Proactive maintenance with VEO ensures uninterrupted operations and the best possible availability.
At VEO, we are committed to extending the lifetime of our customers’ plants proactively. For us, being proactive is not just a philosophy, since it refers to the numerous ways we can monitor and test any essential function in a plant’s automation, instrumentation and electrification systems. As our customer, you will define the extent that VEO’s proactive maintenance services are carried out at your plant.
Customised tests and measurements
We customise our proactive measures to the specific plant’s needs and requirements. After closely listening to our customer’s wishes, we will jointly agree to run any number of tests, measurements or updates, from one to the entire range available. Measures are taken partly in connection to site visits and, even more cost-efficiently, through remote access. All the details of our proactive measures will be reported to the customer in the maintenance documents.
The replacement of worn-out parts is considered as one aspect of proactive maintenance. Likewise, the remote access itself is tested at regular intervals to ensure the connection.
