Maintenance and service contracts

Every production environment has different maintenance, availability, and response time requirements. For some installations, preventive maintenance is enough, while business-critical processes require fast intervention.

That is why Callens Group offers several maintenance and service contracts. From basic service with 24/7 availability to full-service support with proactive monitoring and a dedicated Unicus Engineer, you choose the support that suits your installation and your production process.

“The right service formula does not start with standard maintenance, but with the impact downtime has on your production process.”

Questions? We have the answers.

No. We can only provide you with a fast service if you have a maintenance contract with Callens. We can only carry out our high-quality interventions on installations we know inside out and maintain according to our own standards.

Yes. Heroïx is a monitoring tool that can be selected as an option with every service formula. The tool automatically collects data about your installation and sends reports and notifications directly to your organization. This gives you continuous insight into the performance of your installation and flags deviations quickly. If you also want active follow-up of these notifications, the Unicus formula is the way to go. Within this service contract, the data from Heroïx is continuously followed up by the specialists at Callens Group. Deviations are analyzed, proactively followed up, and may lead to targeted maintenance or service actions.

Yes. The different service formulas are built as a growth model. As your production process evolves or the availability of your installation becomes more important, your contract can be expanded with a higher service level or additional services such as remote monitoring or Unicus full-service support.

That depends on the criticality of your installation, the impact of any production downtime, and the desired response time. For some companies, a basic service with 24/7 availability is sufficient, while other production environments need guaranteed intervention times or proactive monitoring. Our specialists analyze your situation and advise on the service formula that best suits your operations.

Before concluding a maintenance or service contract, Callens Group maps your installation and maintenance needs. Based on this, we propose a contract and, at a later stage, a maintenance schedule. We define the intervention and response time arrangements and ensure that our service teams have the necessary technical information. This allows us to act quickly and efficiently during maintenance or in the event of a malfunction.
