FHD(AHD) *Our AHD series features a two-way valve configuration

FHD: No Power Required

Our power source-free FHD series dehumidifying equipment, using either atmospheric air drawn in by an ejector or dry purge air to regenerate the desiccant, offer a unique advantage over conventional air dehumidifying equipment. Their ability to steadily supply dry air at a low dew point makes our FHD series dehumidifying equipment the perfect choice for semiconductor production facilities and other applications that require high quality gases.
