Low speed stirrers (SRW and KRW)
Gronfa Sigma agitators (SRW), also known as countercurrent agitators, are always multi-stage and have angled tips. The tips provide additional mixing effect, but due to the low speed this agitator can also be used for sensitive products.
Gronfa cross beam agitators (KRW) do not have upright tips and are used for more general applications. The agitator blades are angled at 45 degrees.
Both agitators are available in any size. They can also be perfectly combined with a downward following residual agitator. A foot bearing is often used for long axles.
