Nutter Ring™ random packing in different sizes
Main benefits
  • Conventional rings for a wide application range
  • Different geometries and materials available
  • Ease of replacement and storage
  • Ideal choice for systems with heavy fouling or corrosion
Main applications
  • For fractionation, absorption and stripping operations
  • For gas, refinery and chemical plants
Nutter Ring
Nutter Ring™ random packing in different sizes
Nutter Ring™

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
I-Ring
I-Ring™ random packing in different sizes
I-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
C-Ring
C-Ring™ random packing in different sizes
C-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
Plastic C-Ring
Three plastic C-Ring™ in different sizes for random packing
Plastic C-Ring™

Plastic C-Ring™

  • Equivalent to the Plastic Cascade Mini Ring (CMR) 
  • Better capacity & efficiency than Pall Ring with low aspect ratio of 1:3 (height/diameter) 
  • Lower pressure drop 
  • Available in PP, PVC/C, PE, PVDF, ETFE, PFA
P-Ring
Five P-Ring™ in different sizes for random packing
P-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
Plastic P-Ring
Plastic P-Ring™ for random packing
Plastic P-Ring™

Plastic P-Ring™

  • Equivalent to Plastic Pall Ring
  • The most common plastic random packing type used in industry
  • Available in PP, PVC/C, PE, PVDF, ETFE, PFA
R-Ring
R-Ring™ random packing in different sizes
R-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
S-Ring
S Ring
S-Ring™

S-RingTM

  • 100% equivalence to Raschig Super-Ring, a well introduced ring type in the petrochemical industry
  • One of the first so called high-performance rings
  • Well established in a number of licensed process technologies
  • Alternating wave structure prevents entanglement of individual pieces
