Abstract
A fluid material application system is provided with an application deck for applying a fluid material that includes printing ink, adhesive or coating, a source of fluid material, a source of heat transfer liquid, and a heat exchanger. The heat exchanger includes a tube-in-hose ink heat exchange element having a fluid material carrying seamless tube located within a hose. The hose is adapted to be connected to a heat transfer fluid source so that a heat transfer fluid flows around the fluid material carrying tube to control and maintain the temperature of the fluid material in the tube at a generally constant temperature. The elongated heat exchange element may possess a winding type of configuration (e.g., it may be coiled or helically wound or may be laid out in a serpentine path) to define a winding flow path for the fluid material and the heat transfer fluid, and may be located within an enclosing structure to define an overall compact heat exchanger.
