Wärtsilä 46 and 50DF liquid fuel engines

Wärtsilä 46 & Wärtsilä 50DF* liquid fuel power plants

High efficiency and power on any liquid fuel combined with high reliability and flexibility make this solution perfect for flexible baseload applications including daily starts and stops, also providing ancillary services like up– and down– regulation.

  • Most efficient simple-cycle liquid fuel solution, up to 47% efficiency
  • Can operate on any liquid fuel, including HFO, LFO, liquid biofuel, crude oil or fuel-water emulsions
  • Robust, reliable genset, proven in the most challenging environments
  • Most compact HFO power plant in terms of footprint

*This Wärtsilä 50DF plant is optimized for liquid fuel operation, providing the same features as the Wärtsilä 46 plus the option to switch to gas when it becomes available.
