Developed and patented

Comprex® cleaning process

Our comprex® impulse rinsing process works entirely without chemicals, instead using only air and water according to a principle of physics. We inject filtered air into the section to be cleaned – in a controlled and pulsed manner. This creates packets of air and water blocks that flow through the section at high velocity.

They generate enormous turbulence with strong shear and drag forces, whereby they manage to mobilize and reliably discharge existing deposits. The result: clean pipes and clean water – efficient, gentle and economical.

Areas of application

– Industrial piping systems up to DN 65


Preplanning & Engineering

Each application requires careful pre-planning. We always take into account the local conditions and effortlessly adapt our comprex® process to the requirements of the equipment and systems in your plant.

During the pre-planning stage, we determine the cleaning sections with feed-in and feed-out points, plan the cleaning sequence and record the general conditions for the design of the comprex® cleaning system.


Test cleaning

We would be happy to carry out a test cleaning with our cleaning technology at your site so that you can personally convince yourself of the comprex® cleaning potential.


Concrete offer

Subsequently, we develop concrete proposals for the implementation of comprex® technology in your company.

Based on intensive preliminary planning, we will submit the offer that is right for you and the requirements of your production. We also advise you on the possibilities of software integration into your operations.


Customized plant

After test cleaning and planning, we know your requirements and adapt hardware and software to the structural conditions of your operation as well as to the desired cleaning intervals.

We manufacture your own comprex® system according to your cleaning requirements. Whether mobile or stationary - our developers and designers plan and build the cleaning unit exactly to your specifications.


Commissioning on site

The first step is the installation of your new comprex® system in your plant. During commissioning, we create suitable cleaning programs for your application. Your "comprex® in place (CIP)" is now ready for use.


Staff training

In the second step, our service staff will train your personnel so that you will be able to operate the comprex® Unit software independently at any time.

The preset cleaning programs and the intuitive touchscreen operation facilitate the handling of the cleaning measures and the setting of the necessary cleaning parameters.


After Sales Service

Even after integration of the cleaning unit at your site, we are available to advise you.

Whether maintenance, software updates, purchase of spare parts or further training - we are at your disposal according to your needs.
