(1)
Chemical treatment can be considered (if compliant with local regulations) when tap water exceeds
limit values or when usage of tap water is preferred with more than 1500 cooling hours per year.
(2)
Factory setting.
(3)
Use tap water bypass when the conductivity does not meet this threshold value or dose a corrosion
inhibitor to prevent corrosion (if compliant with local regulations).
(4)
Change IntrCooll® water conductivity limit setting to this value when using reverse osmosis water.
3.11.1.1
RSI value
Measuring water hardness is inaccurate to predict forming of scale. Forming of
scale is depending on different physical quantities like pH-value, conductivity,
temperature, calcium concentration and alkalinity and can be calculated with the
Ryznar Stability Index or RSI. The RSI value must be higher than 6 to prevent
issues due to scale. Please contact Oxycom if you have any question concerning
your water quality.
3.11.1.2
Conductivity
To remove the increased mineral concentration caused by the water evaporation
process, the IntrCooll® has a built-in sensor that continuously measures the
conductivity of the supply water. When the upper limit (factory setting) is
reached, the entire water content in the tank is drained and replaced with clean
supply water.
3.11.1.3
Oxycom Water Quality Calculator
Please contact Oxycom to be sure the supply water meets the supply water
requirements on page 29.
Use the Oxycom Water Quality Calculator to:
-
Check if the initial water quality (tap, RO) meets all requirements to prevent
scale forming and metal corrosion.
-
Calculate the amount of recirculation cycles after which the water quality has
changed in such way that one of the properties is about to exceed the limit.
-
When in some cases the supply water requirements cannot fully be met:
Analyze the supply water quality to determine the adjustment of the
conductivity setting on page 61 suitable for local circumstances. The
settings must be matched with an available local water quality report.
Caution
For a proper operation and low running costs regular maintenance and cleaning
is essential, refer to the maintenance document for more information. To keep
warranty the specified maintenance is mandatory.
Note
For more technical specifications about the mains water supply, refer to the
Specifications sheets on page 67.
