Oenoflow™ XL-S Crossflow Microfiltration System

The Smart Choice for Wine Clarification

The Oenoflow XL-S systems are specifically designed to meet the needs and requirements of mid size wineries. Clarification is achieved in a single process step without the need for filter aids, centrifugation or significant impact on the organoleptic characteristics of the wine. By increasing yields, reducing waste volumes and maintaining more consistent filtrate quality, the fully automated systems provide a cost saving sustainable alternative to traditional wine clarification methods.

The systems utilize Pall’s proven hollow fiber membranes with unique mechanical strength and excellent chemical resistance which allow high productivity and repeated exposure to aggressive cleaning regimes. The large surface area modules enable manufacture of compact systems with low water and chemical consumption in line with winery conservation programs.

With adjustable operating cycles, Pall’s proprietary Low Concentration Volume (LCV) option, and automatic chemical dosing, the Oenoflow XL-S system is the smart solution for reliable and economical wine clarification. Additionally the small batch program provides the flexibility required by most modern wine cellars, packagers and mobile bottlers.

Benefits

The Oenoflow XL-S systems incorporate unique features which enable wineries to perform clarification at low operating costs while maintaining wine quality. These include:
  • PVDF membranes with high mechanical strength for longer service life
  • High area, high flow modules for more compact and more economical systems
  • Back pulse capability for increased system productivity
  • Transparent module housings to confirm filtrate quality and enhance troubleshooting capabilities
  • Fully automated working cycles for unattended operation and reduced labor and downtime
  • On board concentration and filtrate tanks for operation independent of winery conditions
  • Proprietary LCV option for high wine yield
  • Small batch program isolating 1 module for efficient processing of batches up to 1000 L
  • Water “solo” back flushes for highly effective solids removal
  • Automated chemical dosing for safe and easy cleaning
