Our reactor agitators are indispensable components in a wide range of chemical and industrial processes:
Delivering precision-engineered mixing and dosing solutions across diverse industrial sectors with reliability and performance.
Computational Fluid Dynamics (CFD) helps our engineering team study how the impeller moves liquid inside a tank before finalizing agitator speed, impeller diameter, shaft position and baffle arrangement. For industrial impellers, CFD visualization is useful for reviewing circulation, velocity distribution, turbulence level and possible dead zones.
At Premix Technologies, CFD review supports practical agitator and impeller selection for blending, solid suspension, heat transfer, gas dispersion, slurry handling and process mixing applications. The video below demonstrates how flow lines and velocity distribution can be reviewed to improve mixing efficiency and reduce uneven circulation inside the vessel.
