I'm new to water treatment so when I was asked to treat the loop with a corrosion inhibitor of course I have to "do it right". When I asked my boss how do I know when the right ratio he said they had always just poured it in until it looked dark. I convinced him to "let's do it right" and ordered a nitrate test kit which told you how to test but did not give any levels. Now to the questions.
If any of you have worked with treatment please help answer this for me.
What is the industry standard for cooling closed loop systems in PPM?
At what point is it to weak or to strong?
How often should you flush entire system and treat?
