Condition Monitoring

Maintenance and servicing only when there is real need

Condition monitoring enables you to plan maintenance and servicing in advance, according to your needs. Thanks to the permanent recording and evaluation of the machine condition, the current plant condition and the expected condition, development is determined individually.

The time for the next maintenance no longer has to be chosen according to fixed intervals, but can be planned far in advance and precisely according to the actual condition of the facility. Maintenance measures do not have to be carried out only when a component is defective, but when wear and tear is imminent. This makes it possible to optimise plant availability and noticeably reduce downtimes, resulting in considerable cost advantages for you.

Be informed before a failure occurs

Condition monitoring permits two maintenance strategies, a usage-based or a time-based strategy, for optimising system availability. By continuously recording and evaluating the process and machine data, the condition of individual components can be accurately represented. Long before a component reaches the end of its lifetime and causes a time-consuming and costly plant shut-down, the AERZEN Digital Platform generates corresponding advisory messages.


Required spare parts, tools and resources can thus be procured in advance and planned for the long term. The duration of the actual maintenance is thus considerably reduced and can be better planned into the operating process. Apart from the cost advantage, the continuity of operations is also improved, as the quality level is guaranteed and the need for reactive maintenance is kept to a minimum.


  • Precise fault identification
  • Possibility of preventive intervention
  • Optimisation of maintenance intervals
  • Minimisation of downtime
  • Improved safety


To address individual operating conditions, two different approaches have been developed for Condition Monitoring. If you prefer a usage-based maintenance concept (UBM), in which components are replaced after their full service life has been reached, the solution of Usage-based Maintenance is recommended. The availability management solution is suitable for a time-based maintenance concept (TBM) in which systems are linked to 24-hour operation and maintenance cannot be carried out ad hoc.

Usage-based Concept

The usage-based maintenance strategy takes the actual system condition into account. This strategy makes it possible to fully utilise the service life of components and to reduce the number of service and maintenance operations to a minimum. This ensures that maintenance is only required if it contributes significantly to maintaining a long service life of the system, thus achieving savings through minimal maintenance operations.

Usage-based Maintenance

Time-based Concept

With the time-based maintenance strategy, maintenance measures and operational concerns are coordinated, so that maintenance is only carried out when not doing so would inevitably lead to a plant shutdown. This ensures that components are replaced in good time before the end of their service life in order to avoid a system standstill and thus not to disrupt the operating process.
