Higher efficiency with the Contra Rotation Azimuth Thruster ZF Azimuth Thrusters allow unmatched maneuverability for all types of ships in commercial applications. The Contra Rotation Azimuth Thruster is a rudder propeller with contra rotating propellers. The lower blade load leads to reduction in noise and vibrations and ensures high sailing comfort. The thruster can be found in high performance applications as river going passenger vessels. The thruster is designed with a performance range of 150-770 kW. Advantages Higher efficiency with same propeller diameter Same efficiency with reduced propeller diameter Full thrust throughout 360˚ Improved sailing comfort Reduced fuel consumption Compact and solid design though ZF ease-off gear concept Beneficial for shallow-draught applications Reduced noise due to lower blade load Possibility to operate the thruster with biodegradable lubrication oil Available with Condition Monitoring System Function All ZF Azimuth Thrusters are developed and produced in-house and thus, can be customized according to the customer’s wishes. Z-drive or L-drive Control system ThrusterCommand is integral part of the propulsion system Possible Mounting configurations Well mounted from top Well mounted from bottom Weld-in Well shape and height can be chosen to best suit the vessel design Standard well shapes Round Rectangular Hexagonal Drive options Diesel engine, using upper gearbox and wet or dry clutch (Z-drive) Electric motor, both horizontal (Z-drive) and vertical (L-drive) Hydraulic motor (L-drive) Steering of the thruster Electric or hydraulic steering Cooling Sea water Fresh water Propeller Counter rotating fixed pitch propellers
