The Importance of Process Cooling in the Printing Industry

The Chiller Role

The result of modern machines working at higher speeds is that they use more energy. This usually leads to the emission of more heat. In most print equipment, excess heat is a problem for the following reasons:

  • At higher temperatures, the frequency of printed blackins decreases. Excessive emulsification of blackins leads to lighting and smelling of the print.

  • For printing, you may need an increase in the amount of black with low height. The use of a greater volume of black increases the cost of printing.

  • High heat levels increase the loss of the printing system, leading to more frequent technical maintenance.

Chillers play an important role in polyography. They are vital to ensure a stable temperature equipment, which, in turn, has a crucial importance to ensure quality and production speed. Most equipment manufacturers perform the circulation of cooled water through critical components, to reduce unwanted heat and provide a stable working temperature.

The heat load is usually captured by the circulation of cold water through printed bubbles or through ultraviolet lights.

Direct cooling of bubbles

The cooling bubbles provide the product cooling directly to maintain constant productivity. The cooled water passes through the rotor connections on each end of the bubble.

Cooling for UV and LED Lamps

UV and LED lamp systems are used to create ultraviolet light that can be directed to the surface for printing. UV light comes into reaction with wet blackness, leading to their fast fixation and drying. UV fixation method is widely used in modern and large printed systems, as the transmission capacity of printing can be significantly increased. Cold water usually passes through a heat exchange attached to the cabbage holders, andins a stable working temperature.

Cold in large printed enterprises

In larger printing systems, a centralized system is often used, in which the built-in heat exchanger is used to manage the cooling of the individual components of the line. Then for the primary cooling of the built-in heat exchanger, a placed external chiller is used.

The diagram below shows the typical installation of a large printer.

In many cases, the entire printed line is supplied by the company to create complex OEM systems to provide the customer with the necessary solution. In these lines, the black-blinding is usually used using UV lamps. Hyperchill and Hyperchill Plus coolers offer reliable and cost-effective solution and are perfectly suitable for meeting the needs of cooling UV systems.

Why the Parker Chiller?

Hyperchill and Hyperchill Plus chillers provide safe and reliable work in a variety of working conditions typical for the polyographic industry. Parker chillers' constructive features can bring end users significant advantages. Here are some key features and advantages of printing:

  • Hydraulic container of colored metals with a steel-based side, steel and water pump maintain the quality of the chlorogen.

  • High-precision water temperature control (up to ± 0, 5°C) thanks to the developed and tested PID software that provides the highest temperature stability even with variable loads.

  • The medium and high pressure inserts provide constant water and pressure in the equipment.

  • High reliability in combination with the rational use of energy to reduce the overall value of possession.
