Having formed the company of VELO in 1950, in 1985 the two Velo brothers separated and a new company called VLS Technologies was formed. Since then, VLS focused on filtration solutions and have been awarded on numerous occasions for technological innovation, especially for cross-flow technologies (twice at SIMEI in recent years). The shared history with VELO allows VLS to supply spare parts for most equipment manufactured by the now defunct VELO company. This includes retrofitting filters, presses and other equipment with ‘’new generation’’ PLC controls etc. In South Africa, CDS Group is the authorised reseller for the various filtration solutions (conventional & membrane), offered by VLS.
Conventional filtration solutions
Rotary drum vacuum filter
VLS rotary drum vacuum filters can filter a wide range of beverage products and food liquid, as wine, lees, musts, soft drinks, sugary syrups and many more.

The VLS Membrane filter press for lees can separate the liquid part from suspended solids in an easy and effective way, being particularly indicated for the filtration of lees and musts. It is equipped with sheets of various sizes from 400 x 400mm to 1000 x 1000mm and filtering plates made of polypropylene.

Standard cross-flow filtration: Wine, cider, grape juice etc.
Automatic cross flow filter (TMF-A) for small to medium producers
With the standard version of VLS’s fully automated cross-flow filter, it is possible to use from 3 to 12 membranes, for a maximum filtering surface of 120 sqm., avoiding the usage of kieselguhr and other filtration adjuvants. An innovative, ecological process to filter wine, grape juice, cider, spirits, beer and other non-viscous beverages.

Automatic cross flow filter (TMF-I) for large scale producers
Fully automatic largescale version of the TMF-A, but can be equipped with up to 84 polyether sulphone (PES) membranes for a filtering surface of up to 840 sqm.

Semi-automatic cross flow filter for wine, grape juice & ciders (TMF-SA)
The TMF-SA is a cross-flow filtration system especially developed for wine, cider, and grape juice clarification. The results achieved are mainly due to the special capillary polyether sulphone membrane having internal diameter of 1,5 mm. Although not fully automated, this semi-automatic version is still inclusive of; Feeding pump controlled by frequency control, Stainless steel prefilter, Recirculation pump, Capillary polyether sulphone filter membranes, Pressure sensor with digital display in the inlet and outlet of the filter elements, Digital flow meter., Stainless steel tank for cleaning purpose equipped with water filter, Control board in stainless steel with PLC for control and setting of the filter parameter.

Specialised cross-flow filtration: High solids products
Lees & must cross-flow filtration (TLS)
The TLS Filter with its stainless-steel membrane is an advanced solution for cross-flow filtration of products such as lees and wine musts. It offers an automatic, economical filtration, filtered wine is perfectly brilliant and clear (<1 NTU) and the filtered product can be used without undergoing any additional treatment (fining and filtration). The recovery percentage, depending on the load of the filtered products, is higher than what is obtained with rotary drum vacuum filters and the filtered product is of better quality (analytic parameters are maintained). Thanks to remote control, the presence of the operator is minimal, thus ensuring easier and automatic operating process. Specifically dedicated to the treatment of “tank bottoms’’, it is equipped with a stainless-steel membrane adapted to very clogging products such as fining lees, bentonite, and centrifuge sludge. The membrane is long lasting and resistant to pressure, temperature and chemical products, allowing for reliability of the filtration and the capacity of regeneration of the membranes. Clogging is contained on the surface of the membrane which allows for more consistent removal of solids from filterable area, thus allowing for longer, more productive filter cycles. The filter is steam-sterilisable and the filtered product will not lose quality or alcohol.

Lees & wine cross-flow filtration (Unico)
The VLS Unico cross-flow filter is an integrated design for small & medium manufacturers needing to filter their products (wines and lees) with a “single” solution to a turbidity below 1 NTU. Filtering media can stand repeated regenerations with warm water and detergents, implying a longer lifespan.
