Water hardness
Water hardness is defined by the amount of hardeners (carbonates and bicarbonates) in the water. Particularly at higher temperatures, the hardeners accumulate to the surface of the water cooling cartridge and lead to a reduction in performance. In case of very hard water, these deposits must be taken into account when designing the water cooling cartridge.
The following table shows the classification of German degrees of hardness to water quality °dH:
Degree of hardness10 mg/l of hardener corresponds to 1 °dH | Water quality |
|---|---|
0 – 5 °dH | Very soft water |
5 – 10 °dH | Soft water |
10 – 20 °dH | Medium hard water |
20 – 30 °dH | Hard water |
> 30 °dH | Very hard water |
