After the first maintenance of the new unit, does the heat exchanger in the circulating water system need to have its oxide film treatment done again?
A company I worked for before did not carry out such handling. I’m not sure about other companies; they probably don’t use it
It is done in accordance with the specifications, but the quality of the work depends on the manufacturer. If the unit doesn’t have enough funds, it’s advisable not to proceed; during the initial stage of operation, simply increase the dose of the slow-release scale inhibitor and maintain a higher pH level. If the iron ion concentration doesn’t rise after one week of operation, then there will be no problem
