Q-PAC®: The Art of Engineering

A Major Advance in Packed Tower Technology

High-capacity Q-PAC creates exciting new possibilities in packed tower design. Q-PAC's patented structure uses drip points and gas turbulence to create millions of small droplets, multiplying the surface area for gas-liquid contact with minimal resistance to gas flow.

Revolutionary Drip Point Technology

Traditional packings like saddles or Pall Rings spread liquid over extended plastic surfaces—a two-dimensional design where the liquid film facing the packing itself doesn't participate in mass transfer. Q-PAC works differently.

Q-PAC's flow-through structure of thin grids and rods provides drip points that break streams of water into torrential rain of tiny droplets. These droplets fill three-dimensional space, with each presenting its entire surface area to the passing gas phase. The total surface area far exceeds that of conventional packings, while air flows through with minimal resistance. Turbulent gas flow further breaks liquid into smaller droplets, maximizing surface area per unit volume.

Higher Capacity & Flexible Equipment Sizing

Q-PAC operates at gas velocities exceeding 600 ft/min—roughly twice conventional packing velocities of 350 ft/min. This enables dramatic equipment downsizing: smaller tower diameters, reduced pumps, lower blower motors, and compact mist eliminators. One documented installation saved over $500,000 versus conventional packing designs.

For existing equipment, Q-PAC retrofits boost capacity at a fraction of new tower costs. Scrubbers switching to Q-PAC operate at higher velocities while achieving superior removal efficiencies.

Outstanding Fouling Resistance

Q-PAC's uniformly spaced bar-and-rod geometry and superior wetting capability promote self-cleaning by eliminating dry spots. This minimizes plugging from mineral scale or biological growth, reducing maintenance downtime and making Q-PAC ideal for scrubbers using reclaimed water.

Cost-Effective Solution

Q-PAC's low weight per cubic foot reduces material costs, particularly for specialty thermoplastics needed for heat and corrosion resistance. Combined with smaller equipment sizing and reduced operating costs, Q-PAC delivers exceptional value across the project lifecycle.
