Simplicity and Flexibility
GE’s air-cooled generators are an ideal choice for power system applications that demand simplicity and flexibility of operation. Air-cooled generators operate with either an open-loop or a closed-loop cooling system. Under the open-loop system, the generator draws air from the atmosphere to cool itsactive components, then it exhausts the air back into the atmosphere. Under the closed-loop system, cooling air is recirculated continuously through the generator while air-to-water heat exchangers remove heat from the air.
