Ducted Propeller
Our ducted propellers are precision-engineered to deliver unmatched thrust and maneuverability for vessels operating in challenging conditions. Encased in a streamlined duct, this design amplifies propulsion efficiency by accelerating waterflow through the propeller, making it ideal for tugboats, trawlers, and ice-class ships. The duct minimizes turbulence and cavitation, ensuring stable performance while protecting the blades from debris and impact. Crafted from high-strength Ni-Al Bronze (Cu3), our propellers withstand corrosive environments and heavy loads, offering extended durability even in icy or debris-filled waters.

Why Choose Our Ducted Propeller?
Superior Thrust in Confined Waters:
The duct design maximizes thrust efficiency by up to 20%, perfect for vessels requiring precise control in ports or narrow channels.
Cavitation & Vibration Reduction:
Optimized blade-duct interaction minimizes noise and wear, prolonging engine and propeller life.
Debris Protection:
The duct shields blades from floating debris, reducing downtime in congested or icy waters.
Adaptability:
Customizable for ice-breaking, trawling, or heavy towing operations with reinforced ducts and blade coatings.
Q&A
Q: How does a ducted propeller improve performance compared to open propellers?
A： The duct accelerates waterflow through the blades, boosting thrust efficiency by 15-20% and reducing energy loss. This is critical for vessels needing high bollard pull, such as tugs or offshore supply ships.
Q: Are ducted propellers suitable for ice navigation?
A： Yes. Our reinforced ducts and anti-icing blade coatings prevent ice buildup and damage, making them ideal for ice-class vessels operating in Arctic or subzero conditions.
Q:What maintenance advantages do ducted propellers offer?
A: The duct acts as a protective barrier, reducing blade damage from debris. Additionally, lower cavitation means less surface erosion, simplifying inspections and extending maintenance intervals.
