Abstract
A device for controlling a printing temperature of an ink in a print head of a system for inkjet printing includes a heat exchanger with a first channel for ink and a second channel for a temperature control fluid; a chiller for heating and/or cooling the temperature control fluid; an ink circuit that is configured to pump ink through the heat exchanger and into the print head; and a temperature control fluid circuit that is configured to pump the temperature control fluid through the chiller and the heat exchanger. The device is configured to heat and/or cool the temperature control fluid with the chiller such that a temperature of the ink is set within a predetermined temperature range. At least one heating element is provided at the heat exchanger to heat the temperature control fluid and the ink to more rapidly set the ink within the predetermined temperature range.
