Vacuum sealing and maintaining the vacuum in condensers

Principle of operation and use

The function of Vacuum consists, firstly, in carrying out the initial vacuum in the condenser at a predefined level before starting the turbine in a defined maximum time and, secondly, in extracting the non-condensable gases, thus maintaining the desired vacuum in the condenser.

Since high suction capacities are often required and non-condensable gases are saturated with water vapor, liquid ring pumps are the technology primarily used for this application. Systems designed and manufactured by GEFI operate on all continents around the world.
