OptiMix® Baffles

OptiMix is a patented baffle design that optimizes the mixing performance of glass-lined reactors by integrating three baffles on the vessel wall.  This design enhances heat transfer, solids suspension and distribution, gas dispersion, gas flow rates, and mass transfer through improved mixing, making it a preferred design for chemical and pharmaceutical applications.  It also eliminates the need for top entry baffles, freeing up an additional nozzle for process use.

Additionally, a new enhancement to the design, called OptiMix-HE, circulates the thermal fluid contained in the half-coil reactor jacket through the baffles for even more process optimization. OptiMix-HE increases heat transfer area 25% or more, enabling better homogeneity, faster thermal management, and shortened cycle times.



  • Lined with 3009 glass for superior corrosion resistance  
  • Sized to fit vessels from 30 gallons
  • Pressures from full vacuum to 90/150 psig
  • Temperatures from -20°F to 500°F
  • Also available in QVF borosilicate glass reactor designs



  • Improved CIP efficiency by eliminating the difficult to clean top head pocket at the baffle/nozzle interface
  • Vortexing and splashing are significantly reduced, resulting in less product drying and sticking to the heated wall above the liquid surface
  • The symmetrical baffling of the OptiMix reactor reduces shaft deflection and extends seal life by minimizing the bending loads that are imposed on the agitator shaft
  • Get new technology without needing a new vessel - OptiMix baffles can be added to existing equipment during reglassing

BeaverTail Baffles

Reactor with beavertail baffle

The high performance, flange-mounted BeaverTail baffle features no-entry installation and removal.  The flange-mounted design reduces the possibility of leaks through gaskets or packing, since only one gasket is required for a seal.  Further testing of the design shows performance of the BeaverTail baffle is superior to finger baffles and equivalent to “h”-style baffles at any liquid level.  At liquid levels one-quarter full or less, BeaverTail baffle performs far superior to any of these older configurations.


  • Lined with 3009 glass for superior corrosion resistance
  • UniTip Type DR temperature sensor is standard on all BeaverTail baffles
  • Sized to fit vessels from 200 to 30,000 gallons
  • Headroom approximately equal to the length of the baffle is required for installation



  • No special maintenance (e.g. no stuffing box to pack, no packing to tighten and replace)
  • Absence of packing eliminates the possibility of product contamination that is prevalent in traditional installations
  • Fits on one of the standard reactor nozzles for easy installation

Combination Dip Pipe/Baffle

The innovative combination dip pipe/baffle provides three functions in one piece of equipment:

  • Baffling - The BeaverTail baffle design creates a superior mixing environment even in the most demanding process conditions.  It surpasses finger baffle performance at any liquid level.
  • Sampling - The dip pipe portion of the baffle enables samples to be taken during vessel operation, eliminating the hassle of having to stop production to obtain samples.  In addition, when samples are taken during the mixing process, a more accurate specimen can be captured.
  • Temperature Measurement - A DDPS SVR removable cartridge type temperature sensor (100Ω RTD) is optional and housed in the left tube.  Because there is no metal thermowell or gasket exposed, maintenance is stress free. The temperature sensor can be removed or replaced while the vessel is still in service.


  • Lined with 3009 glass for superior corrosion resistance and meets cGMP requirements for cleaning
  • Flange-mounted for easy and inexpensive installation
  • Installation requires an 8” nozzle or larger.  A bellows, expansion joint or flexible hose must be used in conjunction with the dip pipe/baffle to compensate for the thermal expansion of the inner pipe
  • Materials of construction including glass-lined, PTFE, Halar lined, Hastelloy, other alloy construction



  • Baffling, sampling, and temperature measurement can all be performed from a single nozzle, freeing up additional nozzles for other process piping
  • Can be installed without having to enter the vessel and cause unwanted delays in production
