Demineralised water

For applications where the use of pure, good quality water is important.

Demineralised water

Tap water usually contains small amounts of salt. Demineralised water, also called demiwater, is technically pure water that has all salts removed. This makes the water suitable for numerous applications where the use of pure, good quality water is important, for instance the chemical and foodstuffs industries.
Demineralised water can for example be used as rinse water, boiler water, cooling water, test water or battery water.

The conductivity of water is measured using the unit micro Siemens per centimetre. This is represented by the symbol μS/cm. The conductivity of drinking water is between 300 and 700 μS/cm. This depends on the area in which the water is extracted.

The conductivity depends on the amount of minerals and salts dissolved in the water. Demineralised water has a low conductivity. It is produced with a conductivity of 0.1 – 1.0 μS/cm.


Demineralised water is available in the following packaging sizes:

  • 5, 10, 20 and 25 litre jerrycan
  • 200 litre drum
  • 1000 litre IBC
  • tank truck

Upon request, we can supply the demineralised water in a packaging of your choice, with, for example, your own labels.
