Epsilon Inline Disperser

The New Inline Mixing Experience

The unique System for dispersing Solids in Liquids

NETZSCH Epsilon 

The NETZSCH Epsilon inline disperser is unique on the market. In the standard version, dispersion is not based on the conventional rotor-stator principle, in which high shear forces and a high energy input are used to disperse powder in liquid. In this version, the dispersing principle of the NETZSCH Epsilon does not use a stator through which the product flows and no narrow shear gaps between the rotating and stationary parts.

The pressure differences created by the pumping and centrifugal effect of the rotor are used to achieve the best possible wetting and dispersion of the powdered solids in liquid.

The resulting advantages are: 

  • Minimal product heating 
  • Lowest input of shear forces
  • Deareation of the product after the solid intake
  • Insensitive to small foreign objects

High availability Application Fields: 

  • Shear-sensitive products
  • Temperature-sensitive products

NETZSCH Epsilon 

For products that require dispersion with more energy, the NETZSCH Epsilon can also be equipped with a classic rotor-stator version. The dispersion principle is the same as in the standard version. Vacuum expansion of the contained air and wetting by overpressure also takes place here. However, the stator, through which the product flows, introduces significantly higher shear forces into the product.

The result is higher shear forces in the product for deagglomeration of powders that are difficult to disperse.

The Advantages of the Rotor-Stator Version:

  • More intensive dispersion of agglomerates that are difficult to disperse
  • Shorter dispersion time 

Application Fields:

  • Solids that are difficult to disperse
  • Shear-insensitive products

Operating Principle

The Epsilon works together with a product tank in circulation. After the machine is started, the liquid flows to the Epsilon and is pumped back into the tank. 

Due to the strong pumping action of the rotor, a strong negative pressure is created in the process chamber of the Epsilon. This vacuum is used to draw in the powdered solids. No external vacuum generation or addition of external air is necessary. Powder that has been prepared in a hopper, silo, bag loading station or BigBag station is automatically drawn in by the machine when the powder feed is opened. 

After the powder delivery, the powder feed is closed and, if necessary, circulation of the product continues. In this step, the enormous advantages of the dispersing system become clear: the subsequent dispersion improves the quality and simultaneously deaerates the suspension. Due to the low energy input, warming of the product is significantly reduced compared to conventional rotor-stator systems.
