In addition to manufacturing an extensive range of ultraviolet curing lamps, Primarc UV Technology also supply high quality replacement quartz cooling tubes for both water-cooled and air-cooled systems.

Cooling tubes are designed to filter out infra red radiation and are mounted between the UV lamp and substrate. Using cooling tubes on ‘lampheads for drying ink between the application of different colours is said to offer a major advantage in that the heat on the substrate is minimised which reduces the potential for registration problems. The use of cooling tubes is believed to be particularly valuable therefore when printing on heat sensitive and lightweight substrates such as plastic, foil and film. The tubes are also reported to filter out IR radiation, ensuring that the machine never gets too hot or heat damaged.

Whilst requiring minimal maintenance, cooling tubes need to be kept clean to maximise performance. Keeping the tubes clean can be relatively straightforward, as there is normally no air extraction over the tubes to introduce contamination.

The tubes can be maintained in peak condition by occasionally cleaning with a soft cotton cloth doped with iso-propanol. In order to maintain the purity of the tubes, only de-ionised water should be used in water filtered systems (Plate 8).
