The nozzle has a particularly small outer diameter. This enables it to be optimally adapted to a wide range of ship designs and applications. At the same time, the high-performance nozzle is also suitable for conversions and upgrades with limited installation space. The SDC40 excels with the highest free sailing efficiency in transit at higher speeds. In addition, a higher maximum speed can be achieved.įurther nozzles are available on a project-specific basis.ĭuroVario allows SCHOTTEL to offer fully integrated clutches, optimally adapted to the propulsion properties of the respective propulsion system. Customers benefit from an above-average service life, which goes hand in hand with high service and spare parts availability. The compact and space-saving clutches also enable easier integration into a wide range of ship designs and straightforward installation thanks to plug-and-play setup.ĭepending on the type of clutch, the engine power is transmitted either by a simple on/off function or a convenient slipping function. The SCHOTTEL portfolio has the perfect solution for any application – all from a single source: DuroVario-DĭuroVario-D is a standard clutch that ensures a safe and durable connection between the propulsion unit and the engine. The SDC40 sets standards in terms of compact design and free sailing efficiency, thus also reducing operating costs compared to nozzles from other manufacturers. The high-performance nozzle is also characterized by optimally designed propeller geometries and outstanding performance features. The SDV45 is suitable for use in a wide range of operation profiles. The SDV45 combines proven higher efficiency during free sailing with excellent bollard pull values. In conjunction with optimally designed propeller geometries, the nozzle is able to fully utilize the outstanding performance values. Assuming the same propulsion power, the bollard pull is higher than the thrust of previous nozzles, while efficiency is significantly enhanced in the medium and higher speed range. This makes a major contribution to fuel savings. The new nozzles are equipped with the exclusive ProAnode technology from SCHOTTEL as standard. High-performance nozzles from SCHOTTEL are used in various types of vessels and applications to boost the propeller’s thrust force. Based on decades of propulsion expertise, SCHOTTEL VarioDuct (SDV) and SCHOTTEL CruiseDuct (SDC) feature impressively high outputs during free sailing and excellent bollard pull values. Part of this is the state-of-the-art technologies used to ensure the high performance characteristics of the nozzles.
SCHOTTEL propulsion units equipped with the LeaCon sealing system comply with the VGP regulations of the US-American Environmental Protection Agency (EPA). There is no need to use bio oils (EAL). In addition to the leakage-free sealing against seawater, the LeaCon system is used to monitor the condition of the seals. It registers the amount of leakage collected and continuously checks the condition of the seals. This means that operational wear can be detected at an early stage and unscheduled maintenance can be avoided. SCHOTTEL LeaCon is a sealing system certified by DNV-GL which offers safe and reliable protection against contamination of the seawater by operating materials. Separate seals to the seawater and to the gearbox side ensure that both incoming seawater and escaping gear oil are collected in an intermediate chamber (LeaCon chamber). This effectively prevents water from entering the gearbox and, above all, oil from escaping into the seawater. With the connected vacuum system, the leakage fluid is automatically collected in a compact tank in the engine room. If you cannot identify your application in the “Typical applications” section or if you have a vessel with a special area of application, SCHOTTEL will be happy to determine the most suitable propulsion unit for you. The final choice of propulsion unit depends on the actual operational profile of the vessel and is determined by SCHOTTEL. The ratings given are based on experience in the typical areas of operation of the respective vessel types. They do not apply to ice-classified ships.
