PROTECTING YOUR GENERATING ASSETS SINCE 1932

GENERATOR AUXILIARIES

GENERATOR AUXILIARIES Lectrodryer’s Generator Auxiliaries unite the all the auxiliaries associated with conditioning, monitoring, and handling of the gases used in a Hydrogen-Cooled Generator. Its flexible modular design can include any combination of components specially designed to meet your specific hydrogen-cooled generator maintenance needs. The Lectrodryer Generator Auxiliaries promote safe and efficient operation by providing accurate timely readings result-ing in gas savings.

GENERATOR CONTROL PIPING SKID (GCPS) Purging of the generator demands an accurate timely operation to have a safe and efficient generator gas degas and refill. This system facilitates gas handling and ensures that only one type of gas is being supplied to the generator. The Generator Control Piping Skid includes a hydrogen auto make up system. Other options available include purging automation, air leakage auto-test, hydrogen totalizer and a Liquid Level Detector Rack.

GENERATOR FAST DEGAS CO2 SYSTEM (GFD) Lectrodryer´s unique design allows for quick degassing of the generator while preventing lines from clogging with dry ice due to the expansion of the CO2. The Generator Fast Degas CO2 System reduces the time and cost involved during forced outages by allowing the generator to be purged and brought back online much more rapidly. This system also provides a risk mitigation tool to evacuate hydrogen during dangerous upset conditions providing a flow rate of up to 236 SCFM (379 NCMH). The GFD includes a CO2 totalizer for monitoring CO2 consumption. When the GFD is coupled with the automated Generator Gas Monitoring and Control Skid (GMCP) a purge can be initiated from the control room and the progress can be monitored. It can be supplied with an optional Automatic Transfer Switch for alternate backup power supplies.

BAC-50 HYDROGEN DRYER The BAC-50 is a fully automatic, dual tower unit that utilizes regeneration type desiccant for the continuous drying of hydrogen gas even during turning gear. Reactivation is accomplished at operating pressure using a closed-circuit system resulting in no hydrogen purge loss. The BAC-50 is offered with inlet hygrometer which provides generator gas dew point information at case pressure. Pressure corrections are not required to provide real time and accurate data. Lectrodryer’s proprietary sample loop guarantees proper sample flow and prevents probe contamination. Additional options include outlet dew point sensor, OVF-6 oil vapor pre-filter, and a water discharge monitor.

GENERATOR GAS MONITORING SKID (GGMS) The Generator Gas Monitoring Skid integrates Gas Purity, Case Pressure and Fan Differential Pressure Information. It provides purity information of the generator gases including hydrogen, carbon dioxide (argon or nitrogen can be used in the place of carbon dioxide), air, water vapor, or mixtures thereof. Purity measurement operation principle can be by density with no hydrogen loss or thermal conductivity. Redundancy options available.
