Comprex® cleaning process

The advantages at a glance

From test cleaning to your own comprex® plant

Just a few steps to a customized cleaning solution

With your own comprex® plant, you keep your line systems clean with "comprex® in place (CIP)" and ensure smooth production processes. Get an overview here of the steps we take to develop your own comprex® unit.


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.
