plate heat exchanger

phosgene

I have a plate heat exchanger in a weird set up.
it is from the 80s wondering what the temp rise and pressure drop should be?
This is actual hot water from the ground tied into several buildings around town.
pressure on return line and supply line

There is no real way to tell the temp rise or pressure drop because you don't know the original design. Call the manufacturer with the nameplate information......that's just a start

I will try that,Thanks
Thought there might be a general rule of thumb
