Water cooled steam condensers (WaCO)

from Wärtsilä

Water cooled steam condensers

Wärtsilä Serck Como water cooled steam condensers (WCC) are used in a steam cycle to condense the steam after the turbine. They close the water steam cycle and also create a vacuum on the outlet of the turbine which increases the efficiency of the turbine.

Our WACOs are completely assembled on a steel frame, including all necessary accessories, which guarantees a trouble free and easy installation on your plant.
