Tellen. After Sales & Service
Service & Support
For us, delivering a system is only the beginning of a long-term partnership. Our after-sales team ensures that your machines remain reliable, efficient, and up to date throughout their entire lifecycle – from spare parts supply and preventive maintenance to technical upgrades and modernization projects.
Spare Parts & Quality Assurance
Minimize downtime. Maintain performance.
Unexpected production downtime due to missing components can be costly. To prevent this, we develop structured spare parts and wear parts concepts for every system based on detailed analyses of machine configurations and operating conditions.
This ensures the availability of critical components, shortens response times, and helps maintain consistent production quality and system performance.
Maintenance & Service
Proactive. Predictable. Efficient.
Our commitment does not end with commissioning. As a long-term service partner, we support customers with comprehensive maintenance and service solutions designed to maximize machine availability.
Remote diagnostics allow rapid fault analysis and troubleshooting, minimizing downtime and reducing response times. When required, our service and software engineers are available for on-site support.
Regular preventive maintenance helps identify wear at an early stage, avoids unplanned shutdowns, and extend the service life of critical components. Customized maintenance agreements provide additional security and ensure long-term operational reliability.
Machine Self-Diagnostics
The System Monitors Itself.
Modern production systems generate valuable operational data every day. Our machines utilize integrated self-diagnostic functions that continuously monitor system status in real time.
Potential deviations from normal operating conditions are detected automatically, providing early indications of maintenance requirements or process irregularities.
This capability supports both predictive maintenance and quality assurance, enabling operators to reduce downtime, improve process stability, and increase overall equipment effectiveness.

Retrofit & Modernization
Proven mechanics. Modern technology.
Many industrial machines are mechanically designed to operate reliably for decades, while electronic and control components often reach the end of their lifecycle much sooner.
Our retrofit services provide a cost-effective way to modernize existing equipment. Depending on requirements, we upgrade control systems, renew electrical installations, integrate new functionalities, and replace obsolete components.
The result is a production system that combines proven mechanical reliability with the performance, efficiency, and capabilities of modern technology.
Before implementation, existing machine layouts are carefully analysed, previous modifications are reviewed, and all new components are seamlessly integrated into the existing system architecture.
For many customers, retrofit projects represent the most economical alternative to purchasing new equipment while protecting their investment in existing production assets.
