Water Cooled Brake
Water Cooled Brake is best suited for applications where continuous slip and high heat braking is needed. Pneumatic actuation is available in two forms: piston type and air tube type. The design of wear plates, made of top-quality copper alloy and composite materials, allows for good wear resistance and greater heat dissipation characteristics. It is designed to accommodate open or closed cooling system. This product is mainly used for auxiliary braking for drawworks of oil drilling rig and workover rig.
