Plastic Cascade Ring

The cascade ring random packing is an evolution of the pall ring employing a much lower diameter to height ratio. The low aspect ratio of these rings provides for high capacity and low-pressure drop characteristics. It exhibits excellent mechanical characteristics and good anti-fouling characteristics


Key Characteristics

  • FP – cascade ring is the Industry recognized CMR ring equivalent
  • High vapor capacity and low pressure drop
  • Low pressure drop and high capacity allows smaller column diameters in new installations

FP-Cascade Ring Applications

  • Flue gas desulfurization
  • Absorption
  • Stripping services
  • Gas treatment systems
  • Quench towers
