Key Functions

• Versatile Filtration: It is a single solution capable of filtering both "clean" products like wine and high-solids mixtures like lees (tank bottoms).
• High Quality: It produces a final product with turbidity below 1 NTU while preserving the liquid's organoleptic characteristics (taste, aroma, and color).
• Adjuvant-Free: The system eliminates the need for filtration aids like kieselguhr (diatomaceous earth), which reduces waste and product loss.

Technical Specifications for the 4-Module Unit 

• Capacity: Average filtration capacity is approximately 2,000 hl/h for medium-turbidity products.
• Power: Consumes roughly 9 kW.
• Construction: Entirely built from AISI 304 stainless steel and typically mounted on a mobile skid with swiveling wheels.
• Automation: Available in semi-automatic or fully automatic versions, with the latter using a PLC to manage filling, filtration, and washing cycles without operator intervention.
