for the inflow of disposable nitrogen, allowing nitrogen-saturated pressing, which improves the quality of the must.
- Standard mode: works like the PREXA C, a classic closed-tank pneumatic press, with must extraction through draining channels. The opening of the nozzles allows the product to flow out to an external collection basin.
Advantages
- high yield of qualitative and quantitative extraction of must due to continuous pressurisation of the inert gas;
- radical reduction of the must stay in the press: the must is quickly extracted and separated from the marc.
Key

- “User friendly” user interface with color touch screen display.
- Sequential “crémant” pressing program with pre-loaded recipe according to French oenological techniques.
- 14 fully customizable pressing programs.
- Dual automatic (PLC) / manual control system.
- On-board rubber impeller must pump.
- Fully automated recirculating washing system.
- Automatic marc discharge.
- Inerting primary must collection tank.
Options
- Remote control panel on pedestal.
- Elevations for press base.
- Large/double pneumatic door.
- Two-way must selection with pneumatic valves.
- Refrigeration band.
- Remote assistance.
- Polyurethane membrane.
Innovative
Details
Significantly reduced inerting and pressing times
The pressurized nitrogen that enters the press chamber for each cycle promotes continuous and increased draining compared to classical pressing systems, with excellent yield/quality results of the extracted product.
Radical reduction of must residence time inside the press.
The must is immediately extracted and separated from the marc.
Fully automated recirculation washing system
Automatic washing system by recirculating water allows complete and accurate washing of the draining channels and all points in contact with the must. At the start of washing, the Press will automatically ration the required amount of water while the on-board pump will start recirculating water throughout the circuit for a the time set at the start of the phase. At the end of the process there is a discharge phase for the wastewater produced.
UNLIMITED availability of nitrogen
Up to 99.9% new and pure nitrogen always available and without the need for recirculation and storage systems.
Crémant Pressing Program.
Sequential “Crémant” pressing program with preloaded recipe according to current regulations.
Membrane coupling system.
Allows rapid assembly and disassembly without additional stress, extending the life of the membrane.
