Mixer systems made by THALETEC are based on a technology that was developed in the course of many years of experience and tradition. Like our reactors and tanks, the mixer systems are coated with high-resistance technical glass. Our engineers calculate your optimum mixer system on the basis of your material data in order to provide you with the guarantee to obtain the best possible performance and optimal mixing results from your system. Specifically adapted calculation software and the latest manufacturing processes ensure reproducible processes and a precise fit of all components.

For the most important components of the mixer system motor, gearbox and mechanical seal we rely on the products made by renowned German manufacturers. Made in Germany!

THALETEC offers a wide variety of mixer systems from which we choose the optimum for your requirements.


TRD 125K to 250K
For small reactors with a nominal volume of up to 1,000 liters, short drive designs with a jacketed gearbox support and assembly holes that are covered with protective perforated plates are available. The gearbox connection is provided by an intermediate flange; the mixer and gear shafts are linked by a sleeve coupling to DIN 115.












TRD 300S to 900 S
This design provides for the lateral removal of the mechanical seal without removing the gearbox. The distance between the mixer shaft and the gear shaft corresponds to DIN 28161, therefore, all mechanical seal assemblies to DIN 28138 can be attached to the system. Both shaft ends are linked by a special THALETEC sleeve coupling.

All drives size 300 or larger are equipped with a mixer support that is attached to the mixer system flange and used to hold the mixer in place outside the reactor during assembly works.







TRD 300K to 900K
For nominal volumes of 1,600 liters or more, short drive designs with welded tubular feet gearbox supports are provided. In addition to high stability, they ensure optimum accessibility for assembly work. The mixer and gear shafts of these drives are again linked by a sleeve coupling to DIN 115.

A protective cage made of perforated plate has been fitted around the rotating parts.
The mechanical seal can be removed upwards, and the intermediate flange and gearbox have to be detached from the gearbox support for this purpose.






Modular system
TRD drives have been constructed in modular design, therefore, the various drive types can be combined with any desired type of gearbox and motor arrangement (using motor adapters, belt drives, bevel gear).

Shaft seal / Lubrication system
Compact units to DIN 28138 with complete lubrication systems are used:

• liquid-lubricated mechanical seal with thermosiphon system, with circulating pump and temperature sensor in the seal housing, if necessary
• gas film lubricated mechanical seal with barrier gas system
• GMP-compliant or sterile mechanical seal with rotating mating ring for special shaft end and mixer nozzle in split flange design
• shaft lip seal

The mechanical seal can be replaced using the THALEMAIL-QuickXange rapid exchange system

The advantages of the THALETEC high-performance mixer systems at a glance:

• Motor arrangement according to customer requirements: in-line, perpendicular to the mixer axis, or suspended in parallel to the mixer axis (with belt drive)
• use of commercially available gearboxes
• extremely good accessibility of the mechanical seal and the coupling because the mixer system is provided in an open, three-leg frame construction
• coupling halves remain within the drive stand and do not have to be lifted out when the coupling screws have been removed
• mixer shaft is mechanically stable at all times and positively fastened in order to ensure that the mixer shaft cannot slip down and fall into the apparatus
• due to the strict observation of the relevant DIN standards, the mixer system is universally exchangeable and can be attached at any time to DIN reactors
• shaft seals of all renowned manufacturers can be used without any restrictions, such as wet-running, dry-running contacting and gas film lubricated mechanical seals
• Additional units can be easily attached to the drive stand at any time
