In the USA where most fluxes are at about 70 C. The quench water
(cannot contain chromate or other treatments) is used in the flux tank for evaporation losses. This can be done because quench only picks up zinc chloride and ammonium chloride that comes originally from the flux. Again remember that if you have chromate or other chemical treatments in the quench you cannot do this this.
