    New Product

    We are proud to present the next step for industrial scale membrane filtration, introducing the new Vibro-I 80 m² unit!

    The new Vibro-I unit is the next step in scaling your processes, whether it’s separation, clarification, concentration, purification or something different, the Vibro-I can do it all. Same with our other units, our Vibro® technology enables high yields, high recovery, gentle product handling and requires only minimal energy.

    CEO and Founder, Henrik Hjelmsmark, says “with the newest addition to our Vibro-I series, we have had to rethink the design to accommodate for the large capacities that we targeted. But our team has worked tirelessly and continues to take membrane filtration to new heights by achieving this important milestone in making Vibro® technology the new industry standard for filtration processes”.

    When using Vibro® technology, scaling your production has become drastically easier, and takes you all the way from process development to full scale production. Vibro-I units are modular and can be interconnected to give you unlimited capacity. With the introduction of the new size, reaching large scale productions, has become even simpler.

    The new Vibro-I unit is already in action in production of biopharmaceuticals, algae and alternative proteins.

    New Product

    The last touches have been finalized, and we are ready to officially release our newest solution for benchtop filtration, the Vibro-LabEV, along with its unique membrane module, Vibro-Lab280.

    Our CEO, Henrik Hjelmsmark, says “The Vibro-LabEV will fill the gab between our small Lab35 and our work-horse, Lab3500. It utilizes all the unique advantages of our technology and adds another level of flexibility as the drive fits membrane modules of different sizes”. This means that you can now switch between modules with a membrane surface of either 280 cm² or 2 × 35 cm² using the same unit.

    The Vibro-LabEV’s filtration process is identical to our larger units, meaning that the Vibro-LabEV is ideal for process development as you can run simulations of large-scale operations on a small unit and you can mimic the scaling process itself on the different membrane modules. Of course, the small footprint of just 30x15cm and its simplicity and user-friendliness also make it the ideal choice for laboratory work.

    Change in ownership

    SANI Membranes ApS now has Martin Glensbjerg as co-owner of the company where he joins the Board. Martin Glensbjerg is one of the original founders of the successful company Chemometec A/S, a worldwide supplier of equipment for laboratories. SANI Membranes has developed a groundbreaking Membrane Filter Technology and products that fit for Laboratories and for industrial production for separation and concentration of media in Biotech, Pharma, Green Proteins and Liquid Foods.

    We are proud and happy to have Martin on board, as Martin has extensive experience in building a similar company. At the same time, we have added capital that enables further expansion of the company, says Henrik Hjelmsmark, CEO of SANI Membranes.

    I see great opportunities for SANI Membrane’s products to make a major difference in terms of faster product development and improved yield within e.g. biotechnology and for new pharmaceutical products based on cell technology. The laboratory filters enable scalable continuous filtration of very small media streams, and as SANI Membrane’s industrial filters are using up to 90% less energy than present solutions, it is obvious to get the technology into production in many of the largest companies in Denmark and globally, says Martin Glensbjerg.

    SANI Membranes Membrane filters are based on the patented Vibro® Technology that replaces energy-consuming pump solutions. The Vibro® solution enables better filtration and is at the same time simple to use and service. The World Market for purification and separation is enormous and with an increasing focus on energy consumption, there is a need for new solutions, says Henrik Hjelmsmark, who looks forward to the collaboration.

    Vibrating Plate Heat Exchange Assembly and Device

    Our Free Flow plate design can also be used in Forward Osmosis applications and is even Patented as a Heat Exchange device as both side of the membrane is fully flushable. When configured as a heat exchanger the membrane is obviously not permeable but can be very thin and thus have high temperature exchange efficiency.

    To increase the efficiency when working as free flow plate heat exchanger the unit can be combined with the patented Vibro® Technology and in this way, the k-value – or efficiency of the heat exchanger will increase significantly, as strong turbulence is induced directly on the heat exchange surface through the vibro-function. As the vibro function only use energy on surface turbulence, the energy consumption is minimal so a very energy efficient Vibro heat exchanger can be produced – fully scalable to very large units, and with all parts in polymeric materials, whereby it is suitable for sanitary purposes and can be used with highly corrosive media.

    Pressemeddelelse 10-10-2018

    Vibro-L er en unik benchtop filtreringsløsningen nomineret til FoodTech Award 2018

    SANI Membranes har udviklet en sand trestjernet verdensnyhed i den disruptive og kompakte Vibro-L til udvikling af mikrofiltrering og ultrafiltreringsprocesser.


    Vibro-L er en 0.35 m² benchtop løsning til kontinuerlig mikro og ultrafiltrering i laboratoriet. Vibro-L er et alternativ til alt fra engangsfiltre til sanitære cross flow anlæg og kan opereres med helt uniformt transmembrantryk. Hele membranarealet er som noget nyt synligt under filtreringen, hvilket giver et helt nyt indblik i både filtrerings- og vaskeprocesser.

    Vibro-L er med dens membranareal på 0.35 m² en revolutionerende nyhed til udvikling af kontinuere mikro- og ultrafiltreringsprocesser på prøvestørrelser fra 1 liter og opad. Den udviklede proces kan direkte overføres til de industrielle Vibro-I enheder til sanitær filtrering i ekstremt energieffektiv industriproduktion.

    Vibro® Teknologien

    Den patenterede Vibro® teknologi skaber den nødvendige renholdende turbulens på overfladen af membranerne ved at vibrere membranelementet i forhold til mediet. Dette gør at Vibro-L kan køre kontinuerlige filtreringer på medier hvor engangsfiltre og ’stirred cells’ hurtigt stoppes til.

    Kontinuerlige filtreringer køres normalt i et cross flow system, hvor den nødvendige renholdende turbulens skabes af et hurtigt flow over membranoverfladen. Dette nødvendiggør en energi-krævende og hurtig recirkulering af mediet hvilket ofte skader produktet.

    Vibro® teknologien eliminerer behovet for en hurtig recirkulering, og muliggør dermed et enkelt design, hvor mediet koncentreres til den ønskede koncentration ved bare én passage af systemet, og uden at mediet ødelægges af en recirkulationspumpe. Både permeat og retentat er fuldt drænbare, så der er ingen produkttab selv ved mindre tests.


    Vibro-L anvender SANI Membranes nyudviklede Free Flow Plate™ membranelementer. Membranelementerne er udviklet med et sanitært fokus og er ekstremt energieffektive. Membranen svejses til overfladen af polymer Free Flow Plates, som derefter svejses sammen, og danner Free Flow Plate™ membranelementerne med alle deres funktionaliteter.

    SANI Membranes har membranelementer til Vibro-L med membraner med porestørrelser fra 5000 Dalton til 10 µm i forskellige materialer fra flere producenter af sanitære membraner. Membranelementerne kan nemt CIP rengøres i systemet og membranen kan genbruges igen og igen. Det er også nemt at skifte fra en membran til en anden, så Vibro-L kan benyttes til flere forskellige filtreringsopgaver på samme arbejdsdag.

    SANI Membranes på FoodTech 2018

    Vibro-L er nomineret til FoodTech Award 2018 som en trestjernet verdensnyhed og bliver under FoodTech 2018 demonstreret på stand M9674, hvor den også kan bestilles til en favorabel messepris. I øvrigt fremvises de industrielle Vibro-I enheder til sanitær mikrofiltrering og ultrafiltrering.
