Thank you for all of your insight. Glycol supply and return headers are located near the chilled water user. That was the only reason why I thought I could use glycol. THe 65F is the maximum temp our process needs, 45-50 is preferable.
I need to cool down city water from 90F to 65F. I have glycol available at the plant.
Any idea on how to size the plate exchanger?
Thanks for your help.
