Higher efficiency, less noise

SCHOTTEL CoaGrid

The proven SCHOTTEL Pump Jet, which is particularly suitable for shallow water operations, is now optionally available with a new feature: the SCHOTTEL CoaGrid.

This exploits the Coandă effect, which describes the tendency of a fluid to stick to a curved surface. In combination with in-house CFD optimizations a new streamlined geometry below the pump jet housing has been developed. This allows the water flow to be better directed into the inlet of the pump jet, leading to higher efficiency and lower noise emissions.

First propulsion units with the new CoaGrid are already reliably in service in passenger vessels.
