JRWB mixers

Jongia’s type JRWB is especially suitable for mounting in the vessel bottom. The mixer is provided with a gearbox to have the correct ratio between propeller diameter and shaft speed to achieve the best process result. Mounting is easy thanks to the flange construction. The mixer is, depending on the medium, provided with a single or double mechanical seal with a seal liquid system. The JRWB mixer is suitable for applications with low to medium viscosities.
This design of mixer is suitable for mixing of different liquids and keeping a substance homogeneous.

Fermentation & Bioreactor Mixing Process
Bioreactors and Fermenters are culture systems to produce cells or organisms. They are used in various applications, including basic research and development, and the manufacturing of biopharmaceuticals, food and food additives, chemicals, and other products. A broad range of cell types and organisms can be cultivated in bioreactors and Fermenters, including cells (like mammalian cell lines, insect cells, and stem cells), microorganisms (like bacteria, yeasts, and fungi), as well as plant cells and algae. The words “Bioreactor” and “Fermenter” are basically the same thing.
