RH-AQG-III Hydrogen Dryer
Third-generation hydrogen drying and humidity control for generator hydrogen systems, with purification support and three-tower adsorption design.
Overview
The RH-AQG-III third-generation hydrogen dryer uses an innovative three-tower structure with intelligent operating control. During normal operation, the three towers alternate between drying, standby, and regeneration states. When humidity becomes too high, the standby drying tower can be brought into operation immediately, helping the system adapt to different generator operating conditions. This design supports hydrogen humidity control, hydrogen purity improvement, and safer, more efficient hydrogen-cooled generator operation.
