VFF-Twin-Pak®

From the decades of cooperation with our customers and the intense involvement in the product, VFF can fall back on comprehensive know-how, which formed the basis of the completely new development of the VFF-Twin-Pak®, a modern high-performance metal random packing. The VFF-Twin-Pak® was developed for a circle of customers with highest demands and offers an extremely low pressure drop with the best possible mass transfer! The new VFF-Twin-Pak® is characterised by highest capacity and an excellent stability at great filling heights.

 

Extremely low pressure drop with best mass transfer

The VFF Twin-Pak®, a VFF-patent, is a completely newly designed high-performance random packing in metal with a similar profile to structured packings but which retains all the many benefits of random packings. Its form combines an extremely low pressure drop with a convincing mass transfer! VFF-Twin-Pak® is a high-performance random packing designed for maximum throughput capacity. Compared with a conventional random packing with an equivalent rated value the mass transfer of the new VFF Twin-Pak® is substantially better. The specific pressure drop of the VFF Twin-Pak® is not even a third of the level of a comparable random packing. In other words: The VFF Twin-Pak® offers optimum throughput capacity with significant cost savings!

Benefits at a glance

The VFF Twin-Pak®, a VFF-patent, is a completely newly designed high-performance random packing in metal with a similar profile to structured packings but which retains all the many benefits of random packings. Its form combines an extremely low pressure drop with a convincing mass transfer!

VFF-Twin-Pak® is a high-performance random packing designed for maximum throughput capacity. Compared with a conventional random packing with an equivalent rated value the mass transfer of the new VFF Twin-Pak® is substantially better. The specific pressure drop of the VFF Twin-Pak® is not even a third of the level of a comparable random packing. In other words: The VFF Twin-Pak® offers optimum throughput capacity with significant cost savings!

 

By means of the new manufacturing method developed by VFF and its special design, the VFF-TWIN-PAK® can convince by a high degree of design-related mechanical stability. This allows the trouble-free realisation of a great filling height in a single bed at a low weight.

When the VFF-Twin-Pak® was designed, priority was placed on the demands of the VFF customers on a high-performance random packing. Therefore, when it came to the manufacturing method, attention was paid that the customer is provided with a random packing individually tailored to his requirements. VFF-Twin-Pak® is not only available in a universal standard version, it is also supplied in a wide range of materials or wall thickness. Whether as a featherweight or extremely strong version, whether carbon steel or special alloys - with the VFF-Twin-Pak®, the customer always receives the tower packing that is perfectly suited to his application. The VFF-Twin-Pak® is individually available from 0.2 mm to 0.6 mm or in the standard wall thicknesses. An advantage that also pays off for all customers!

The VFF-Twin-Pak® offers highest throughput capacity ... at a fair price! This was only able to be realised by intense involvement with new geometries and by the new manufacturing methods developed by VFF. This modern high-performance random packing combines an extremely low pressure drop with a convincing mass transfer! In other words: Highest throughput capacity while clearly saving costs!

 

The quality of the VFF-Twin-Pak® and all other VFF products is ensured due to internal test benches and external inspections carried out by renowned, independent institutes within the framework of the certification acc. to DIN EN ISO 9001.

 

As the largest manufacturer of tower packings and inert balls in Europe, VFF is in a position to react to customer inquiries within a very short time. This saves the customer long lead times and storage costs. Individual wishes (e.g. packaging) can be realised by VFF at any time. Particularly where a contract exists with the customer, VFF is able to guarantee appropriate quantities being available at call in the desired packaging.
