Typical challenges - and how we solve them
Production systems must work reliably at all times – from the product line to the demineralized water line. With Comprex® you can clean your systems efficiently, without chemicals and without stopping production – for permanently high process reliability.
The problem
Product residues and biofilms can build up in product lines during operation. They reduce product quality and impair process stability.
In process water, demineralized water and pipelines, deposits and a reduced pipe cross-section lead to efficiency losses and increased energy requirements.
In the long term, such deposits can lead to production interruptions and avoidable downtimes.
The solution
With the Comprex® process, production systems are cleaned effectively and gently – completely without chemicals. Dynamic air-water pulses remove deposits and biofilms in a short time, often without dismantling or interrupting production. This keeps your production efficient, safe and stable.
Typical areas of application:
- 
Product lines
 - 
Production facilities
 - 
Process water pipes
 - 
VE water pipes
 - 
Pipelines
 
The result
After cleaning, your systems return to full performance: product quality and energy efficiency increase, operating costs decrease. Comprex® helps to maintain operational hygiene.
Regular cleaning keeps your systems stable and ensures consistent production reliability as well as economical, resource-saving operation – with clean lines and optimum conditions for smooth production.

3 steps to clean production systems
Step 1 Analysis & planning
Together with you, we check the structure and condition of your piping systems and production facilities. On this basis, we develop a customized cleaning plan – tailored to your system technology, critical bottlenecks and the required process reliability.
Step 2 Preparation
We plan the cleaning sections, determine the feed-in and feed-out points and take care of all the logistics so that your production can continue to run as smoothly as possible. Our team of technicians will come to you with the appropriate equipment and remain on site for the duration of the project.
Details on our mobile cleaning systems and self-sufficient trailers for different nominal widths can be found here. We are also happy to implement permanently integrated solutions with you.
Step 3 Cleaning & commissioning
Cleaning is carried out using targeted air-water impulses from the Comprex® process. Deposits and residues are thoroughly removed – quickly, gently and without chemical additives.
Once the measure has been completed, we check the result and return the system to regular operation.
Fast, professional and ready for use: Our experienced team will take care of the cleaning for you – whether as a one-off or regularly as part of your maintenance concept.
Would you like to use the Comprex® process yourself? No problem. Our mobile systems are available for hire – including instruction, accessories and technical support.
Would you like to permanently integrate your own Comprex® cleaning system into your operating processes? Whether mobile or stationary – we have the right system for you and will train your staff.
"I wouldn't have believed it if I hadn't seen it myself at the Landau test center. In detailed trials cleaning our products in test pipelines, we reached up to 60% savings in cleaning time and up to 90% in water consumption."
"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."
"Before flushing the main pumping station, we had a pump runtime of almost 20 hours and a pumping capacity of 250 m³ of wastewater. As a result of the flushing action, we were able to determine that on some days we achieve a pumping capacity of 270 m³ of wastewater with a pump runtime of 15 hours. This clearly shows an improvement in the efficiency of our system.
"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 Hammann company was commissioned to clean the stainless steel gas pipe using their Comprex process. Success was already evident when the cleaning was carried out, as the escaping rinse water was heavily contaminated.
After cleaning and recommissioning, the aforementioned pressure fluctuations did not occur again. It was not easy to create the necessary inlet and outlet to the gas pipeline. It is also problematic to take a gas pipeline out of service for a longer period of time when there is no redundancy. Nevertheless, the effort was worth it, as the cleaning has had the desired effect."   
"Our initial skepticism that comprex could be too intense for our piping system was unfounded. The pulse pressure always remains below the network pressure and so we don't have to worry about pipe bursts due to excessive pressure. The pulse flushing process can reduce the deposits in our old network so significantly that maintenance is absolutely economically viable compared to replacement."
"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."
											"We have had very good experiences with comprex and are very satisfied with the cooperation that has grown over the years. The Hammann GmbH technicians know our network, arrangements are quick and uncomplicated and the assignments are already a fixed part of our annual planning for network maintenance."

Frequently asked questions about production systems
					 How does cleaning with Comprex® work in production systems? 
							
			
			
		
						
				The patented Comprex® process uses controlled pulses of air and water that move through the system at high speed. This creates shear forces that reliably loosen and remove deposits and residues – without any chemical additives and without completely shutting down the system.
					 Does production have to be interrupted for cleaning? 
							
			
			
		
						
				In many cases, we can plan the cleaning so that only individual parts of the system are taken out of operation for a short time. The rest of production continues, minimizing downtime
					 Which residues can be removed? 
							
			
			
		
						
				The Comprex® process reliably removes product residues, biofilms, limescale, rust, sludge and other mineral and particulate deposits from product, process and demineralized water pipes. All residues are completely and gently removed – without chemicals and without polluting the systems.
					 Is the cleaning process suitable for all system materials? 
							
			
			
		
						
				Yes, Comprex® technology is gentle on materials and can be used for steel, stainless steel, copper or plastic pipes – even in sensitive or older systems.
					 How long does cleaning take? 
							
			
			
		
						
				The duration depends on the size and complexity of the system and the degree of soiling. Many cleanings are completed within a few hours – with minimal effort for preparation and recommissioning.
					 What advantages do I have after cleaning? 
							
			
			
		
						
				After cleaning, the flow rate improves, energy efficiency increases and process reliability is enhanced. Regular cleaning ensures permanently stable processes and reduces maintenance costs.
					 How often should cleaning be carried out? 
							
			
			
		
						
				This depends on the product, operating mode and process water quality. In many companies, regular use – about once a year or when changing products – has proven effective in preventing deposits at an early stage.
