FAQ

Q: What are the advantages of the screw impeller design?

A: The screw impeller is specifically engineered for low-speed operation in laminar flow conditions. It creates a consistent axial circulation pattern as liquids move along the helical surface. This design is particularly effective for mixing and heat transfer in medium to high-viscosity liquids, providing thorough and gentle mixing without excessive shear forces.
