Random Packing has been in use from the onset of industrial distillation – and it's here to stay. Lots of important separation/absorption/stripping processes have been developed relying on the special behavior of these mass transfer devices. Moreover, ease of replacement and suitability for storage make Random Packing the equipment of choice for systems with heavy fouling or corrosion.

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