CV-PASSIVATOR is a specially blended Passivator and Neutralizer, absolutely safe for after treatment of descaled metal parts. Descaled metal surfaces are sensitive to corrosion from the oxygen in the air and water must therefore be given an anticorrosive finish during the cleaning process as a form of passivation. In addition, left-over descaling chemicals on the metal surfaces or inside the systems may cause corrosion, especially so where mere flushing of fresh water may not remove entirely all the descaling chemicals.


It is thus important to neutralize the entire system after a descaling job.  



Product Benefits:

  •  Protect entire system against corrosion. This prevents equipment failure due to condensate corrosion. It protects the complete system by dosing chemical at a single point.

  •  CV-Passivator reduce corrosion and formation of iron bearing deposits. This helps in keeping heat exchange surfaces, steam traps e.t.c. clean thereby improving heat transfer efficiency.

  •  CV-Passivator forms protective layer on the surface of the metal and ensure complete removal of acid traces.



Usage Procedure :


  • After every descaling process, add in appropriate amount  of CV-Passivator into the system and run circulation for at least half an hour.

  • To determine the amount to be used , add in CV-Passivator until the pH of the cleaning solution reached 6.5 to 7.0.
  • After treatment for half an hour , drain and flush circulating systems thoroughly until the water is clear.
  • Check the pH of the fresh circulating  water to ensure it’s the same pH as in coming water of pH 7+  0.5
