VFF NetBall®

High-performance in ball form: for absorption and desorption.



The new NetBall® has been devised by VFF's research and development division and sets new standards in the field. Its favourable flow profile, combined with a high specific surface, offers top mass-transfer properties with an extremely high hydraulic load capacity and minimum pressure drop. As with all VFF plastic random packings the VFF NetBall® also has a specially abraded surface which results in extremely good wetting even on first use. Its specially designed net structure guarantees high mechanical stability and results in an optimum bed constitution.

The VFF NetBall® is easy to handle when emptying and filling the column. All of which saves time and money!

Upon request VFF NetBall® is suitable for drinking water according to KTW recommendations.

Press report

VFF NetBall® celebrates its world premiere at Hannover trade fair

Siemens VFF NetBall

With the presentation of numerous innovative products and proceedings the Hannover trade fair lived up to its reputation as the world's most important event in the technology world.

The impressive 4,500 m² Siemens AG booth was a particular magnet for the public: Around three quarters of the approximately 220,000 trade fair visitors confirmed that Siemens was justified in its position as the key player in international competition. The strategic aim of the company, to supply innovative techniques and pioneering problem-solutions for the most diverse industries, was manifested in four towers which could be seen from far away, each of which was dedicated to one of Siemens extensive range of technology applications.

In the chemical industry tower, for instance, Siemens demonstrated the manufacture of biodiesel and fitted an imposing extraction column with the VFF NetBall®, a world innovation designed and produced by "Vereinigte Füllkörper-Fabriken GmbH & Co. KG" which was launched here for the first time to a wide audience.

The VFF NetBall®, which can be used for all thermal separation processes, has a particularly good flow profile combined with a high specific surface which guarantees optimum mass-exchange characteristics with an extremely high hydraulic-loading capacity and minimum pressure drop.

As with all VFF plastic tower packings, the VFF NetBall® also has a specially abraded surface which results in extremely good wetting even on first use. Its specially designed net structure also guarantees high mechanical stability and results in an optimum bed constitution. The ball shape of the VFF-NetBall® permits easy handling during column-filling and -emptying. All of which saves time and money!The VFF NetBall®

naturally complies with drinking water requirements according to the KTW recommendation.

The VFF NetBall® - a product which sets new standards.
