Random Packings

Our extensive portfolio offers traditional and high-performance random packings, including Nutter Rings™, I-Rings™, C-Rings™, P-Rings™ and R-Rings™. This makes us a one-stop solution provider for all your column and separator internals.

Information

Nutter Ring™

  • High-performance random packing designed by Dale Nutter in 1984 
  • Efficiency is enhanced by lateral liquid spreading and surface film renewal 
  • Superior surface utilization allows for shorter packed beds 
  • Extensively tested by the Fractionation Research Institute (FRI), making the Nutter Ring one of the best known high-performance random packings 
  • Geometry provides maximum randomness with minimum nesting and maximum mechanical strength

Nutter Ring™

I-Ring™

  • Equivalent to the Intalox Metal Tower Packing (IMTP), the industry‘s first and most widely used high-performance random packing introduced in the late 1970's 
  • Geometry ensures low liquid hold-up and a significant improvement in capacity compared to Pall rings

I-Ring™

C-Ring™

  • Equivalent to the widely used Cascade Mini-Ring (CMR) 
  • Evolution of Pall ring employing a much lower diameter-to-height ratio favoring orientation that results in lower pressure drop and higher capacity 
  • Excellent mechanical strength 
  • C-rings excel within random packing in fouling media

C-Ring™

P-Ring™

  • Equivalent to the widely used Pall ring 
  • Designed by BASF AG around 1940 based on the Raschig ring 
  • Punched “shovels” leave “windows” on the outside, facilitating vapor flow and increasing capacity compared with the R-Ring 
  • Extensively tested by research institutes worldwide

P-Ring™

R-Ring™

  • Equivalent to the widely used Raschig ring 
  • Employing a diameter-to-height ratio of ~1 makes the Raschig ring the first “designed” random packing, introduced by Fritz Raschig at the end of the 19th century

R-Ring™
