Trapezium (TRZ) and hydrofoil stirrers (HF)

The Gronfa trapezoidal agitators (TRZ) are used, among other things, for the preparation of butter and cheese. As the agitator decreases in width, the peripheral speed is evenly distributed in the tank.

Hydrofoil agitators (HF) can best be compared to a stretched Rotomix PR. Just like a propeller, the blades are slightly angled and slightly curved for an optimal volume stream.
