Mellapak™ and MellapakPlus™

Some Mellapak™ and MellapakPlus™ types are also available in different kinds of thermoplastics. Packings made of polypropylene (PP), post chlorinated polyvinylchloride (PVC-C), polyvinylidene difluoride (PVDF), Teflon® PFA and polyether ether ketone (PEEK) can be supplied.

Key characteristics

  • Large number of transfer units per meter, low HTU, depending on the system
  • Small pressure drop per meter packed height
  • Most economical load range up to F factor 4 √Pa
  • Maximum operating temperatures: approximately 110°C for polypropylene, approximately 150°C for PVDF
