Static Mixer Selection Guide

There is no one static mixer design that is best suited for all process applications. For this reason, StaMixCo manufactures a broad range of static mixer designs of different geometric structures.

Below is a short guide that will help you identify the best type of static mixer for the specific process function that your application falls under. We have taken the liberty of pointing out the design that in our opinion is best for each process function based on our experience in the industry, equipment cost, process suitability, and many other factors. Please keep in mind that our opinion may change based on specific requirements and constraints for a particular application.

Process Applications
Process Applications for static mixers fall in the below fundamental categories:

Laminar Flow (High Viscosity Materials)
  • High Viscosity Mixing
  • High – Low Viscosity Mixing
  • High – Low Volumetric Ratio Mixing
  • Heat Transfer Enhancement
  • Plug Flow Reactors
Turbulent Flow (Low Viscosity Materials)
  • Low Viscosity Liquids Mixing
  • High – Low Viscosity Liquids Mixing
  • High – Low Volumetric Ratio Mixing
  • Gas Mixing
  • Dispersion of Immiscible Liquids
  • Gas-Liquid Contacting
