Add to compare

Enapter’s dryer is a hybrid temperature/pressure swing adsorption system for further purification of green hydrogen (to >99.999%). The dryer is maintenance free and employs a pair of cartridges filled with a highly adsorbent material. During operation, one cartridge catches the humidity from the hydrogen gas stream of the electrolyser, while the other cartridge is heated and regenerated to discharge humidity. The dryer is rack mountable in a standard 19” cabinet and easily integrated with modular Enapter AEM Electrolysers.

      Enapter is a rapidly growing company based in Pisa, Italy with offices in Germany, Thailand, and Russia. The company develops and manufactures the patented anion exchange membrane (AEM) electrolysers for hydrogen production from water and electrical energy. Hydrogen is considered the most important element to replace hydrocarbons such as gas, oil, coal, and all fossil fuels. Green hydrogen is made with electricity from renewable energy sources. Hydrogen is an energy carrier useable to satisfy heating or cooling needs, mobility in the transport sector, or to provide feedstock in industry. A mass-produced AEM electrolyser will become a commodity and compete with fossil fuels purely on price.
