Inside a heat transfer roll, corrosion and other suspended matter can eventually clog inner-fluid flow channels and impede proper cooling or heating. Many of these heat transfer rolls can be refurbished by PFE Rolls through a reshelling process to achieve like-new performance. While reshelling can include machining inner and outer roll surfaces, inner spiral replacement, shaft repair and balancing, the cost can be a third that of a new roll. Still, reshelling is not for every heat transfer roll.
Some larger rolls with expensive outer shells are better replaced than reshelled. PFE Rolls manufactures and refurbishes heat transfer rolls up to 65 inches in diameter and up to 540 inches in length.
