We are the first Portuguese company dedicated to the development and commercialisation of hydrogen purification technologies.


Amnis Pura, SA is one of the first companies dedicated to the development and commercialisation of hydrogen purification technologies, namely Pressure Swing Adsorption units (PSA).

Our strong R&D mentality dedicated to gas purification technologies allows us to develop and produce competitive solutions in line with the expansion of the hydrogen market in a circular and sustainable economy.

With the growing hydrogen market, Amnis Pura focuses on the purification of hydrogen from decentralised production processes such as ammonia cracking, methane reforming, waste and biomass gasification. Depending on their nature, these processes can be carried out under various operating conditions. They have different gas compositions that can vary over time during the production process. In this regard, Amnis Pura develops tailor-made solutions that are optimised specifically for the customer’s process, to meet the requirements of the strict ISO 14687-2.
