Abstract: A water distribution system is disclosed in an ink flow temperature control system of a plurality of printing presses such as multi-color offset perfecting and nonperfecting web and sheet fed presses. The system includes a plurality of printing presses each having at least one printing head whereat water is used to control the temperature of ink distributed through the head. A multiple zone control unit controls the temperature of water distributed to the printing heads of the plurality of printing presses. An enlarged rigid conduit extends between the multiple zone control unit and each printing press. A plurality of flexible non-metallic distribution hoses are located within the enlarged rigid conduit for distributing water between the multiple zone control unit and the printing heads of the plurality of printing presses.

Abstract: A temperature control system for a printing press or similar machine which includes an ink distribution roller for distributing ink to a printing couple. The machine includes a frame with a control zone for accommodating various control elements of the apparatus, with an opening in the frame for access to the control elements. A control system housing is pivotally mounted on the frame for movement between a first position closing the opening in the frame and a second position exposing the opening for access to both the control elements within the frame and various control components within the housing, such as a water pump, a water heater, valves and conduits within the housing for feeding controlled temperature water to the printing couple.
