From vine to bottle, protected.
Every gas and liquid contact in the cellar — from inert-gas blanketing to the bottle headspace — is a route for oxidation or spoilage. We supply the filters that close every one of those gaps.
Oxidation · Brettanomyces · re-fermentation in glass · a vintage that took a year to make.
Winemaking is a sequence of gas- and liquid-contact events from the press to the moment the cork goes in. Inert blanketing gas keeps oxygen off the wine. Every tank-vent breathing cycle is a route for airborne yeast, mould and acetic-acid bacteria. The final membrane is the last barrier against spoilage organisms, and the bottle-headspace gas is the last contact before sealing — get any one wrong and the vintage oxidises or re-ferments in glass.
Ultrafilter supplies filtration to wineries — sterile P-SRF depth elements (0.2 µm, min. 100 sterilisation cycles) for inert blanketing and bottle-headspace gas, P-BE vent filter elements and PF-PT PTFE membrane elements for tank venting, PF-BEV double-layer PES final membranes for the wine itself, and P-GS VE sintered-stainless steam filters for SIP/CIP. FDA 21 CFR per product DoC; EC 1935/2004 for P-SRF elements. Every element ships with its datasheet and food-contact Declaration of Conformity; sterile elements also with integrity-test record and validation guide.
Every filtration duty in your plant is covered by one of these product families. Each ships with its datasheet and food-contact Declaration of Conformity; sterile elements also with a validation guide.
In-line sterile CO₂ / N₂ for inert-gas blanketing and bottle-headspace gas. 0.2 µm absolute, min. 100 sterilisation cycles.
Sterilising-grade double-layer PES membrane as the final membrane before bottling — chosen per wine. LRV ≥ 7 (ASTM F838).
Sterile vent for fermentation, maturation and storage tanks — 99.99998 % related to 0.2 µm, min. 100 sterilisation cycles.
Hydrophobic PTFE membrane breather, 0.2 µm, for wet off-gas on tank vents. Up to 100 forward steam cycles of 30 min at 135 °C.
Sintered stainless for SIP of sterile-filter housings. Welded end caps, to 210 °C.
Every element carries the paperwork your QA and production teams need before it ever contacts your process gas or product stream.
Send us a P&ID, a flow rate, or just the duty — inert-gas blanketing, tank breathers, final wine membrane or bottle-headspace gas. We size the train, specify the elements and supply the documentation.
