NETZSCH-OMEGA for dispersion of high viscosity products

The Omega does not require grinding media, has extremely low wear, low maintenance cost, high throughput, and is suitable for high viscosity products. The new Omega series of Netzsch is a revolutionary design in dispersion applications. It has special pressure cavitation and valve structure at the end along with the feed pressure at the head. Dispersion is achieved when the powder slurry passes through this series of cavitation. The Omega has a batch design and can also switch to a circulation model. It is very easy to use and can be integrated to existing processes of a factory. The premixed slurry only needs to be connected to the inlet of the Omega and equip it with a high pressure pump for feeding.

The greatest feature of this machine is that it is suitable for dispersion of high viscosity products (150,000mPas). It is no longer to reduce viscosity first when you intend to disperse powder with particle size in the nano range into solutions with high viscosity; Omega can directly achieve dispersion in high viscosity solutions.

Furthermore, the Omega is also suitable for dispersion of regular viscosity products. Compared with agitator bead mills, the Omega does not need to use grinding beads, reducing cost on consumables. Also, the high throughput of the Omega saves time cost for enterprises. In the case of Omega2000, each batch is calculated in tons, and the largest model is the Omega 4000 (4000L per hour).

Temperature rise was also considered when developing the Omega, and the new cavitation design enables the machine to achieve dispersion at lower pressures (10~700bar); the largest temperature rise is only roughly 20°C because it does not need to use pressures of conventional machines at 2,000bar and above. Using only 1/3~1/4 of the pressure also represent lower energy consumption and wear cost, making expenses even more competitive in long-term operations.

The special design of Omega allows the height, depth and width ratio of materials to be maintained after dispersion.

Comparison of Omega and conventional High Pressure Homogenizer (HPH):

The figure below shows that Omega (working pressure of 700bar) achieves greater fineness under the same number of batches compared with conventional HPH (working pressure of 1,500bar), and had lower temperature rise by 24 C, not only reducing energy consumption and machine wear, but also increasing production.

NETZSCH announced the latest laboratory grade dispersionizer Omega 1 in 2015

As an extension of the widely applied Omega mass production series, Netzsch announced the latest and smallest model this year with the minimum single batch of only several hundred milliliters.

It has the same operating principles as the mass production model and adopts a

combination of pressures and special cavitation design, so that even for only a small volume the dispersion results are unquestionable under the same energy efficiency and production rate.
