Modern but nonetheless hip – simply retro and yet somehow beautiful. The popular retro trend could be described in exactly the same terms. But what exactly does "retro" mean for a machine? And what exactly is a retrofit?

Retro derives from Latin and means something like "backwards". I.e. a trend from an earlier period suddenly becomes very fashionable again. The English word "fit" is perhaps best translated into German as "passend". A retrofit, therefore, is when an old machine that is past its prime is reconfigured for current technical conditions. Here you will find out exactly how this works.

What is retrofit?

"A retrofit includes various measures aimed at increasing the efficiency and performance of the machine."

Norbert Süß, Head of Service, Retrofit at Baumüller

A retrofit includes various measures aimed at increasing the efficiency and performance of the machine. Both individual components and complete drive systems can be upgraded. Often a machine controller will be upgraded and a modern operating unit (HMI) will be installed. Modern digitization tools can of course also be added for remote service or a diagnostic tool. All of these lend new shine to the old machine and enhance its performance enormously.

Reasons for retrofit

The replacement of obsolete components to meet the standards of state-of-the-art technology increases the productivity and energy efficiency of machines. With a retrofit, you as a system operator can benefit from significantly lower costs compared to the acquisition of new production systems. Here, the basic substance of your machine, usually very stable and high-quality, is preserved and in case of large machines there is no major expenditure incurred for replacements, such as for building a machine base, for example. The production downtime is thus greatly reduced thanks to a retrofit.

Advantages of a retrofit:

Modernize while saving energy
Saving energy can be that simple: With a well designed retrofit, it's possible.

Increase machine availability
High output needed: Fewer machine failures increase availability significantly.

Long-term increase in efficiency
We realize your individual requirements: This results in an increase in the efficiency of the machine that will last.

Improve replacement part availability
There for you in the future as well: Guaranteed replacement parts supply for your modernized machine.

Manufacturer-specific solutions for modernization

Regardless of manufacturer, we offer you tailored and multi-level solutions for modernization of your electrical drive systems. With new drive components and control solutions you will quickly achieve greater flexibility and increase the productivity of your system – and while keeping investments at a manageable level. We equip existing machines with the most modern drive systems, control technology and user interfaces, thus allowing high system availability and process reliability.

Retrofit examples with different machine types

1. Extrusion machines

Common reasons for retrofitting extrusion systems include energy savings (in some cases up to 50 percent is possible) and replacement part availability. Because of in some cases very high energy savings, the investment in a retrofit often pays for itself in two years.

Your benefits at a glance:

  • Significant savings in energy consumption
  • Reduced space requirements of your machine
  • Low-maintenance drive elements for increased availability of your machines
  • Increased overall efficiency of the drive system
  • PLC in the drive and external temperature regulation
  • Replacement part availability

2. Printing machines

Common reasons for the retrofit of printing machines are replacement part availability and machine availability. As printing machines have a very robust design, there is no need to replace the machine. In these cases a retrofit or a partial retrofit is entirely sufficient to achieve the productivity of a current machine.

Your benefits at a glance:

  • Time and cost savings through modernization instead of acquiring a new machine
  • Future security through guaranteed replacement part and service availability
  • Increased reliability through modernized technology

Retrofits of electrical motors and converters

With new drive components you will quickly achieve greater flexibility and increase the replacement part availability of your system – and while keeping investments at a manageable level. Retrofitting existing machines to state-of-the-art drive systems allows high machine availability and process reliability.

Optimized solutions according to plan

After an inventory and analysis of currently installed drive technology, we will create a detailed quote for your company covering your optimized drive systems for the retrofit.

Based on your requirements, we will plan and define parameters for a drive system outfitted with the latest technology. In addition, we offer, along with the drive modernization, detailed training of your personnel in the new system so that you can enjoy the benefits of the drive modernization.
