About retrofit GmbH


The retrofit GmbH consists of a highly efficient team of business specialists and service providers, works according to proven and modern standards, solutions and methods, and always has the customer's benefit in focus.

It's our job to streamline operations and support you in retrofit so you can focus back on the core of your business.

Special ways and solutions to think outside of the "box" distinguishes us, even if it gets a bit more stressful. We keep a cool and professional head.


At the end of the day, the goal is to identify and implement efficient and cost-effective solutions for the customer in order to avoid extremely expensive new purchases or control retrofits. Because if a machine or plant performs its task well and "only" the computer or the electrical components represent a recoverable risk, there is no reason for unnecessary expenses.

Maschine IT retrofit
Understanding of Work

The retrofit GmbH deals with the IT retrofit of (older) machines and plants, which are affected by a failure of the installed PCs, as well as the repair of electronic components and their (re-) procurement.


We modernize your computer-aided systems and machines so that new purchases can be avoided and existing machines can continue to operate safely, stably and cheaply.


In summary, the problem of failure is solved by old Windows or DOS PCs, which control a machine or take over recording tasks in order to increase machine availability significantly.

In most cases, the machines themselves are mechanically ready, but can not be operated reliabel due to the failure of the implemented PC hardware, which usually allows only the alternative of an extremely expensive new purchase.

This production downtime and risk is pre-empted by migrating the machine software to contemporary hardware 1: 1 without changing the software itself to just 1 bit. This means that the machine does not "notice" that the old control PC has been replaced and is much more stable again.

If further, considered critically considered electrical components are available, we procure these and / or repair them on a component basis, and give a corresponding functional guarantee to cover all the relevant components of the machine incl. Computer.


As a result, the operator can continue to produce, the probability of default is significantly reduced, there are no extreme investment costs for a new machine.

In addition, a data backup can be retrofitted in the new hardware, the subject of time synchronization is covered, the time required to generate reports drops significantly.


Thus, our customers save an extremely expensive and time-consuming new acquisition of machines, which is basically not necessary.


In all cases, a feasibility study is started which, if positive, leads to a risk analysis of the system and the retrofit.

For dedicated pharmaceutical systems, the GMP-compliant document creation and implementation of IQ / OQ for clean GMP documentation is added, as well as for all systems a well-founded follow-up of the machines and plants.


The technical and documentary feasibility was proven to reference projects, with the purpose to support the machine operators sustainably, and to lead their "old", insecure machines to new stability and security, and at comparatively very low cost.
