The solution to the problem of contamination and corrosion in chillers with water-bearing cooling systems

Simply pour in and forget about it!

Process chillers and water-bearing systems have strict requirements to fulfil and are permanently in use in most cases. Their unrestricted availability is a fundamental requirement for efficient operating sequences and production processes. All the more serious are the consequences if the cooling systems no longer function as they should.

Causes of production errors

3D printers and industrial procedures in the plastics and metal processing industry require precise, constant cooling of production systems. Disruptions have a direct impact on the product.

Maintenance efforts

Process chillers and cooling circuits must be serviced regularly to avoid system downtimes. This takes up a lot of time and is associated with high ongoing costs.

System downtimes

Unfortunately, cooling lines are often inaccessible. It’s just a matter of time before this leads to limescale formations, algae build-up and blockages of the system.

Find out about the causes of contamination and corrosion now. And why our robust CoolFlux 42 process cooling medium is the perfect solution to the problems chillers face and how you can protect your water-bearing process circuits against contaminants and corrosion.

The causes

Contamination and corrosion can have serious consequences. Malfunctions and system downtimes due to corrosion and contamination can occur if the system water quality is not optimally adapted to the process cooling.

Biological loads

Fluctuations in the glycol concentration or the pH value as well as a continuous inflow of dust and oxygen in semi-open chillers lead to favourable living conditions for bacteria and algae. The resulting biology can clog up the cooling channels, heat exchangers or pipes and water filters.

Risk of corrosion

Coolant contact with different metals encourages the exchange of ions - from high quality to lower quality materials. This causes deposits or corrosion, e.g. in the capillaries or cooling channels. The use of demineralised water (distilled water) or pure tap water actively supports corrosion.

The solution

Coolflux 42 - the process-stable long-term fluid for 3D printing and industrial applications such as injection moulding and metal processing.

Coolflux 42 is an innovative process cooling fluid to meet the highest of demands. Biological loads are a thing of the past thanks to its constant mixing ratio. Simply forget about containments on the interior pipe walls, biological smear films, bacterial growth and algae formation, limescale build-up and corrosion, clogged nozzles and valves, pressure losses due to cross-section constrictions, reduction of heat transfer, and so on and so forth ...

Easy to use, extensive protection

Coolflux 42 is a complete cooling fluid and replaces the coolant as a whole. It doesn't have to be mixed or added on-site. Once introduced into the previously cleaned cooling circuit, it sustainably protects against contamination and ensures long-term stability of the system without the need for any service expenditure. Cost-saving and effective.

for indoor use

It’s that easy…

Step 1


The system must be perfectly clean for the flawless functioning of our cooling fluid. Our analyses keeps us one step ahead of problems in the cooling process, laying the foundation for application-specific solutions for the individual cleaning / renovation of your cooling system.

Assessment of the cooling fluid used

  • Appearance
  • Colour
  • Cloudiness, sediment
  • pH value
  • Density
  • Acid capacity

Assessment of the corrosion processes

  • Iron
  • Copper
  • Zinc
  • Aluminium


  • Test for colony-forming units
Step 2


System clean-up is a complex undertaking that requires expertise and plenty of experience. Manual, mechanical cleaning of chillers and cooling circuits, as is the case in many places, is not only costly, but is also rarely successful over the long term because system components are often only partially accessible.

Professional help with contamination

Only intensive chemical cleaning with alkalis, acids and neutralisers tailored to the specific application will generate really clean chillers and thus the basis for use of Coolflux.

Step 3

Filling Coolflux

Coolflux forms a protective film and sustainably protects against corrosion and algae build-up. Due to its constant mixing ratio, the risk of biological pollution is reduced to a minimum. It has also passed several tests for all common cooling system materials.
