Figure 67 Environmental Conditions for Non-Condensing Operation
Water must not be allowed to condense on or in the optics. The dashed and solid lines in
Figure 67 cover the permitted cooling water temperatures for the PIPA-Q optical connector
and can be used to determine if the atmosphere is condensing. For example, if the ambient air
temperature is 25°C and the relative humidity is 40% then there will be no condensation for
any cooling water temperature in the specified range as the condition is below the 15°C
cooling water curve. However, if the ambient air temperature is 35°C and the relative humidity
is 80% then the cooling water temperature should be 35°C to prevent condensation.
