PARAVISC-KOAXIAL

For Changing Low to High Viscosity Products and Demanding Requirements

An agitator system with independently operating wall and central impellers that can run with different shaft speeds and in both rotational directions. It is ideal for alternating low to high viscosity products with demanding requirements for homogeneity.
EKATO PARAVISC-KOAXIAL
In principle, the multi-purpose EKATO PARAVISC-COAXIAL agitator system can be used for every kind of mixing task. This system is generally chosen for very complex mixing processes and for products with extreme flow behaviour. The EKATO coaxial mixing system can be easily tailored to particular vessel geometries and process requirements. From the technical point of view, there are virtually no limits to its range of applications.

The primary tasks for a coaxial agitator are homogenizing, dispersing and heat transfer. The maximum processable product viscosities depend on the respective type of impeller, and are generally about 1 million mPa ∙ s. Coaxial impellers can therefore be used for processing steps that were previously only carried out with kneaders or extruders in which flow anomalies were unimportant. Examples for typical coaxial systems are special polymers, resin emulsions or different kinds of pastes

Disintegration of solids as well as dispersing and homogenizing are mainly carried out by the central agitator. Mixing tasks in low viscous process phases can also be carried out by the central impeller (e.g. EKATO VISCOPROP or Dissolver). The diameter ratio, number of stages and blades, pumping direction, tip speed and input power are specified according to the respective material properties and process data. The EKATO PARAVISC, usually rotates with a constant speed and is responsible for quick blending in the high-viscosity range. It also continuously transports product close to the vessel wall back into the zone influenced by the central impeller. In low viscous process phases, e.g. the initial phase of a batch process, the peripheral frame impeller also acts as a baffle. When diluting highly viscous masses, it prevents the formation of a thin lubricating film on the vessel wall and thus stops undesirable rotation of the entire vessel contents.

This impeller also provides particularly effective heat transfer due to the narrow clearance to the vessel wall. Additional, scraper elements keep the vessel wall clean, provide an even higher heat transfer rate and prevent localised overheating, deposits and incrustations. The combined effect of the central and frame impellers guarantees very homogeneous and high-quality products at considerably shorter blend and/or batch times.

  • Use of wall and central impellers operated independently of one another in both rotational directions PARAVISC ensures short mixing times and efficient heat transfer
  • Central impeller enables high local power input with dissolver and extremely good surface motion and a further reduction in the blend time with Viscoprop
  • Products with extreme non-Newtonian characteristics
  • Ideal for multi-product plants
