The Enapter dryer raises the output purity of hydrogen gas from the AEM electrolyser to >99.999% in molar fraction. It is a hybrid temperature/pressure swing adsorption system that comprises two cartridges filled with a highly adsorbent material. The system is fully integrated into the Enapter Energy Management Sytem (EMS) to monitor the state, temperatures, and pressures.

The dryer will be installed at the H₂ outlet of the electrolyser and extracts the water from the hydrogen stream by releasing about 15NL/h of strongly water vapor saturated hydrogen via the purge line.
