Customised Blower and Vacuum Packages

This is an air removal system in a power plant. The unit removes air and gas from the steam side of the condenser. It consists of three liquid rings vacuum pumps (RVS 40), mounted on a skid, including piping, valves, non-condensable tank separator, seal water cooler, controllers and ejectors for the first stage. All these components are controlled and monitored directly from the control room or through remote control. The pumps are supplied with an ejector with bypass, in order to reach the requested operation conditions even with sea water as cooling liquid. Service liquid is cooled through a heat exchanger avoiding all contact contaminations between cooling and service liquid. A special alloy is used in the machine to validate its use with sea water as cooling liquid. The package capacity is 51 kg/h of saturated air at a pressure of 40 mbar and equipped with three motors of 55 kW.
