Koch-Glitsch conventional random packing technologies are suited for both new column designs and retrofits, offering engineers a flexible, durable, and well-documented solution for a wide range of separation challenges.

BETA RING® Random Packing

High vapor capacity and efficiency with high liquid handling capacity. 

  • Strategic placement of slots and tabs provides an extremely effective use of packing surface area.
  • Variation in the length of the internal tabs ensures high efficiency and optimal distribution Uninterrupted flow of gas and liquid.
  • Provides additional drip points to enhance liquid film surface renewal for improved mass and heat transfer.
  • Well suited for applications where low pressure drop and high liquid handling capacity are important. 
CASCADE MINI-RINGS® Random Packings

High capacity and low pressure drop with high mechanical strength that allows use in deep beds.

  • Higher efficiency and capacity than FLEXIRING®
  • Low aspect ratio promotes vertical ring orientation
  • Exposes interior and exterior surfaces to flow
  • Geometry maximizes surface utilization
  • Large vertical openings reduce pressure drop
  • Vertical alignment improves mechanical strength
ETAPAK Random Packing

Engineered for biological wastewater treatment, ETAPAK random packing delivers high surface area, excellent liquid-air contact, and strong mechanical performance in both aerobic and anaerobic systems, in applications including domestic, industrial, and refinery wastes. 

Two sizes offer flexibility for roughing, polishing, and nitrification applications.

ETAPAK 120
Ideal for high-rate filters and roughing stages in overloaded or underperforming systems.

  • Up to 95% biochemical oxygen demand (BOD) removal
  • Suited for single- or two-stage high-rate filters
  • Excellent for new installations or plant capacity expansions
  • High structural strength for deep bed operation

ETAPAK 210
Designed for polishing stages and nitrification, including aquaculture applications.

  • Over 85% BOD removal plus nitrification
  • Effective on mixed industrial and domestic waste streams
  • Commonly used in fish farming and tertiary treatment
  • Maintains biological stability under variable loads
FLEXIRING® Random Packing

A dependable, economical choice for general separation needs, FLEXIRING® random packing offers reduced pressure drop and reliable performance in a wide range of services. Its open cylindrical design supports efficient vapor-liquid contact and strong mechanical integrity.

Metal FLEXIRING Random Packing

  • Industry-standard equivalent to Pall rings
  • High mechanical strength and structural durability
  • Resists fouling, erosion, and upsets
  • Ideal for refinery, chemical, and high-load services
  • Available in high-strength variants for lighter weight and added strength

Plastic FLEXIRING Random Packing

  • Corrosion-resistant construction for aggressive chemical environments
  • Higher liquid hold-up and residence time
  • Less sensitive to liquid distribution quality
  • Suitable for applications where metal is not viable
HY-PAK® Random Packing

An enhanced alternative to FLEXIRING® or Pall ring designs, HY-PAK® features a 1:1 aspect ratio, increased finger count, and stiffening ribs for improved strength. Its geometry supports higher capacity and lower pressure drop—making it a reliable drop-in replacement for similar-sized FLEXIRING or Pall rings without sacrificing efficiency.

  • Improved geometry for higher capacity and lower pressure drop
  • Stiffening ribs increase mechanical strength
  • Maintains separation efficiency despite larger size
  • Compatible with existing FLEXIRING® or Pall ring installations
  • Suitable for retrofits seeking performance gains without tower modifications
IMTP® Random Packing

IMTP® packing merges the benefits of traditional saddle shapes with modern ring-style performance to deliver high efficiency and low pressure drop. Widely applied in distillation and absorption services, it is a reliable solution for demanding operations.

  • Combines saddle and ring-style design advantages
  • Lower pressure drop at equivalent vapor/liquid loads
  • High efficiency for improved mass transfer
  • Suitable for distillation and absorption columns
  • Recommended with INTALOX® Packed Tower Systems for optimal performance
INTALOX® SNOWFLAKE® High Performance Random Packing

A high-performance packing offering excellent separation efficiency, low pressure drop, and enhanced liquid hold-up, ideal for air stripping, absorption, and environmental applications.

  • High separation efficiency and capacity
  • Performs reliably across a wide operating range
  • Verified >99% removal efficiency in air stripping tests
  • Low pressure drop reduces blower/compressor energy use
  • Saves over 50% in energy costs vs. #1 plastic saddle
  • Strong geometry supports deep beds for high-transfer duty
