Abstract
The present invention relates to an aqueous glycol-free heat transfer fluid comprising sebacic acid, benzotriazole, morpholine, and at least one of sodium nitrite and sodium molybdate dihydrate, wherein a sum of concentrations of sodium molybdate dihydrate, sebacic acid, benzotriazole, morpholine, sodium nitrite is equal to or less than 1% (w/w). Preferably, the sum of concentrations of sodium molybdate dihydrate, sodium nitrite, sebacic acid, benzotriazole and morpholine is less than 0.65% (w/w). Preferably, the respective concentration is: 0-0.134% (w/w) sodium molybdate dihydrate; 0-0.028% (w/w) sebacic acid; 0-0.028% (w/w) benzotriazole; 0.08-0.812% (w/w) morpholine and 0-0.134% (w/w) sodium nitrite.
