Refined continuously through 4 thruster generations
Since 1965, we have delivered thousands of tunnel thrusters
for fishing, cruise, naval, merchant and offshore vessels –
a success story for generations.
We focus on developing ever more reliable, optimized
and cost-effective systems
• Enhanced gearbox for optimal hydrodynamic performance.
• Robust gear maintains optimum tooth contact
in various operating conditions.
• More compact propeller hub.
• Balanced backward skew blades minimize servo
and excitation forces.
• Replaceable blade bearing liners.
• Options for non-pollution seals and lip seal systems that
can be replaced without removal of the propeller hub.
• Underwater unit can be removed with propeller blades
in place.
• Pipe connections are easy to access.
• Pitch feedback unit includes a visible display.
• Shaft coupling enables easy installation and removal
of drive motor.
• Reduced weight of the gearbox, propeller hub
and tunnel – structural improvements ensure that
the thruster is just as rugged despite the lower weight.
• The tunnel is being optimized and strengthened
to reduce vibration.
• Nodular cast iron in the motor frame improves stability,
reducing vibration and noise.
