Recommended adiabatic pre-cooler water flow rates
If any of the following happens:
•
at ambient conditions exceeding the given maximum ambient conditions,
•
with supply water quality data exceeding one or more of the concentration limits of above table "Minimum
supply water quality",
•
if the supply water has a Practical Scaling Index below 5.5,
Then:
•
the water flow needs to be increased to higher levels to avoid rapid fouling and scaling of the pre-cooler
medium. Contact your local BAC-Balticare representative for support.
