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 25 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 an increase in 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

Our world novelty

comprex® ToolClean

comprex® ToolClean cleans the cooling and temperature control circuits of molds. Purely mechanical – with air and water. Mobile, stationary and system-oriented use is possible and ensures consistent product quality and cycle times. Temperature control circuits remain clean and deposits are prevented.

K 2022

comprex® Impulse

comprex® removes deposits through targeted control of compressed air and water


Elbows & Fittings

comprex® impulses adapt flexibly to changes in the direction of the pipeline


Variable nominal widths

comprex® is suitable for pipe diameters between 1 mm and 1,200 mm


Nominal width change

In contrast to pigging processes, the comprex® pulses flow easily through
Cross-section changes in the piping system – without getting stuck



Comprex Impulse also clean across multiple levels with consistent effectiveness.


Branched systems

The entire piping system is cleaned section by section with comprex



The comprex® impulses easily flow through existing fittings in the system
and also clean dead spaces – where other processes cannot reach


We comprex your lines!

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 – the 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 rinsing section to be cleaned. From there, filtered compressed air is introduced into the line in a controlled and pulsed manner. Inside the pipe – with the water remaining there – packets of air and water blocks are created, which flow through the pipe 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 flushing
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 flushing. Cleaning is nevertheless gentle on the pipelines, as the pressure remains below the system pressure.
