# [Retrofit - Europe's underestimated superpower](https://vion.swiss/en-de/vion-blog/retrofit-europas-unterschätzte-superkraft)

Used machines don't write heroic songs. They simply run - **day after day**.  Europe owes them **stability, supply and prosperity**.  But behind every roar of the presses and whirring of the pumps lies a silent weakness: **their silence.**  
**80% of our infrastructure** works in the shadow of digitalization - **reliably, but blindly.**

### **Integrators in the machine room - what the industry is really struggling with**

Digitization **has long been part of everyday life**for **integrators**, but one with many pitfalls. There is a lack of **scalability** in the project business : every customer mandate starts from scratch, **legacy systems speak different languages**, hardware interfaces are patchwork. **Margin pressure** is the daily bread, because pure hardware no longer generates profits and competition is based on **price rather than quality**.  
Added to this is the **shortage of skilled workers** - the best minds keep developing similar solutions instead of creating valuable standard modules. Many integrators are driven by the desire for **more service, less crisis mode and predictable revenues.**

### **Challenges - digitalization in the brownfield is not a sure-fire success**

Anyone who works in **existing plants** knows that the **technical diversity** is enormous. Every second project requires new interface technology, and **old systems are difficult to connect digitally**.  Systems do not speak the same language - from **serial RS232 to modern bus protocols**, everything is represented.  Integrators also encounter **regulatory pitfalls** and complex security requirements, especially in **KRITIS areas.**  
Without **ready-made sets of rules**, **open interfaces** and **automated audit logs**, every project becomes a **one-off solution.**

We could resign ourselves to leaving everything as it is - or sink billions into new buildings. But anyone who knows Europe's industrial DNA knows that true progress begins **where old substance meets fresh intelligence.** The magic word: ***retrofit.***

### **Observation is annoying - action counts**

**Industry 4.0** likes to talk about futuristic factories and artificial intelligence. The reality? A **meshing of old and new**, **analog and digital**, **steel and code.**  
Most systems have **no data interface**.  Dashboards show temperatures and running times at most - but they **don't change anything**.  
**Observation is no substitute for action.** Outside, people don't optimize, they **improvise.**

**Retrofitting changes the game:**  
A **sensor doesn't just measure** - it sounds an alarm, triggers maintenance, starts emergency operation or throttles energy - **during operation.**  
A **gateway** sharpens the view of the status of entire networks, controls **pumps, heating systems, cooling systems and emergency power generators** in a decentralized manner.   
Suddenly, monitoring costs **just a few hundred euros** instead of millions.

### **Solutions from the heart of life**

- **Bornemann Gewindetechnik - IoT retrofit for precision machines**  
  Bornemann is a traditional **German medium-sized company** specializing **in threaded spindles and precision manufacturing**.  Instead of investing in new machinery, the company decided to **retrofit its existing milling machines** - some of which are over 25 years old.  
  Together with an IoT integrator, **vibration, current and temperature sensors**were installed to  connect each machine to an **edge gateway**. This collects data in real time, detects deviations and forwards them to a cloud platform.  
  Bornemann developed **its own maintenance indicators**based on the data obtained : if the vibration exceeds a defined limit value, a **maintenance order is triggered**.  
  In the first six months, the number of **unplanned downtimes**fell **by almost 40%** and **production output increased by 8%**.  Today, the retrofit system is **integrated** into **production planning** - each machine sends its **health status directly to the scheduling department.**
- **MAN Energy Solutions - Digital retrofitting of large compressors**  
  MAN Energy Solutions in Oberhausen modernized decades-old **industrial compressors** in power plants without replacing them. These units, which weigh several tons, are at the heart of many **energy and chemical processes** - a breakdown costs millions.  
  By integrating **vibration, pressure and oil sensors** as well as **intelligent control boxes**, the compressors were  incorporated into the in-house **"Turbomachinery IoT Suite".**  
  AI models analyze operating data every second and compare it with historical patterns. Early warnings **appear automatically in the control center** even before any damage can be measured.  
  Result: **40% fewer unplanned downtimes**, **25% lower maintenance costs**.  The system also allows **remote maintenance via secure VPN connections** - technicians can **intervene in real time.**  
  MAN is now using the retrofit as a template for **international decarbonization projects.**
- **Stadtwerke Augsburg - smart water management through digital retrofitting**  
  Stadtwerke Augsburg operates an extensive network of **pumping stations, wells and treatment plants** - many of which date back to the 1970s. Instead of investing millions in new buildings, the utility opted **for gradual digitalization through retrofitting.**  
  **Old control systems** were **retrofitted** with **IoT gateways**, while pressure, level and current sensors supply data to a **Siemens cloud platform.**  
  This  automatically detects **leaks, inefficient running times and abnormal energy consumption.** In the event of heavy rainfall, the system reacts **autonomously**, opens **relief shafts** and equalizes **pressures between pumping stations**.  
  The result: **15 % less energy consumption**, **20 % less maintenance** and **fully automated documentation** in accordance with **the Water Resources Act and BSI guidelines.**  
  Augsburg is thus considered a **pioneer among German municipalities in** terms of how to **transfer** existing infrastructure **into the digital age - without replacing it.**

Every sector, every solution, a pattern: **digitalization is not built - it is connected.**

### **The new logic - retrofit platforms that really scale**

Anyone thinking retrofit through to the end today is relying on more than isolated solutions. The key is a **platform** that connects different **technical systems with each other**,  remains**retrofit-capable** and **modular** - regardless of the age of the systems and free of proprietary boundaries.

**What is important?**

- **Manufacturer-independent connection:** Machines, pumps or infrastructure are integrated flexibly and without a project marathon.
- **Plug-and-play interfaces:** Standard protocols (e.g. Modbus, OPC UA, MQTT) replace special programming - **integration becomes child's play.**
- **No-code control logic:** engineers define **rules and regulations using drag-and-drop**, without developers behind them.
- **Security and compliance** are automatically included: **encrypted transmission**, **rights management** and **auditable logsensure regulatory security** - in energy, KRITIS or franchise networks.

Those who want long-term scalability rely on **platform models** in which **templates and automation modules** can be reused as required once they have been developed.   
Integrators and operators thus create **predictable revenues**, **service products (white label, SaaS, OEM)** and **new markets - without the bottleneck of the individual project.**

In short: the future of inventory digitization belongs to **flexible, active retrofit platforms** - as a foundation for **independence and growth.**  
**VION**pursues this approach  as an **open, scalable and industry-agnostic platform.**

### **Conclusion - connecting the future instead of building the future**

*Retrofit is **not a compromise**, it is **Europe's superpower.***  
***Efficiency, operational reliability and new business models** are created **where analog legacy meets digital controllability.***  
*Value is created **where digitalization does not remain isolated**, but becomes a **shared, actively controllable platform**.*  
*The future does not begin with the big switch - but with **small, clever connections** that **get the best out of the existing system.***
