The Generator Gas Dryer (GGD II) is a microprocessor-controlled, dual-chamber system designed for hazardous locations to continuously dry and recirculate generator cooling gas, preventing corrosion, diminished efficiency, and forced outages caused by water, oil, and other contaminants. It maintains low dew point levels to reduce windage losses and increase efficiency—even when the generator is on turning gear—using an automated, self-monitored column regeneration process triggered by programmable dew point levels or a secondary time-based backup (0 to 30 days). Featuring a standard electrical actuator and a compact footprint (29.75″ w x 83″ h x 38″ d), the GGD II ensures comprehensive contaminant removal, reduced downtime, and optimized generator performance.
