Servogear Ecoflow PropulsorTM is more efficient than any other known propulsion concept.Through continuous theoretical and practical research, Servogear has developed an increasingly efficient propulsion system which today is successfully running in a great number of vessels all over the world.
We achieve groundbreaking results through our all-inclusive approach. Our propeller tunnel allows for larger propeller diameter with no increase of shaft angle and draught. Propeller rpm is reduced, as well as the surface pressure on the propeller blades, and the water flow entering the propeller is optimised. Together with some other details, this provides the propeller with the best possible working conditions resulting in a smooth and optimum propeller thrust.
A more even loaded propeller gives a slimmer and lighter design, which means less weight and drag as well as higher efficiency. We calculate and design our propeller tunnels based on full utilisation of the flow below the hull, ensuring optimum interaction between hull and propulsor. Efficient propulsion means lower fuel consumption, more economic operation and less pollution.
Tank tests and full-scale verification tests have proven that the Servogear Ecoflow PropulsorTM is more efficient than any other known propulsors.
