Redundant Control System
No unintentional unit standstill

The availability of a unit is a key requirement in the modern and international mechanical engineering.

A high availability with a very long MTBF (mean time between failures) is, however, not always sufficient for many processes. Even a very short failure (which is always possible to the laws of statistics) may interrupt the process, causing an unintentional standstill.

In particular in the chemical industry with its complex processes, a short malfunction can cause considerable downtime and recommissioning costs.


Highest availability

The unit availability is not only calculated with help of the MTBF but also from the ratio 
 

This means that even a very high MTBF does not mean a 100% availability. This goal can be reached only if the MTTR (mean time to repair) is zero.

Voith tries to reach the goal MTTR -> 0 with their redundant control technology. However, contrary to the known redundant systems using three signals and a series-connected design 2 out of 3 voting, Voith relies on 2x100% channels.

With regard to technology, Voith uses a redundant control system with a redundant I/H converter. So Voith offers a complete solution for new installations and for the retrofit of existing units where unit availability is required in particular.
