The Advanced Solution for Large WineriesThe Oenoflow XL-A systems are specifically designed to meet the needs and requirements of large wineries and bottlers. 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 system utilizes 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 customizable operating cycles, process trend recording and a wide range of options, the Oenoflow XL-A system offers an advanced solution with the flexibility required in most modern wine cellars, custom crush and bottling operations.
BenefitsThe Oenoflow XL-A systems incorporate unique features which enable wineries to perform clarification at low operating costs while maintaining wine quality.
