To start a thermal power plant, a condenser must be brought from atmospheric pressure to vacuum. In some systems, requirements preclude the use of the condenser exhauster to perform this job. In these cases, a separate vacuum device is used.
Suction Capacity: 100 to 2,100 ACFM (170 to 3,600 m3/h)
Vacuum Range: to 0.8 inHgA ( to 30 mbar abs.)
Suction Capacity: 60 to 13,000 ACFM (100 to 22,500 m3/h)
Vacuum Range: 1 inHgA (33 mbar abs.)
