The Oenoflow™ PRO XL system is a crossflow microfiltration system designed for wine clarification in mid-sized and large wineries. It clarifies wine in a single process step without the need for filter aids or centrifugation, while helping wineries maintain consistent filtrate quality before downstream stabilization and bottling.
Built with Pall’s hollow fiber membrane technology and Oenoflow PRO Optimizer algorithm, the system combines clarification, automation and process visibility in one platform. It is designed to help wineries improve operational control while supporting reductions in water and energy use based on prior experiences.
Oenoflow™ PRO XL crossflow filtration system used for wine clarification
Why choose the Oenoflow PRO XL system?
Wine clarification needs to support filtrate quality, operating efficiency and production consistency. The Oenoflow PRO XL system is designed specifically for wineries that need a clarification system capable of handling larger production requirements in a single automated step.
Key advantages include:
- Clarification in a single process step
- No filter aids or centrifugation required
- Limited impact on the organoleptic characteristics of the wine
- More consistent filtrate quality
- A system design suited to mid-sized and large wineries

Wineries looking for a crossflow filtration system often need more than clarification alone. They also need a system that fits operating conditions, supports cleaning regimes and provides visibility across production. That is where the Oenoflow PRO XL platform is positioned.
How does the system support wine clarification?
The Oenoflow PRO XL system uses Pall’s hollow fiber membranes to separate suspended solids during wine clarification. These membranes are described as having unique mechanical strength and excellent chemical resistance, allowing high productivity and repeated exposure to aggressive cleaning regimes.
The large surface area modules also support compact system design with low water and chemical consumption. This helps wineries align clarification performance with broader conservation goals while maintaining production capability.
Core system characteristics include:
- Hollow fiber membrane technology
- High productivity under winery operating conditions
- Repeated exposure to aggressive cleaning regimes
- Compact system design
- Low water and chemical consumption
What does the Oenoflow PRO Optimizer do?
The Oenoflow PRO XL system introduces Pall’s Optimizer algorithm, which automatically adjusts system settings in real time based on the wine’s individual physical and chemical characteristics. This allows the system to replace standard settings that may not be efficient for every production cycle.
Rather than requiring operators to manage every filtration variable manually, the system is designed to simplify operation. At the start of filtration, the user only needs to enter limited batch information, while the Optimizer manages filtration-related settings.
The Optimizer algorithm:
- Adjusts filtration-related settings automatically
- Responds to the wine’s physical and chemical characteristics
- Learns and adjusts settings across production cycles
- Can be enabled or disabled by the user at any time
- Continues to support operation if the remote connection is interrupted
This level of automation also helps reduce variability between operators and supports more consistent system use across the winery.
How does the system support daily operation?
The Oenoflow PRO XL platform combines the clarification system with connected digital tools that support monitoring, reporting and service access. For wineries managing multiple users and production responsibilities, this helps bring operational data and system access into one environment.
Mobile app access
iOS and Android Oenoflow PRO apps are available for connection to the customer’s Oenoflow PRO system. These apps support live data views for real-time visualization of production data and remote diagnosis, along with push notifications for alarms and status updates.
Mobile app functions include:
- Live production data view
- Alarm and status notifications
- Site-specific access control through multiple user levels
- Access to manuals, spare parts lists and service contacts
- Service event history entry

Browser-based dashboard
The browser-based dashboard supports desktop access to operational and reporting information. It brings together production status, operating expense summaries, batch history and document storage in a format suited to winery-wide oversight.
Dashboard functions include:
- Real-time visualization of production data
- Operating expense summaries by machine and site
- Batch history for traceability
- Document storage for items such as audit reports and SOPs
- Site-specific access control through multiple user levels
Updated HMI
The updated HMI is designed to simplify operation and provide consistency with the Oenoflow PRO app and dashboard appearance. This supports a more unified user experience across the system and its connected interfaces.
What information can different winery teams access?
Different winery roles need different levels of visibility. The Oenoflow PRO XL system is designed to support that by making operational and service information accessible through the dashboard, app and system interface.
By role, the system supports:
- Executives and managers tracking water and energy use for each system, each winery or the entire winery group
- Production supervisors accessing filtration history and downloading reports for each machine, including rinse verification recorded by the included conductivity meter
- Operators viewing live production status, volume remaining to be filtered and alarms through mobile or desktop access
- Maintenance personnel accessing manuals, spare parts lists, service records and requesting service visits from Pall technicians
- Pall technicians beginning remote diagnosis once notified of system issues, which may in some cases avoid the need for an on-site visit
This combination of monitoring and access helps wineries connect day-to-day operation with performance visibility and service support.
How does the system support operating efficiency?
For wineries evaluating clarification systems, operating efficiency is often part of the decision alongside clarification performance. The Oenoflow PRO XL system is positioned to support both. Pall states that wineries using the new Oenoflow PRO XL system can realize savings in all OPEX categories when compared to traditional Oenoflow systems.
The page also states that data shows significant reductions in both energy and water use of up to 60% compared to traditional Oenoflow systems. Pall notes that these reductions are based on prior experiences and should not be used to predict future performance.
Efficiency-related benefits highlighted on the current page include:
- Reduced energy usage
- Reduced water usage
- Savings across OPEX categories compared to traditional Oenoflow systems
- Compact system design with low water and chemical consumption
