ABSTRACT:
A heat transfer promoter composition comprises a triazine-dithiol derivative represented by the general formula ##STR1## wherein R represents --NHR' or --NR'.sub.2 wherein: R' is a hydrocarbon group; M is selected from the group consisting of hydrogen, alkali metals, and alkaline earth metals; and at least one of M groups is alkaline metal or alkaline earth metal. This heat transfer promotor is applied to that surface of a condenser tube to be contacted by a vapor to be condensed.
