COMPANY HEADER
WPT® Steel Water Cooled (SWC) Brakes are designed for high-heat applications, such as coil processors and high-cycle press / shear lines. The unique design of the steel water jackets allows for the rapid transfer of heat to an external cooler or recirculation system. This increased heat transfer capabilities allow the Steel WCB to operate in continuous slip applications. WPT®'s Steel WCBs are available in 1, 2, or 3 plate configurations with sizes ranging from 6 through 30 inches.
