Brunvoll RDT2100 – a new rim driven tunnel thruster

Brunvoll's Rim Driven Tunnel Thruster meets environmental concerns with its efficiency, low noise and high reliability

Brunvoll launches a new unit in our series of Rim Driven Tunnel Thruster (RDT)

The latest unit in Brunvoll’s thruster familiy is the RDT2100 – a rim driven tunnel thruster of 2,1 meter propeller diameter and a power range up to 1600 kW.

RDT2100 is a result of the market demand, and the first units are for an SOV-project.

A rim driven thruster is eqiupped with a permanent magnet (PM) motor integrated in the thruster unit.

The PM-motor operates at a low speed and is combined with a large ring propeller with a high number of blades.

The Brunvoll RDT is hence a compact and low-noise thruster.

As for all Brunvoll thrusters emphasis has been put on designing a competitive thruster with low life cycle costs.
