2.2.3 Water ow rate at the heat exchangers
It is necessary to ensure that the water ow rate during operation is no higher than 1.5 times and no lower than 0.5
times the nominal ow rate of the unit stated in the Technical Catalogue.
2.2.4 Water composition
Dissolved substances in the water can cause corrosion in the heat exchangers.
It is mandatory to make sure the parameters of the water comply with the following table:
Description Values
Total hardness
2,0 ÷ 6,0 °f
1.2 ÷ 3.4 °d
Langelier index - 0,4 ÷ 0,4
pH 7,5 ÷ 8,5
Electrical conductivity 10÷500 µS/cm
Organic elements -
Hydrogen carbonate (HCO3-) 70 ÷ 300 ppm
Sulphates (SO42-) < 50 ppm
Hydrogen carbonate / Sulphates (HCO3-/SO42-) > 1
Chlorides (Cl-) < 50 ppm
Nitrates (NO3-) < 50 ppm
Hydrogen sulphide (H2S) < 0,05 ppm
Ammonia (NH3) < 0,05 ppm
Sulphites (SO3), free chlorine (Cl2) < 1 ppm
Carbon dioxide (CO2) < 5 ppm
Metal cations < 0,2 ppm
Manganese ions (Mn++) < 0,2 ppm
Iron ions (Fe2+, Fe3+) < 0,2 ppm
Iron + Manganese < 0,4 ppm
Phosphates (PO43-) < 2 ppm
Oxygen < 0,1 ppm
ppm = mg/l
The use of water with values above the limits stated in the table will immediately void the warranty.
It is mandatory to include a system for eliminating possible organic substances in the water that could pass through
the lter and settle in the heat exchangers, which would lead to malfunctioning and/or breakage over time.
The use of water containing organic substances will immediately void the warranty.
