Our company structure
With our comprex® process, we are a cross-industry specialist for mechanical cleaning. The variety of application areas allows us to offer our customers optimized solutions for cleaning. Be it as a service, in plant engineering and in medicine.
- For decades, we have been successfully working for numerous municipalities throughout Germany and beyond when it comes to cleaning drinking water, raw water and wastewater pressure lines efficiently and sustainably
- The comprex® process mobilizes and removes deposits and biofilms from drinking water installations of e.g. hospitals, universities, swimming pools and residential buildings.
- Due to their complex design, industrial plants and systems have special cleaning requirements. With comprex®, complex systems can be successfully applied in areas such as cooling systems, heat exchangers, machine cooling, etc.
- With our comprex® units, pipelines or production facilities are cleaned in a targeted manner by integrating our cleaning technology as an automated step in the operating processes. This permanently prevents recurring soiling and maximizes production efficiency.
- Founding investment in the start-up Comprex-Medical GmbH. The patented impulse rinsing process sets a new hygiene standard in the medical industry. With comprex® Endoprime, endoscopes are pre-cleaned automatically. This minimizes time, effort, cost and risk.

Certification according to SCCP:2011
Safety first is as much a matter of course for us at work as it is for you at your industrial site. With Hammann GmbH, an SCC – certified service company is at your disposal.
The occupational health and safety management system SCC (Safety Certificate Contractors) was implemented in our company in 2017 and audited by TÜV Rheinland (certificate number: 01 013 1700046).
With our SCCP certification level, our occupational health and safety management system includes the needs of the petrochemical industry.
Innovations and patents.
A BMBF research project is successful when patents result from it. We have been able to develop two of them from the BMBF joint project “Microbial ochreization in technical systems”. The first has already been granted as a European patent.
It is a new process that completely redefines the performance level of our COMPREX® impulse rinsing process – with the revolutionary technology of modulated air pulses. This additional tool is always used when particularly high force is required when removing deposits and water is to be saved at the same time.

Efficient cleaning
Dealing responsibly with water as a resource and ensuring its hygienic condition without harming health and the environment - that's what we do every day. Because we are specialized in sustainable and gentle cleaning completely without chemicals. In addition, we see it as our task to contribute to increasing energy efficiency with the result of our work.
Clean economically
and save time
However, our customers - whether in the municipal sector, in drinking water installations or in industry - appreciate not only the hygienic, ecological and resource-saving aspects of our work, but also the economic ones such as cost and time savings with low downtimes. And, of course, that we are thoroughly familiar with their specific tasks.
comprex® is efficient and effective
Our services in facts and figures
Acting sustainably and energy-efficiently
We are aware of our responsibility.
We at comprex® always want to get better. That is why we are also constantly looking for the even better solution to clean piping systems and their components. Research is close to our hearts and curiosity in our nature. With our test facility in Landau, which was specially set up for research, we are getting to the bottom of the possibilities for dissolving deposits – again and again.
As our practical experience has shown us, we are on the right track with the patented comprex® impulse rinsing process we have developed – but we are constantly redefining its level of performance by incorporating innovations from our research into comprex® technology.
A special feature: our own test facility. In these, we regularly test the effectiveness of our comprex® process or conduct feasibility studies with customers.
