TRESU installs 12 chilling units on fleet of HP Indigo 12000 Digital Presses

Press release from the issuing company

Kolding, Denmark - TRESU Americas announces the sale of 12 DPC5-6 iSeries chillers to a customer based in Arizona, USA to efficiently eliminate excess heat on its HP Indigo 12000 Digital Presses.

TRESU’s DPC (Digital Process Chiller) carries out the vital cooling of the digital engine, pumping heat away from the press, and exhausting it from internal environment to remote external condensers. Each chiller and condensing unit has a heat extraction capacity of 42.2kW (144,000 Btu/hour or 1.2 refrigeration tons) for cooling each press. The process of extracting heat generation from each of the presses is independent and does not involve the plant’s HVAC (heating, ventilation and air conditioning) system.

HP Indigo 12000 Digital Presses can print up to 3450 B2 (750 x 530mm; 29 x 20in) sheets per hour (4/0), using multiple lasers to image the impression cylinder for each colour. Combined with the press speed, the heat generated could inhibit drying, or adversely affect substrates. The presses are able to run papers up to 70g/m2 to 400g/m(50lb. to 150lb.) cover with thickness of 75-450 microns (3-18pt). The press can also print plastics, metallised laminates and synthetics.

The TRESU DPC iSeries Chilling System is designed to operate with HP Indigo Series 4 presses (HP Indigo 10000, 12000, 20000 and 30000 Digital Press series) and contains advanced features that make it an ideal complement to those presses. The system’s programmable logic controller (PLC) features touch-screen controls for ease of operation, while an Internal Diagnostic Monitoring System (IDMS) alerts the TRESU service department of any performance issues and enables remote access to determine the cause of the alarm, and enable swift remedial action to be taken.

“The installation of 12 TRESU DPC5-6 units at our customer has been one of the largest single installations of chilling systems undertaken by TRESU,” said Scott Hibbs, President & CEO, TRESU Americas. “Our partnership in the development of the iSeries chilling systems as well as our cooperation with HP Indigo on the iCoat coaters helped digital printers improve productivity, print quality and meet their customer’s requirements.”
