Direct Drive Underwater Thruster








DWTEK provides four direct-drive underwater thrusters. The key feature of the direct-drive series is designed to directly transmit torque from the motor without any reduction. Main benefits also include high torque, fast response, and low inertia. 


  • Low power and high torque 

  • Fast response

  • Power efficiency 

  • Over-temperature protection, over-current protection, signal zero-crossing protection

  • Internal isolation between the power supply and signal power supply system

  • Good value for the price 

  • Customized service is available


Underwater Thruster







DWTEK provides three magnetically coupling underwater thrusters. Their main feature is the absence of mechanical commutators, which naturally reduces shaft friction and inertia, and creates less noise. Also, there are no connecting shafts, which makes them easy to install and results in extremely low maintenance with high reliability.


  • Static seals: easy to  maintain and zero failure out

  • Easy installation to plug in-and-out

  • Over-temperature protection, over-current protection, signal zero-crossing protection

  • Gear reducer mechanism

  • Internal isolation between the power supply and signal power supply system

  • Customized service is available

Sensor PCG-1000


PCG-1000 is exclusively designed for subsea inertial positioning and navigation system. The device integrates Pressure, Compass, and Gyroscope into single unit. The pressure sensor has an accuracy of 0.05%FS. It outputs Depth (meter/feet), Heading, Pitch, Roll and Turn via protocol RS232. The protocol also allows users to define sampling rates of 1Hz, 5Hz, 10Hz, 25Hz, or single shot.

Furthermore, two output formats (Binary or ASCII). Al6061 -T6 with engineering anodized treatment housing increases capability in corrosion resistance.

  • Integrated pressure, compass, and gyroscope

  • 5 user-selectable measurement rate

  • Data directly readout in serial console

  • Instant plug-in & high resolution and reliability

  • Depth rating: 1,000m /3,000m

Servo TM2408


TM-2408 is a digital servo rotator and achieves up to 0.1° positioning accuracy in subsea applications. The robust electromechanical design achieves the extraordinary torque output of 7Nm. Its user-friendly evaluation software allows users to adjust and test speed and angle immediately. The unique modular design provides handy maintenance and replacement. The compact size and front view mounting offers an advantage in displaying system layout easily and simplifying installation. DWTEK also has several subsea coupling kits available for your application. Al6061 -T6 with engineering anodized treatment housing increases capability in corrosion resistance.

  • Programmable limitation of rotation angle
