Static mixer CompaX™

High mixing efficiencies at short mixing and installation length

The Sulzer CompaX™ static mixer is the most efficient and most economic choice for admixing additives in the turbulent flow regime at highest flow ratios. Thanks to its low pressure drop, it significantly saves pump energy and thanks to its high efficiency, it massively improves the consumption of additives therefore offering both economical and ecological benefits.

Save pump energy with low pressure and high flow
Main benefits
  • Efficient mixing (CoV</= 0.05)
  • Lowest possible pressure drop compared with other conventional mixers
  • Short installation length: approximately 0.3 to maximal 1 x pipe diameter
  • Optimized dosing point for additive mixing, no injection lances required
  • Robust construction and no clogging (open geometry)
  • Plug and Play (installation and operation
  • Excellent price/performance ratio
  • Mixing ratios from 1:10 up to more than 1:10 000
  • With only one feed point per mixer up to 6 additives can be injected simultaneously (for bigger, special CompaX only)
Main applications
  • Chemical industry
  • Water and wastewater industry (desalination plants, governmental wastewater treatment, etc.)
  • In water or wastewater treatment, the CompaX™ mixer is used, for example, to admix flocculators, to admix agents or for pH adjustment, to admix chemicals for disinfection, etc.

Key characteristics

The Sulzer CompaXTM static mixer consists of a highly efficient mixing device with an integrated dosing point. The additive is fed into the zone where there is a strong turbulent flow. Fluids, additives, and gases are mixed reliably and effectively over a very short distance. For larger pipe diameters, you can admix up to 6 additives using only one mixing element. The pressure drop of a Sulzer CompaXTM mixer is approx. 8 times lower compared to orifice-type static mixers. For low-viscous fluids, it is typically 10 – 100 mbar. This results in significant savings on pump energy, which pays off economically as well as ecologically. You will not experience any clogging problems with this mixer thanks to the open-wing geometry and the additive dosing location.
