I plant the production XH-9 is developed for the mixed refrigerant such as HFC-152a of DuPont SUVA P39 and MP52. It provides a better performance, and to comply with the desiccant: chemical compatibility required for automotive and stationary refrigeration systems; high water absorbing capacity; higher particle crush strength; dry anti-wear ability; anti-wear ability of the hydrated; no air released.
