A chill roller and a heat transfer roller are types of rollers used to regulate the temperature of materials, webs, or products during processing. Essentially, any roller that transfers heat—whether by adding or removing it—can be categorized as a heat transfer roller. These rollers go by various names, including chill rollers, heated rollers, water rollers, and chill rolls, depending on the user or manufacturer. Typically, a “Roller sejuk” is designed to cool or “chill” a product. In contrast, “Roller pemindahan haba” is a more general term that refers to rollers capable of either heating or cooling a product. In some applications, a single roller may serve both functions, allowing a customer to use it for cooling one day and heating the next, depending on their specific needs.
