OptiMix® reactor: The efficient technology

This patented design enhances heat transfer, solids suspension and distribution, gas dispersion, gas flow rates and mass transfer.

The OptiMix glass-lined reactor's performances are based on the integration of three baffles onto the vessel wall. This leads to a notable improvement in the capacity of the mixture and in heat transfer compared to the standard DIN series.

The result is that all the nozzles remain free for the process. This arrangement considerably improves the hydrodynamics by using an optimized baffling effect. 

The profile of the paddles prevents the accumulation of crystals in the event of crystallization. This design satisfies two of industry's primary requirements: optimal process efficiency and improved cleanability of the reactor, as well as a reduction of the amount of dead zones which generally occurs with a standard, nozzle-mounted baffle.




  • OptiMix reactors are lined with DD3009 glass for superior corrosion resistance.
  • A complete range standardized from 6.3l (glass) up to 25m3 (Glass-lined).
  • Working conditions:
    • Pressures from full vacuum to 6/10 bar
    • Temperatures from -30°C to 260°C
  • The OptiMix reactor range is fitted with an integrated sensor on the shell which enables control of very small reaction volumes.
  • Equipment is interchangeable with standard reactors of the same size. OptiMix comes standard with two coil zones and a GlasLock® agitator, with optional jacket.
