Date Jun. 19, 1986.The subject matter of the invention is a device for supplying spray units for die casting machines each with a fluid containing water and additives for cooling, cleansing and lubricating purposes. The device contains at least one central tank (26,28) storing water comprising additives, whose concentration has been adjusted to a maximum. Said maximum value depends on casting materials, molds (18,20) and die casting methods which are carried out on the die casting machines (10,12). In another central tank (44) water is stored. The tanks (26,28,44) are connected to mixing valves (38,40) provided at each die casting machine (10,12). A pump is connected between the outlet of each mixing valve and the inlet of a respective spray unit at a die casting machine.
