[Equest-users] Fuid-cooler has zero design flow

[Pasha Korber-Gonzalez]

You might not be able to link these items together (restriction of DOE-2),
you should look in the DOE-2 manuals (Volume 2) under heat rejection
equipment and see if this equipment piece will connect to a WLHP...sometime
there are little details that DOE-2 won't let happen exactly as you want it.

Hope this helps you a little.
