Piovan no longer differentiates between TCUs and chillers, said Giorgio Santella, the chief marketing officer for Piovan. “When it comes to injection molding of plastic parts with high perfor-mance, the solution we always offer is the DigitempEvo,” he said. “It’s a combination of the two.” Unlike other TCUs, the DigitempEvo does not require a chilled water source. The DigitempEvo has an internal cooling source, which means injection molders need only pipe dry-cooler or tower water into the DigitempEvo. The unit then chills the fluid, if necessary, to the exact temperature needed to cool the mold.
The Aquatech system saves energy by chilling the water only by the amount necessary to maintain the proper mold temperature, Santella said. In addition, since each DigitempEvo cools one mold, it eliminates the need for insulated piping to be run through an entire manufacturing plant. In a conventional scenario, a processor could have each injection molding machine equipped with one or more TCUs (depending on the size of the part that is being molded) along with a central chiller water system.
Precise flow rate and temperature and pressure control are necessary when a manufacturer needs to produce parts with high performance standards. It’s suited for technical applications
in such fields as the automotive and medical industries.
