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!
