controllable pitch tunnel thruster

Tunnel Thrusters are Fixed Pitch Propeller or controllable pitch propeller thrusters. The features
as follows:

-Superior Strength

Tough and rational structural design has accomplished superior strength ,Especially strong and
durable driving shaft and seal are adopted for longer operation.

-Less Noise and vibration

Employing thicker duct plate, developing new propeller design and so on have achieved less
noise and vibration which follow comfortable living environment on board

-Easy Installation and Periodical Inspection 

 is especially reduced duct lip and has a structure that it is able to weld anywhere on outer
surface of duct for installation, On the periodical inspection, it is almost

not needed to change parts except seal.

-Various type of driving

Compact new control system can provide easy operation. Customer can choose various
configuration of prime mover, electric motor, diesel engine or hydraulic motor.
