For series heat exchangers, why can’t the cores be removed together? Two floating-head heat exchangers, connected in series, placed one above the other. During the core extraction process for maintenance, why can’t two cores be extracted at the same time? Is it said that we have to wait until the first one is used up, the cleaning is completed, and it’s reinstalled before we can remove the second one? What is the basis for these requirements? What’s there to be afraid of?
Is that claim still around? This will cause mutual contamination. :lol
I lack experience and am afraid of making mistakes. ;P
If doing this has no impact, then let’s go with it.
It’s fine to pump simultaneously, but installation at the same time is not possible; if installation isn’t done simultaneously, there’s a greater likelihood that the inside of the shell side of the heat exchanger will become contaminated. One unit is repaired after another, which facilitates isolation and management. It’s a bit unreliable to worry about it getting crushed; it’s fine even when filled with a medium, let alone when it’s just an empty shell.
After pulling out both of them, is there enough space underneath the frame to place them?
There is limited space and manpower, so it has to be processed one by one
