Submersible Direct Drive Pulley Belt Generator.

AquaGen is an all-in-one power take-off solution to generate power in subsea environments. The generator contains a direct drive custom-designed alternator and uses no shaft seals or oil in its’ drive train. The lack of a gearbox or any mechanical meshing components within AquaGen ensures the products longevity, reliability, and continued power generation, in severe operating environments.

A programmable microcontroller, RS232 communication, and shaft position sensors provide options for real-time position updates, or load-latching control algorithms to be implemented into AquaGen. In addition, the hermetically sealed all-in-one generator eliminates the necessity for sealed hulls to house complex power take-off systems, therefore reducing capital costs of water based energy devices.
