11/01/1995. Hydrogen dryers. BAC-50 hydrogen dryer for hydrogen-cooled generators is a dual-absorber unit that continuously removes moisture from recirculated hydrogen, keeping the internal components of the turbine in a completely dry hydrogen atmosphere. The unit uses regenerative type desiccant and is fully automatic in operation. It is heat reactivated with embedded electric heaters. BAC-50 accomplishes reactivation with a completely closed-circuit system, thereby eliminating any purge loss or infiltration of atmosphere into the system.
