Determining the cooling water mixture for 10° dGH
Example:
Cooling system capacity: 2300 l
Hardness of available fresh water: 19° dGH
To determine the fresh water mixture, proceed from the abscissa “Cooling system capacity” (2300 l)
via the intersection of the 19° dGH line to the ordinate “Amount used” and read off the amount of
water with 19° dGH which is to be used and which is to be mixed with the difference of 2300 - 1200 =
1100 litres of condensate or fully de-ionized water.
