Q: The Industry seems to be moving away from nitrites – What is the nitrite content in FINAL CHARGE GLOBAL Coolant/Antifreeze?
A: Nitrites have long been used in fully formulated coolants, or incorporated in Supplemental Coolant Additive (SCA) then mixed with conventional coolants, for their ability to protect wet sleeve liners against cavitation and corrosion. However, nitrites in conventional and fully formulated coolants deplete, thereby reducing the level of protection provided. Also, ongoing testing and monitoring of nitrite levels are required to ensure the proper levels are maintained. To extend coolant service life and reduce maintenance time and cost associated with testing and maintaining inhibitor levels, the heavy-duty industry is moving toward nitrite-free Organic Acid Technology (OAT) coolants. With OAT coolants, conventional inhibitors, like nitrites, are replaced with organic corrosion inhibitors that deplete very slowly over time. As a result, extended life corrosion and cavitation protection is achieved without a regular schedule of liquid additives; inhibitor testing and maintenance coolant filters. FINAL CHARGE Coolant/Antifreeze is formulated with a patented nitrite-free formula.
