Condenser air removal
Continuously removes air and non-condensable gases to support the specified condenser operating pressure.
APPLICATIONS · POWER GENERATION
Stable vacuum for power-generation duties.
From turbine condensers to waterboxes and gland systems, liquid ring solutions are engineered around wet-gas load, air leakage, service liquid and redundancy requirements.
POWER PROCESS VACUUMWet gas + vapour loadProcess-specific architecture
VACUUM IN THE STEAM CYCLE
A separate duty point for every operating phase.
Condenser evacuation is not selected from ultimate pressure alone. Hogging time, continuous air leakage, saturated gas load, condenser pressure, service-liquid temperature and operating philosophy are considered together.
Hogging and holding
Start-up evacuation and continuous holding are treated as separate operating points.
Waterbox priming
Removes trapped air from cooling-water lines to support siphon establishment and limit air pockets.
Gland-steam exhaust
Handles excess steam and air, with condensate managed through separation and drainage.
WATERBOX PRIMING
Remove air from the cooling line in a controlled way.
A vacuum receiver, priming valve and separation arrangement help establish siphon while limiting water carry-over to the pump.
SELECTING THE RIGHT SYSTEM
Use the real plant load, not catalogue flow alone.
Pump and auxiliaries are designed as one system around four data groups.

APPLICATION ENGINEERING
The vacuum source is one part of the complete system.
Reliable performance depends on the pump or blower, protection equipment, line arrangement, controls and the real process operating point.
Operating point
Capacity and pressure are checked together at the actual inlet conditions and duty cycle.
Share Operating DataProtection equipment
Filters, separators, condensers, receivers and valves are selected around moisture, particles, liquid carry-over and process risk.

Pipework, controls, isolation, accessibility and redundancy are included in the final system architecture.
