MONTZ Standard Metal Sheet Packing Type B1

The high-performing sheet metal packing

MONTZ-Pak Type B1 is the result of years of experience and development in the field of thermal separation technology with structured packings for mass transfer.  MONTZ-Pak Type B1 has proven its performance in many technical applications.  The exceptional properties are possible through the regular geometrical arrangement of corrugated sheets and its particular MONTZ surface structure.


  • Large throughput capacity
  • High flexibility
  • High separation performance, close to capacity limits
  • Low pressure drop
  • Liquid loads from 0.1 to over 250 m³/(m² h)
  • Adaptability to every separation problem through variable, specific surfaces


  • Atmospheric columns and high pressure columns
  • Absorption of components and contaminants from gas and air flows
  • Natural gas drying with Glycols
  • Refinery columns (atmospheric and under vacuum)
  • Petrochemical columns
  • Exhaust air decontamination in Aluminium rolling mills
  • Lubricating oil and rolling oil processing
  • Waste water stripper
  • Retrofits of existing plate columns or packed columns for performance improvement

Separation steps:

  • Depending on the type, >5 theoretical separation steps per meter are achieved.


  • Stainless steels such as 1.4000, 1.4301, 1.4404, 1.4571 1.4435, 1.4539, and others
  • C-steel
  • Hastelloy C4, C22, C276, Aluminium, Copper, Titanium, Monel, Tantalum
  • Additional materials are available upon request


  • The performance of existing columns such as crude oil columns, natural gas drying, vacuum distillation (for fatty alcohols, fatty acids, Methyl ester etc.) can be improved with upgrades.

Column data:

  • Diameters ranging from 40 mm to 11 m and wider
  • Liquid load from 40 l/(m² h)
  • Operating pressures from vacuum to above 100 bar
  • Minimum liquid hold-up


  • Packings are manufactured as single pieces or in segments. Packing installation is done through column shell flanges or manholes, as desired.

Inclination angles of wave channels:

  • Standard version with 45°
  • 60° for larger liquid throughputs and direct heat exchangers in condensation beds
  • Additional angles on inclination available upon request

Available packing types:

45° (Standard version) 60° (for large throughputs)
