Ion exchanger cartridges

Easy to use, reliable and environmentally friendly in their function, these devices produce demineralised water by means of ion exchange. The scope of supply usually includes a conductivity meter, a hose connection set with quick-release couplings in the appropriate size and a filter cartridge.
In order to be able to call up optimum performance parameters from our new generation of metalworking fluids, such as increased tool life, reduced tool and seal wear, cleanliness and freedom from limescale of the machining unit and the interior surfaces of the machine tool, clear visibility through its viewing window and prevention of corrosion due to salts in the raw water, it is absolutely essential that the make-up water is fully desalinated.
The dpi coolant solutions do not need to be post-treated to prevent foaming. They could also work without raw water treatment, but then they would by far not reach the maximum performance parameters as with desalinated water. Some corrosion phenomena caused by desalination (chlorides, fluorides, sulphates, phosphates, calcium, etc.) during the life of the solution and increased conductivity cannot be prevented without full desalination.
We will be happy to name high-performance suppliers of such systems in your area on request.
