Legionella, pseudomonads or turbidity
We clean your pipes
and water-bearing systems
inside buildings
Welcome to comprex® Building
Clean pipes and water-bearing systems thanks to comprex®
We differentiate between functional (heating and extinguishing system) and hygienic (drinking water installation) water systems.
Deposits impair the functionality and performance of heating and extinguishing systems.
In drinking water installations, turbidity and contamination affect the quality of the drinking water.
With comprex® we create clean conditions in new and existing systems.
Functional water systems
Deposits can be corrosion products, limescale and dirt. They influence the flow and pressure in extinguishing systems and also the heat transfer in heating systems. The function of the fittings is no longer guaranteed.
comprex® removes these deposits and restores the function of your system.
Safe heating and fire extinguishing systems thanks to comprex®.
Drinking water installation
Deposits are the cause of turbidity and biofilms are responsible for microbial contamination. Both influence the quality of drinking water.
comprex® removes unwanted deposits and biofilms, including legionella and pseudomonads.
comprex® restores the perfect hygienic condition of cold water pipes, hot water pipes and circulation pipes.

The solution for contamination in water pipes
We help with comprex®
With comprex®, we have the solution for a wide range of contamination and cleaning requirements for water pipes inside buildings. Our customers confirm these successes in practice time and time again.
Read on our website how comprex® can restore the function of heating systems or fire extinguishing systems or, in the case of drinking water installations such as problems with legionella and turbidity, the hygienically perfect condition.
For new systems, the comprex® impulse flushing process helps to remove assembly-related auxiliary materials, foreign matter and impurities.
Functional water systems
Heating systems
Deposits in heating circuits and heating systems significantly reduce the flow rate and heat transfer. They cause considerable operating problems in the long term. With comprex® we provide a remedy.
- Hospitals & Clinics
- Underfloor heating
- Residential, Office & Commercial
- Hotels & Restaurants
- Heat exchanger
- Public buildings
Extinguishing systems
Functioning extinguishing systems are an essential part of fire protection.
Deposits can impair the function. With comprex® we create security.
- Water extinguishing systems
- Other types of extinguishing systems
- Sprinkler systems
- Water spray systems
- Water mist systems
- Foam extinguishing systems
Drinking water installation
Legionella
Legionella bacteria are ubiquitous in freshwater and can multiply in water-bearing systems. In the event of improper operation, for example due to deposits in the circulation pipe, increased concentrations can occur in drinking water installations. Then quick action is required. This is because legionella poses a serious health risk. The rod-shaped bacteria live in water and can cause the infectious disease legionellosis through droplet transmission.
- Hospitals & Clinics
- Kitas, Schools & Universities
- Senior centers & nursing homes
- Residential, Office & Commercial
- Hotels & Restaurants
- Swimming pools & gyms
- Public buildings
Pseudomonads
Microbiological contamination can occur in drinking water pipes. The causes are structural, operational or procedural deficiencies. Pseudomonads, especially Pseudomonas aeruginosa are rod-shaped bacteria. They can be dangerous for people with weakened immune systems. They are a dreaded hospital germ with antibiotic resistance. Therefore, quick action is required in the event of contamination.
- Hospitals & Clinics
- Kitas, Schools & Universities
- Senior centers & nursing homes
- Residential, Office & Commercial
- Hotels & Restaurants
- Swimming pools & gyms
- Public buildings
Turbidity
The cause of turbidity in drinking water installations is usually corrosion, especially in old steel pipes. This is usually noticeable by a reddish-brown discoloration of the drinking water. Corrosion products can clog filters, strainers, aerators or angle valves. In addition, the cross-section of old steel circulation pipes is decreasing. This reduces the flow rate.

- Kitas, Schools & Universities
- Senior centers & nursing homes
- Residential, Office & Commercial
- Hotels & Restaurants
- Swimming pools & gyms
- Public buildings
New installations
Before commissioning the drinking water system, the tightness and hygienic condition must be ensured. With COMPREX® we can thoroughly clean your drinking water system before putting it into operation.

What information you can have ready with your request
Good preparation
What kind of building
Background information, facts and figures about the building help us to understand the situation and provide you with targeted advice.
Number of taps
The number of taps gives us an initial estimate of the time required for comprex® cleaning of the drinking water system.
Pipeline material
The material of the drinking water system also plays an important role in the further procedure.
Place of sampling
This information helps to further isolate the cause of the problem and to initiate targeted measures.
A clean result in just a few steps
Our approach
01
Individual advice
Based on your inquiry, our hygiene experts first discuss the individual task with you and clarify the general conditions. In preparation for the site visit, we ask for building plans in preparation for the site visit.
02
On-site meeting and preliminary planning
The basis for a successful cleaning measure is sound preliminary planning. On site, we identify necessary conversion measures and discuss the implementation of the project with you.
03
Schedule and offer
Depending on your needs, we schedule cleaning on weekdays, weekends, during the day or at night. Based on the preliminary planning, our experts work out the detailed schedule and prepare an offer and for the cleaning measures.
04
Start cleaning
We come to you on schedule with our comprex® technology. We prepare your drinking water installation for cleaning and connect our technology. Based on the schedule, we clean your drinking water installation section by section – one after the other cold water, hot water as well as circulation water pipes.
05
Removal of microbial contamination
The comprex® unit generates controlled pulses with multi-filtered compressed air. Fed into the cleaning section, these pulses generate highly accelerated air and water blocks and enormous turbulence with strong shear and drag forces. These mobilize biofilms and deposits and reliably remove them.
With comprex® , we nevertheless clean gently and always remain below the permissible system pressure.
06
Bleeding the system
As soon as no more turbidity is visible at the sampling points, we deaerate the cleaned strand. The cleaning of this section is completed.
07
Optional: disinfection
At the customer’s request, we can also carry out chemical disinfection in accordance with DVGW W 557 after thorough cleaning of the pipeline. We use hydrogen peroxide or chlorine dioxide for this purpose.
08
Commissioning
After completion of the cleaning and, if necessary, disinfection measures, sampling must be carried out. Care must be taken to ensure that the water does not stagnate in the pipeline. As soon as the result of the sampling is available and faultless, the drinking water installation can be put back into operation.
