Abstract: Heat carrier liquid concentrate contains (wt.%), in addition to glycol(s), (a) 0.05-10% aliphatic amine(s) (I), (b) 0.005-3% optionally stabilized silicate(s), (c) 0-3% corrosion inhibitor(s) selected from hydrocarbyl-triazoles and -thiazoles, (d) 0-5% alkali metal or (substituted) ammonium molybdate(s) and (e) 0-1 polymeric hard water stabilizer(s). Heat carrier liquid concentrate contains (wt.%), in addition to glycol(s): (a) 0.05-10 (preferably 0.1-5)% aliphatic amine(s) of formula (I); (b) 0.005-3 (0.01-1)% optionally stabilized silicate(s); (c) 0-3 (0.01-3)% corrosion inhibitor(s) selected from hydrocarbyl-triazoles and -thiazoles; (d) 0-5 (0.01-1)% alkali metal or (substituted) ammonium molybdate(s); and (e) 0-1 (0.1-0.5) polymeric hard water stabilizer(s): NR1R2R3 (I) R1-3 = H or optionally branched 1-9 C (preferably 3-4C) (hydroxy)alkyl. An Independent claim is also included for a ready-prepared aqueous heat carrier liquid containing water and 10-90 wt.% of the concentrate.
