Vacuum pump is making vacuum in the condenser when the turbine generator operates, where the vapors scars that have been used to rotate the turbine side of the LP terakir will pass the last blade, to accelerate the condensation into the water again with a road in the condenser must be made vacuum, ie steam going down and touched the wall outside the condenser tube and a tube condenser dalan side is drained by the cooling media (use of seawater) pumped by CWP. Sehinnga with the heat transfer the wet steam is still temperate and touching the condenser tube wall will be condensed into water again and in the process is often called condensate water and will be accommodated within the hot wall.
