Static mixer for

Mixing elements

Geometries of mixing elements and their use

U + A is offering various designs of mixing elements.
The selection of the mixing elements and the required number depends on the mixing task.
As possible materials, we offer almost all available stainless steels and plastics in sizes 3 – 2500 mm. 

Some standard forms are presented below.

Helical Mixing

Helical Mixing Elements ( the All-rounder) | Helical mixing elements are very suitable for the most applications.
The helical mixing elements generate, by the alternating arrangement of left-and right-handed mixing elements, a reversal of the rotation direction and a current division.
In the process the first mixing element generates two rotating vortices, which are performed simultaneously radially over the pipe cross section. 
On impact with the following mixing element, the first two rotating vortices are splitted into two new vortices which are forced to rotate into the other direction.
This process is repeated until the desired homogeneity is reached.
With this type of mixer, the pressure loss is low in relation to the mixing quality.
The number of elements is calculated specifically for each application.
The installation options for these mixing elements are welded in, soldered using hard solder or removable. The cutting edges can be adapted to the application, so a dead space-free design is possible.

MV Mixing Elements (for fibrous and / or granular components) | The MV mixing elements from U + A are designed in such a way that there is practically no risk of clogging when there is a high proportion of fibrous and / or granular components flowing through them. 
The individual mixing elements form tornado-like swirls which will be interwoven.
Thanks to these excellent properties, it is possible to mix in all kinds of dosing chemicals within a very short time.

MX Mischelement - Statische Mischer von U & A GmbH
MX-Mixing Elements
MX-Mixing Elements (for intensive mixing of highly viscous products over a short distance) | MX mixing elements are ideal for intensive mixing of viscous to high-viscosity laminar product flows over a short distance. Another application is dispersing gas in liquid into very small droplets. Compared to the spiral mixer, the overall length is short, but the pressure drop is high. Dead spaces are practically unavoidable, so the cleaning effort is high.

SW Mixing Elements ( special helix mixer) | The advatages of the SW Mixing Elements are similar to those of the conventional helix mixer. These mixing elements can also be designed to be permanently integrated or removable. In order to increase the mixing performance with the same design, other changes to the geometry can be made.

PEW Mischer - Statische Mischer von U & A GmbH

PEW mixer (for emulsions or for liquid – gas – dispersion) | The PEW mixing elements are best suited for the production of emulsions or gas-liquid dispersion. The ceramic material used is suitable for most aggressive media. This material is also well suited at high temperatures (for example in exhaust gas cleaning). 

All Mixing – Elements are manufactured specifically for the application.

Production takes place in Germany in order to keep delivery times short and to be able to react quickly to changing customer needs.

We do not only offer mixers, but solutions for our customers, so contact us for creating the best solution to your application.

Mixing elements fixed or removable

In the case of metallic materials, the permanently installed mixing elements can be welded in the pipe or alternativly soldered in the pipe without gaps by using nickel solder, this offers the advantage that there are no nests or gaps for the product to deposit.
Removable elements are placed precisely in the pipe, so the operator has the option of removing the mixing elements for cleaning purposes. 
Which installation variant is suitable for you depends on your application, we would be happy to advise you.

Materials and surfaces

Materials | Almost all steels, stainless steels and plastics can be used as materials. Whether the material is chosen based on the selection of the remaining system or whether it has to have certain resistances, the mixer can in principle be manufactured in the same material. 
The steel version includes, for example:
H II, St 37, St 55, DIN 1.4571, 1.4541, 1.4535, AISI 316L, 304L, Titanium, Zirconium, Hastelloy, Monel

Plastic version for example in: PVC, PP, HDPE, PVDF, PTFE

In addition, mixer housings made of steel or GRP can be provided with linings made of PTFE, PVDF, PFA, PP, PVC or PE in order to combine chemical resistance with mechanical resistance

Surfaces | The surfaces of the pipe inner walls as well as the individual mixing elements can be delivered in different qualities.
Pipe inner walls: honed or lapped
Mixing elements: mechanically polished, electropolished

Production, Quality and Testing

We supply our Static Mixers, Heat Exchangers and Injectors in practically all obtainable precious metals and plastics in nominal widths between DN 3 and DN 2500 mm. 

Our products are manufactured in accordance with customer requirements at the facilities of our highly qualified contract partners in Germany with the following production authorisations: DIN ISO 9001, DGRL 97/23/EG, WHG § 19, AD-HP 0, Bureau Veritas, Germanic Lloyd, ÖN M 7812, § 14, BGBI Pressure Vessel Code, China Stamp, U Stamp, U2 Stamp, Det Norske Veritas. Almost no limits are set to other requirements.

This enables us to meet the highest quality and testing requirements. The manufacturing can be carried out accorsing to customers spacifications in any case.
