For the tidal energy industry, these ‘wet’ brakes generate torque through shearing of the oil layer with negligible lining wear, making them suitable for the low maintenance requirements of sub-sea installations. The Wichita Clutches can meet the power transmission challenges of the growing tidal turbine industry. Similar ‘dry’ units are also available, including water-cooled versions for high-energy stop applications.

The Twiflex Ltd. line of spring-applied and direct-acting, pneumatic or hydraulic, caliper disc brakes provide routine dynamic stopping, holding or emergency stopping functions. Models may be customized with a variety of features and finishes suitable for tidal turbine drive applications and packaged with discs and controls where required.
