Abstract
A fryer unit combination includes a frying fluid vat and an associated heat exchange system whereby increased or greater efficiencies and/or heat transfers can be obtained and realized. The heat exchange system includes a first heat exchanger arrangement at least in part disposed within the frying fluid vat and a second heat exchanger arrangement disposed externally to the frying fluid vat. In the first heat exchanger arrangement, a heat exchange tube is in heat flow communication with a combustion chamber wherein an associated gaseous fuel burner is at least in part housed. The second heat exchanger arrangement includes at least a first side heat exchanger disposed externally adjacent the first side of the frying fluid vat. The side heat exchanger(s) may permit intake of an oxygen-containing gas such to preheat the oxygen-containing gas prior to entrance into the combustion chamber.
