Ideal agitating for homogeneous liquids
The GFR large-blade agitator developed specifically for tough flowing substances combines proven Stallkamp quality with a fundamentally new concept. The computercalculated agitator blades are made from high-strength cast polyamide with steel reinforcement. Their large diameter ensures that the mass remains permanently on the move, gases can escape more easily and heat is distributed evenly in the digestate tank – creating optimum conditions for bacteria. At the same time, the low rotational speed means that very little energy is consumed. The agitation effect is dependent on the density and viscosity of the liquid as well as on the contents of the tank and its shape. The GFR, combined with the agitation properties of the Stallkamp TMR, ensures an optimum agitation result.
