Overview

With all the benefits of the DCM medium-speed mixers which run at up to 3600rpm, the DCH provides additional performance by pushing speeds up to 60,000 rpm (DCH25) to give rotor tip speeds up to 80 ms-1. These high speeds combined with the hydraulic shearing action of the DCH mixing head are ideal where a dispersion performance boost is needed over conventional high shear mixers. The DCH neatly fills the gap between the DCM and UMH ranges for low to medium-viscosity fluids in sub-micron dispersion, de-agglomeration and emulsification applications.

Details

Description

Based on Maelstrom's patented FDM mixing geometry, the DCH is a high speed version of the DCM mixer that extends dispersion, de-agglomeration and emulsification performance into the sub-micron region.  High speed machine tool spindle drives are used to provide fast, stable and reliable operation at speeds up to 60,000 rpm (DCH25) in production applications and this delivers tip speeds up to 80 ms-1 for consistently high quality results.  The DCH is no more difficult to maintain and operate than any conventional high shear mixer and can be used a replacement where a performance boost is needed.

Available with a range of options for stator, bearing and drive cooling, noise suppression and sealing, the DCH is highly customisable for most fluid mixing duties where conventional high shear mixers are just not able to deliver the required performance.  Hygienic and flameproof versions are also offered.
