Service for special machines and production plants

Why Aerne Engineering AG is the ideal service partner

Production plants, special machines and automation solutions are core components of modern production operations. Their reliability and availability directly affect productivity, process safety, quality and cost-effectiveness. Unplanned machine downtime, wear or outdated technologies can quickly lead to production stops and high follow-up costs.

_ae SERVICE is the business unit for service of Aerne Engineering AG and supports industrial companies and production facilities throughout the entire lifecycle of their machines and systems. The range of services includes maintenance and upkeep, repair and fault rectification, retrofit and modernization, as well as technical support and spare parts.

_ae SERVICE combines practical machine service with the extensive engineering expertise of Aerne Engineering AG. This enables special machines, production plants and complex industrial facilities to be analyzed, maintained, repaired and modernized holistically. The aim is to deliver solutions that not only work in the short term but also secure reliability, availability and cost-effectiveness of production in the long term.

For us, service means taking responsibility for the entire lifecycle of a plant. Regular maintenance increases the reliability and availability of machines and production facilities. Coupled with technical understanding and fast solutions, we create the foundation for a long-term safe and high-performance production.

Operator of industrial machines, special machines and production facilities need more than a provider that swaps individual components. They require a service partner who understands mechanical engineering, automation and production processes, recognizes technical interdependencies and can develop bespoke solutions when needed.

This is where the strength of Aerne Engineering AG lies. With _ae SERVICE, practical industrial service meets solid engineering competence. Malfunctions can be resolved and analyzed holistically. In modernization projects, not only components can be replaced, but technically and economically meaningful solutions for the entire plant can be developed.

This holistic approach provides a decisive added value, especially for complex special machines, recurring faults, discontinued components or upcoming retrofit projects.

With _ae SERVICE customers receive machine service and engineering from one source. Aerne Engineering AG combines solid technical know-how with a holistic understanding of machines, automation and production processes. This reduces interfaces and creates the basis for fast, sustainable and economically meaningful solutions.

Machine maintenance and upkeep

Regular and preventive machine maintenance lays the foundation for reliable production operation. Through preventive upkeep, wear, technical weaknesses and potential failure risks can be identified early, before they lead to unplanned downtime or production stops.

With _ae SERVICE, Aerne Engineering AG supports industrial companies in proper maintenance and upkeep of special machines, production machines and industrial plants. The focus is not only on the current condition of a machine.

The aim is to increase reliability, plant availability and production safety in the long term while also identifying potential optimization opportunities early. Thus _ae SERVICE helps reduce downtime risks, avoid unplanned production stops and extend the lifespan of existing machines and systems.

Machine repair and fault rectification

If, despite all precautions, a machine fault occurs, quick and competent action is crucial. Especially with automated production facilities or individually developed special machines, replacing only the affected component is often not enough.

The service technicians of _ae SERVICE support fault finding, diagnosis, machine repair and fault rectification of special machines and production plants. Thanks to the engineering competence of Aerne Engineering AG, complex mechanical, electrical and automation interdependencies can also be taken into account.

Act quickly. Understand causes. Solve sustainably.

Aerne Engineering AG's mandate goes beyond mere fault rectification. Where sensible, _ae SERVICE analyzes the cause of a machine fault and develops technical measures to reduce or prevent similar failures in the future. This way, a short-term machine repair can become a sustainable technical improvement.

Retrofit and plant modernization

A proven special machine or production plant does not have to be replaced just because individual components are outdated, discontinued or no longer available. Targeted retrofit can be an economically attractive alternative to new procurement and can make existing machines fit for future production requirements.

By modernizing controls, drives, electrical components or automation technology, existing machines and industrial plants can be technically advanced and adapted to new requirements.

Instead of looking at individual components in isolation, Aerne Engineering AG, together with the customer, analyzes which modernization is technically and economically sensible and how it can be optimally integrated into the existing production facility. In a retrofit or conversion, machine safety is also considered holistically. Aerne Engineering AG takes into account the relevant requirements for machine safety and CE conformity and assesses safety-relevant changes within the framework of the respective retrofit or conversion project.

Thus, a professionally implemented retrofit combines technical modernization with machine safety and economic efficiency. This can extend the life of a special machine, increase plant availability, optimize production processes and secure existing investments in the long term.

Technical support and spare parts for special machines and production plants

Reliable machine service for Aerne Engineering AG does not end after repair or commissioning. With _ae SERVICE, industrial companies and production facilities receive a competent point of contact for technical support and spare parts for machines and plants.

In particular with older special machines and production plants, discontinued or no longer available components can become a challenge. Proactive handling of obsolescence helps to identify risks to plant availability early. Aerne Engineering AG's engineering competence provides a decisive advantage: instead of merely sourcing a spare part, _ae SERVICE can assess technically suitable alternatives and develop solutions that can be reliably integrated into the existing machine and plant concept.

Machine service and engineering from one source

The key added value of _ae SERVICE lies in the combination of professional industrial service and comprehensive engineering competence. Aerne Engineering AG considers mechanics, electrical engineering, automation and industrial production processes in interaction and can therefore assess even complex special machines and production plants holistically.

Therefore, the service does not end with merely exchanging a component. Technical causes can be analyzed, optimization potential identified and, if necessary, bespoke engineering solutions developed for existing machines and production plants.

For production facilities this means: a single point of contact, fewer interfaces and comprehensive technical competence throughout the entire plant life cycle.

_ae SERVICE. Partnership across the entire plant lifecycle

Whether preventive machine maintenance, unscheduled downtime, repair, spare parts needs, retrofit or modernization of an existing special machine: with _ae SERVICE Aerne Engineering AG supports industrial companies and production facilities over the entire lifecycle of their machines and production plants.

The focus is on a long-term, collaborative partnership. The goal is to increase reliability and availability of existing facilities, identify technical risks early and develop sustainable solutions with the customer for economical production operations.
