Reduced Corrosion & Scaling.
Optimized Blade Design.
In PA reaction tanks, the co-current agitator generates force in nearly the same direction as the fluid flow. This design, combined with a low surface concentration gradient, significantly reduces gaseous corrosion and shaft scaling.
The agitator blade is engineered for optimal positioning in the speed-critical zone. Despite having smaller blades than PBT agitators, it delivers superior performance.
Its compact critical-zone diameter and slower radial current minimize tank-wall damage, thereby extending the reaction tank’s service life.
