NHS Rührwerk

The NHS agitators are vertical agitators with worm gearmotor. They can be used in mixing, dissolution and maintenance processes where a mild to medium mixing is required. This agitator is designed for the food-processing, cosmetic and pharmaceutical industries and it is provided with the most suitable finish for each industry. 
The NHS agitator can be used in tanks of up to 10.000 L with products of medium to high viscosity.

Funktionsprinzip

The agitators are installed inside the tank either centrally with current deflectors (baffles), or offset so that the position itself prevents the rotation of the mixed product. The rotation of the propeller makes the fluid flow to the bottom and then up to the surface of the product along the walls of the tank. The effect is enhanced if the bottom of the tank is curved.
