A method and an apparatus for producing a continuous liquid flow at a controlled temperature. The apparatus includes mixers (1, 2) which, upstream, are connected to a supply conduit (3) for hot liquid under pressure and a supply conduit (4) for cold liquid under pressure. Each respective mixer has an outlet (5, 6) connected to a common discharge conduit (9) by a first outlet conduit (7, 8). The common conduit (9) is provided with a tap (10) disposed downstream of the interconnection of the outlet conduits with the common conduit (9). The temperature of the liquid which is to be discharged through conduit (9) is adjusted in that hot and cold liquid are mixed in the mixers from which the liquid is supplied to the common conduit (9).
Apparatus for supplying liquid at a controller temperature comprising first and second mixers, a supply conduit for hot liquid under pressure connected to each of said mixers, a supply conduit for cold liquid under pressure connected to each of said mixers, central operating means connected to said mixers for controlling said mixers to supply mixed liquid at determined temperatures at respective outlets of said mixers, first and second outlet conduits respectively connected to the outlets of said first and second mixers, a common conduit connected to said first and second outlet conduits to supply mixed liquid from both said mixers as a combined liquid outflow externally of the apparatus through said common conduit as a first discharge conduit, temperature sensing means in said common conduit connected to said central operating means for control of the mixers, and a tap in said common conduit.
