Closed-loop hydrogen dryer is the latest generation of adsorption dryer, especially suitable for occasions with strict requirements on regeneration gas consumption, especially when the dried gas is flammable, explosive, toxic or particularly expensive, and it is the best choice for users.
This series of dryers apply the principle of variable temperature adsorption and adsorb (work) at room temperature and high water vapor partial pressure; Analysis (regeneration) at high temperature and low water vapor partial pressure.
That is, the water adsorbed by the adsorbent in the adsorption process is completely removed by the thermal diffusion mechanism (dry gas heating) of high-quality regeneration gas in the regeneration process.
The heater is generally an electric heater, and compressor waste heat or steam can also be used.
