converting temperature control units, chiller for converting industry

Converting companies also known as converters, are companies that specialize in combining raw materials in order to create a new product. Materials for converting processes can include: polyesters, adhesives, silicone, tapes, foams, plastics, felts, rubbers, liners and metals.

Some processes require materials to be produced in long continuous sheets such as paper, plastic film, foil and cloth which are rolled up for convenient handling and transportation. These rolls of material vary significantly in size and weight — ranging from 2 to 203 inches wide and weighing as much as several tons. The converting industry takes these continuous rolls of thin, flat materials — known as webs — threads them through processing machines (such as printing presses, laminating, coating and slitting machines) and converts or changes the web of material into an intermediate form or final product. This activity is known as web processing.

Common converting processes are coating, laminating and printing. Coating technologies can include hot melt coating, gravure coating, curtain coating and slot-die coating. These converting processes could require heating or cooling only or a combination of both. Converting rolls are also called chill rolls or heat transfer rolls.

Delta T Systems’ temperature control units and industrial process chillers are perfect to control the temperature of any roll used in the converting industry. The temp control units are connected with pipes or hoses to the converting rolls where fluid (water or oil) is circulated through the roll to keep the roll at a temperature set point.
