UV System Retrofit & Revamping
We upgrade existing UV systems where intervention is genuinely needed: power supply, control, lamp housings, automation, safety and energy efficiency.
Tell us about your UV systemAn older machine is not necessarily a machine to replace.
Before proposing replacement, we analyse what can be retained, what limits the process and where investment can provide a real benefit.
A solution built around the process.
Electronic power supply
We assess replacement of traditional systems when it can reduce energy use and improve controllability.
PLC, HMI and protocols
We update control logic, diagnostics and industrial communications.
UV system and machine integration
We work on the subsystem while respecting existing machine geometry and production requirements.
Understand first. Then design.
Survey
Measurements, constraints and machine condition.
Diagnosis
We identify the real critical issues.
Engineering
We retain what still has value.
Testing
We verify the result on the actual process.
Technology visible in the details.
Lamp housing replacement
UV lamp housing replaced on a Müller Martini machine.
Power and control
Electrical panel for the Müller Martini revamping with seven UV lamps.
An effective retrofit starts with what is worth preserving.
We do not replace components as a matter of principle. We assess system condition, spare-parts availability, safety, process stability, installed power, cooling, wiring and automation to distinguish what can continue to operate from what limits reliability and productivity.
Assessment of the existing system
Lamp housings, reflectors, power supplies, transformers, electrical panel, PLC/HMI, ventilation, extraction and safety devices are analysed as one system.
Electrical revamping and control
We can upgrade power supply, power regulation, electrical distribution, PLC, HMI, interlocks, diagnostics and machine communications while retaining mechanically sound parts where possible.
Testing and commissioning
A retrofit concludes with checks of functions, sequences, interlocks, alarms, thermal behaviour and testing on the actual process. The final system must remain maintainable and understandable after the work is complete.
Müller Martini: renewed UV treatment capability on a machine with many years of service.
An older printing machine can still retain significant production value. In this project we worked on the UV system of a Müller Martini machine in an application where curing the printed product was particularly demanding.
Working speed reached in the specific application, with a print that was difficult to cure.
The challenge
The challenge was to combine an existing machine with a UV treatment suited to the printing requirements. Because curing was particularly demanding, process setup was central: line speed had to be evaluated together with the result on the printed product.
The intervention
We replaced seven lamp housings and built a new electrical panel with seven power supplies, one for each lamp. The intervention integrated the new UV units into the existing machine, connecting the equipment installed on the line with its electrical power supply.
The real-world result
In this specific application, operation reached up to 250 m/min. This was significant for a machine with many years of service and for a print application that was difficult to cure. This speed refers only to this documented case: materials, inks and process conditions must be assessed for every new application.

For a screen-printing customer in Veneto, Italy, we upgraded a system while retaining the machine's original structure. The intervention included replacement of the power section, control system and extraction system, together with an overhaul of the lamp housings.
The intervention focused on the functional groups of the system while retaining the existing mechanical structure.
Before deciding on a retrofit.
If the issue concerns a single component, start with service and UV spare-part identification. The assessment helps distinguish a localized repair from a system upgrade.
When is upgrading preferable to replacing the machine?
When the structure, mechanics and basic process are still valid but power supply, automation, lamp housings, safety or spare-parts availability limit reliability and productivity. The assessment must consider the system as a whole, not a single component.
Can part of the existing system be retained?
Yes, if the retained components are technically compatible with the new architecture and do not introduce safety, maintenance or performance issues. A retrofit starts by distinguishing what still has value from what needs to be replaced.
What information is needed for an initial assessment?
Photographs of the system, available electrical diagrams, lamp and power-supply data, dimensions, line speed, installed PLC/HMI, recurring faults and intervention objectives.
Is testing included in the intervention?
Yes. We verify sequences, interlocks, alarms, power supply, thermal behaviour and operation on the actual process before considering the revamping complete.
Before replacing the machine, let's see what it can still become.
We start from your production process, materials and the result you need to achieve. The solution comes afterwards.
