Conventional random packings
Wide portfolio of rings for your needs
Our extensive portfolio offers traditional and high-performance random packing’s including Nutter Rings™, I-Rings™, C-Rings™, P-Rings™, R-Rings™ and S-Rings™.
- For fractionation, absorption and stripping operations
- For gas, refinery and chemical plants
Nutter Ring
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™
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™
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
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
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™
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™
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-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
