Discover the Benefits of Bottom-Entry Sanitary Mixers

Bottom-entry mag mixers for poly tanks bring valuable benefits, including improved product purity and much easier handling, cleaning, and maintenance. They eliminate the risk of particles falling from overhead bearings or seals used in top-entry models.

Thanks to gravity, bottom-entry models have proven more efficient, requiring a fraction of the time to thoroughly mix materials as compared to top-entry mixers. We’re positive you’ll enjoy the boost in profits and may be cleaned without requiring the mixer agitator and shaft to be removed or cleaned separately

Why not use a bottom entry sanitary mixer for all aseptic mixing?

Some media doesn’t require the intense mixing and shearing of a bottom-entry sanitary mixer, and may mix satisfactorily with other more compact mixer styles. Aside from that, various applications require autoclaving or portability as primary necessities.

White Mountain Process offers sanitary mixing systems designed so you may enjoy the savings of consistent results, easy maintenance, and convenient mixing.
