Abstract
In an assembly for controlling the temperature of a fountain fluid and/or selected rollers of a printing machine, which includes a fountain fluid circulating system, a cooling fluid circulating system, a refrigerant circulating system, and a means for selectively operating one or, simultaneously, more than one of the circulating systems, a common heat exchanging means is provided. The common heat exchanging means comprising a plurality of flow passages disposed in heat exchanging adjacent relationship with each other, and a distributing means for connecting each of the circulating systems to a selected series of flow passages of the common heat exchanging means. Adjacent flow passages can be connected to different circulating systems for heat exchange therebetween. The temperature-controlling assembly therefore can be operated in different heat exchanging functions.
