VSP® Tower Packing

MACH Engineering’s VSP® arch ring is a type of tower packing formed from a single sheet of metal. Its unique spherical shape maximizes surface-area-to-void-space ratio while providing structural integrity and mechanical strength. The sizes of Arch Ring are proportional in all dimensions for accurate scale-up. The result is a unique packing material that delivers significant performance improvements over a standard pall ring design.

Use VSP® tower packing in a variety of industrial applications that require minimal pressure drop. For detailed specifications, contact MACH Engineering directly.

Product Overview

MACH Engineering VSP® rings have a spherical shape that is proportional and symmetrical in all dimensions, allowing for accurate scale-up without the risk of nesting. They feature heavy ribs for added strength, making them suitable for use in high bed heights. A series of longitudinal perforations create tabs that fold inward — a unique design element that promotes the formation of small, trickle-down droplets that improve liquid-gas mixing and distribution.

We manufacture our VSP® tower packing in 1″, 1 1/2″ and 2″ sizes, using the following materials:

  • VSP Tower Packing304 and 316 stainless steel
  • 304L and SS316L low-carbon stainless steel
  • Carbon steel
  • Aluminum
  • Titanium
  • Copper

For the best corrosion resistance, choose stainless steel, aluminum or titanium. For cost-effective strength in non-corrosive environments, choose carbon steel.

Benefits and Applications

MACH Engineering VSP® ring packing offers several benefits, including:

  • A 15 to 30 percent improvement in flux compared to pall rings
  • A 20 to 30 percent reduction in pressure drop compared to pall rings
  • Even gas and liquid distribution
  • Large void space
  • High strength-to-weight ratio
  • High mass and heat transfer rates
  • High throughput capacity
  • High flooding point
  • Low wetting point

Clients typically use our VSP® arch ring packing in purification, washing or vacuum distillation towers — or any application involving materials that aggregate or decompose easily. Specific use cases include atmosphere-vacuum distillation, synthesis ammonia decarburization or desulfuration, and ethylbenzene, isooctane or methylbenzene separation.
