Abstract

An assembly for controlling the temperature of a fountain fluid and/or selected drums of a printing machine comprises a fountain fluid circulating system for supplying a fountain fluid application means with a fountain fluid, a cooling fluid circulating system for supplying a drum cooling means with a cooling fluid, a first internal cold source which is in heat-exchanging relationship with the fountain fluid circulating system, a second external cold source which is in heat-exchanging relationship with the cooling fluid circulating system, and a means for selectively operating one of the circulating systems, for the fountain fluid or the cooling fluid, or both of these circulating systems. Further the condenser means of the first cold source is in heat-exchanging relationship with the refrigerant circulating system of the second cold source. The temperature controlling assembly thereby allows the requirements for cooling energy to be precisely matched to the currently effective operational mode.
