Roll Repair

Temperature control and stability is a key indicator of Heat Transfer Roll health. In today’s world of performance materials and adherence to international standards, uniform temperature control is essential, directly impacting line speed as well as product quality and consistency. If you’ve identified an issue with your heat transfer rolls, the decision to refurbish or replace is best made by first determining the cause of performance decline.

Basic maintenance of your heat transfer roll, such as running treated water through your roll or acid flushing on a regular basis, will help to maintain clean internal flow passages. When scale build-up, excessive corrosion, and blockages inside the roll are significant, roll refurbish may be a more economical option than de-commissioning or discarding the roll. At Mirror Polishing & Plating, our goal is to provide you a means to salvage usable components when possible. Removing the outer shell and reconditioning the internal components can be solutions.

At MP&P we offer an established inspection process for all incoming rolls.

Refurbishing your heat transfer roll can return production efficiency and product quality with a faster ROI than any other roll refurbish service. If the internal structure is intact and in good operating condition, the cost to reshell or refurbish an existing roll will be less than investing in a new heat transfer roll.
