Generator repairs can be avoided most of the time by performing maintenance

repair of electronic groups, Agresa

The repair of generating sets can be a major expense for any company. At Agresa we have always defended that, in order to avoid greater evils, it is of vital importance to carry out all the necessary maintenance tasks that guarantee the good operation of the group under any circumstance, in addition to considerably extending its useful life.

There are two different types of maintenance; firstly, we have the preventive one, which includes all those tasks with which it is guaranteed that the generating sets are kept in an appropriate state for their use at any time. We are talking about the revision of the machinery, equipment and installations, which must be carried out periodically to avoid possible failures in the system during periods of activity. Secondly, we have the corrective maintenance, which is the one that gathers all those necessary tasks to fix a possible breakdown during its operation.
