Ready-to-use heat transfer fluids and methods for preventing corrosion in heat transfer systems are described.
Abstract: Corrosion inhibitor formulations for use in heat transfer fluids include: (a) an optionally substituted benzoic acid or a salt thereof; (b) at least a first n-alkyl monocarboxylic acid or a salt thereof and a second n-alkyl monocarboxylic acid or a salt thereof, the first n-alkyl monocarboxylic acid and the second n-alkyl monocarboxylic acid being different; and (c) an azole compound. A ratio of weight percent of the first n-alkyl monocarboxylic acid or the salt thereof to weight percent of the second n-alkyl monocarboxylic acid or the salt thereof ranges from about 1:0.75 to about 1:2.00. A ratio of weight percent of the benzoic acid or the salt thereof to combined weight percent of the first n-alkyl monocarboxylic acid or the salt thereof and the second n-alkyl monocarboxylic acid or the salt thereof ranges from about 1:0.30 to about 1:2.25.
Abstract: A super concentrate additive solution is disclosed herein. A super concentrate additive solution can be added into a heat transfer fluid to improve corrosion protection performance and to extend the service life of a heat transfer system or the fluids therein. A method includes adding a super concentrate additive solution to a heat transfer fluid to form a super additive heat transfer fluid and adding the mixture to a heat transfer system. A super concentrate additive solution can also be used in flexible production of a high corrosion protection performance heat transfer fluid concentrate, pre-diluted heat transfer fluids, or ready-for-use heat transfer fluids.
