Helical Static Mixer
(Type HT)

The HT helical static mixer pioneered the inline motionless mixing industry over 40 years.  It is a cost effective static mixer design with moderate mixing performance capabilities.  It is most suitable for use in small diameter turbulent flow and laminar flow applications where the mixing task is simple and where it’s characteristic features of low pressure drop and open geometric structure are best for the specific application.  For difficult applications, the high performance GX static mixer is recommended for laminar flow applications and the high performance GV static mixer is recommended for turbulent flow applications.
 
The Helical static mixer is available in metal and plastic construction in a wide variety of configurations and sizes.

The helical static mixing elements are edge-seal brazed to the tubing ID.  This allows for very high pressure drops to be taken across the static mixing elements and for enhanced heat transfer in static mixer heat exchanger applications

History of the HT Helical Static Mixing Structure
The HT Helical static mixer was invented by Arthur D. Little Company of Cambridge, Massachusetts, USA in the late 1960’s and licensed the technology to Kenics Corporation of Andover, Massachusetts, USA who trademarked the design as the Kenics Static Mixer*.  Kenics did a tremendous amount of fundamental high quality R&D work on the Helical Bowtie structure and commercialized the static mixer in hundreds-of-thousands of installations where the mixing requirements were of easy to mid-range difficulty.
