ON2Quest’s hydrogen de-oxo dryers efficiently remove residual oxygen and water from high-purity hydrogen streams. Commonly used for upgrading electrolyser product gas and recovering spent industrial gases, they come in two types: closed loop for optimal hydrogen recovery and open loop for minimal energy use. Standard systems handle flow rates from 5 to 2,000 Nm³/h, delivering product streams with less than 5 ppm oxygen and water.
