How to improve engine efficiency and reliability in extremely humid conditions

The Wärtsilä Receiver temperature dew point control improves the efficiency and reliability of the engine’s operation while also lowering fuel consumption and emissions. The Wärtsilä Receiver temperature dew point control is a fully automated solution that dynamically adjusts the low temperature water flow so that the charge air is at the optimal temperature. This prevents condensation in the charge air receiver, thus preventing corrosion and reducing the risk of engine damage.

Benefits

  • Reduced risk of corrosion in the charge air system and inlet valves
  • Increased lifetime of the equipment
  • Improved fuel economy
  • Decreased CO2 and NOx emissions
  • Optimised smoke levels at low load
  • Installation can be carried out while the vessel is in operation

 

Technical info

The Wärtsilä Receiver temperature dew point control has been designed with standard components to cover various Wärtsilä 38, Wärtsilä 46 and Wärtsilä 50 engines configurations and water control systems.

  • One control cabinet and humidity sensor to be installed per engine room
  • The Wärtsilä Receiver temperature dew point control serves up to 4 engines
  • To be connected so as to control the 3-way valve of the low temperature cooling water
    • In installations with a controllable 3-way low temperature valve, the unit can be connected directly
    • In installations with wax element thermostatic valves, the valve and piping need to be modified to include a controllable 3-way valve.

Application

  • Wärtsilä 38, Wärtsilä 46 and Wärtsilä 50 engines
  • Other Wärtsilä 4-stroke engines as a customised solution
