We stand for comprex®. We are competently committed to the efficient and sustainable cleaning of piping systems and in industrial pipe cleaning.

We started with pipe network cleaning in Germany more than 27 years ago. Today we offer our services not only in the municipal sector but also for drinking water installations in buildings and for industrial systems.

The Comprex impulse rinsing process works mechanically, using only pulsed compressed air and water. We see it as our task to use water as a resource responsibly and to contribute to increasing energy efficiency with our work.

Hygiene plays a significant role in drinking water supply and installation. This is what we work for and are committed to every day.

In the field of industrial pipe cleaning, we can successfully clean complex piping systems with special requirements, thereby increasing production efficiency.

We have our finger on the pulse

comprex® - industrial pipe cleaning and more

Simple but effective:

For cleaning your pipeline (e.g. in industry, buildings or municipalities) we use our patented comprex® impulse flushing process. This provides you with an effective, continuous cleaning solution that minimizes time, effort and cost, and is available both preventively and when currently needed.

We clean all types of piping systems:

Product lines, cooling and tempering circuits, heat exchangers, plant components, cooling lubricant lines, drinking water distribution networks, waste water pressure lines, etc.

comprex® removes deposits of varying degrees of hardness:

Whether loose sediments, freshly deposited dirt, germs such as legionella or even strongly adhering dirt – comprex® technology cleans with the power of mechanics. Whether it’s sludge, paint or food, the goal is to get your lines clean again and keep them clean for the long term. Regular cleaning of your equipment contributes to efficient, hygienic production.

How to do it?
In contrast to conventional water flushing, we use targeted pulses of compressed air and water. Our process therefore works purely mechanically without aggressive chemicals and still achieves the desired cleaning effect for all types of pipelines.

Our cleaning units are connected to the flushing section to be cleaned. From there, filtered compressed air is introduced into the line in a controlled and pulsed manner. Inside the pipeline – with the water remaining there – packets of air and water blocks are created, which flow through the pipeline section at high speed (up to 20 m/s).

These packages generate enormous turbulence with strong shear and drag forces that mobilize and reliably discharge the deposits on the pipe walls.

The result: clean lines and clean product – efficient, gentle and economical.

comprex® Compared to a conventional water flushing system

Water flush

comprex® process

The powerful cleaning impulses from air and water are not only effective, but use up to 90 % less water than a water flush.

The comprex® impulses reach a speed of up to 70 km/h in the pipe. In comparison, the water flush only manages 10 km/h with great difficulty.

70 km/h = 20 m/s
10 km/h = 3 m/s

The dissolving power for deposits is 10 to 100 times stronger with comprex® than with water rinsing. Cleaning is nevertheless gentle on the pipelines, as the pressure remains below the system pressure.

The focus and heart of this is the patented comprex® impulse rinsing process developed by us, which we are constantly redefining and expanding at various performance levels. This allows us to adapt it perfectly to the individual, changing tasks of our customers. As a service provider for the cleaning of fluid-carrying systems and as a manufacturer of mobile and stationary cleaning systems, we have been active in various areas and sectors of drinking water supply and industry since 1997.

Customer testimonials

"The MCU-300 from Hammann represents an important component of our innovative industrial hygiene concept. The system is used at Meffert AG both for flushing pipelines and for cleaning stand-alone systems.
The cooperation with the colleagues from Hammann has worked very well since the beginning of the project.

Project planning and commissioning were transparent and professional. All inquiries are processed promptly, and ideas and optimization requests are discussed openly with our technical department even months after commissioning.
The MCU300 is intuitive for our employees to operate, can be used almost anywhere due to its dimensions, and works very reliably."

"It is no longer possible to imagine our maintenance of injection molds without the cleaning technology from HAMMANN. The comprex® cleaning is without alternative in very many applications. Thank you for the excellent and pragmatic service."

"The cooperation with HAMMANN is excellent, we maintain a comprehensive and sustainable exchange. Our on-site meeting in Landau was particularly informative, including a tour of the test facility. comprex® can be described briefly and precisely, and the advantages are practically obvious - fast and good service to achieve a nearly new condition in terms of cleanliness.

The process allows customers to clean their plant equipment without disassembly. With regular cleaning, customers will be able to keep their equipment running cleanly, reliably, sustainably and satisfactorily for years."

"Our conclusion: The test of the comprex® unit can be rated as thoroughly positive. The cleaning effect can be seen as very good, in some cases even blockages could be loosened. Due to the rather simple operation, the unit could be operated without any problems after the short instruction. No problems were encountered during the test phase.

At this point, we would like to thank you again for the test opportunity and the trust you have placed in us."
