Cowl-Disk Impellers are primarily designed for gas-liquid dispersion and gas absorption applications, such as in fermentation or oxidation processes. They feature a disk with a cowl or protective structure surrounding the impeller, which enhances the distribution of gas throughout the liquid. The cowl aids in minimizing the power consumption of the system by reducing vortex formation and ensuring a more uniform distribution of the gas phase. These impellers are ideal for processes involving high gas flow rates and are widely used in industries such as biotechnology, food processing, and chemical manufacturing.
Mixing Tips for selection of Cowl-Disk Impeller
Gums & Thickeners:
- Powder should be added as fast as possible to avoid viscosity buildup. HSD OR Rotor Stator should be designed to rapidly hydrate or disperse the powder.
- This will achieve agglomerate free solution with better productivity.
Mixing of High & Low viscosity Fluids:
- Start with low viscosity fluids as it will require smaller machine. Addition of high viscosity fluid should be at flow suction of impeller.
