The new SCHOTTEL VarioDuct SDV45 high-performance nozzle is now available in the Rudderpropeller range from the German propulsion specialist SCHOTTEL. It offers provable higher efficiency at open-water speed combined with very good bollard pull values.
In conjunction with optimally designed propeller geometries, the outstanding performance characteristics of the nozzle come to the fore. Given the same propulsive power, it has a greater bollard pull than the thrust of previous nozzles and, at the same time, offers considerably greater efficiency in the medium and high speed range. The system, consisting of a Rudderpropeller and the new nozzle, thus contributes significantly to fuel savings.
The new nozzle, with its compact geometry, offers considerably greater power than standard nozzles, such as the Wag-19A; it can also be optimally adapted to different vessel designs and applications. The small outer diameter also makes the nozzle ideally suited to shallow-water operation.
