SPE/PEM technology electrolysis use world advanced Proton Exchange Membrane technology, only use little electricity and pure water, to produce pure hydrogen gas. No need to add KOH. We mainly produce five types now, round shape have: SPE-90 small with H2 flow 0--90ml/min, SPE-300: H2 flow 0--300ml/min and SPE-600:0--600ml/min. SPE-1200plus round type and SPE-2000plus round Square shape have: SPE-600plus: 0--600ml/min, SPE-1200plus: 0--1200ml/min and SPE-2000plus with H2 flow 0--2000ml/min. It is widely be used in Hydrogen generator, people breath and rich hydrogen water to drink etc.
