Columns for distillation or filtering can be built to a variety of sizes and can be furnished for atmospheric pressure, or designed for internal and external pressure. All materials are available including stainless steel, nickel alloys and reactive metals. Columns can be provided in many material finishes and weld finishes, from mill sheet and plate to a polished 320 grit surface and welds varying from an “as welded” condition to a highly polished sanitary, or corrosion resisting finish.

Trays and packing mediums can be added as an option, and can be factory installed prior to delivery.

Whatever the distillation or filtering requirement of the vessel, including batch or continious operation, we can build a column to meet most applications. We have expereince fabricating many types of column, including:

  • Binary
  • Multi Compartment
  • Multi Product
  • Extractive
  • Azeotropic
  • Jacketed Kettle Reboilers

We can also design a system around your column tank to include pumps, pressure/temperature measuring equipment, and lifting/filling equipment.
