CIP cleaning:
Shorter cycles. Less water. Same quality.
Comprex® optimizes the water rinse cycles in industrial CIP processes using targeted air-water pulses (or other rinsing media). This shortens cleaning cycles, significantly reduces water and media consumption and maintains consistently high cleaning quality.
Reduced use of media - depending on the application
Integration into existing CIP systems possible
CIP often costs more than necessary
In food and beverage production, hygienic safety is non-negotiable. At the same time, manufacturers of consumer goods and personal care products face similar challenges: Traditional CIP cleaning processes consume large amounts of water, cleaning media and energy and lead to long downtimes, which have a direct impact on productivity.
The result: with rising operating and ancillary costs, productivity is becoming a decisive competitive factor for production sites.
Every hour of cleaning downtime means lost production. Conventional CIP processes often require extended water rinse cycles – not because they have to be, but because more efficient alternatives were not previously available.
Caustic, acid, disinfectants and rinsing water – their use leads to considerable purchasing and disposal costs.
ESG reporting, water charges, disposal costs. Water-saving measures are increasingly becoming mandatory for industrial companies.
Energy, water, chemicals, disposal – the operating costs per CIP cycle are rising. At the same time, there is growing pressure to measurably improve and document resource efficiency.
Pulses optimize the water rinse cycle in the CIP process
The patented Comprex® process uses targeted air-water pulses to mechanically remove product residues from industrial piping and production systems.
The water rinse cycles in the CIP process thus become significantly more efficient – the media requirement is reduced because the chemicals come into contact with a more thoroughly pre-cleaned surface and the use of chemicals in the CIP process can therefore be measurably reduced.
Integration into your CIP system
The stationary Comprex® unit is integrated directly into the existing CIP circuit and can be easily integrated into any standard control infrastructure – whether Siemens, Allen-Bradley or others. The conversion effort is minimal: usually connections and individual bypasses if necessary.
Pulses instead of flushing
Targeted air-water impulses mechanically remove product residues – faster and more thoroughly than conventional water rinsing.
Chemicals work more efficiently
Mechanical cleaning removes product residues more thoroughly than conventional water rinsing. The chemical phase thus meets a better pre-cleaned surface – lower chemical concentration and shorter exposure time lead to the same result.
Proof according to your standard
The cleaning result is visible and can be measured. Validation is carried out in accordance with your company’s internal procedures and requirements – we provide the basis for this.
Shorter CIP cleaning times. Lower costs. Same quality

Many systems – one optimized cleaning process
Whether food and beverage production, consumer goods or the pharmaceutical industry: wherever product lines and process systems need to be cleaned regularly, the Comprex® process can make CIP processes more efficient.
"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 CIP cleaning
What does CIP cleaning mean?
CIP (clean-in-place) cleaning is an automated cleaning process for industrial production facilities, piping systems and process engineering components, in which cleaning takes place without disassembly. Defined cleaning media are fed through the closed system to remove product residues, biofilm and deposits.
Areas of application for CIP cleaning: Food, beverage, pharmaceutical, chemical and consumer goods industries. The aim is to ensure reproducible cleaning results with minimum production downtime.
What are the advantages of CIP cleaning with Comprex®?
Compared to conventional CIP processes, Comprex® replaces parts of the water rinse cycle with targeted air-water pulses. This shortens cleaning times, reduces water consumption in the CIP process and reduces the use of chemicals.
At the same time, the cleaning quality is demonstrably maintained. In many applications, operating costs per CIP cycle can be measurably reduced.
How can water consumption in the CIP process be reduced?
Water consumption in the CIP process can be reduced by optimizing the water rinse cycle, shortening rinsing times and more efficient mechanical pre-cleaning. Technologies such as air-water pulses enable more thorough removal of product residues, so that less rinsing volume is required.
How can the cleaning time in CIP systems be reduced?
The CIP cleaning time is reduced if product residues are mechanically dissolved more quickly and the subsequent chemical phase is more efficient. Optimized process control reduces downtimes and increases production availability.
How high are the operating costs of a CIP process?
The operating costs of a CIP process are made up of water, energy for heating, chemicals, disposal and production downtime. In many companies, these costs represent a significant proportion of the ongoing production costs.
For which systems is CIP cleaning suitable?
CIP cleaning is suitable for production plants, process lines, piping systems, heat exchangers, cooling and temperature control circuits as well as tanks and process engineering components.
Areas of application for CIP cleaning: Food, beverage, pharmaceutical and chemical industries. CIP is used here to reliably remove product residues and biofilm – even in complex geometries or areas that are difficult to access.
Can an existing CIP system be retrofitted?
Yes, modern optimization solutions can be integrated into existing CIP systems. Retrofitting is typically carried out by integrating them into the existing CIP circuit and the existing control infrastructure.
Can a CIP process also use rinsing media other than water?
Yes, the Comprex® process can be used in the CIP process not only with water, but also with other rinsing media. Media with higher viscosity (up to 100 cSt) can also be used as rinsing media.
You can find out more about applications with viscous media here: → Solutions for viscous media
If the medium used can cause potentially explosive atmospheres (hazardous area), the process can also be operated with inert gases instead of compressed air.
How is the effectiveness of cleaning proven?
The cleaning effect is verified by measured values, documentation and comparison with the initial situation (baseline). Typical parameters are conductivity, pH value, microbiological tests or product-specific residue analysis.
Validation is carried out in accordance with the internal hygiene, quality and process requirements of the respective company and can be integrated into existing documentation systems.
