The C-Ring is an alternative metallic packing media that is particularly suited to use in deep packed beds.
The performance characteristics of this packing media include:
Capacity vs Pressure Drop
Lower aspect ratio increase capacity and reduces pressure drop
Lower tendency to nest
Lower tendency to nest, which means less channeling and fewer dry spots
More resistant to fouling because a combination of its vertical alignment and open sides, allow any solids present to be flushed downwards through the packed bed.
It possesses good mechanical strength, which allows its use in deep packed beds that have a higher hydraulic capacity.
