Abstract
A temperature-control device particularly for an offset printing machine for at least two separate liquids in the machine. Dampening solution circulates in a first liquid circulation circuit to printing plates or the like receiving the dampening solution. A first heat exchanger communicates with a cold generator and the first liquid circulation circuit passes through a first heat exchanger. The second cooling solution of the printing machine cools parts of the machine and is in a second liquid circulation circuit. The second liquid circulation circuit passes through the second heat exchanger. After passing through the first heat exchanger, the first liquid circulation circuit also passes through a second heat exchanger, whereby heat is exchanged between the first and second liquid circulation circuits. The second liquid circulation circuit includes a controllable bypass for selectively bypassing the second liquid past the second exchanger. Another bypass in the first circuit selectively directs the first liquid to the printing plates or the like to which the first liquid is to be delivered or bypasses that first liquid application device. A third heat exchanger may provide cold to the second liquid circulation circuit.
