Interpretation of the values obtained:
• RSI < 6: boiler scale formation
• 6 < RSI < 7: neutral water
• RSI > 7: corrosive water
As a general rule, the RSI index should be between 5.6 and 7.5. If that is not the case,
contact a specialist.
5.
Free chlorine (Cl
2
)
Disinfecting with chlorine is
not done in closed systems, neither in energy recovery
systems
.
A continuous level of 0.5 ppm should not be exceeded. For shock treatments, a maximum
limit of 2 ppm for maximum 30 minutes/day applies.
6.
Chlorides (Cl
-
)
Chloride ions will create pitting corrosion on stainless steel. Their concentration should be
limited, depending from the RSI value.
RSI < 5.5
5.6 < RSI < 6.2
6.3 < RSI < 6.8
6.9 < RSI < 7.5
7.6 < RSI
