Wärtsilä EnergoFlow
In today’s increasingly competitive shipping environment, you need solutions that not only increase your efficiency, but that are also reliable and have a short payback period. Wärtsilä EnergoFlow is an innovative and cost-effective pre-swirl stator that increases fuel efficiency by up to 10% – without increasing maintenance needs.
Wärtsilä EnergoFlow creates optimal inflow for the propeller by guiding one side of the stern flow in the opposite direction to the propeller rotation, generating pre-swirl. The solution consists of multiple curved fins and a ring attached to the ship’s hull to prevent the power losses that typically occur in a propeller’s slipstream.
