If the total iron level increases, does that indicate corrosion in the pipes? The circulation system generally doesn’t see an arbitrary increase in iron powder levels; either there’s a problem with the system itself or it’s due to something introduced recently. It also depends on what kind of circulation system it is – whether it’s an open-type system – and whether there might be any iron powder or similar substances nearby that could end up in the system. I don’t really understand either; I’m just talking nonsense
When adding a large number of new devices to a circulating water system or putting them into use, it is necessary to carry out cleaning and film-forming treatment on the system once again in order to better ensure that the water quality meets the required standards.
When storing and welding the materials of new equipment, iron ions may be generated; therefore, it is necessary to follow the suggestions given on the 3rd floor. The above opinions are provided for discussion.
There are acidic substances such as hydrogen sulfide and sulfuric acid, resulting in a low pH value
Check if there’s any issue with the pipes; generally, heat exchangers are made of stainless steel, so it’s unlikely that the problem lies there!
I think it’s the problem with the new heat exchanger; there must be some rust or similar on the walls of the new equipment, and that’s causing issues in the circulating water. If nothing goes wrong, it should be fixed in about a week.

I agree with the opinion above; after the new heat exchanger is integrated, it’s best to carry out a full-system cleaning and film-forming process.
The new device should be pre-coated before use
Has the newly installed heat exchanger been cleaned? New equipment will definitely have a lot of rust and the like when stored. (It’s just my personal opinion, a guess And that's it ):lol
