Long-life cooling fluid for industry and 3D printing
Clean cooling circuits. No breakdowns. No constant maintenance.
Coolflux 42 permanently protects water-bearing cooling systems against biofilm, scale and corrosion – for 3D printing, injection moulding and metal processing.
Clean. Fill. Forget.
- Free of SVHC substances
- Not on the REACH candidate list
- For steel, copper, zinc and aluminium
- Ready to use in 25 kg containers
Contaminated cooling water costs more than you think.
Process chillers usually run around the clock. When cooling doesn't work properly, the whole production line feels it.
Production errors
Fluctuating cooling performance causes rejects and quality problems – often without the cause being spotted right away.
Maintenance effort
Flushing, topping up, changing filters: regular servicing ties up time, staff and budget.
System downtime
Algae, scale and corrosion clog pipes, nozzles and heat exchangers – until the system comes to a standstill.
Where the problems come from
Biological load
Fluctuating glycol concentration or pH, dust and oxygen entering semi-open systems create ideal conditions for bacteria and algae. The resulting biofilm clogs cooling channels, heat exchangers and filters.
Corrosion
When the cooling water comes into contact with different metals, deposits and corrosion form – for example in capillaries and cooling channels. Plain tap water or distilled water even speeds this process up.
The solution
Coolflux 42 protects your system – for the long term.
Coolflux 42 is a ready-to-use, process-stable long-life cooling fluid. It completely replaces your current coolant, forms a protective film in the circuit and keeps the system clean – instead of you having to clean it again and again.
Minimises biological load
Thanks to its constant mixing ratio, bacteria and algae find no breeding ground.
Prevents scale and corrosion
Protects pipes, heat exchangers and tools.
Stable pH value
Constant conditions in the circuit, without re-dosing.
Ready to use
No mixing on site, no handling of chemicals or biocides.
Built for demanding processes
3D printing
Constant cooling for reproducible part quality – without downtime caused by clogged cooling channels.
Injection moulding
Mould temperature control and chillers: clean cooling channels, stable cycle times.
Metal processing
Protection against corrosion – even in circuits with different metals.

Switching over
Clean. Fill. Forget.
Clean
Drain the old coolant, then clean and flush the system thoroughly.
Fill
Fill in Coolflux 42 ready to use – no mixing, no additives.
Forget
Your cooling circuit stays protected – instead of constant fixing.
Is your system heavily contaminated?
Then have it cleaned thoroughly by a specialist company of your choice before switching over. Coolflux 42 then keeps it clean.
The ideal time: with new systems, when changing coolant or right after maintenance.
Typical signs:
- Cloudy or discoloured water
- Slimy deposits, algae
- Clogged nozzles or filters
- Falling cooling performance
Frequently asked questions
How long does Coolflux 42 last in the system?
Coolflux 42 is designed as a long-life fluid and stays in the circuit. How long depends on the system and its operation – feel free to ask us about your application.
Do I have to clean my system first?
Yes. Coolflux 42 keeps a clean system clean for the long term. If the system is heavily contaminated, we recommend having it cleaned by a specialist company.
Which materials is it compatible with?
Coolflux 42 has been matched to the common materials in cooling systems, including steel, copper, zinc and aluminium.
Do I need to mix or dilute Coolflux 42?
No. Coolflux 42 is ready to use and completely replaces your current coolant. It is neither mixed nor added to an existing coolant.
Which container sizes are available?
Coolflux 42 is supplied in 25 kg containers.
