WPT Power and our local distribution partner, has implemented a solution of a WPT Power – Copper Water Cooled Brake (CWC) in place of a caliper disc brake in a controlled tensioning application. The OEM-fitted caliper and disc weren’t providing consistent tension to a large paper unwinding drive; due to the prolonged engagement time required, the caliper’s friction material was simply overheating and losing torque, resulting in inconsistent rolls, which affected production and product quality. WPT Power, our distributor, and the mill collectively worked over the drive details and loads and determined that an air-cooled unit, be it a caliper or a multi-plate air-cooled brake design, wasn’t suitable in this instance.
WPT Power put forward the most effective and efficient solution while working with the existing shaft size and the available dimensional envelope to minimize any modifications. This solution is a WPT Power CWC brake, which was proudly built at our facility in Wichita Falls, Texas, USA, and shipped over. The WPT Power, air tube actuated copper water cooled brake, provides precise engagement and torque control, while mediating the friction temperature with the constant flow of water through the brakes integral water jackets. This maintains a stable friction material temperature, which provides consistent performance for prolonged periods and a much increased service life, which is exactly what the paper mill wanted to achieve.
WPT Power also uses high-grade copper plates to ensure the maximum service life of the copper itself and the opposing friction material. We also supplied the client with a convenient rebuild kit, ensuring the brake can be serviced quickly and efficiently when it requires servicing in the future. The cost of this upgrade will be quickly offset (ROI) by the reduction in downtime and parts, material wastage, and an overall more efficient production flow within weeks.
WPT Power prides itself on providing solutions for existing equipment, replacement units and parts, and custom OEM solutions.
