Eaton Offers the Perfect Combination of Filter Cartridges for Pre-Filtration and Final Filtration of Wine and Sparkling Wine

Date: 8/01/2017

LANGENLONSHEIM, GERMANY … The Filtration Division of power management company Eaton provides innovative filtration solutions for the global food and beverage industry. Eaton recently expanded its range of BECO® pre- and membrane filter cartridgesBECO PROTECT FS FineStream™ pre-filter cartridge and the new BECO MEMBRAN PS Wine™ membrane filter cartridge offer the perfect combination of pre-filtration and final filtration for full-bodied, bright and stable wines and sparkling wines.


For wine filtration, a two-stage pre-filtration system effectively protects downstream membranes. In the first stage, a pre-filter from the BECO PROTECT FS range with a retention rating (ß ratio ≥ 5000) of 1 or 2 µm is used as a particle filter. In the second stage, a fine filter from the same range with a retention rating of 0.3 or 0.5 µm helps ensure optimal preparation of the wine for the next step, membrane filtration, by reducing the colloids, proteins and tannins that can result in premature membrane blockage. For sterile filtration before bottling, the BECO MEMBRAN PS Wine membrane filter cartridge, which can be tested for integrity and has an absolute retention rating of 0.45 or 0.65 µm, can be used as a downstream “police filter” to reduce or remove yeast and bacteria.


The innovative and unique special pleating of the fine polypropylene fleece in the 
BECO PROTECT FS FineStream pre-filter cartridge provides outstanding results; increasing the filter area in the filter cartridge while keeping the pressure difference at a low level. The service life of the pre-filter cartridge is significantly longer than wrapped standard filter cartridges. In addition, it also supports variable flow, as the wrapping and its drainage follows the principle of an hourglass and therefore functions in both directions; so in different process configurations the direction of flow can be from the outside in or, especially in the filtration of very expensive products, from the inside out. As a result product loss is reduced to a minimum when draining the housing. The looped pleating around the inner core ensures the individual loops hold each other in place and maximize mechanical stability. This special design also helps prevent deformation of the pleating during backwashing at up to 2 bar and 80 degrees Celsius.


The BECO MEMBRAN PS Wine membrane filter cartridge, which is specifically designed for wine filtration, is optimally tailored to the requirements and long service life of final filtration. The filter material consists of pleated polyethersulfone and, with an LRV (Log Reduction Value) greater than 7 per cm², provides high microbiological retention. The membrane’s asymmetrical pore size distribution ensures valuable components such as long-chain fatty acid esters, anthocyanins and fine colloids are preserved almost in their entirety. The special structure also helps preserve the rich and brilliant color of red wines and the particular typicity of maturing white wine. With 0.78 m² per 10-inch element, the filter area is designed for high flow rates and an excellent long service life. The fully welded design with additional polypropylene support fleece increases mechanical stability, withstands a differential pressure of 5 bar in and 2 bar against the direction of flow at 20 degrees Celsius, as well as more than 100 steam cycles.
