According to one aspect of the invention, a heat transfer system comprises a heat transfer fluid circulation loop. The heat transfer system includes a heat exchanger disposed in the heat transfer fluid circulation loop. The heat transfer fluid is an aqueous solution having a pH of 7.8 to 8.0 that comprises from 1.00 wt. % to 1.20 wt. % of a buffer composition comprising sodium and/or potassium salts of borate, carbonate, sodium bicarbonate, from 0.40 wt. % to 0.60 wt. % of a straight chain aliphatic dicarboxylic acid, from 0.90 wt. % to 1.10 wt. % of a branched aliphatic carboxylic acid, from 0.40 wt. % to 0.60 wt. % of an aromatic carboxylic acid, from 0.04 wt. % to 0.08 wt. % of a molybdate salt, and from 0.01 wt. % to 0.03 wt. % of an aldehyde biocide, based on the total weight of the heat transfer fluid.
