Gear units for reactors


More Information


The term “reactor” is used in the chemical industry to refer to special apparatus (e.g. a stirred tank reactor) in which educts are reacted to obtain a desired product.

The reactors for this kind of application are designed to meet very high process and safety standards.

Powders and suspensions such as pastes, doughs etc. are dried in a mixer-dryer-reactor. The drying process that takes place inside the reactor is often required to be rapid yet simultaneously gentle on the product.

The gear units must therefore have a very high efficiency and produce only minimal vibration and noise. It should also be possible to monitor the complete gear unit.
