ABSTRACT:
An assembly for temperature control of a fountain (dampening) fluid and/or selected rolls of a printing press, comprising a first open-circuit circulating system (U.sub.I) for supplying a fountain fluid application mechanism with a fountain fluid from a fountain fluid reservoir and a second closed-circuit circulating system (U.sub.II) for supplying a roll cooling mechanism with a cooling fluid. Each circulating system (U.sub.I, U.sub.II) is assigned a heat exchanger (3,4). The heat exchangers (3,4) receive refrigerant from a refrigeration mechanism having a power-switchable compressor (10) including a refrigerant return, thus enabling a refrigeration output to be adapted to demands in selectable operating modes "fountain-fluid cooling only", "cooling-fluid cooling only" or "fountain-fluid and cooling-fluid cooling".
