I-cooler ye-transformer nganye ixhotyiswe nge amanzi ukuvuza umtshini. Ekubeni umbhobho we-cooler ye-transformer ngumbhobho we-double-layer, xa amanzi ukuvuza kwenzeka kumbhobho wangaphakathi we-heat exchanger ye-cooler, isixhobo siya kuthumela isignali ye-alamu. Unokujonga ukuba kukho ukuvuza kwamanzi ngokujonga kwifestile yokuhlola kwisixhobo sokujonga ukuvuza kwamanzi.
